Approaches of Digital Image Watermarking Using ICA

There has been a rapid growth of digital imagery and digital watermark technology. Digital watermark has been 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. An attempt is made to develop two approaches, FastICA algorithm and multicolour channel image watermarking using Independent Component Analysis (ICA). In this paper a method based on the ICA for the digital image watermarking is developed and a modified digital image watermarking technique is proposed.
