Concealing of Secret Information Using Steganography

Abstract

The Internet allows for easy extraction of messages over large areas. This is both an advantage and disadvantage since people all over the world can view your image but not your information. Encrypting data has been the most popular approach of protecting information but this protection can be broken with enough computational power. An approach to encrypting data [1] would be to hide it by making this information look like something else. This way people would realize its true content. In particular, if the important data is inside an image then everyone can view it as a picture. This technique is often called data hiding or steganography.
