Abstract
A fingerprint-based digital watermark algorithm for image processing is proposed. Firstly, the watermark is done the scrambling by the Arnold transform. Secondly, the digital watermarking is done the chaos encryption by the Tent chaos sequence. Thirdly, the original image is transformed by the discrete Curvelet transformation. Finally, the watermarking image is embedded into detail scale coefficient matrix of Curvelet transform. The experimental result demonstrated that watermarking extraction’s effect is acceptable. Moreover, severe image attacks such as noise, image crop and JPEG compression and so on are survived by the embedded watermarking.
