A Framework For Effective Watermarking Synchronous With Time And Frequency Domain For Resilience To Attacks

Digital watermarking emerges as a very effective tool that provides digital media with the advantages of authentication, integrity verification, ownership protection, and rights management over an unsecured widespread media sharing channel. At present, various watermarking based image security approaches are present. It is found that a lot of research attention is still needed to develop a more robust mechanism in digital watermarking technology to protect digital content from various attacks. The primary purpose of the proposed system is to introduce a cost-effective and robust watermarking scheme that can survive under various image processing attacks and protect the digital content embedded with it. Here, the formulation of the proposed watermarking technique is based on the concept of 2D frictional fryer transformation technique- (FrfT). The idea is to calculate the 2D FrfT of the cover image. In the transform domain, the watermark identifier is used to modify the coefficients in the transform module, taking into account the real and imaginary parts of the cover image. The proposed system also introduces an attack model designed with two commonly known image processing attacks to evaluate the strength of the proposed watermarking scheme. The simulation results demonstrate the effectiveness of the proposed system in terms of PSNR, correlation coefficient, and bit error rate.
