Topic: Good Health Pass - Paper Credentials
Start Time : May 19, 2021 10:59 AM

1. Welcome and Linux Foundation antitrust policy

2. Sync w/ Credentials Group

Creds group recommending two signatures; passes are already minimized and constrained to a particular context, they could be issued directly (a use case that has been brought up as necessary for some players)
BBS+ signature from issuer is different than BBS+ signature presented to verifier; if pass coming from directly from issuer, can they issue it so verifier can verify it?
Have not yet recommended how to store BBS+ in any format other than digital
Should there be a transformation from paper back to digital (what is resulting thing)?
- Digital representation of final pass (couldn't create a full BBS+ credential from paper version)
- Paper creds encoding in nuts and bolts; get something digital and convert it to paper, when paper scanned it converts to digital
- Distinction between passes and credentials; QR codes for both?
- ACTION: Creds group to take problem statement 7 and make recommendations for credentials and passes that talk about the transformation between the two and how to use safely; add note about if you have paper version of BBS+ credential you wouldn't share that directly it would need to be derived into a pass
