Abstract
A data comparison apparatus includes a cross-correlation table storing unit for storing degrees of match calculated for all possible combinations of two registered data, as a cross-correlation table, a comparison processing unit for comparing a currently-read registered data with an incoming data to be compared to calculate the degree of match between them, a comparison determination unit for comparing the calculated degree of match with a threshold value to determine whether there is a match between the currently-read registered data and the incoming data, and for forcedly finishing a further comparison process for remaining registered data if there is a match between the currently-read registered data and the incoming data, and a registered-data reading control unit for determining one registered data that is to be read next out of the registered-data storing unit, using the calculated degree of match and the cross-correlation table.
