| 摘 要： | 提出一种以存储为中心的交易和认证模型(SCTAM)及其水印协议,将信息集中存储在交易中心(TC),TC自主处理任务不受外部干预,保障了信息的安全和一致性。User不直接和Owner交互,而是与TC交互购买产品。Judge仲裁过程不需Owner和User参与,实现了公平性。不同的水印技术分别用于Owner和User的水印的嵌入和提取,保障了水印的安全。SCTAM能够解决迄今发现的所有水印协议相关的问题,并简化了水印协议的设计。

The user does not interact with the owner in transaction; the judge can make decision without the aids from the owner and the user, which is fairer. Different watermark techniques are used to embed and extract watermarks for the owner and for the user to ensure the security of th... |
