Comparison of LSB and MSB Based Image Steganography

Steganography is an art of communication that hides the secret (i.e. message, information or communication in any form) data over a public channel. Hiding the occurrence of communication can be done by superimpose a secret message into cover message (i.e. an stego image) which the sender and the receiver can suspect only but third party cannot suspect the secret message. Therefore, in order to protect the secret messages from the third party there are many algorithms to hide the secret message. The algorithms are very complex i.e., number of steps are too much in the algorithm previously proposed but the value of PSNR is still less by that method.
