摘要
根据PE文件资源节结构和资源信息查找特点,提出了一种新的保护软件版权的水印算法。新算法引入了水印认证中心,利用大数分解难题生成具有法律效力的水印信息,用水印控制软件资源节结构图中节点的存放顺序,将水印信息隐藏于重排的资源结构图中。水印提取完全实现了盲检测。经分析,该算法能有效抵抗多种常见的攻击,具有较强的不可感知性和鲁棒性。
A novel watermark algorithm for copyright protection of software based on PE file resources section format is proposed. The new algorithm introduced watermark authentication center, produced watermark information using technology of large-number-difficult- decomposition, control the node storing order of software resources section structure according to the watermark and bided watermark in rearrangement resources structure. The watermark detection is completely blind. The theoretical analysis and experimental results indicated that the novel algorithm is very imperceptible and immune to most known attacks.
