A new secret image sharing with arithmetic coding

In this paper, we have proposed a new (t, n) secret image sharing scheme. In the proposed method the secret image is pre-processed block wise so that image becomes more suitable for arithmetic coding. The pre-processed information along with compressed bit stream, given by arithmetic coding, are used in secret sharing process. Finally, the generated shares are embedded into the cover images and for data hiding purpose we have adopted LSB based steganography method. This experiment ensures that cover image with same size as secret image is sufficient. Also, the quality of the stego images is more than 43dB which is quite satisfiable.
