Digital Watermarking is an excellent tool at the disposal of the owners of the digital content to protect their Intellectual Property Rights (IPR). In this paper we present an attack on several watermarking schemes that forgo their claims of proving ownership of digital content. The attack takes the advantage of one-to-many relationship between the Singular value matrix and the decomposing matrix. In this paper we prove that the two ways one-to-one relationship between the watermark and the watermark dependent pattern to be hidden in the image as a necessary condition to invalidate the multiple claims of ownership of digital content. We also recommend the standardization of watermarking schemes and registration of watermarks with legal authorities so as to make the system transparent.
