The term SSI stands for:
Self-sovereign identity
SSI or Self-sovereign identity is a technology in identity management which allows individuals to manage their personal data themselves. While this is also possible by means of a centralized approach (e.g., by a financial service provider or the state), SSI are linked with a decentralized approach that follows the belief that individuals should keep the sovereignty over their data and on devices of their choice. Decentralized infrastruc- tures (DLT) are a suitable infrastructure for decentralized identifiers (DID). Since these infrastructures link transparency with anonymity, they are also solutions to contain money laundering (AML) or illegal transactions through KYC. Examples for SSI systems are Blockstack, Civic, Sovrin or uPort.
