一种基于关联伪随机序列的数字水印镶嵌与检测技术
AN ASSOCIATED PSEUDORANDOM SEQUENCES TECHNIQUE FOR DIGITAL WATERMARK EMBEDDING AND DETECTION
摘要
Abstract
An associated pseudorandom sequences technique, which is used in encryption watermark embedding and detecting, is researched for multimedia copyright protection. It makes the embedded data associate with the embedded position, so the watermark is not easy to be attacked. Covariance is used to detect watermark, which may reduce the influence of initial data or chaos in partially. The discussion of the watermark' s hidden ability and robustness shows that this technique has satisfied result, so it can be widely used.关键词
