Dynamic watermarking algorithm based on chaotic optimization

In order to improve the stealth and robustness of software watermarking, the chaos theory was applied to the software watermarking algorithm, mainly by optimizing and improving the dynamic graph CT algorithm based on chaos-replacement and chaos-encryption. Chaos-based dynamic watermarking algorithm (CBDW) was achieved under the VC60 C++ environment, and some analyses were conducted. Experimental results demonstrate that, while maintaining its advantage of high data rate, the proposed approach is effective in enhancing stealth and robustness of the original watermark.
