A Novel Method of Invisible Video Watermarking Based on Index Mapping and Hybrid DWT-DCT

Watermarking is widely used in multimedia preservation and communication, which comprises, therefore not limited to, data security validation. Security, readability, imperceptibility, resilience are some of the key advantages this technology. However, there still certain issues that need to be addressed, such as ability withstand a variety assaults without substantially affecting quality value embedded data. Based on its operational domain, watermarking technology may divided into two groups: spatial frequency watermarking. An index mapping-based approach for copyright protection multi-media color videos presented paper. We offer hybrid discrete wavelet transform cosine (DCT) algorithm digital video watermark. Peak signal noise ratio (PSNR), similarity structure measure (SSIM), have been analyze distortion produced by It suggested proposed method provides greater imperceptibility conjunction with each other human visual system it offers higher robustness against different attacks.
