Was it Really independance Essay Example For Students

Was it Really independance Essay The American Revolution was forced upon the Americans by the crueltreatment from the British. On May 10 of 1775 the Second ContinentalCongress gathered in Philadelphia, one month after the fighting broke out. There, delegates from each of the 13 colonies would decide on independence. A Declaration of Independence was required to state why the 13 colonieswere separating from the British Empire. With this, POWs could demand tobe treated as prisoners instead of traitors and aid coul d be sought fromBritains enemies. The Declaration of Independence consisted of thepreamble, the middle section and a section declaring independence. Themost important part, the preamble, justifies the rights of the Americancitizens. It declar es that men are created equalandare endowed bytheir Creator with certain unalienable rights; that among these are life,liberty, and the pursuit of happiness. That sentence still remains atruth with the Americans today. Jefferson wrote the preamble with the helpof John Locke and Rousteu. Within the preamble Jefferson writes that thepeople, to secure these rightswhenever any form of government becomesdestructiveit is the right of the people to alter or abolish it. Itgives the people of America the freedom to impeach untrustworthy rulers anddictators i f they wish to. The freedom that Thomas Jefferson gave us isstill in practice today. The middle section justified why the colonistswere revolting against the Britis h Empire. Here Jefferson writes that theKing of Great Britain is a history of repeated injuries and usurpations.He reminds the reader that the King has refused to allow the Governors topass important laws necessary for the public good, obstru cted theadministration and that the king is sending over large armies to completethe works of death. The third section officially declares independence inwriting. The entire effort to complete the Declaration of Independence wasdone by Thomas Jefferso n, John Adams, Ben Franklin, Roger Sherman andRobert Livingston. In order to pass the declaration all of therepresentatives had to vote yes for independence. In one of the earlierdrafts a statement roughly 175 words gave black slaves independence .

A Fight for Racial and Gender Equality Professor Ramos Blog

A Fight for Racial and Gender Equality Emma Hurtado English 261 25 February 2019    â€Å"The Yellow Wallpaper† by Charlotte Perkins Gilman shows the harsh realities of what life was like for some women. Although women were beginning to experience some freedom, their husbands still had a say in what they did, which means they wouldn’t take into consideration what their wives wanted or needed. It is learned that the narrator is suffering from mental illness who feels that she would be better off experiencing freedom and going out to help with her illness. Unfortunately, her husband John, who also happens to be her doctor, feels that it is best to isolate her in her room with very little outside contact. Although she tries to voice her feelings and opinions, she is quickly shut down by John. By the end of the story, the wallpaper has driven her insane, making her feel as though the wallpaper has actually trapped women which symbolizes how she feels about her marriage. Society has come a long way since this story was written, but the conflict presented in â€Å"The Yellow Wallpaper† is still one that is relevant today. Society has managed to find a way to continue oppressing women in a way that is detrimental to women’s health and their children. The difference between both conflicts presented is the difference in social class and racial group. Charlotte Perkins Gilman writes from the perspective of a white woman who belongs a rich, upper middle class. Gilman’s purpose for writing this story was to share her experiences in hopes of changing the future for all women. This goal of hers was accomplished, but to a certain extent. Although society has progressed a lot since the late 1890’s, we can still see this conflict today in lower-income families and communities. There are groups of women who are still struggling with their mental and physical health due to not being listened to by their health care professionals. Great strides have been made in the last hundred years, but there are still various consequences that have resulted from the original conflict presented in â€Å"The Yellow Wallpaper†. The lives of women of color are still at risk today, regardless of their economic status. The connection between both conflicts is the internalized racism and misogyny that is still alive and present in society today. Some of the ways in which Gilman’s story is interesting is because of the way the narrator does not have a name and also because it only focuses on what life was like for women who belonged to an upper class. The narrator having no name really stands out and it seems that Gilman chose to do this to represent the rest of women in society at the time, not just one specific group of women. The narrator doesn’t want to acclimate to a life where she won’t get the help she needs or won’t be able to engage in the activities she enjoys