Abstract
In this paper, we present a novel DCSK-based protecting method of watermarks’ information security. We apply chaos sequence to encrypt wateramrks’ information. It makes watermarks’ information more secure than others methods. Then we embedded encrypted sequence into image base on wavelet theory. It make wateramrk’ information secure and secret. As a result, DCSK-based watermarking is more secure in protecting embedded information. Furthermore blind- detection watermarking can be realized. That method possesses research value.
