Design of Watermarking Algorithm Based on Chaos and Discrete Transform

In order to improve the anti detection ability of watermarking and embedding watermark capacity, this paper proposes embedding watermarking algorithm combined with chaotic system chaotic discrete transform. The algorithm uses chaotic system chaotic algorithm, can improve the randomness to embed more watermark bits, and the use of discrete transform technology will be able to destroy the relevance between the pixel vector images, at last, it will improve the embedding capacity, this paper introduces the design method and Realization processes in details. The experiments indicated that, the design of the watermarking algorithm in the carrier image used to embed the watermark embedding experiment, the results show that the PSNR values are greater than 30dB, show that the implicit explicit algorithm has strong robustness, and anti attack ability.