doing. She notices how the women in her life are unlike her, in which they are willing to do whatever their husbands and society tell them to. She is cautious around Jennie, her sister-in-law, because she believes Jennie â€Å"thinks it is the writing† that made the narrator sick (Gilman 423). The narrator had to hide who she was and what she did because she feared that her own family would send her away to Weir Mitchell to receive a different kind of treatment. This conflict is not unusual today and still exists for women of color and lower income families. Although today the situation is different, society has managed to find a way to continue to oppress women in certain communities. One consequence of this is that â€Å"African American women are three to four times more likely to die from childbirth than non-Hispanic white women, and socioeconomic status, education, and other factors do not protect against this disparity† (Novoa and Taylor). There are several different factors that come into play, but one of the main ones is mental health. â€Å"Maternal mental health issues among African American women are largely underreported† (Novoa and Taylor). For a number of different reasons, most women aren’t able to ask for help just like the narrator in Gilman’s story and the results have shown that it has taken a toll on these women and their families. In â€Å"The Yellow Wallpaper†, the narrator conceals her pain and suffering because of the way society views women as being incapable of expressing their needs. At the beginning of the story, the narrator reveals how â€Å"John laughs at me, of course, but one expects that in marriage† which shows the way in which this kind of toxic behavior is normalized (Gilman 419). Because of these expectations, it shows why she would avoid bringing up anything regarding her mental health. At one point in the story when discussing the narrator’s recovery, she tries to divert the subject to talk about her mental health but as soon as she began, she stopped short, for he sat up straight and looked at me with such a stern, reproachful look that I could not say another word† (Gilman 425). This kind of conflict can still be seen today in a hospital where some women continue to receive horrible care. In both of these situations, the husband and doctors would be expected to do everything in their power to help these women, but unfortunately it does not work out too well for either group. A recent incident from 2016 shows how an African-American woman Simone Landrum experienced a difficult pregnancy but â€Å"she recalls, her doctor told her to lie down - and calm down† making her feel as if â€Å"he threw me away† (Villarosa). Unfortunately, a few days after being sent home, she was back in the hospital with the exact same pain but this time it resulted in her losing the child and the nurses mentioned that she was sick and â€Å"very lucky to be alive† (Villarosa). Both the narrator and Landrum were trying to receive the help they needed from the doctors but instead they were ignored which resulted in the narrator going insane and Landrum losing her baby. Gilman was criticizing the way men would belittle not just women’s health, but also any other small detail about their lives. Women weren’t regarded as equals because men were always the ones who held power in society. Much has changed as shown in current events, but not enough are focusing on all women and the different struggles they experience. One of the struggles that is common now are black women during their pregnancies. The conflict in the story was originally targeted towards all women but now it is much more common in lower social and economic classes and colored women. According to collected data, Kacey Eichelberger states that â€Å"black women face across their reproductive lives and conclude that these outcomes are not only statistically significant, but morally significant and fundamentally unjust† (Eichelberger 1771). These women experience twice as many risks than a white or Hispanic woman would. There are several factors as to why these risks are occurring much more often for black women, such as little access to healthcare. It seems that Gilman would have wanted to achieve gender equity with her story, but it is also important to prioritize racial equity in a situation like this. With the ending of the story and how the narrator ended up going insane, Gilman was trying to show the harm that would occur when medical professionals refuse to acknowledge women and their cries for help and why it is important to care for mothers and pregnant women. She knew she had the responsibility to do what’s right and express how unjust society was back then. Despite having to suffer through her mental illness, Gilman never gave up on trying to make a change whether it was for just one woman or all of them. Although we have come a long way from where we once were, we still have a long way to go before we can say that all women are regarded equally.    Eichelberger, Kacey Y., et al. â€Å"Black Lives Matter: Claiming a Space for Evidence- Based Outrage in Obstetrics and Gynecology.† American Journal Of Public Health, vol. 106, no. 10, Oct. 2016, pp. 1771–1772.

