Information Hiding in RGB Images Using an Improved Matrix Pattern Approach

In this paper, a novel steganography algorithm based on an improved Matrix Pattern (MP) method is presented. In this process, firstly, an RGB image is divided into the non-overlapping square-sized blocks. Next, 95 dynamicsized unique matrix patterns are automatically generated using the 4th and 5th bit layers of the green layer of each block, which are assigned to 95 English keyboard characters. Then, the blue layer of each block is used for...
