摘要：In this paper, a new Steganography technique is presented, implemented and analyzed. The proposed method hides the secret message based on searching about the identical bits between the secret messages and image pixels values. The proposed method is compared with the LSB benchmarking method. It is implemented to hide the secret message "I will come to see you on the first of June" on two Bmp images, with size (24 x 502 x 333) and (24 x 646 x 165) respectively. The results of the proposed and LSB hiding methods are discussed and analysed based on the ratio between the number of the identical and the non identical bits between the pixel colour values and the secret message values. As there are many techniques to perform steganography on electronic media, most notably audio and image files. The outcome of this paper is to generate a cross platform that can effectively hide a message inside a digital image file. An image is the combination of several pixels and each pixel has three colour numbers and an image consist of millions of numbers. So the change in few colour numbers resulting the picture which would probably look a lot likes the original image. In this paper we are presenting the technique which works by changing a few pixel color value. we will use selected pixel value to represent characters instead of a color value. Obviously the resulting image will still look mostly like the original except that a few points seem little out of place if we look very closely.
