大和総研とレセプト、DID/VC技術を活用した自己主権型電子証明書サービスの提供に関する覚書を締結

株式会社大和総研と株式会社レセプトは、自己主権型電子証明書サービスの提供に関する業務提携の覚書を締結しました。

1.業務提携覚書締結の背景

In recent years, the risk of personal information leaks due to unauthorized access or cyber attacks has been increasing. In response to this situation, the Personal Information Protection Act requires that when a personal data leak occurs and there is a risk of harming an individual’s rights and interests, a report must be made to the Personal Information Protection Commission and notification must be given to the individual.

このような背景の中、個人情報漏えいリスクに対する危機感の高まりや、企業における個人情報管理負担の増大から、個人と企業の双方において、不要な個人情報のやり取りを避けたいというニーズが高まっています。

However, currently, even if you only want to confirm a person’s name, you must present a driver’s license or other identification document, resulting in the disclosure of unnecessary personal information. There are attempts to limit the scope of disclosure, such as by submitting copies of identification documents with blacked-out parts, but this creates other problems, such as the hassle of blacking out parts and making it difficult to verify their authenticity.

To solve this problem, Daiwa Institute of Research and Recept aim to provide a “self-sovereign digital certificate service.” With this service, information from identity verification documents is digitized and stored on the user’s smartphone, and the user can select and submit only the minimum amount of identity verification information that needs to be disclosed. In addition, blockchain technology allows information handlers to verify the authenticity of the information they receive. This reduces the workload associated with limiting the scope of personal information disclosure while ensuring authenticity, satisfying the needs of both those who provide and those who handle personal information.

As the core company of the Daiwa Securities Group’s digital strategy, Daiwa Institute of Research has been providing high-quality and highly reliable services, including core systems for securities operations, and promoting business model transformation using cutting-edge technologies such as blockchain and AI.

Recept is a startup specializing in DID*1/VC*2 technology with the mission of “Becoming a company that changes history.” Its flagship product, “proovy,” is an integrated platform that enables the issuance, verification, and management of digital certificates through wallets. Since its service release in March 2024, it has been adopted primarily by educational institutions and certification issuing organizations, and has become the second company in Asia to obtain EBSI (European Blockchain Services Infrastructure*3) international certification.

Now, by combining the secure system development technology and blockchain technology that Daiwa Institute of Research has cultivated in the financial industry with Recept’s knowledge and services in the DID/VC field, the two companies have decided to promote the development of a “self-sovereign digital certificate service.”

The two companies will engage in preferential negotiations to jointly develop a secure and convenient digital certificate service based on Recept’s “proovy.”

(2) 市場開拓とビジネスモデルの確立

両社は、電子証明書の認知度向上を目指し、新たな市場開拓を推進するとともに、業界標準となるビジネスモデルの確立を目指します。

1. DID（Decentralized Identifier）は、分散型デジタルIDを実現するための識別子です。デジタルIDにより、ユーザーはデジタル空間における自身のIDを安全かつ独自に管理することができます。関連するクレデンシャルは、ユーザーが管理するデジタルウォレットに保存され、情報の選択的な開示が可能です。ユーザー中心の分散管理により、組織や国境を越えたデジタルIDの相互運用性が向上し、より柔軟で安全なデジタルIDエコシステムの実現が期待されます。
2. VC（Verifiable Credentials）は、検証可能なデジタル証明書です。個人が自分のクレデンシャルを安全に管理し、必要な情報のみを選択的に受信者に提示することができます。受信者は容易に真正性を確認することができ、デジタル環境における安全な本人確認を実現します。
3. EBSI（European Blockchain Services Infrastructure）は、欧州委員会と欧州各国政府が共同で設立したブロックチェーン基盤。その目的は、EU全域で信頼性の高いブロックチェーンサービスを提供し、デジタルID、教育認証、社会保障、ビジネス取引など様々な分野での利用を促進することです。
