    Abstract: A watermarking system comprises an encoding data processor operable to generate at least one marked version of an original item of material by introducing one of a predetermined set of code words into a copy of the original material item. The encoding processor comprises a code word generator operable to form the code word by generating a plurality of code word coefficients, and an encoder operable to combine the code word coefficients with the material item, and an adaptation processor. The adaptation processor is operable to adapt the strength of the code word coefficients or the material item samples in accordance with a relative sensitivity of the material item samples to carry the code word coefficients. The strength of the watermark is therefore adapted in accordance with the sensitivity of the material item to carry watermark code word coefficients. As a result there is a reduced likelihood of an attacker identifying parts of the material item to which the watermark code word has been added. A likelihood of a successful attack is thereby reduced whilst maintaining a desired false negative detection probability. The watermarking system finds particular application in identifying a point of distribution of pirate copies of video material generated by capturing the watermarked image, using, for example, a camcorder in a cinema.

    Abstract translation: 一种水印系统包括：编码数据处理器，可操作以通过将预定的一组代码字中的一个引入原始物料的副本来产生原始物料的至少一个标记版本。 该编码处理器包括一个代码字生成器，用于通过产生多个代码字系数来形成代码字，以及一个编码器，用于将代码字系数与该物料项组合，以及一个自适应处理器。 适应处理器可操作以根据材料项目样本的相对灵敏度来适应码字系数或材料项样本的强度以携带码字系数。 因此，水印的强度根据物质项目的灵敏度来适应携带水印码字系数。 结果，攻击者识别出已经添加了水印码字的物质项目的部分的可能性降低了。 从而降低成功攻击的可能性，同时保持所需的假阴性检测概率。 水印系统在识别通过使用例如电影院中的摄像机捕获水印图像而产生的视频资料的盗版副本的分布点上发现了特定的应用。

    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. nullDKInullThus, 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。 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 digital image signal is watermarked by locally changing geometric features of the image. The watermark consists of a pseudo-random, dense subset of image pixels, e.g., a pattern of lines (20). A number of significant image pixels (21,22,23), i.e., pixels which give the highest response to a predetermined processing operation, is determined and then moved (24) to the vicinity (null) of the line pattern. As a result of this nullwarpingnull, the majority of significant image pixels (21,22) is eventually located within the vicinity of the line pattern. At the receiver end, the most significant pixels of an input image are again determined. The image is a watermarked image if a statistically high percentage lies within the vicinity of the line pattern.

    Abstract translation: 数字图像信号通过局部改变图像的几何特征来加水印。 水印由图像像素的伪随机密集子集（例如，线图案（20））组成。 确定许多有意义的图像像素（21,22,23），即对预定处理操作给出最高响应的像素，然后移动（24）到线图案的附近（delta）。 作为这种“翘曲”的结果，大多数重要图像像素（21,22）最终位于线图案附近。 在接收端，再次确定输入图像的最高有效像素。 如果统计学上高的百分比位于线条图案的附近，则图像是水印图像。

    Abstract: The method for water-marking digital books with parameters includes developing, for each parameter, a new typeface on the basis of a pre-existing typeface, by creating at least one new code/glyph pair. The method includes developing a new coded text on the basis of the pre-existing coded text by replacing, in the pre-existing coded text, at least one code or group of codes from the pre-existing typeface. The method further includes allowing display of a character or a combination of characters from the digital book by the code or the group of codes from the new typeface allowing display of the graphically identical character or combination of characters on any screen. The code/group of codes from the new typeface has/have at least the code from the new code/glyph pair. The method also includes providing the new coded text and the new typeface as a water-marked digital book.

    Abstract: First and second patterns are formed on a substrate. A spatial offset between the patterns is determined, and stored for later use in authenticating the substrate. (One or both of the patterns may convey steganographic information. One pattern may be printed, while the other may be embossed.) A smartphone can sense these patterns, determine the spatial offset, and check whether the determined offset matches the earlier-stored offset, to judge whether the substrate is authentic. Another arrangement effects serialization of product packaging by use of paired patterns (at least one of which is typically a watermark pattern) applied in a manner causing a spatial offset between the patterns to progressively vary along a length of a printed web. Still other arrangements involve substrates conveying patterns that degrade over time, e.g., indicating freshness or pressurization condition. A great variety of other features and arrangements are also detailed.
