Abstract : Steganography and Visual Cryptography are two areas in which many studies and intensive research have been carried out. Even though the basic idea of both areas in hiding information are similar,steganography and visual cryptography makes use of different methodologies in order to protect their data.In this paper, a method is proposed for combining steganography and visual cryptography. In the proposed method, secret data is embedded using Matrix embedding technique using Hamming codes and shares are generated from this stego image using Random Grids method. The main advantage of Random grids method is there is no pixel expansion; hence embedded secret data can be fully recovered on stacking the shares. This idea of combining steganography and visual cryptography can present a great area for research especially in the world of forensics. © 2011 Springer-Verlag.
