1. An abnormal data processing system that acquires a new data including time-series waveform signals from a detector that detects motion information in a finger tapping motion, which is an opening and closing motion of thumb and forefinger of one hand of a subject, and detects whether or not the new data is abnormal and processes the new data, comprising:
a storage unit that stores an individual-subject database (DB) in which data of an individual subject is accumulated;
an individual-subject DB divergence degree calculation unit that calculates an individual-subject DB divergence degree which is a degree of divergence of the new data from the individual-subject DB; and
a calculation unit that calculates the individual-subject DB divergence degree, using a number of data items in the individual-subject DB,
wherein it is determined whether or not the new data is abnormal on a basis of the degree of divergence, and
wherein the calculation unit uses an individual-subject DB reliability coefficient which increases as the number of data items in the individual-subject DB increases and weights the individual-subject DB divergence degree with the individual-subject DB reliability coefficient to calculate the degree of divergence.
