Sharing software watermarking scheme based on chaotic optimization.

In order to solve the poor robustness of software watermarking and the low execution efficiency of watermarking sharing algorithm, this paper proposed a sharing software watermarking scheme based on chaotic optimization. The scheme took advantage of chaos system, matrix partition and chaotic scrambling the watermarking information to form sharing watermarking. When watermarking was embedded, using DPPCT topology graph encode the sharing watermarking, then putting the hash value of the watermarking information into the info field of each DPPCT. After the watermarking embedded, using chaotic encryption to protect all code and prevent reverse engineering and other methods to attack the software watermarking. Theoretical analysis and experimental results show that the scheme can effectively resist various semantics preserving transformation attacks, decrease the program load and improve robustness and execution efficiency of the watermarking.
