Abstract
Due to the rapid development of digital technologies, the digital watermarking techniques have been widely used in research to solve some important issues of digital world. One of the most important issues is to apply digital watermarking on color images for copyright protection and content authentication. DWT is very popular for digital watermarking of gray image, but this research paper is the result of experiment of DWT on color images. Basically, a color image consists of R, G, and B channels, if image is in RGB color space. These color channels are matrices, which facilitate us to work on any channel independently of others. In this research paper, R-channel (or red component) is used to analyze the result. The experiment results show that the proposed algorithm keeps the quality of image well and is robust enough to common image processing operations.
