A transaction information managing system including a plurality of servers and at least one third-party server, wherein the plurality of servers are configured to create, when transactions using the budget of the public organization occurs, a block based on transaction information of the transactions, add the block to the block chain, and share the block chain and the at least one third-party server is configured to perform a mathematical operation to enhance the reliability of the block chain, and a method for managing the transaction information are provided.

Apparatus and system for managing transaction information of public organization using blockchain technology

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.

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.
