Abstract

In this paper, we present a novel DCSK-based coding encryption method of DMCP information security. Firstly the DMCP information is got by proprietor or authority as watermarks. Then encrypt key is generated by DMpsilas data. To encrypt watermarkspsila information, we apply the chaos sequence. Then we embed the encrypted sequence into the image based on wavelet approximation zero-tree theory. As a result, DCSK-based watermarking has more secure and secret characteristic in protecting DMCP information. The encrypt key can be computed by itself, though images data may be of some loss.
