Entropy Based Secure and Robust Image Watermarking Using Lifting Wavelet Transform and Multi-Level-Multiple Image Scrambling Technique

Online communication platforms prompted the versatility and easiness in communication. That’s why these are witnessing abrupt rise their usage. On other side, it can lead to unauthorized replication alteration of digital images that raises security concerns. Ensuring robustness, imperceptibility watermarking has become a critical task. SVD-LWT technique along with entropy is presented Y-channel YCbCr color space utilized implant secret information. The paper also uses multilevel-multiple image scrambling approach enhance security. To estimate performance, fidelity parameters namely PSNR, NPCR, UACI, SSIM, UIQI NCC used.
