To reduce the size of hash code and enhance the security of wave atom transform (WAT) based image authentication system, a low-density parity-check code based distributed source coding (DSC) is employed to compress the hash code. With the help of a legitimately modified image, the compressed hash value could be correctly decoded while it will fail with the help of a maliciously attacked image. Therefore, the employed DSC provides a desired robustness to image authentication. Simulation results indicate that the proposed scheme provides a better performance with less hash code than existing WAT based image hash without using DSC. Moreover, the proposed scheme outperforms the random projection based approach in terms of authentication accuracy and data size. |
