Abstract
To reduce the size of hash code and enhance the security of wave atoms based image authentication system, a Slepian-Wolf (SW) code is employed to encode the hash code. With the help of a legitimately modified image, the comprebed hash code could be correctly decoded while the decoding will be failed with the help of a maliciously attacked image. Therefore, the SW code could provide a desired robustneb to image authentication. Simulation results indicate that the proposed scheme provides a better performance with leb hash code than the existed approach. Moreover, the proposed scheme outperforms the random projection based approach in terms of authentication accuracy and data size.
