Watermarking Techniques with Yuv Layered Approach

Abstract

Watermarking is a technique used to embed hidden data or identification information within digital multimedia. With the rise of the internet, the creation and distribution of digital data (images, video, and audio files) have significantly increased, leading to issues concerning content protection and ownership proof. Digital image watermarking addresses these issues by embedding a watermark into the data to assert ownership and protect rights. To safeguard the watermark from counterfeiters, it must be embedded in locations resilient to various attacks (rotation, scaling, compression, cropping, filtering, and blurring). Effective watermarking hides a message signal within a host signal without perceptual distortion. This paper adopts a hybrid transformation approach to modify the cover image's singular values rather than the DWT sub-bands, making the watermark resistant to attacks while maintaining the image's original state. Simulation results support the effectiveness of the proposed methods.
