Since the traditional adaptive watermarking technology cannot change the embedded area of the watermark according to the characteristics of the image itself, and its ability to resist geometric attacks is weak, a watermarking embedding method based on SIFT feature extraction combined with DWT-SVD is presented. Firstly, the SIFT feature is extracted from the image, then a feature point with good robustness is selected using RANSAC algorithm, a suitable size watermark area is selected according to the feature point, and then the watermark is embedded into the original image with DWT-SVD algorithm. The watermark embedded by SIFT transformation combined with DWT-SVD algorithm has a better visual effect. When the watermarked image is not attacked, the watermarks can be extracted losslessly. When it is attacked, the quality of the extracted watermarks is good, the NC value is higher than 0.96, and the time complexity and space complexity of the algorithm are small. Experiments show that this scheme has good robustness against rotation attacks at any angle and conventional image processing attacks, and can protect digital products.