Global warming Research Paper Example | Topics and Well Written Essays - 3250 words

Global warming - Research Paper Example Plants captured atmospheric carbon and converted it into sometime useful for the plant and life. These processes continued for thousands of centuries and the atmosphere became pleasant. However, due to the impact of the natural disasters like earth quakes, floods, etc, the plants, tress and organisms died on a massive scale and buried under the layers of sand. The immense pressure and temperature under the layer of sedimentation converted the organisms back to the carbon compounds. There organic compounds with greater ratio of carbon is present under the crust in the form of coal, oil and natural gas. These organic compounds are often referred as fossil fuel resources. When human race discovered that there is an immense amount of energy trapped in the coal, oil and natural gas, they tried to extract the energy out without acknowledging what will be byproduct of the reaction and how byproduct will affect the earth’s atmosphere and human life. The use of fossil fuel resources increased as the hunger for energy increased. No one has the idea hat the burning process is doing to the environment. In the 19th century, the demand for energy increased significantly due to the massive industrialization. Industrial goods were considered more reliable. Trains as the medium of transportation were introduced. Trains reduced the time period of the journeys. Steam trains utilized massive amount of coal to generate mechanical power fro the train. The use of coal in various other sectors also increased. Some people argued that coal energy is not good to the health but coal was the prior source of energy and no one argued to restrict the use of technology no matter what are the side effects of the energy. With the invention of internal combustion engines, fossil fuel based oil resources were used to power the internal combustion engines. Cars, motorcycles, trucks, busses, etc are fitted with internal combustion engines. Many industrialists came up with newer vehicle designs

The Berlin Conference of 1884 and Africa Research Paper

The Berlin Conference of 1884 and Africa - Research Paper Example The continent was relatively isolated from the rest of the world especially the western countries but historians have recorded early trade in Africa. Trans-Saharan trade is one of the earliest recorded commerce, carried out in Africa between eighth and 16th century (Wright, 2007). According to Wright (2007), Trans -Saharan trade was concentrated in the northern Africa and it involved countries around the Mediterranean Sea and West Africa. The trade route crossed the Saharan desert and the caravans travelled for long distances to obtain goods in various regions covered in the larger frontier. The Arabs dominated the trade and it mainly involved precious metals such as gold that was mined in West African region, ivory, salt and agricultural products. In addition, slave trade was an important component of Trans- Saharan trade, and African servants were transported to the north to work as soldiers and domestic workers (Wright, 2007 pp76-81). Conditions Leading to the Berlin Conference Th e rich gold deposits and success of the Trans-Saharan trade attracted the attention of Europeans and in the 15th century, Portuguese traders opened new trade routes along the West African coast that had rich gold deposits (Wright, 2007 p 137). ... In the mid 1870, Henry Morton successfully completed the Congo River basin expedition that had remained the last unchartered frontier in Africa (Emerson, 1979). Henry Morton was later appointed by King Leopold II of Belgium as an envoy to Congo that eventually became Congo Free State, a Belgian colony (Emerson, 1979 p69). In central Africa, France moved to the western part of the Congo basin and established Brazzaville in 1881. Great Britain conquered and occupied the Ottoman Empire in Egypt that ruled Sudan and the Somaliland. Germany declared territorial ownership of Namibia, Cameroon, and Togo while Italy claimed Eritrea in the horn of Africa in 1882 (Koponen, 1993 p124). The scramble for more African colonies generated intense competition among the European powers leading to violent conflicts and the need to have a more organized criterion for partitioning Africa became apparent. Germany had become an influential European power and other countries, including France and Britain we re aggressively seeking new colonies to assert their power in Europe. In view of the emerging power changes in Europe, Germany was determined to maintain its leading influence in Europe. Therefore, it was important to formulate a reasonable formula of partitioning African continent among the competing European powers to avoid the risk of conflict that would threaten Germany influence in Europe and the globe (Koponen, 1993, pp 129-133). The Berlin Conference At the request of Portugal, the German chancellor Otto von Bismarck invited leaders of fourteen European countries with territorial interests in Africa, and the United States for a conference in Berlin in 1884 (Collins,

The Types And Techniques Of Steganography Computer Science Essay

