Abstract: According to the present invention, authenticities of paper fingerprint information and of document information are collectively determined through formation of an original that is given an encoded image in which both paper fingerprint information and document information are encoded. By collectively guaranteeing identities of the paper form and of the document, it becomes possible to realize the more reliable authenticity guarantee.

Abstract: In a card serving as an external storage device to be inserted into a digital color multi-function printer, features of a reference image and processing rule information indicating processing content to be applied to input image data judged to be similar to the reference image are prestored. Then, in cases where the input image data is judged to be similar to the reference image, the content of a process to be performed on the input image data is controlled in accordance with the processing rule information corresponding to the reference image. This makes it possible to save users the trouble of setting the content of a process to be performed on input image data, and to prevent a shortage of memory capacity of a memory of the image processing apparatus even in cases where there is an increase in the number of reference images.

Abstract: Based on plural kinds of image data produced by changing a layout of input first image data, at least first feature information and second feature information are extracted and stored in a correspondent relation. Third feature information extracted from third image data is compared with the stored first feature information and second feature information. When a result of the comparison shows that the third feature information is matched with one of the first feature information and the second feature information, it is determined that the third image data is identical to the first image data.

Abstract: A data management method that by encrypting and distributing digital content prevents copyright infringement, and that prevents authorization information for decrypting the encrypted digital content from being damaged or otherwise lost. Encrypted content 45 is prepared by encrypting digital content 11 with a content key 44. A portion of the digital content 11 is extracted as sample data 41. A secret key 46, by which the content key 44 is encrypted with user information 14, is embedded as invisible information into the sample data 41, thus preparing watermarked sample data 47. The watermarked sample data 47 is synthesized with the encrypted content 45 to form synthesized data 48. The synthesized data 48 is distributed.

Abstract: The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.
