First wavila challenge: several considerations on the security of a feature-based synchronisation scheme for digital image watermarking
Year: 2005
Type: conference-paper
Abstract: This paper presents a study on the security of feature-points based synchronisation watermarking methods. The studied scheme, based on the Harris detector, is presented. An analysis of the feature point de- tector enables then to draw two different attacks. The first attack called the competition attack is performed to lure the detector by increasing the response of neighbouring feature points. The ranking attack affects the final ranking which is used to extract the most robust feature points. Examples are given on toy images and the security of feature-based wa- termarking scheme is afterward discussed.
