Self‑Sovereign Identity (SSI)
Privacy
Decentralized identity model where users hold verifiable credentials and control disclosure.
Definition
SSI uses decentralized identifiers and credentials so individuals can store proofs (often in a wallet) and present selective information to verifiers. Privacy depends on minimizing linkability and over-disclosure.
In plain English
Decentralized identity model where users hold verifiable credentials and control disclosure.
Why this matters
Why it matters: SSI can reduce cross-service correlation and central tracking when designed with minimal disclosure.
Example
Example: Use different identifiers per relationship and disclose only required attributes (e.g., “over 18”).
