| Abstract: | Digital watermark technology is regarded as DNA of digital copyright. Based on analyzing performance and technological characteristics of digital watermark multi-embedding algorithms, embedding conditions were concluded. A new multi-embedding algorithm based on DCT domain was proposed, and it combined two algorithms. At last, simulation was done to the proposed algorithm. The results show it improves the watermark robustness and the ability to attacks greatly. |
