摘要

A novel binary watermarking algorithm has been proposed based on the Fractional Fourier Transform (FRFT) and the digital watermarking techniques. The 0, 1 sequence are corresponded to two different random sequences here by considering the strong practicability of the binary watermarks and the strong robustness of the sequence watermarks. The good performance in experiments shows the strong robustness of our proposed method, especially under strong shear attacks. © 2012 IEEE.
