A self-adaptive blind watermarking algorithm based on transform domain was proposed by combining lifting wavelet transform with fuzzy cluster analysis. Lifting wavelet transform were used to obtain the low frequency subgraph efficiently. In low frequency subgraph, FCM and HVS were combined to divide the texture region for embedding watermark. And the watermark image was encrypted by chaotic map. Contrastive attacking experiments show that this algorithm has preferable transparency and robustness, and can resist various types of attacks effectively.

Abstract In recent years, there has been growing interesting in image encryption based on chaotic maps and wavelet transform. In this paper, a novel scheme for image encryption based on chaotic maps and reversible integer wavelet transform is proposed. Firstly, the cipher key which is related to plain-image is used to generate different parameters and initial values of chaotic maps. Then the plain-image is permuted by the order from chaotic maps, and processed by integer wavelet transform. A part of transform coefficient is diffused by the orbits of chaotic maps. Finally, the cipher image is obtained by inverse integer wavelet transform based on the diffused coefficient. Numerical experimental results and comparing with previous works show that the proposed scheme possesses higher security than previous works, which is suitable for protecting the image information.
