An intelligent fibonacci approach to image steganography

Steganography is the art of hiding information in a medium. Steganography tends to leave little doubt about the fact that information is being hidden. In this paper an intelligent approach to image steganography is proposed. First, a key is passed using an algorithm such as Diffie-Hellman. This key is used to encrypt the text using an enhanced Caesar Cipher algorithm which provides security and is extremely quick in terms of speed of execution. Next, this key is divided by 10 to get a single digit remainder, say x. x is then used to determine which pixel value is going to be modulated. x is passed as the parameter to a Fibonacci p-code number system. The output obtained say m is taken as the first pixel to be modulated, afterwards all multiples of m such as 2m, 3m etc are modulated. Once all the multiples of m are completed, the last multiple is taken and divided by 10 and the process is repeated till complete data is hidden.
