摘要： Techniques are disclosed to enable utilization of randomly-occurring features of a label (whether embedded or naturally inherent) to provide counterfeit-resistant and/or tamper-resistant labels. More specifically, labels including randomly-occurring features are scanned to determine the labels' features. The information from the scan is utilized to provide identifying indicia which uniquely identifies each label and may be later verified against the label features that are present to determine whether the label is genuine. In a described implementation, the identifying indicia may be cryptographically signed.

摘要： An implementation of a technology is described herein that facilitates rights enforcement of digital goods using watermarks. More particularly, it is a fingerprinting technology for protecting digital goods by detecting collusion as a malicious attack and identifying the participating colluders. If a digital pirate breaks one client and enables this client to avoid watermark detection, all content (both marked/protected an unmarked/free) can be played as unmarked only on that particular client. However, to enable other clients to play content as unmarked, the digital pirate needs to collude the extracted detection keys from many clients in order to create content that can evade watermark detection on all clients. The described implementation significantly improves collusion resistance through a fingerprinting mechanism that can identify the members of a malicious coalition even when their numbers are several orders of magnitude greater than what conventional collusion-protection schemes can accomplish. However, in this scenario each member of the malicious coalition leaves a fingerprint in every digital good from which the estimated watermark is subtracted. Thus, like a burglar without gloves, the digital pirate leaves her fingerprints only when she commits a crime. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要翻译： 这里描述了一种使用水印来促进数字商品的权利实施的技术的实现。 更具体地说，它是通过检测串通作为恶意攻击并识别参与的共谋者来保护数字商品的指纹技术。 如果数字盗版打破了一个客户端，并且使得该客户端能够避免水印检测，则所有内容（无标记/免费标记/保护）只能在该特定客户端上被标记为无标记。 然而，为了使其他客户端能够以无标记的方式播放内容，数字盗版者需要从许多客户端中抽出提取的检测密钥，以创建可以避免所有客户端上的水印检测的内容。 所描述的实现通过指纹机制显着地提高了共谋阻力，其可以识别恶意联盟的成员，即使它们的数量比常规串谋保护方案可以实现的数量级大几个数量级。 然而，在这种情况下，恶意联盟的每个成员在每个数字商品中留下指纹，从中减去估计的水印。 因此，像没有手套的防盗器一样，数字盗版者只有在犯罪时才会留下指纹。 本摘要本身并不旨在限制本专利的范围。 在所附权利要求中指出了本发明的范围。

摘要： Described herein is an audio watermarking technology for detecting watermarks in audio signals, such as a music clip. The watermark identifies the content producer, providing a signature that is embedded in the audio signal and cannot be removed. The watermark is designed to survive all typical kinds of processing and all types of malicious attacks that attempt to remove or modify the watermark from the signal. The implementations of the watermark detecting system, described herein, support quick, efficient, and accurate detection of watermarks by the specifically designed watermark detecting system. In one described implementation, a watermark detecting system employs an improved normalized covariance test to determine the presence of a watermark using less expensive materials (hardware), quicker calculations, and a more accurate test (than the original correlation test). In other described implementations, a watermark detecting system employs a cepstrum filter and dynamic processing to minimize the affect of the “noise” in the watermarked signal. The “noise” is the original content of the signal before such signal was watermarked. In still another described implementation, a watermark detecting system employs a mechanism for random detection threshold so that the act of watermark detection does not provide decipherable clues to a digital pirate as to the value or location of the embedded watermark.
