A new approach of AScienceDaily (May 9, 2011) to hide the data within the program files on a computer could make it nearly impossible to detect hidden documents, according to a report International Journal of Internet technology and secured.
Steganography is a form of security through obscurity information hidden inside the medium. An artist might paint a message encoded into a portrait, for instance, or author to embed lyrics in the text. Traditional paper watermark is an example of steganography is in action. At first glance, it appears that there is nothing unusual, but the recipient aware of the presence of hidden message can be extracted easily. In computer science, more than the art of steganography.
These target to hide information from prying eyes to embed data in many different file types that are ostensibly (mp3) of music, photos (jpeg), video (mpeg4) or word processing documents. Unfortunately, there is no limit to the amount of hidden data can be embedded in such files without this information becomes clear something is hidden because the file size increases beyond what can be expected for shared music or video file, for example. A music file to mp3 format in five minutes as the sampling rate of 128 kilobits per second, for example, is expected to be 5 megabytes in size. Much bigger aroused suspicions about the true nature of the file, a software mp3-tags in the open, something is wrong with the content of the file. This can be said for almost any other file types.
However, one set of files and their size, they are usually quite difficult to examine in detail that they provide compile computer code are the executable files or exe. These files tend to contain a lot of what might be described as "spam", as well as internal and programmer notes, redundant code snippets, some senses infuriatingly inflate code. All this adds up large file sizes and random fact for the .exe files. As such, it may be possible to embed and hiding large amounts of data in an encrypted file without disrupting the ability of the executed file, or run a program but ???????? without anyone discovering the file exe has a dual function.
Computer scientists Rajesh Kumar Tiwari of GLNA at Mathura, g., Sahoo of birla Institute of technology, Mesra, Ranchi, India, developed this algorithm for embedding hidden data in the session. They provide information International Journal of Internet technology and secured transactions. The algorithm built into the program with a graphical user interface will take the conventional exe file as input hidden data, merge the two producing sustainable exe file with the hidden content. The technology can be used on smart phones, tablet PCs, portable media players or any other information which a user may want to hide data.
