Steganographic secure data communication

Steganography gained importance in the past few years due to the increasing need for providing secrecy in an open environment like the internet. Steganography attempts to hide the very existence of the message and make communication undetectable. This paper is based on the implementation of steganography using LSB algorithm. The Least Significant Bit (LSB) embedding Technique that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden data in the cover file. The proposed system hide secret data into cover image using Two bit and three bit LSB algorithm and decoding using same algorithm.
