摘要
A method of adjusting reference information for biometric authentication, comprises storing the reference information including reference biometric data and threshold values corresponding to a plurality of users, respectively, obtaining biometric data of a user by inputting biometric information of the user, calculating a matching ratio of the biometric data with the reference biometric data of each of the users, respectively, comparing the matching ratio of each of the users with the threshold value of each of the users, respectively, determining which of the matching ratios exceed the corresponding threshold values and adjusting the threshold values which are exceeded by the corresponding matching ratios so that all the matching ratios but the highest matching ratio become lower than the adjusted threshold values, respectively.
