Abstract
A method according to an embodiment includes transforming registered data on a user, which is encrypted with an encryption algorithm that enables a calculation of a Hamming distance in an encrypted state, such that a calculation result of a Hamming distance between the registered data and verification data that is encrypted with the algorithm includes a Hamming distance between the verification data and the user's registered data and a Hamming distance between the verification data and a random vector generated from the user's registered data; calculating a Hamming distance between the verification data and the registered data; and determining whether the input verification data is false based on a result of comparison of each of the Hamming distance between the verification data and the user's registered data and the Hamming distance between the verification data and the random vector included in the calculated Hamming distance with a threshold.
