摘要
通过分析现有电子文件保护技术的不足,引入了数字标签技术。针对数字标签与电子文件绑定过程中存在的安全问题,提出引入数字水印技术作为传统密码学技术的补充,将数字标签数据作为水印信息均匀地嵌入整个电子文件,使得数字标签数据成为电子文件的内在属性,实现标签数据与电子文件不可剥离的紧密绑定,从而增强了数字标签与电子文件绑定关系的安全性和可靠性。
Based on analysis of the deficiency of the existing e-document protection technology, the digital label technology is introduced. The combination of encryption techniques with digital watermarking is proposed, to protect the binding of digital label and document from its vulnerabilities. By randomly Embedding the label data into the e-document as watermarking, the label data and the e-document are bound tightly, thus enhancing the security and reliability of the bindings.
