In this paper the digital watermarking algorithm deep into the field of integrated circuits combined with the JPEG image watermarking processes and SOPC technology, Verilog HDL language is used to design and implement of a reusable JPEG decoder IP core which can be embedded, realizing the JPEG decoding on FPGA platform and further completing the watermark embedding. The JPEG decoder is tested through the Modalism simulation software and would be revised until the simulation results become correct. Finally, the Altera development board EP2C70F896C6N of CycloneII series is used to complete the system design. The results prove that the system can run well, the program which can obtain a larger increase speed in exchange for consuming a little hardware resource does work.

Watermarking Scheme

With the rapid access convenience of content brought by 5G technology, the integrity protection of content becomes more important. The reversible visible watermarking algorithm has attracted more attention due to its effective content protection. In this paper, a novel improved reversible visible image watermarking scheme based on gradient-weighted class activation mapping (Grad-CAM) and the just noticeable difference (JND) model has been presented. The proposed region of interest (ROI) selection strategy is used to locate the main protected body of images for watermark embedding. Divide the watermark and ROI into nonoverlapping blocks in the same way and then embed the classified two types of watermark blocks into corresponding ROI blocks with the JND model. The optimal bit positions for watermark embedding can be selected adaptively with JND threshold and achieve the tradeoff between the watermark visibility and watermarked image quality. For lossless image recovery and watermark extraction, the recovery information is reversibly hidden into watermarked image. In the experiments, the same process of grayscale images is used to each channel separately for color images watermarking. Besides, there are six aspects in this paper to estimate the proposed scheme; with the comparison to other reversible visible watermarking schemes, experimental results demonstrate the effectiveness of our proposed scheme.
