摘要：

To solve the problem that most digital watermarking algorithms have the poor performance on the application and universality, a novel watermarking technology based on the theory of quantum error correction is proposed. According to the principles of quantum coherence and mechanical superposition, the watermark is embedded into the carrier in the format of quantum error codes, and it is extracted by the approach of quantum error correcting. It is introduced that the embedding and extraction of the quantum digital watermarking algorithm in this paper. Further, the text is examined as a carrier instance for this algorithm. The sensory test results indicate that the anti-attack capability of the algorithm is 4 times of the text-formatted watermarking. On attack tests, the error-coding rate of the quantum watermarking decreased an average of 18.06 percent compared with others. The experiment shows that this algorithm has a better performance on universality and robustness.
