Copyright Protection in Insecure Communication Channels Using a Robust Digital Picture Watermark
With the transition from analogue to digital technology, worries about the security and authenticity of digital material and data have grown. Owners of any type of digital material seek out and experiment with innovative copyright multimedia content protection solutions. In recent years, multimedia protection has become a challenge, and researchers are still looking for and testing new and more effective methods to solve the problem. This thesis project aims to improve the visibility and intensity of invisible watermarking in a typical aeroplane using multilayer Discrete Wavelet Transform (DWT) and embed two marks in the image for verification and copyright purposes. When unprotected digital material flows across an unsecured channel Based on five active locations and the usage of two marks, a new watermarking method has been suggested. Marketing pictures will be included in the assault test set, in addition to the extraction procedure. The test technique was used to evaluate the SNR, PNSR, MAE, and RMSE values in both visual modes and post-attack pictures, as well as the invisibility of watermarking before and after the assault. Our lab results demonstrate that our pictures are both SNR and PNSR valuable, with excellent durability and quality.
