A Joint Encryption/Watermarking Algorithm for Secure Image Transfer

This paper presents a method combining encryption and watermarking for secure images transfer. The proposed solution gives access to the outcomes of the image integrity and of its origins as its attachment to one user even if the image is stored encrypted. This method is based on the combination of encryption algorithms publicprivate keys and secret keys, and watermarking. The algorithm for image encryption uses a secret key. We encrypt the secret key with an asymmetric algorithm. This encrypted secret key is then inserted into the encrypted image using watermark algorithm.
