摘要：In this paper, a new image steganography technique for embedding messages into Gray Level Images is proposed. This new technique distributes the message uniformly throughout the image. The image is divided into blocks of equal sizes and the message is then embedded into the central pixel of the block using cyclic combination of 6th, 7th & 8th bit. The blocks of the image are chosen randomly using the Pseudo Random Generator seeded with a secret key. In proposed method, cyclic combination of last three bits of pixel value provide 100% chances of message insertion at the pixel value and division of image into blocks distribute the message uniformly into the image. This method also provides minimum degradation in image quality that cannot be perceived by human eye.
