My colleague Gertjan De Mulder is presenting the work on using #VerifiableCredentials in #Solid pods with #LinkedDataNotifications at the SDS Workshop! In this work, the proof of a credential is stored in Solid pods to allow proving if a patient has a medical subscription to buy certain medication or proof that a job applicant has a diploma or skills for the job they are applying to.

At our recent AC meeting in Hiroshima, Japan , Leonard Rosenthol, of Adobe, introduced the work of the Coalition for Content Provenance and Authenticity (C2PA).

The C2PA work leverages W3C standards and aims to develop technical specs for widespread content provenance and authenticity, allowing users to trace media origins. #VerifiableCredentials, #WebAnnotations,

Snapshot of the video recorded talk of Leonard Rosenthol, presenting what the C2P4 and Content Credentials are about: "The Coalition for Content Provenance and Authenticity (C2PA) is a Linux
Foundation Joint Development Foundation project whose mission is to
develop technical specifications that can establish content provenance and authenticity at scale to give publishers, creators, and consumers the ability to trace the origin of media."

Securing Verifiable Credentials using JOSE and COSE is a @w3c #CandidateRecommendation !#timetoimplement
https://www.w3.org/TR/vc-jose-cose/

#VerifiableCredentials enhance trust, privacy, and control in digital interactions by enabling owners to manage how their information is shared and verified. This specification outlines how JSON Web Tokens (JWTs) can secure #VerifiableCredentials using JOSE and COSE.

Feedback is welcome in #GitHub: https://github.com/w3c/vc-jose-cose/

www.w3.orgSecuring Verifiable Credentials using JOSE and COSEThis specification defines how to secure credentials and presentations conforming to the Verifiable Credential data model [VC-DATA-MODEL-2.0] with JSON Object Signing and Encryption (JOSE), Selective Disclosure for JWTs [SD-JWT], and CBOR Object Signing and Encryption (COSE) [RFC9052]. This enables the Verifiable Credential data model [VC-DATA-MODEL-2.0] to be implemented with standards for signing and encryption that are widely adopted.

Data Integrity BBS Cryptosuites v1.0 has just been published as a #w3c Candidate Recommendation #timetoimplement !

https://www.w3.org/TR/2024/CR-vc-di-bbs-20240404/

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).

See also the "BBS Cryptosuite v2023 Explainer": https://github.com/w3c/vc-di-bbs/blob/main/EXPLAINER.md

www.w3.orgData Integrity BBS Cryptosuites v1.0This specification describes a Data Integrity Cryptosuite for use when generating digital signatures using the BBS signature scheme. The Signature Suite utilizes BBS signatures to provide selective disclosure and unlinkable derived proofs.
