基于不可见字符的文本水印设计
Text watermarking design based on invisible characters
摘要
Abstract
In order to embed watermarks into text as well as to protect the content against tampering,a text watermarking method based on invisible Unicode characters is proposed.Technically,this method is independent of text layout and style and can be applied to non-formatted text watermarking.Consequently,copyright information can be encoded into a sequence of invisible characters by this method which can be embedded into the text without changing the visual appearance.Also,it is easy to obtain the author''s information from a piece of text,and more importantly,the text content is protected by the hash code in watermark.According to tests,this method is particularly applicable to the copyright protection of text transmitted over the Internet.关键词
