At present, while there are many conveniences in people's lives, lots of problem have also appeared with the development of information technology. In order to solve the problem of increasingly serious intellectual property disputes, the research on digital watermarking is particularly important. Due to the digital watermarking for real-time requirement is not high. We improve the decoding algorithm in response to the oscillating iterative phenomenon that occurs during the LDPC code decoding algorithm; and the improved decoding algorithm has been introduced into the digital watermark technology. Finally, the simulation is realized through MATLAB, the results show that the improved LDPC code decoding algorithm significantly improves the robustness of digital watermarking obviously.
