OpenID Foundation Opens Vote on Advanced Syntax for Claims Specification Relevant to Mobile Wallets

Why It Matters

Standardizing fine‑grained claim handling accelerates mobile wallet adoption and reduces privacy risk, giving regulators and enterprises a trusted protocol for credential exchange.

Key Takeaways

• Vote runs May 1‑15, 2026; approval advances ASC to Implementer’s Draft.
• Selective Abort/Omit lets apps suppress unwanted claims in responses.
• Transformed Claims enable derived data, like age verification, without raw data.
• Mobile wallets gain a uniform method for fine‑grained identity disclosure.

Pulse Analysis

The OpenID Foundation, the steward of the widely adopted OpenID Connect protocol, opened a formal member vote on May 1 for its Implementer’s Draft of OpenID Connect Advanced Syntax for Claims (ASC) 1.0. The two‑week voting window closes on May 15, and a positive outcome will promote the draft to the Implementer’s Draft stage, a key milestone that signals readiness for trial deployments and cross‑ecosystem interoperability testing. By moving the specification forward, the Foundation aims to give developers a standardized way to articulate complex claim requests, a need that has grown alongside the rapid expansion of mobile credential wallets.

ASC 1.0 introduces two powerful extensions: Selective Abort and Omit, which let a relying party define conditions under which specific claims are omitted, and Transformed Claims, which apply functions to existing attributes—such as converting a birthdate into an age‑verification result without exposing the full date. These mechanisms directly address privacy concerns in regulated sectors, where users must prove eligibility (e.g., legal age or enrollment status) without disclosing unnecessary personal information. Mobile wallet platforms that support digital driver’s licenses, verifiable credentials, and government IDs can now embed fine‑grained disclosure logic into a single, interoperable protocol.

The vote comes as the OpenID Foundation expands its conformance testing program for wallet and verifiable‑credential standards, including self‑certification for OpenID4VP 1.0 and OpenID4VCI 1.0. A successful ASC adoption will reinforce the ecosystem’s intellectual‑property‑protected licensing model, giving enterprises confidence to implement the spec at scale. For banks, insurers, and public agencies, the ability to request transformed or selectively omitted claims reduces compliance risk and streamlines onboarding flows. As cross‑border digital identity frameworks mature, ASC 1.0 is poised to become a cornerstone of the next generation of privacy‑preserving mobile identity solutions.
