Abstract: An information processing apparatus acquires a first verifiable credential (VC) that proves the validity of attribute information of a holder by a first signature verifiable by verification procedures of a first decentralized identifiers (DID) infrastructure and a second VC that proves the validity of the attribute information of the holder by a second signature verifiable by verification procedures of a second DID infrastructure. Next, the information processing apparatus verifies the second signature contained in the second VC by the verification procedures of the second DID infrastructure. Further, the information processing apparatus transmits a verification request for verifying the first signature contained in the first VC to a verification device capable of verifying the first signature contained in the first VC by the verification procedures of the first DID infrastructure, and then acquires, from the verification device, verification results of the first signature contained in the first VC.