The Types And Techniques Of Steganography Computer Science Essay This document focus on an unfamiliar field of study in IT sector i.e. Steganography. This document covers various concepts in Steganography, A brief history of Steganography and introducing few types of techniques available today in Steganography. It also covers other topics like security in Steganography, mobile messaging, MMS Steganography related information. This document closes with a summery and proper solution . The initial footages of Steganography were by the Greek historian Herodotus in hischronicles known as Histories and date back to around 440 BC. Herodotus recorded two stories of Steganographic techniques during this time in Greece. The first stated that King Darius of Susa shaved the head of one of his prisoners and wrote a secret message on his scalp. When the prisoners hair grew back, he was sent to the Kings son in law Aristogoras in Miletus undetected. The second story also came from Herodotus, which claims that a soldier named Demeratus needed to send a message to Sparta that Xerxes intended to invade Greece. Back then, the writing medium was text written on wax-covered tablets. Demeratus removed the wax from the tablet, wrote the secret message on the underlying wood, recovered the tablet with wax to make it appear as a blank tablet and finally sent the document without being detected. Romans used invisible inks, which were based on natural substances such as fruit juices and m ilk. This was accomplished by heating the hidden text, thus revealing its contents. Invisible inks have become much more advanced and are still in limited use today. During the 15th and 16th centuries, many writers including Johannes Trithemius (author of Steganographia) and Gaspari Schotti (author or Steganographica) wrote on Steganagraphic techniques such as coding techniques for text, invisible inks, and incorporating hidden messages in music. Between 1883 and 1907, further development can be attributed to the publications of Auguste Kerckhoff (author of Cryptographic Militaire) and Charles Briquet (author of Les Filigranes). These books were mostly about Cryptography, but both can be attributed to the foundation of some Steganographic systems and more significantly to watermarking techniques. During the times of WWI (World War 1) and WWII (World War 11), significant advances in Steganography took place. Concepts such as null ciphers (taking the 3rd letter from each word in a harmless message to create a hidden message, etc), image substitution and microdot (taking data such as pictures and reducing it to the size of a large period on a piece of paper) were introduced and embraced as great steganographic techniques. In the recent digital world of today, namely 1992 to present, Steganography is being used all over the world on computer systems. Many tools and technologies have been created that take advantage of old steganographic techniques such as null ciphers, coding in images, audio, video and microdot. With the research this topic is now getting a lot of great applications for Steganography in the near future. HOW STEGANOGRAPHY WORKS Steganography replaces unneeded or unused bits in regular computer files (Graphics, sound, text) with bits of different and invisible information. Hidden information can be any other regular computer file or encrypted data. Steganography differs from cryptography in a way that it masks the existence of the message where cryptography works to mask the content of the message. Steganography sometimes used in conjunction with encryption. An encrypted file may still hide information using steganography, so even if the encrypted file is deciphered,the hidden information is not seen. . TYPES OF STEGANOGRAPHY There are different ways to hide the message in another, well known are Least Significant bytes and Injection. When a file or an image is created there are few bytes in the file or image which are not necessary or least important. These type of bytes can be replaced with a message without damaging or replacing the original message, by which the secrete message is hidden in the file or image. Another way is a message can be directly injected into a file or image. But in this way the size of the file would be increasing accordingly depending on the secrete message STEGANOGRAPHY IN IMAGE Digital images are the most widely used cover objects for steganography. Due to the availability of various file formats for various applications the algorithm used for these formats differs accordingly. An image is collection of bytes (know as pixels for images) containing different light intensities in different areas of the image. When dealing with digital images for use with Steganography, 8-bit and 24-bit per pixel image files are typical. Both have advantages and disadvantages 8-bit images are a great format to use because of their relatively small size. The drawback is that only 256 possible colors can be used which can be a potential problem during encoding. Usually a gray scale color palette is used when dealing with 8-bit images such as (.GIF) because its gradual change in color would be harder to detect after the image has been encoded with the secret message. 