摘要： A justification/authentication personal certificate system stores in a remote database a counterpart of an identifier and a digital watermark contained in the personal certificate. The personal certificate includes the digital watermark embedded in an authentic image such as a facial photograph, a retinal scan, or a fingerprint. When the personal certificate is used, the authentic image is read from the personal certificate, and the digital watermark information is extracted. The digital watermark information and the identifier are compared with the counterparts stored in the database. If the extracted digital watermark information is identical to the information in the database, then the personal certificate is judged to be unjustifiable. In one embodiment, at least one of the identifier and digital watermark are changed each time the system justifies the personal certificate.

摘要： A learning-support device offers a sufficient learning effect even in a field of learning that sets its goal on mastering a motion itself. A question-screen display part displays a question-screen composed of a question and moving images as choices for an answer. A selection reception part receives a user-selection indicating which of the moving images on the question-screen is selected by a user. A correct/incorrect determination part determines whether the user-selection is correct or incorrect. When the user-selection is determined as correct, a correct-answer-explanation-screen display part displays a correct-answer-explanation-screen including an explanation for the correct answer and the correct moving image. When the user-selection is determined as incorrect, an incorrect-answer-explanation-screen display part displays an incorrect-answer-explanation-screen including an explanation for the incorrect answer and the correct moving image.
