We propose a new scheme for the oblivious/blind robust watermarking of digital images based on independent component analysis (ICA). Most watermarking schemes based on ICA need additional information in watermark extraction process. But it is not encouraged because storing and transferring these additional information is not very convenient in some situations. A novel dividing image blocks is utilized in the paper that overcomes the shortcoming that watermark extraction based on ICA need additional information. The watermarking scheme, undergoing a variety of experiments, has shown its robustness against many attacks, e.g. JPEG, filter, gray scale reduction etc; it also exhibits a capability in image authentication.
