%X 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 ...
