摘要：This paper presents a novel robust invisible watermarking method for still images. The scheme is implemented on hardware, and it can be incorporated with the lossless JPEG2000 compression standard. We have implemented Cohen-Daubechies-Favreau (CDF) 5/3 wavelet filters with lifting scheme which requires less hardware and they are also the basis of lossless JPEG2000. Its modular structure is well suitable for hardware implementation and it is more efficient use of power and chip area. The objective of the hardware assisted watermarking is to achieve low power usage, real-time performance, robust and ease of integration with existing consumer electronic devices such as scanners, cameras and handy camcorders. The proposed scheme of watermarking is tested with StirMark software which is a one of the benchmarking software for watermarking scheme. The experimental result shows that the proposed scheme of watermarking is robust against most of the geometric attacks such as scaling and rotation. We have proposed a dual detection technique for watermark detection which is a novelty of our algorithm.
