Self-Sovereign Identity (SSI) is an emerging philosophy that allows you to determine where your data is stored and how it’s used. SSI is implemented through something called verifiable credentials, which are tamper-proof digital credentials that can be verified cryptographically through a machine. Verifiable Credentials are digitally signed by the issuing authority and encrypted by the holder's private-public key pairs. The issuer generates a VC, digitally signs using its private key, and encrypts the data using its public key. The holder can choose to save VC in a custodial wallet or another decentralized wallet.
