Abstract
ABSTRACT tectable by dedicated software or hardware and very A watermark is a perceptually unobtrusiGe signal em-bedded in an image, an audio or video clip, or any other other multimedia asset. Its purpocie is to be a label which is holographically attached to the content. Moreover, it can only be removed by malicious and de-liberate attacks (without a great loss of content qual-ity) if some secret parameter K is known. In con-trast, a watermark should be readily detectable by elec-tronic means. This implies that electronic watermark detection is only feasible if the watermark detector is aware of the secret K. In many watermarking busi-ness scenarios the watermark detector will be available to the public as a black box D. The following question is therefore justified: can the secret K be deduced from the operation of the black box D? And if yes, what is the complexity of this process? In this paper we will address these questions for a large class o,F watermark-ing schemes. This work is an extension oj earlier work at Philips Research [l]. 1.
