Abstract

This paper introduces a kind of method based on chaos and fast curvelet transform. At first, the watermark is done the scrambling by the Arnold transform. Then the digital wartermarking is done the chaos encryption by the chebyshev chaos sequences. At last, the watermarking image that has been done the chaos processing is embedded into the intermediate frequency coefficient of image that has been done the fast curvelet transform. The extraction of watermark is the inverse processing of the embedding of watermark.
