A New Method in Image Steganography with Improved Image Quality

"Steganography” is a Greek origin word which means “hidden writing”. Steganography word is classified into two parts: Steganos which means “secret or covered” (where you want to hide the secret messages) and the graphic which means “writing” (text). 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 analyzed based on the ratio between the number of the identical and the non identical bits between the pixel color values and the secret message values. The proposed method is efficient, simple and fast it robust to attack and improve the image quality, hence it obtained an accuracy ratio of 83%.
