A method and an apparatus for authenticating user using biometric information. The apparatus authenticates the user by performing: generating a first feature vector from first biometric information of the user obtained by the biometric sensor and multiplying the first feature vector by a plurality of pseudo-random number (PRN) matrices, respectively; generating a query template based on an index of an element having a maximum value among elements of a result vector of the multiplication between the first feature vector and the plurality of PRN matrices; and performing authentication for the user by comparing the query template with a pre-stored reference template of a subscribed user.

Method and apparatus for authentication of user using biometric

A method and an apparatus for fingerprint recognition are disclosed. The apparatus for the fingerprint recognition may extract a plurality of fingerprint feature points from a fingerprint image and may predetermine a group among the plurality of fingerprint feature points. The apparatus for the fingerprint recognition may also calculate a ridge number between the first fingerprint feature points included in the group and may use the ridge number to generate a ridge count sequence.

Method and apparatus for fingerprint recognition

A face recognition based key generation apparatus controls a key generation model that is formed of a CNN and an RNN to be learned to generate a desired key having a consistent value by using sample facial images of a key owner and a PIN of the key owner as inputs, and the key generation model receives a facial image of the key owner and the PIN of the key owner, as inputs at a desired key generation time, and generates a key.
