Reversible Data Hiding Based on Geometric Structure of Pixel Groups

[[abstract]]Many reversible data hiding schemes have been developed in recent decades. Traditional schemes typically must deal with the problem of overflow and underflow, or transmission of hiding parameters. The new reversible data hiding scheme proposed in this paper is based on a combination of pixel groups’ geometric structure and secret sharing mechanism. Experimental results confirm that the proposed scheme not only achieves the goal of hiding information without memorization of location map or any other parameter, but also generates very high quality stego-images with very large capacity of secret information embedded
