摘要：

A kind of waterrmark-inserting and extracting algorithm by combining discrete orthogonal wavelet transform with chaotic technique is proposed. Firstly the transformed digital watermarking is encrypted by logistic. Wavelet transform is implemented to the digital image to be inserted watermark. The encrypted watermark is inserted into the low-frequency wavelet coefficients. Inverse wavelet transform is done to obtain the inserted watermarking image. The original watermarking image is extracted by anti-Arnold transformation. The experimental results show that the proposed algorithm has good invisibility and good robustness to the general image attack, such as noise, the filter, rotation, the compression and so on.
