摘　　要：网页水印在网页版权保护和防仿冒篡改等方面具有重要应用,现有的网页水印技术主要是利用HTML对一些格式变化的不敏感性进行水印信息的嵌入,这类方法嵌入的水印信息与网页内容严重分离,水印的隐蔽性不强,容易受到攻击。文中提出一种新的基于空样式的网页水印方法,利用HTML对于没有定义的样式不做任何操作的性质,将水印信息转换为没有内容定义的空样式,并嵌入到网页的HTML代码中,使得水印信息与HTML代码联系紧密,隐蔽性强,不易被检测和攻击,同时拥有较大的水印信息容量。与现有方法相比,所提方法具有较大的优越性。Webpage watermarking has important applications in webpage copyright protection and anti-tampering.The existing webpage watermarking methods mainly embed watermark information by using the insensitivity of HTML to some format changes.Such methods have the problems that watermark information is separated from the webpage contents,which makes the watermark less concealed and vulnerable to attacks.This paper proposed a new webpage watermarking method based on empty styles.Making use of HTML’s feature that it does no operation to a style without content definition,the method transforms watermark information into empty styles and embeds them into the HTML code.The embedded watermark information is closely linked with the HTML code and is of strong concealment.It is not easy to detect and attack,and has a large watermark capacity as well.Compared with the existing methods,the proposed method is more superior.
