An Implementation of Reversible Watermarking for Still Images

This paper presents a reversible data hiding algorithm. It provides good capacity by exploiting the correlation between neighboring pixels. Its application is appropriate in medical, cartographic and forensic images because it´s possible to recover the original image and what´s more the watermarked image is of very good quality so it can be used in some cases not very demanding. Its applications include authentication, integrity control, or inserting metadata.
