User verification of privacy commitments without cryptographic expertise

Develop practical mechanisms that allow users without cryptographic expertise to verify that the privacy commitments of personhood credential issuers and service providers—such as unlinkability and minimal disclosure—are being upheld in operation.

Background

PHCs rely on cryptographic assurances to preserve privacy and unlinkable pseudonymity. The authors emphasize that ordinary users will need ways to validate that issuers and service providers are honoring these commitments without possessing specialized technical knowledge, to sustain trust, adoption, and accountability.
