Abstract :
A reversible watermarking algorithm is presented, which achieves content authentication and perfect restoration of the original image during extraction. The proposed algorithm is based on patchwork and chaotic encryption. The patchwork algorithm is used to generate zero-bit watermark for content authentication. The chaotic sequence is used to encrypt the general LSBs(Least Significant Bits) of image pixels. The results show this scheme is reversible and safe.
