A METHOD FOR DIGITAL IMAGE WATERMARKING USING ICA

Abstract

Digital watermark technology has been developed quickly during the recent few years and widely applied to protect the copyright of digital image. A digital watermark is the information that is imperceptibly and robustly embedded in the host data such that it cannot be removed. This paper proposes a method based on the independent component analysis (ICA) for the digital image watermarking. The experimental results indicate that the presented approach is remarkably effective in detecting and extracting the digital image watermark. The problem of robust watermarking is also tested to demonstrate the effectiveness of the proposed approach.
