数字水印技术是近年来提出的一种多媒体数据版权保护的方法。在本文中，我们解决的能力，不可见水印方案，以解决版权问题。我们将表明，合法的所有权不能单独解决目前的水印方案。此外，在水印程序没有标准化的情况下，任何人都可以声称对任何水印图像的所有权。具体来说，我们提供了伪造水印方案，可以在水印图像上执行，以允许合法所有权的多个索赔。本文还提出了不可逆水印方案，并讨论了数字水印在识别合法版权所有者方面的作用。这些结果，再加上最近对一些图像水印的攻击，进一步意味着我们必须仔细重新思考我们的方法，图像的不可见水印，并重新评估这种数字版权保护手段的承诺，应用和局限性。
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, anyone can claim ownership of any watermarked image. Specifically, we provide counterfeit watermarking schemes that can be performed on a watermarked image to allow multiple claims of rightful ownerships. We also proposed non-invertible watermarking schemes in this paper and discuss in general the usefulness of digital watermarks in identifying the rightful copyright owners. The results, coupled with the recent attacks on some image watermarks, further imply that we have to carefully re-think our approaches to invisible watermarking of images, and re- evaluate the promises, applications and limitations of such digital means of copyright protection.
