JPEG-Resistant Robust Watermarking with Applications to Visual Secret Sharing Techniques

Robust watermarking has emerged as a pivotal field in digital security, particularly for protecting intellectual property. This study introduces a robust watermarking framework specifically engineered to withstand JPEG compression attacks. To evaluate our scheme, several performance metrics should be considered, including robustness against intentional JPEG compression, embedding capacity, and the perceptual quality of watermarked images. For practical applications, we choose the quick response code to serve as the watermark, and we extend our evaluation to high-resolution pictures, both captured by the authors and obtained on the Internet with no copyright issues. These images possess resolutions that are dozens-of-times higher than conventional test images, facilitating a vastly increased capacity. This expanded capacity makes the integration of visual secret sharing practical, adding an additional layer of cryptographic protection to the watermarking scheme. Simulation results present the effectiveness of our implementation, demonstrating that our approach achieves a superior balance between data integrity and visual fidelity, even when subjected to rigorous attack conditions.
