An anonymous credential authentication system receives an anonymous credential signature value indicating that setting proposition information using a credential is satisfied from a user device that has been issued the credential combined with multiple pieces of attribute information constituting personal information, generates signer authentication information that confirms a signer of the anonymous credential signature value using an opening key, and outputs the signer authentication information.

Anonymous credential authentication system and method thereof

A method and an apparatus for providing a service using a kiosk by a service providing server by performing the steps of: receiving a device list of at least one kiosk having an ability to provide the service among a plurality of kiosks registered in a blockchain from a kiosk server; authenticating a first kiosk through a smart contract function embedded in the blockchain when a user requests the service through the first kiosk and determining whether the first kiosk is included in the device list; and providing the service to the user when the first kiosk is authenticated by the smart contract function and is included in the device list are provided.

Method and apparatus for providing service using kiosk

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.

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.

Method and apparatus for key generation based on face recognition using CNN and RNN

The present invention provides an apparatus for sharing a user control enhanced digital identity that allows a user to have all controls and control the flow of identity sharing on the user basis when the user shares user's personal information. According to the present invention, a user can decrease infringement of personal information due to illegal usage of the personal information by allowing a user to control usage of user's personal information and prevent the user's personal information from being carelessly used. Further, a provider that provides the services can efficiently associate the services between providers.