24-bit images offer much more flexibility when used for Steganography. The large numbers of colors (over 16 million) that can be used go well beyond the human visual system (HVS), which makes it very hard to detect once a secret message, has been encoded. Large amount of data can be encoded in to 24-bit images as it is compared to 8-bit images. The drawback of 24-bit digital images is their size which is very high and this makes them suspicious our internet due to their heavy size when compared to 8-bit images. Depending on the type of message and type of the image different algorithms are used. Few types in Steganography in Images: Least significant bit insertion Masking and filtering Redundant Pattern Encoding Encrypt and Scatter Algorithms and transformations Least significant bit insertion Least Significant Bit (LSB) insertion is most widely known algorithm for image steganography ,it involves the modification of LSB layer of image. In this technique,the message is stored in the LSB of the pixels which could be considered as random noise.Thus, altering them does not have any obvious effect to the image. Masking and filtering Masking and filtering techniques work better with 24 bit and grey scale images. They hide info in a way similar to watermarks on actual paper and are sometimes used as digital watermarks. Masking the images changes the images. To ensure that changes cannot be detected make the changes in multiple small proportions. Compared to LSB masking is more robust and masked images passes cropping, compression and some image processing. Masking techniques embed information in significant areas so that the hidden message is more integral to the cover image than just hiding it in the noise level. This makes it more suitable than LSB with, for instance, lossy JPEG images. Redundant Pattern Encoding Redundant pattern encoding is to some extent similar to spread spectrum technique. In this technique, the message is scattered through out the image based on algorithm. This technique makes the image ineffective for cropping and rotation. Multiple smaller images with redundancy increase the chance of recovering even when the stegano-image is manipulated. Encrypt and Scatter Encrypt and Scatter techniques hides the message as white noise and White Noise Storm is an example which uses employs spread spectrum and frequency hopping. Previous window size and data channel are used to generate a random number.And with in this random number ,on all the eight channels message is scattered through out the message.Each channel rotates,swaps and interlaces with every other channel. Single channel represents one bit and as a result there are many unaffected bits in each channel. In this technique it is very complex to draw out the actual message from stegano-image. This technique is more secure compared to LSB as it needs both algorithm and key to decode the bit message from stegano-image. Some users prefer this methos for its security as it needs both algorithm and key despite the stegano image. This method like LSB lets image degradation in terms of image processing, and compression. Algorithms and transformations LSB modification technique for images does hold good if any kind of compression is done on the resultant stego-image e.g. JPEG, GIF. JPEG images use the discrete cosine transform to achieve compression. DCT is a lossy compression transform because the cosine values cannot be calculated exactly, and repeated calculations using limited precision numbers introduce rounding errors into the final result. Variances between original data values and restored data values depend on the method used to calculate DCT STEGANOGRAPHY IN AUDIO Implanting secrete message into an audio is the most challenging technique in Steganography. This is because the human auditory system (HAS) has such a vibrant range that it can listen over. To put this in perspective, the (HAS) recognize over a range of power greater than one million to one and a range of frequencies greater than one thousand to one making it extremely hard to add or remove data from the original data structure. The only weakness in the (HAS) comes at trying to differentiate sounds (loud sounds drown out quiet sounds) and this is what must be exploited to encode secret messages in audio without being detected. Below are the lists of methods which are commonly used for audio Steganography. LSB coding Parity coding Phase coding Spread spectrum Echo hiding LSB coding Using the least-significant bit is possible for audio, as modifications usually would not create recognizable changes to the sounds. Another method takes advantage of human limitations. It is possible to encode messages using frequencies that are indistinct to the human ear. Using frequencies above 20.000Hz, messages can be hidden inside sound files and can not be detected by human checks. Parity coding Instead of breaking a signal down into individual samples, the parity coding method breaks a signal down into separate regions of samples and encodes each bit from the secret message in a sample regions parity bit. If the parity bit of a selected region does not match the secret bit to be encoded, the