These capabilities are needed for creating, storing, presenting, and verifying user-controlled credentials among other things: DataMin is one of three mitigations against privacy threats in RFC6973, it is featured in article 5, 25 of the GDPR, the USA Privacy Act of 1974 and often appears in FIPPs. This group's goal is to standardize D&S techniques for the Verifiable Claims work (to be used in Blockchain systems supporting self-sovereign identity), an official work item of the W3C Credentials Community Group. Some topics we plan to address include Merkle trees for redaction, Progressive disclosure, CL Signature schemes (Camenisch-Lysyanskaya), ZK (zero knowledge) protocols such as Fiat-Shamir, ZK Snarks and Starks; also commercial providers such as Qredo.
