Multiple LSB data hiding based on pixel value and MSB value

Steganography is an art of secret data communications. Its main purpose is to hide the occurrence of communication over a public channel. Steganography tends to hide the very existence of the message or communication in any form. Hiding the occurrence of communication can be done by embedding a secret message into an innocent cover medium, such as an image, which no one else other than the sender and the recipient can suspect. There could be some important data that need to be protected during transmission. Therefore, how to protect the secret messages during transmission becomes an important research issue. In this paper authors going to discuss about Multiple LSB (least significant bit) base algorithm and check quality of image. In this paper authors equipment some new techniques of Multiple LSB and discuss some issue related to attacks.