process flips the LSB of one of the samples in the region. Thus, the sender has more of a choice in encoding the secret bit, and the signal can be changed in a more unobtrusive fashion. Phase coding Phase coding attends to the disadvantages of the noise inducing methods of audio Steganography. Phase coding uses the fact that the phase components of sound are not as audible to the human ear as noise is. Rather than introducing perturbations, this technique encodes the message bits as phase shifts in the phase spectrum of a digital signal, attaining an indistinct encoding in terms of signal-to-perceived noise ratio. Spread spectrum In the context of audio Steganography, the basic spread spectrum (SS) method attempts to spread secret information across the audio signals frequency spectrum as much as possible. This is comparable to a system using an implementation of the LSB coding that randomly spreads the message bits over the entire audio file. However, unlike LSB coding, the SS method spreads the secret message over the sound files frequency spectrum, using a code that is independent of the actual signal. As a result, the final signal occupies a bandwidth in excess of what is actually required for broadcast. Echo hiding In echo hiding, information is implanted in a sound file by introducing an echo into the separate signal. Like the spread spectrum method, it too provides advantages in that it allows for a high data transmission rate and provides superior strength when compared to the noise inducing methods. If only one echo was produced from the original signal, only one bit of information could be encoded. Therefore, the original signal is broken down into blocks before the encoding process begins. Once the encoding process is completed, the blocks are concatenated back together to create the final signal. STEGANOGRAPHY IN VIDEO In video steganography, a video file would be embedded with supplementary data to hide secret messages. In the process, an intermediate signal which is a function of hidden message data and data of content signal would be generated. Content data (video file) is then combined with this intermediate signal to result encoding. The supplementary data can include copy control data which can be brains by consumer electronic device and used to disable copying. The intermediate signal may also contain a pseudo arbitrary key data so as to hide encoding and decode needs corresponding key to extract hidden information from encoded content. In some implementations regulation data is embedded in the content signal with auxiliary data. This regulation data consists of known properties enabling its identification in the embedded content signal. This encoding is robust against scaling, resampling and other forms of content degradation, so that the supplementary data can be detected from the content which might have been degraded. There are different approaches for video steganography apart from the above mentioned. Most widely known are listed and discussed below. Least Significant Bit Insertion This is the most simple and popular approach for all types of steganography. In this method the digital video file is considered as separate frames and changes the displayed image of each video frame. LSB of 1 byte in the image is used to store the secret information. Effecting changes are too small to be recognized by human eye. This method enhances the capacity of the hidden message but compromises the security requirements such as data integrity. Real time video steganography This kind of steganography involves hiding information on the output image on the device. This method considers each frame shown at any moment irrespective of whether it is image; text .The image is then divided into blocks. If pixel colors of the blocks are similar then changes color characteristics of number of these pixels to some extent. By labeling each frame with a sequence number it would even be easy to identify missing parts of information. To extract the information, the displayed image should be recorded first and relevant program is used then. STEGANOGRAPHY IN DOCUMENT Steganography in documents just focuses on altering some of its characteristics. They can either be characteristics of text or even text formatting. Below are few ways listed and discussed to implement the same. Since everyone can read, encoding text in neutral sentences is doubtfully effective. But taking the first letter of each word of the previous sentence, one can see that it is possible and not very difficult. Hiding information in plain text can be done in many different ways. One way is by simple adding white space and tabs to the ends of the lines of the document .The last technique was successfully used in practice and even after a text has been printed and copied on paper for ten times, the secret message could still be retrieved. Another possible way of storing a secret inside a text is using a publicly available cover source, a book or a newspaper, and using a code which consists for example of a combination of a page number, a line number and a character number. This way, no information stored inside the cover source leads to the hidden message. Discovering it