| Intrinsic | Extrinsic |
|---|---|
| Likes, dislikes, personality, physical appearance, etc. | Credentials, documents, artifacts, etc. |
| i.e. How we identify ourselves | i.e How others identify us |
Can you think of any way how are these identities expressed digitally?
"Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control of their digital identities." [1]
Agents
Verifiable Credentials
Decentralized Identifiers
Blockchains and Verifiable Data Registries
Cryptographically-protected equivalent of paper credentials
Carried by the holder on a smartphone or other computing device
Not on a blockchain
Cryptographically-protected data that proves that you are you!
Verify user identity to process payments
Issue digital government documents such as birth certificate, driver's license, etc.
Issue and verify medical documents such as exemptions, vaccination cards, etc.
Implement user authentication and management
Can you think of something else?
