1 March 2007 Tangential sensitivity analysis of watermarks using prior information
Author Affiliations +
A novel sensitivity analysis attack is introduced in the context of the BOWS (Break Our Watermarking System) contest.1 The method follows the boundary of the detection region, rather than directly estimating the normal to the boundary, so it is applicable even if the boundary is not well approximated by a hyperplane. To improve efficiency, we employ search directions scaled using a model of perceptual masking.
