一种基于数字水印的媒体自动识别技术

将日后需要用计算机进行识别的信息实现以水印的形式嵌入载体中，可以不影响载体感官效果，同时使得用计算机识别该载体内的特征信息变得简单可行。针对特定领域提出了实现该目标的一个模型，并给出了相应的算法。算法具有优良的性能，可以快速有效地满足识别要求，识别率很高，同时也满足了信息安全方面的要求。

Digital watermarking-based media automatic identification technology

It makes recognition simple and feasible with a computer if we embed its feature information in this entity in the form of digital watermarking, meanwhile, it will not affect its sensibility. In this article, a mode was set up to realize this idea in some particular areas, and related algorithm was also given out. And it is an algorithm with high performance, and the goal of recognition and security can be also archived effectively with it.
