1. A system, comprising:
a user terminal, comprising at least one hardware processor, that acquires an object fingerprint of an item and biometric information of an owner of the item; and
a plurality of ledger nodes that provides an electronic bulletin board,
wherein the user terminal writes an ownership right certificate including the object fingerprint of the item and the biometric information of the owner on the electronic bulletin board;
wherein the system further comprises a viewer terminal that reads the ownership right certificate corresponding to a first transaction ID from the electronic bulletin board,
wherein the viewer terminal performs an object authentication using an object fingerprint acquired from an item to be verified and an object fingerprint described in the ownership right certificate, performs a biometric authentication using biometric information acquired from a person to be verified and biometric information described in the ownership right certificate, and determines that the item and the person to be verified are legitimate when the object authentication and the biometric authentication are successful.
