Apparat og metode for innlegg av håndskrevne data og personlig identifikasjonsapparat og metode

摘要

There are provided a device and method for enabling entry of handwritten data, such as a signature, without use of an electronic tablet. In step S2-1, a user affixes a signature by means of moving a pen device 30 in midair. In step S2-2, camera means 20 photographs the pen device 30 and outputs the resultant image data. In step S2-3, coordinate computation means 22 determines coordinates of a pen tip of the pen means 30 on a screen on the basis of the image data (motion picture data), thereby determining signature data. In step S2-4, comparison verification means 40 compares and verifies the thus-determined signature data with reference data. If a similarity exists between the signature data and the reference data, there is output an authentication result showing "authentication of verification." Thus, personal identification can be effected on the basis of the signature data written by the user in midair.
