Steganography is the art of hiding information in ways that prevent its detection. Steganography is usually given as a synonym for cryptography but it is not normally used in that way. It is not intended to replace cryptography but supplement it. Though steganography is an ancient craft, the onset of computer technology has given it new life. Computer-based steganographic techniques introduce changes to digital covers to embed information foreign to the native covers. Such information may be communicated in the form of text, binary files, or provide additional information about the cover and its owner such as digital watermarks or fingerprints. This paper explains a new algorithm which describes how steganography can be combined with cryptography to enhance security in data transfer.
