Abstract:
Aiming at robustness and efficiency of traditional Dynamic Graph Watermark(DGW), a DGW-AB algorithm based on threshold scheme is proposed, in which the idea of secret sharing to the software watermarking is introduced. Experimental results have shown that the proposed method can make up the weakness of CT algorithm, and prevent invaders from getting the original watermark.

摘要: 针对动态图水印鲁棒性和恢复率较低的问题,提出基于门限方案的动态图水印算法——AB算法。在软件水印中引入密钥共享思想,实验结果证明,该算法能有效弥补CT算法的缺陷,阻止攻击者通过透彻分析运行时的堆栈获取原始水印。