depends exclusively on gaining knowledge of the secret key. Setting background color and font color is one of the mainly used staganographic approach. This method is focused for Microsoft word documents. Choose predefined colors and set font and background colors of invisible characters such as space, tab or the carriage return characters. R,G,B values are 8 bits means we have allowed range of 0 to 255.Most of the viewers would not feel interested about color values of these invisible characters hence 3 bytes of information is easily hidden in each occurrence of space,tab or carriage return.This approach needs no extra information to hide required bits. SECURITY IN STEGANOGRAPHY PURE KEY STEGANOGRAPHY Pure Steganography is a Steganography system that doesnt require prior exchange of some secret information before sending message; therefore, no information is required to start the communication process: the security of the system thus depends entirely on its secrecy .The pure Steganography can be defined as the quadruple (C, M, D, and E) where: C: the set of possible covers. M: the set of secret massage with |C| à ¢Ã¢â‚¬ °Ã‚ ¥ |M|. E: CÃÆ'-Mà ¢Ã¢â‚¬  Ã¢â‚¬â„¢C the embedding function. D: Cà ¢Ã¢â‚¬  Ã¢â‚¬â„¢M of the extraction function with the property that D (E(c,m))=m for all m à Ã¢â‚¬Å¾ M and c à Ã¢â‚¬Å¾ C. Cover (C) Message (M) Embedding (E) Extracting (D) Strgo-Object Message(M) In most applications, pure Steganography is preferred, since no stego-key must be shared between the communication partners, although a pure Steganography protocols dont provide any security if an attacker knows the embedding method PRIVATE KEY STEGANOGRAPHY A Private Key Steganography system is similar to a symmetric cipher, where the sender chooses a cover and embeds the secret message into the cover using a secret key. If the Private Key used in the embedding process is known to the receiver, he can reverse the process and extract the secret message. Anyone who doesnt know the Private Key should not be able to obtain evidence of the encoded information. The Private Key Steganography can be defined as the quintuple (C, M, K, DK, and EK) where: C: the set of possible covers. M: the set of secret message. K: the set of secret keys. Ek: CÃÆ'-MÃÆ'-Kà ¢Ã¢â‚¬  Ã¢â‚¬â„¢C With the property that DK (EK(c,m,k),k)=m for all m à Ã¢â‚¬Å¾ M, c à Ã¢â‚¬Å¾ C and k à Ã¢â‚¬Å¾ K KEY KEY Strgo-Object Cover (C) Embedding (E) Message (M) Extracting (D) Message (M) PUBLIC KEY STEGANOGRAPHY Public key Steganography does not depend on the swapping of a private key. It necessitates two keys, one of them private (secret) and the other public: the public key is stored in a public database, whereas the public key is used in the embedding process. The Private Key is used to reconstruct the secret message One way to build a public key Steganography system is to use a public key crypto system. The sender and the receiver can exchange public keys of some public key cryptography algorithm before imprisonment. Public key Steganography utilizes the fact that the decoding function in a Steganography system can be applied to any cover, whether or not it already contains a secret message. The public key Steganography relies on the fact that encrypted information is random enough to hide in plain sight. The sender encrypts the information with the receivers public key to obtain a random-looking massage and embeds it in a channel known to the receiver, thereby replacing some of the natu ral arbitrariness with which every communication process is accompanied. Assume that both the cryptographic algorithms and the embedding functions are publicly known. The receiver who cannot decide a priori if secret information is transmitted in a specific cover suspect the arrival of message and simply try to extract and decrypt it using his private key. If the cover actually contained information, the decryption information is the senders message OTHER TYPES MOBILE MESSAGING STEGANOGRAPHY Mobile Messaging Service enables mobile users to send and receive messages containing image, audio and video. These messages are exchanged ultimately through a component known as Mobile Switching Center. MMS messages have several benefits like communicating even when the server is busy, exchanging messages while making calls, sending offline messages. They also provide services like eCommerce. As there is possibility of disclosure of confidential and personal information between various systems, information security has got immense importance. MMS Steganography provides confidentiality and integrity with subtle unremovability.Users can profit from concealed channels in order to send and receive hidden messages and keys. Multimedia objects may contain hidden information embedded to them using steganography techniques. The steganography technique used must satisfy following: Reliability of secreted information after it has been embedded inside the content should be correct. Content object should remain intact or almost unchanged to the human eyes. There can be mainly two types of steganography techniques possible for MMS objects. Fragile steganography comprises of implanting information into a file which is destroyed if the