Biometric information device, distributed ledger identity verification system, and program

摘要

The present invention relates to IoT (Internet of Things), and its technical field corresponds to G06Q or the like in IPC classification, which facilitates prevention of spoofing and prevention of data tampering. An object of the present invention is to provide a distributed ledger identity verification system, a distributed ledger identity verification method, a program, a biometric information device, and an identity verification device that can be easily performed. SOLUTION: A distributed ledger identity verification system that performs identity verification by using a plurality of biometric information devices in a city and a distributed ledger causes the biometric information device to acquire biometric information of a target person. , The biometric information device is made to analyze the biometric information to extract the characteristic amount of the target person, and the target person is the same person as the user registered in advance from the characteristic amount in the biometric information device. If it is determined that the biometric information device is the same person, the biometric information device is caused to extract the ID of the user, and the biometric information device acquires the ID and the time when the biometric information is acquired. And the position are recorded in the distributed ledger, and the identity is confirmed based on the route information based on the time and the position recorded in the distributed ledger.
