%X To enhance the robustness of software watermarking, the image "multi watermark" was introduced into the software, and gave the definition of multi watermark of the software, analysed the joint, model and optimisation method. On the basis, the multi-watermarking based on model of software copyright protection was proposed, and the original al- gorithm was improved,such as the meaningful preprocessing software watermarking,fingerprint embedded though the dynamic and confusion, the interactive tamper detection improves software watermark robustness. Experiments show that the model in the prevention of static analysis, dynamic tracking, and protection against reverse engineering and soft- ware integrity of the watermark has good performance.
