Abstract

The evolution for image manipulation tools and the wide distribution of images through the internet have led to the need for image copyright protection and forgery detection tools. In this paper a three models of a Robust-Fragile Dual watermarking system are proposed for the proof of ownership and image authentication. The proposed system has two main stages the embedding stage and the extraction stage. The embedding of the watermarks, which are the biometric signature for the image's owner, is done in the DCT domain of the cover image. The proposed system with its three models is tested against attacks and it gives satisfactory results in the three models for robustness and fragility and data payload.
