The Study Of Digital Watermarking Based On ECC

Digital watermarking is an important branch in network and information security, the research of this area has strong application background in the security of digital media and the protection of copyright.One of the most important research area is how to design the embedding algorithm with strong robustness.We aim to investigate the embedding algorithms of watermarking with good properties.In this paper,a new self-adapting watermarking algorithm was proposed based on Goppa code.The experimental results demonstrate that the.watermarks generated with the proposed algorithm are perceptually invisible and robust aga.inst JPEG compress,noise,median filtering and commonly used image processing techniques.An algorithm of watermarking used JND Threshold presented by Yuan Jiaxin and Ma Yunsheng. Based on it,a new DWT block based watermarking algorithm was proposed based on Goppa code. The algorithm has follow feature compare to that of Yuan's:1)The algorithm has strong robustness against sharpening and cutting.2)Harmonizing the conflict between imperceptible and robustness.Finally,the algorithm was implemented and forecasted the future work of watermarking used ECC.
