Can Invisible Watermarks Resolve Rightful Ownerships?

Digital watermarks have been proposed in recent literature as the means for copyright protection of multimedia data. In this paper we address the capability of invisible watermarking schemes to resolve copyright ownerships. We will show that rightful ownerships cannot be resolved by current watermarking schemes alone. In addition, in the absence of standardization of watermarking procedures, an...

Digital Image Watermarking: Issues in Resolving Rightful Ownership

In recent literature many strategies for attacking and subverting a watermark have been presented. Such attacks suggest that the ability to embed non-erasable watermarks does not necessarily imply that the watermarking scheme can be used to establish ownership. The main aim of this paper is to formulate necessary and su cient requirements for a watermarking scheme to be able to resolve rightful...

Watermarking Methods for MPEG Encoded Video: Towards Resolving Rightful Ownership

Various digital watermarking techniques have been proposed in recent years as the methods to protect the copyright of multimedia data. However, as pointed out by the IBM research group, the rightful ownership problem has not been properly solved. Currently, there are two proposals to solve the ownership problem. Unfortunately, one proposal lacks a formal proof and the other can be easily defeat...

On Resolving Rightful Ownership's of Digital Images by Invisible Watermarks

Digital watermarking has been recently proposed as the mean for copyright protection of multimedia data. This paper rst 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 particular, we argue that, for the part...
