Utilizing Image Block Properties to Embed Data in the DCT Coefficients with Minimum MSE

Abstract—Steganography aimed at hiding the presence of communication in a medium that is used to carry secret messages (image, audio, or video). Many steganographic systems can be attacked visually or statistically (steganalysis). In this paper, block based steganography algorithm with minimum MSE is presented, an algorithm that embed data in the least significant bit (LSB) of the discrete cosine transform (DCT) coefficients of JPEG image blocks. This technique exploits the ratio of even to odd coefficients in each image block and embeds data bits in a way that preserves the ratio between even and odd DCT coefficients of each image block. Block Based Steganography (BBS) algorithm offers high capacity with statistically minimal changes compared to current steganographic algorithms. The mean square error of BBS algorithm in the spatial domain is presented.

Index Terms—JPEG hiding, information hiding, steganography, steganalysis,.
