摘要
Digital watermarking technology for color images is not robust and has low security and other shortcomings. We thus propose an embedding and blind extraction algorithm based on compressive sensing. First, complex image blocks were selected in images as embedded objects using a block strategy. Next, compressive sensing transformation was applied to the target blocks and watermark, thereby obtaining their measurement matrixes. Finally, the watermark information was embedded by singular value decomposition of the measurement matrixes. The experimental results showed that the algorithm exhibited relatively high robustness when the watermark information was safe.
