Digital watermarking has recently emerged as a solution to the problem of providing guarantees about copyright protection of digital images. However, several problems related to robustness of invisible watermarking techniques to malicious or nonmalicious attacks still remain unsolved. Whereas visible watermarking is an effective technique for preventing unauthorized use of an image, based the insertion of a translucent mark, which provides immediate claim of ownership. This paper describes an

Watermark positioning deals with the problem of selecting the most suitable image position to place the visible mark. Our efforts have been directed to find the best region of the host image where watermark insertion can ensure robustness and unobtrusiveness to the watermark.
