Abstract: 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.

The data management system also monitors access of the application to the contents by associating information for the application brought into an activated status with information for the accessed contents. The data management system also enciphers the contents with the application information when the activated application writes the contents into the storage while deciphering the contents with the application information when the activated application reads out the contents.

Abstract: A stream data recording apparatus records stream data in such a manner that the head of each video coding unit and the head of a series of audio coding unit corresponding to each video coding unit contained in the stream data coincide with the heads of access units of a recording medium. Utilizing the structure of stream data so recorded and the random accessibility of the recording medium, a stream data replaying apparatus and a stream data editing apparatus replay or edit the stream data freely on a video coding unit basis. By replacing stream data recorded on the recording medium on a video coding unit basis, the recording apparatus realizes endless recording that does not require complex file manipulation.

Abstract: 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.
