摘要： An authentication apparatus is provided. A forgery determination threshold is determined on the basis of two types of parameters, a forgery similarity and a forgery difficulty. If a calculated value for an object under test is lower than or equal to the forgery determination threshold, then, it is determined that the object is a biologic object. Thus, easiness in impersonation with a fake of a biologic object that is easy to forge may be reduced, and a false rejection due to a determination in which a biologic object is erroneously determined as a fake may be reduced.

摘要： The apparatus enables a user to recognize the way he is moving his finger with respect to, for example, a sweep-type fingerprint sensor so that the user can easily and surely learn an appropriate way the finger (body part) should be moved. A velocity detecting means detects a velocity at which the body part moves with respect to a sensor, and an image generating means generates an arbitrary pattern, of which a portion corresponding to a position where the body part is located when the movement velocity is detected is altered according to the detected movement velocity, and the generated pattern is shown on a display.

摘要： A frame, which is the data unit, is extracted without decoding MPEG audio data. Then, a scale factor included in the frame is extracted and an evaluation function is calculated based on the scale factor. If the value of the evaluation function is larger than a prescribed threshold value, the speed of the frame is converted. If the value of the evaluation function is smaller than the prescribed threshold value, the frame is judged to be a frame in a silent section and neglected. The speed conversion is made by thinning out frames or repeating the same frame as many times as required according to prescribed rules.
