On the security of ownership watermarking of digital images based on singular value decomposition

Abstract

We show that the two countermeasures proposed in a paper on the security of ownershipwatermarking of digital images based on singular value decomposition by Loukhaoukha and Chouinard do not solve the false-positive detection problem in contrast to designers' claim and therefore should not be used for proof of ownership application. © 2011 SPIE and IS & T.
