Agenda:

10:00–10:05 Opening Remarks

10:05–11:00 Governance of Digital Credentials Shigeya Suzuki (Keio University) Naohiro Fujie (ITOCHU Techno-Solutions)

Portable digital credentials such as Verifiable Credentials and related technologies are attracting considerable attention. However, using such digital credentials for KYC and similar processes at financial institutions, for example, entails a variety of considerations. Drawing on the latest developments in the EU, Europe, and the United States, the Keio Research Institute at SFC and ITOCHU Techno-Solutions Corporation have conducted joint research into the management requirements and governance of digital credentials. This session will introduce the jointly published discussion paper, “Management Requirements Based on the Use Cases of Digital Credentials,” and examine the issues that must be addressed when applying digital credentials to financial services and other areas in the future.

11:00–11:55 Open Banking and FAPI 2.0 Takahiko Kawasaki (Authlete)

In the middle of the 2010s, the United Kingdom launched an open banking policy primarily intended to promote competition in the financial industry. This policy established mechanisms that allow computer programs to access financial services, leading to the emergence of a wide range of financial services and making people’s lives more convenient. This open banking movement has now spread around the world, supported technically by a global standard specification called FAPI. FAPI itself reached a major milestone this year when, in month 2, the final version of FAPI 2.0 was approved. In this session, Authlete, home to authors of the FAPI 2.0 specification, will explain open banking and FAPI 2.0.

VCはほとんどやってこなかった

Kristina (DCP WG議長) がSelective Disclosureを諦めようとしていたときに、今で言うSD-JWTみたいにすれば諦めずにすむだろうと言ったくらい。

WHY? 

→ 自分が引退するまでに終わらないと思った〜だから若い人たちに任せる

ただVC的なものと無縁だったわけではない

FAPIのFirst Use Caseの一つが、銀行が行った本人確認に基づいてID Token+OIDC4IDAでQualified Certificateを出す

Linkability ということについて Pascal Paillier といっしょに整理→ ISO/IEC 27551 Requirements for attribute-based unlinkable entity authentication

Privacy Notice and consent (ISO/IEC 29184)

Privacy Framework (ISO/IEC 29100:2024)

これらはVCエコシステムを考える際にも重要であると考えている

最近気になること

Verifier が要求してきているものが正当か?(溜まったものをごっそり抜かれる問題)

そのWalletは信頼できるのか?(安全か、盗聴していないかなど)

Wallet爆発とWallet/Credential Selection 問題

EU: 2026年に間に合うのか??

    12:00–12:40 Networking Reception
