Distributed AMELSB Replacement Method For Text Hiding

Abstract

Nowadays, daily communications of all kinds over the Internet have become incredibly popular. However, message transmissions over the Internet still have to face all kinds of security problems. While aim of cryptography is protecting the content of messages, steganography is the technique for hiding additional information in cover data. This paper, proposed method based on Adaptive Minimum Error Least Significant Bit (AMELSBR) but by distributed this error among the gray level components (red(R),green(G),blue(B)) of each pixel, where aim to reduce color variation among pixels when k* message bits embedded in the pixel tacking benefit that the gray level component (R,G,B) for each pixel have the same value , so that R component used to embed the value of k* and both the G and B component used to embed the actual message bits. This method speedup the extraction process so that it is not necessary to reverse the hiding procedure to extract embedded message. Finally, it is not necessary to use control information about the hiding procedure so that the stego cover will be used with full capacity to store the message only.
