At the @w3c member meeting in #Hiroshima 🇯🇵, Leonard Rosenthol, Adobe, introduced the work of the Coalition for Content Provenance and Authenticity (C2PA) that leverages W3C standards (#VerifiableCredentials, #WebAnnotations, etc.).
C2PA aims to develop technical specs for widespread content provenance and authenticity, allowing users to trace media origins.
This specification describes how to generate digital #signatures for ensuring the authenticity and integrity of #VerifiableCredentials using the BBS signature scheme (👀 BBS is the acronym of its creators: Boneh, Boyen and Shacham).
