Abstract :
Novel fragile watermarking algorithm is proposed based on the Fractional Fourier Transform (FRFT) and the blocking method in this paper. Chaotic sequence is converted into a binary 0, 1 sequence to be used as the watermarking information. The blocking method for fragile watermarking algorithm is used to generate the initial value of the chaotic sequence. Good performance in experiments shows its excellent function for preventing tampering.
