Abstract: A detecting data processing apparatus determines whether one or more code words of a predetermined set of code words are present in a suspected version of a material item. The apparatus comprises a registration processor operable to associate samples of the suspected version with samples of a copy of the original material item, a recovery processor and a detection processor. The recovery processor is operable to generate a recovered code word by comparing the registered copy of the original and the suspect material items. The detection processor is operable to detect one or more code words from a correlation between the recovered code word and the code words from the set. The registration processor is operable to form at least one reduced-bandwidth-version of the material item and to associate the suspected version and the copy of the material item in accordance with a comparison between the reduced-bandwidth-versions of the suspected version and the original material item.

Abstract: The invention relates to watermarking systems, which irregularly change the embedded watermark so as to avoid hacking the system by averaging-attacks. In averaging attacks, segments of the watermarked signal are accumulated. This causes the host signal to be cancelled out whereas the embedded watermark accumulates coherently. A watermark A thus determined is then subtracted by a hacker from the watermarked signal. This invention exploits the insight that the hacker does not know when the embedded watermark changes (from A to B, or from A to none). Accordingly, fragments of the hacked signal will contain the negative watermark—A being unintentionally embedded by the hacker. This causes the watermark detector to produce a correlation peak of opposite polarity. The invention resides in the detection of such a negative peak, and concluding therefrom that the signal has been tampered. The payload of the watermark is preserved. This provides the possibility to trace back the hacker.
Abstract translation: 本发明涉及水印系统，其不规则地改变嵌入的水印，以避免通过平均攻击来攻击系统。 在平均攻击中，水印信号的段被累积。 这使得主机信号被抵消，而嵌入的水印相干地累积。 这样确定的水印A然后由黑客从加水印的信号中减去。 本发明利用了黑客不知道何时嵌入的水印变化（从A到B，或从A变为无）的见解。 因此，被黑客信号的片段将包含由黑客无意嵌入的负水印-A。 这使得水印检测器产生相反极性的相关峰值。 本发明在于检测这样一个负峰值，并从中得出结论信号已被篡改。 保留水印的有效载荷。 这样可以追溯黑客。

Abstract: Distributing information, including the steps of watermarking the digital content, distributing the digital content using a multi-source system, and partially fingerprinting digital content at each stage of moving information from a point of origin to the viewer. “Adaptation” of the digital content to the recipient includes maintaining the digital content in encrypted form at each such intermediate device, including decrypting the digital content with a key unique to both the device and the specific movie, selecting a portion of the watermark locations into which to embed information, embedding fingerprinting information into those locations sufficient to identify the recipient, and encrypting the fingerprinted digital content with a new such key.

Abstract: Residue calculating sections respectively obtain residues which take a plurality of integers as modulus, with respect to a user ID. The plurality of integers are stored in modulus storage sections and are prime to each other. Based on these residues and parameters stored in a coding parameter storage section, component codes constructed by continuous sequences of 1 and 0 using a predetermined number of bits as a unit are respectively generated by component code generating sections. These component codes are concatenated by a concatenating section, thereby to obtain a code to be embedded, which constructs watermark information.

Abstract: 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. [DKI]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.
Abstract translation: 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。
[DKI] 因此，像无防手套的盗贼一样，数码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。 -

Abstract: A method of concealing data in images imperceptibly alters curves therein, such as through adding a value representing the data to be hidden to each of a number of B-spline control points representing the original curve. The altered control points characterize the imperceptibly altered curve, which replaces the original curve in the image. The altered control points may be later extracted from the image and compared with the original control points to determine the hidden value. Prudent selection of the values altering the control points as well as an iterative alignment-minimization algorithm in the detection process provides protection against numerous techniques for preventing the hidden values from being recovered.
Abstract translation: 隐藏图像中的数据的方法不可察觉地改变其中的曲线，例如通过向表示原始曲线的多个B样条控制点中的每一个添加表示要隐藏的数据的值。 改变的控制点表征了不可察觉地改变的曲线，这取代了图像中的原始曲线。 可以稍后从图像中提取改变的控制点，并与原始控制点进行比较以确定隐藏值。 改变控制点的值的谨慎选择以及检测过程中的迭代对齐最小化算法提供了针对许多防止隐藏值被恢复的技术的保护。

Abstract: This invention provides a method for identifying a purchaser who purchased content from which an illegal copy was produced. A provider system encrypts a content purchased by the purchaser using a public key of a purchaser system and sends the encrypted content to the purchaser system. The purchaser system creates a digital signature of the content with the use of a private key of its own and embeds the created digital signature into the received content. When an illegal copy is found, the provider system verifies the digital signature, embedded in the illegal copy as a digital watermark, to identify the purchaser who purchased the content from which the illegal copy was produced.
