Data hiding method of binary images based on block masking for key authentication

This paper proposes a new data hiding method for binary images using block masking to distribute keys to two parts and authenticate the right authorized part. The proposed method divides a cover image into a small sub-blocks and design key pairs that decide the position of the embedding bit and determine whether it is possible to embed or not. Also, key pairs are required to extract secret data from the stego-image. The experimental results have a higher capacity and less distortion since almost all data were hidden into edge areas.
