Abstract
The present invention provides a detection apparatus, an input apparatus, an individual identification apparatus, and a recording medium that utilize information about users' bodies which disables the fraud of impersonating authorized users and is extremely difficult to forge and is obtained without giving the users a sense of inhibitions, without restraining their bodies during use, and independent of their mental states and health. A FIFO memory outputs, as one set of features, a total of 60 voltage values, which are broken down as 20 voltage values sampled every 12.5 ms (80 Hz) before the instant when timing is inputted at the peak position of an amplitude waveform signal generated by one click operation, 39 voltage values sampled every 12.5 ms after the instant, and a voltage value at the peak, and a CPU calculates a feature vector and a feature matrix for individual registration, stores them as personal data in a RAM, and identifies one set of features newly inputted, based on the personal data stored in the RAM.
