His work focuses on verification methods and attribute information conversion, showcasing his expertise in decentralized identifiers and credential verification.

Latest Patents

Yamaoka's latest patents include a verification method and an information processing apparatus. This apparatus acquires a first verifiable credential (VC) that proves the validity of attribute information of a holder through a first signature verifiable by the verification procedures of a first decentralized identifiers (DID) infrastructure. Additionally, it acquires a second VC that proves the validity of the attribute information of the holder through a second signature verifiable by the verification procedures of a second DID infrastructure. The apparatus then verifies the second signature contained in the second VC and transmits a verification request for the first signature contained in the first VC to a verification device. This device is capable of verifying the first signature by the verification procedures of the first DID infrastructure, ultimately acquiring verification results of the first signature.

Another notable patent is for an attribute information conversion device, which includes a memory and a processor. This device issues first and second access information linked to each other in response to a request for conversion from attribute information of a first type to a second type. It performs the conversion of the acquired attribute information and outputs the converted information to a terminal that has made access through the second access information.
