DIDVC

DIDVC is a concept for applying decentralized identity principles to video conferencing. It envisions using Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to manage participant identities, access rights, and trust relationships across conferencing platforms. The goal is to increase user control, portability, and interoperability while reducing reliance on centralized identity providers.

DIDVC builds on the W3C standards for DIDs and VCs. Under this approach, each user or organization can create a DID, publish it in a decentralized method (such as did:key, did:web, or did:peer), and attach verifiable credentials that attest to attributes like organization affiliation, role, or meeting permissions. A DID resolver is used to resolve identifiers and verify credentials, while revocation mechanisms allow credentials to be withdrawn when necessary. The signaling layer and media path can be secured with end-to-end encryption, with identity information limited to what is strictly necessary for access control and auditing.

Architecturally, DIDVC emphasizes lightweight credential exchange during meeting enrollment, policy-based access control, and transparent audit trails for compliance. It supports cross-platform interoperability by avoiding vendor-specific identity ecosystems and enabling portable trust material. Privacy-preserving techniques, such as minimal disclosure credentials, may be employed to reduce exposure of unnecessary data.

Benefits of DIDVC include stronger participant authentication, Improved access control across different platforms, and greater user sovereignty over identity data. Challenges involve key management, revocation reliability, onboarding complexity, cross-domain interoperability, and ensuring performance remains suitable for real-time communication. As a concept, DIDVC remains under exploration, with ongoing work to align it with existing decentralized identity standards and diverse conferencing environments.
