【摘要】 为增强软件水印的鲁棒性,将图像"多水印"思想引入到软件中,并给出软件多水印定义,分析联合方式,给出模型及优化方法。在此基础上,提出一种基于多水印的软件版权保护模型,并对原有的算法进行改进,解决有意义软件水印的预处理问题、指纹的动态混淆嵌入及交互防篡改检测问题,提高软件水印的鲁棒性。实验表明,该模型在防止静态分析、动态跟踪、反逆向工程以及保护水印和软件的完整性方面具有较好的性能。更多还原

【Abstract】 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 optimization method.On the basis,the multi-watermarking based on model of software copyright protection was proposed,and the original algorithm was improved,such as the meaningful pre-processing 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 software integrity of the watermark has good performance.更多还原
