摘要： PROBLEM TO BE SOLVED: To provide an abstraction method of electronic watermark information which is possible to abstract electronic watermark information from image data to which geometric reproduction is added without using the electronic watermark for calibration. SOLUTION: Processes for deciding whether the watermark information is embedded in pixel data or not, are executed by adding geometric reproduction to the image data until the information is confirmed to be embedded in the pixel data, by abstracting the pixel data in a predetermined position on X-Y coordinates used when the watermark information is embedded from image data in which the electronic watermark information is embedded in arbitrary pixel data, and comparing the data with the reference values.

摘要： PROBLEM TO BE SOLVED: To guarantee both or either of a content holder and a content user to have a distribution route or restrict the illicit distribution of digital content. SOLUTION: A provider ID of a provider 40 distributed by the provider 40 is embedded with a digital watermark. A terminal 50 checks a certificate 41 of the provider 40 and stores a pair 56 of the provider ID and a content ID written in the certificate 41 at a license management part 55. The terminal 50 detects the watermark of the provider ID when using the content and determines whether the content may be used or not by checking if the provider ID stored in a tampering resistant area matches with the provider ID embedded in the watermark.

摘要： PROBLEM TO BE SOLVED: To provide a technology for enhancing the performance of padding a digital watermark inexpensively while shortening a processing time in a program for padding motion picture data with a digital watermark.
SOLUTION: At the time of padding a frame constituting motion picture data with a digital watermark, processing for reusing calculation values of filtering results in a past frame is carried out. A decision is then made whether filtering is carried to a present frame out or not, and filtering is not carried out for a part of an entire frame. Filtering is carried out for an objective frame and the filtering results are stored. For a nonobjective frame, filtering results of a past frame are read in and reused. Furthermore, a decision is made whether the padding of a digital watermark is required or not by determining the frame type, and only a limited part of the entire image of the frame is padded with a digital watermark.

摘要： PROBLEM TO BE SOLVED: To detect electronic watermark information without incurring an increase in memory capacity with respect to moving picture data with various scan systems and image sizes.
SOLUTION: An electronic watermark information detecting apparatus 1 converts decoded moving picture data 4 with watermark into standard moving picture data 5 with the smallest data size among assumed types of moving picture image data. Further, standard coordinates used for particularizing an embedded position of the electronic watermark pattern are magnified/reduced. Then the electronic watermark information is detected from a prescribed position on the magnified/reduced standard coordinates particularized by the electronic watermark pattern in fields of the standard moving picture data 5.
