Analysis of robustness in multiple watermarking using edge detection and wavelet transforms

Abstract

In this paper we analyses the robustness of multiple watermarking in color images using edge detection and Wavelet transforms. In a digital world, an unlimited number of copies of original can be easily distributed and forged. One way to protect the Intellectual Property Rights of a digital content is to secretaly embed data in the content to identify the owner. Digital watermarking is an effective way to deter content users from illegal distributing. The proposed work is based on various discrete wavelet transforms that embeds and extracts multiple watermarks in color images with the analysis of robustness against various attacks.
