Good Health Pass compliant implementations must meet baseline security and privacy requirements that enable holders to maintain full control of their personal data.

Terms of Reference

All stakeholders in the Good Health Pass Collaborative digital trust ecosystem need to be confident in the security and privacy protections that the ecosystem enforces. In some jurisdictions, these protections are already required by existing data protection regulations; in other cases, governance authorities may seek to pass new legislation to enshrine them in law.  

To be consistent with the Good Health Pass principles, it is anticipated that Good Health Pass solutions will need to be built on a decentralized identity architecture that places an emphasis on privacy and personal data control. Such systems seek to put the user in control of their personal identity data – including health attributes – which they can selectively disclose for a specified purpose and duration. Such systems stand in contrast to centralized models, which amass and store large amounts of personal data that is under the primary control of the aggregator.

For Good Health Pass systems, the issuance, holding, presentation, and verification of digital health credentials must – at a minimum – comply with applicable regulations requiring:

Of particular importance with digital health credentials are privacy-preserving identifiers. This topic is discussed at length in the W3C Decentralized Identifiers (DIDs) Core 1.0 Specification. Specific DID methods support privacy-preserving identifiers that can provide the benefits of cryptographic verifiability without correlatability.
