Abstract: Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.

Abstract: Disclosed herein are an apparatus and method for managing personal information. The method includes a step in which a user terminal device registers the decentralized identification information of a user in a blockchain, receives the personal information of the user, stores the same in an endpoint for managing the personal information, and registers a personal information access policy for the personal information in a first server; a step in which the apparatus receives the decentralized identifier of the user, retrieves the decentralized identification information of the user, corresponding to the decentralized identifier, from the blockchain, and requests a personal information access token for accessing the personal information from the first server using the decentralized identification information; and a step in which the apparatus identifies the endpoint from the personal information access token, which is generated based on the personal information access policy, and retrieves the personal information from the endpoint.

Abstract: 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.

Abstract: There are provided a method and device for providing a security assistant service. In an embodiment of the invention, there is provided a device for providing a security assistant service in which a first terminal and a second terminal are included. The device includes the first terminal configured to generate information for requesting verification of an original plaintext to be signed (here, the information for requesting verification of the original plaintext to be signed refers to the original plaintext to be signed or a hash value of the original plaintext to be signed) and transmit an encrypted value in which the information for requesting verification of the original plaintext to be signed is encrypted and the original plaintext to be signed to the second terminal, and the second terminal configured to receive the original plaintext to be signed and the encrypted value, decrypt the information for requesting verification of the original plaintext to be signed by decrypting the encrypted value, display the original plaintext to be signed when the original plaintext to be signed or a hash value of the original plaintext to be signed matches the decrypted information for requesting verification of the original plaintext to be signed, receive a verification signal from a user, generate an original verification message (here, the original verification message refers to information indicating that the original plaintext to be signed is verified by the user and the information can be proved using a key held by the second terminal and verified using the key held by the first terminal) and transmit the original verification message to the first terminal.
