Cyclic Combination Method For Digital Image Steganography With Uniform Distribution Of Message

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