In this work a new data hiding algorithm for binary images is used. In this algorithm the pixels which can be flipped without introducing noticeable artifacts are identified at first by using some rules that examine the neighbors of the central pixels in each non-uniform block and then this central pixel only is changed in the block which matches these rules and this property allows easy detection of the embedded data without referring to the original   image. Experiments show different results for different binary images. The program is written  in MATLAB (6.5).
