Universidad Nacional de Córdoba. Departamento Universitario de Informática; Argentina. Fil: Vargas, Laura. Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales. Laboratorio de Redes y Comunicaciones; Argentina. Security problems that recently appeared in transmission and storing of digital content can be solved by using watermarking. Reversible watermarking is the election in medical and defense imagery because these security systems are able to restore the original image after extracting the hidden information. In this document an intelligent reversible watermarking scheme is proposed. It is based on the difference expansion method developed by Tian and it is helped by genetic algorithms to improve the imperceptibility of the mark for a fixed payload. Furthermore, it is shown that the image can be divided in blocks watermarking each one, so if an adulteration takes place, it can be determined the block where this happened http://seekdl.org/nm.php?id=6185 Fil: Vargas, Laura.
