    Abstract: A system for authenticating digital data capable of preventing change or disguise of data by improvement or interchange in case of no confidentiality in the data itself so as to maintain the data. When writing digital data from an input device to a memory and transferring the digital data from the memory to a receiving device, device authentication is performed between the input device and the memory and between the memory and the receiving device respectively. At the same time, when writing digital data to the memory, in the case of implementing on the digital data an electronic signature by a one-way hash function and also reading from the memory and transferring the digital data, the implemented electronic signature is decrypted so as to transfer the digital data after ensuring that it has not been changed since it was recorded. Thus, it is possible to prevent change or disguise of data by improvement or interchange in case of no confidentiality in the data itself so as to maintain the data.

    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: The target of stereoscopic processing for creating a stereoscopic image from an original image is restricted to specific original images. An authentication image creation device changes the pixel data of a target pixel within an original image into update data that are created from the pixel data of pixels adjacent to that target pixel. On the other hand, in advance of stereoscopic processing of the original image, an image processing device compares the pixel data of the target pixel in that original image with authentication data that are created from the pixel data of pixels adjacent to that that target pixel, and based on the results of that comparison, determines whether or not stereoscopic processing of that original image is to be permitted.
