摘要
数字水印的嵌入作为数字作品的版权保护手段,相关领域的学者提出了很多算法,但是面临各类攻击时依然难以达到版权的保护作用,该文提出基于小波变换的水印验证策略,在水印检测之前首先做完整性判断,可以很好的知晓水印数据在传播过程中遇到的攻击情况。
Digital watermark embedding as means of digital copyright protection,Scholars in related fields a lot of algorithms,But when faced with all kinds of attacks are still difficult to achieve copyright protection,in this paper,wavelet-based watermark verification strategy,Before the first to do watermark detection to determine the integrity of,With good knowledge of the watermark data in the dissemination of the situation encountered in the process of attack.