file is modified. Video Technique: Works over video files. Combinations of sound and image techniques are used to implement this as whole. The scope of adding lots of data is much greater. Sound Technique: Works over audio files like Mp3 files. Encode data as binary to sound like noise and can be identified by receiver with correct key. Data being added is in narrow bandwidth compared to the medium. Robust techniques aim to embed information into a file which cannot easily be destroyed. Image Hiding: Works over images. Lease Significant Bit Least significant bits of each pixel in one image are used to hide the most significant bits of another. Simple and easy way of information hiding. Direct Cosine Transform Transformed DCT coefficients would be altered. Image would be made robust by scattering the hiding information evenly. Wavelet Transform Dividing whole image into small wavelets and then hide the information. Coefficients of wavelets are altered with tolerable noise. Text Technique: Works over documents.Just by changing some of the characteristics of the content information can be embedded. Alterations would not be visible to user. As MMS Steganography becomes more widely used now there must be a clear definition of robustness. This definition helps to prevent detection and removal of embedded data. Below are the few properties a good technique should hold: Quality of media should not perceptibly degrade after embedding secret data. Secret data should be imperceptible with out secret knowledge, typically the key. If several data are there, they should not hamper with each other. Secret data should survive which dont degrade the perceived quality of work. MMS STEGANOGRAPHY RELATED WORK As MMS carries multi formatted data such as Text, Audio, Video and images, it has got more chances of sending secret messages and can implement various methodologies in order to keep the message safe and secret. Currently this study is all about Text and Video based Steganography. An MMS capable mobile with inbuilt cameras and customized applications has high importance in terms of steganography creation and extraction Capacity Efficiency Processing time Resource time consumption Advantage Text technique Less More Less Less Easy and simple to implement Video technique More More More More Holds lot of information compared to text technique Table -1- comparison between Text and Video steganography Techniques PROPER SOLUTION MMS Messages can hold any of video, audio, image and text encapsulated with in Synchronized Multimedia Integration Language (SMIL) . The recommended steganography deals with three major parts of MMS which can provide us with maximum capacity possible and not compromising main aim which is total security. The most important issues in steganography are secrecy, payload, robustness and speed. Below steps describes proposed steganography working model: First part of the process hides stegno key in SMIL using white space algorithm. Then Least Significant Bit algorithm is used to hide the secret message in video. Rest of the information would be hidden inside text of the MMS using abbreviation algorithm. Ratio of information hiding in video part to text part is 6:1 hence I bit stored in text corresponds to 6 bits stored in 3gp video. High security can be granted with reasonable processing speed and without affecting the performance of mobile. 2.10 CHAPTER SUMMERY This document is all about available Steganography techniques and methodologies. It has listed down the various methodologies and their uses. Along with these, it has also included about the MMS Steganography importance and ways to do that.

The Beef with TV Essay -- essays research papers

Television: Our Nations Drug of Choice   Ã‚  Ã‚  Ã‚  Ã‚  Television is our era’s escape from what we now consider a chaotic struggle of life. I think we as a people feel life can be solved in an hour long Monday night special and that exact attitude is our society’s problem today. Frankly we are a group of cowards who do not take the bull by the horns; rather we retreat to routine episode line up that we can supposedly relate to. Ladies and gentlemen we need to break free like Plato’s slave in the myth of the cave, by realizing that life is not â€Å"Ragged, loose and something hard to cope with† (Dove) but rather a beautiful journey far off into the beyond.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Over ninety-eight percent of homes in America have television, while only ninety percent have telephones. Most often the programs the viewer receives are quite harmful to them physically, mentally, developmentally, and even financially.†(Paul) The theory that ‘The Tube’ is a bad thing should be no longer be pondered, it is a very bad thing. People who sit in front of the T.V. religiously often feel that they can quit at whatever time they want to, and pick up where they left off in their daily activities. Most often, nevertheless, people grow to be very flaccid about their lives; the individual sees their once everyday behavior less attractive and more complex. The scariest part of this bad habit we as a nation develop from watching television is its uncanny resemblance to heroine u...
