We describe a decentralized protocol for "proof-of-contact" in zero knowledge where a person can publish a short cryptographic proof attesting to the fact that they have been infected and that they have ...
More importantly, we describe how to compose these proofs to support broader functionality such as proofs of nth-order exposure which can further speed up automated contact tracing. ...
We propose a new protocol for privacy-preserving contact tracing that does not suffer from these limitations. ...
