利用数字水印技术验证文本信息的篡改

An Applicable Watermark Technique to The Confidential Job

数字水印技术是信息隐藏技术的一个重要分支,论文介绍一种易损水印技术,它采用混沌算法生成水印序列,将其嵌入到文本载体之中。算法能够有效的验证文本信息的正确性和完整性,从而可以用于军队机要工作中保证传输的机密信息的安全性。

Watermark technique is one of important branches of Information-hiding. Paper discusses a method which make use of Chaos algorithm to generate the watermark serial, then embed it into the carrier-text. The algorithm is able to validate whether the text is correct and integrated, so that it can be used into the confidential job to guarantee the security of the secret information accepted.
