Abstract

Digital watermarking has been recently proposed as the mean for copyright protection of multimedia data. This paper first discusses some scenarios in which many current watermarking schemes fail to resolve the rightful ownership of an image. We then identify the key problems and discuss some crucial requirements for a valid invisible Watermark detection. In particu-lar, we argue that, for the particular application of resolving rightful ownership using invisible watermarks, it might be crucial to require that the original image not be directly involved in the watermark detection process. A general framework for validly detecting the invisible watermarks is then proposed. We show the effectiveness of this technique based on some visual-model- based watermarking schemes.
