Abstract :
This paper proposes a secure scheme for images captured by digital camera. In this scheme, both semi-fragile and robust watermarks are employed during image capture. The image´s frequency contents and the owner´s biometric data are used to generate watermarks that are more secure than that of previous techniques. The proposed scheme can achieve image authentication and copyright protection
