Self-Sovereign Identity (SSI)
An identity model where the individual owns and controls their credentials without centralised issuers — the natural extension of key sovereignty.
Definition
An identity model in which the individual owns, controls, and presents their own identity credentials without dependence on any centralised issuer or verifier. SSI leverages decentralised identifiers (DIDs) and verifiable credentials to shift the power of identity attestation from institutions to the individual. In CLAVI's framework, self-sovereign identity is the natural extension of key sovereignty: if you control your cryptographic keys, you control the proofs that constitute your digital self.
