A Novel Fractional Order Pseudo-random Digital Watermark Algorithm Based on Fractional Calculus
一种基于分数阶微积分的分数阶伪随机数字水印新算法

The paper mainly concerns and studies the application and implementation of fractional calculus to digital watermark algorithm.In the first,it discusses how to implement fractional calculus pseudo-random sequence by the sampling deviation of fractional calculus sinusoidal signal.In addition,it puts forward a fractional calculus based digital watermark algorithm,the security of which depends on the unknown of fractional orders and initial phrases.At last,it proves the imperceptibility and robustness of this ...
