摘要
随着数字作品的网络传播,针对数字信息的版权保护,传统的加密技术具有一定的局限性,而数字水印作为信息隐藏技术的一个分支可望在技术上为数字产品提供有效的保护。提出了一种文本零水印嵌入算法:基于文本字符的Unicode码的奇偶性,不修改载体文本信息,将水印嵌入文本内容中。该算法已通过编程实现,并对其进行了稳健性测试,结果证明此算法隐蔽性强,稳健性较好。由此,该算法应在文本文档的版权保护领域有着广泛的应用前景。
With the spread of digital works on the internet,traditional encryption has some limitations in copyright protection.As a branch of information hiding,digital watermarking is expected to provide an effective protection.Present a text watermark embedding algorithm: the watermark embeds in the text content based on the Unicode's parity,without modifying the carrier.This method was programmed,and tested the robustness.The results show that the method has a good confidentiality and robustness.It can be widely applied in the copyright protection of document.
