Digital Image Steganography
Digital Stegonography is used to hide a message, normally in a larger message, which is unknown to others. Stegonography attempts to hide the existence of the message but does not make the information unintelligible. Digital Stegonography has a “carrier” for the message and key. The “carrier” can be a digital image, TCIP/IP or a MP3. A code can be used to decode the hidden message.
Digital Stegonographic focuses on the data that is replicated, however, these hidden messages do not cause noticeable changes. This is used in graphic files, which contain a number of things. HTML, video, sound files and text files are all examples. The most widely known “stego-image” is the image files. Digital Stegonographic can also be used for people being censored. This information can be found in military, government and even law enforcement.
