Jfif steganography

Hides data file into a GIF or JPG file of any size or resolution using a very simple method of appending the message to the file, and then appending a 4 byte little endian number which points to the start of the message. The encryption used is considered "weak" by the author, using another encryption method prior to applying PGE is recommended. When you open an image into a viewer it first loads these headers which are triggered by viewing markers. The first marker is called SOI, or Start of Image, marker. This marker tells the rendering application that it is a JPEG image and it is a standard image that can be read by any platform. This marker is shown as JFIF. Facebook is known to alter and compress uploaded images so they use minimum space and bandwidth when displayed on Facebook pages. The compression process generally disrupts attempts to use Facebook for image steganography. This paper explores a method to minimize the disruption so JPEG images can be used as steganography carriers on Facebook.JFIF is a graphical data format that enables the exchange of compressed JPEG files between computers. The main feature of the format is the use of a marker to indicate parameters that are not used in the JPEG standard, namely, pixel geometry, pixel size and some other parameters. 스테가노그래피(Steganography)의 기원 ...
