摘要
针对静态水印容易遭受攻击导致提取失败的问题,提出了一种基于门限方案的静态软件水印,利用随机数将水印信息分割,在密钥的控制下还原水印信息,增加攻击者的攻击难度,提高水印的鲁棒性.
Aiming at the problem that traditional Static Watermark is likely to be attacked and fail to be extracted, a Static Watermark algorithm based on threshold scheme is proposed, which makes use of random numbers to divide the watermark information, recovers the original watermark information under the control of the Key. The scheme increases the invasive difficulties against invaders, and elevates the robustness of software watermarking.
