Decentralized identity system
A decentralized identity system is an identity model in which individuals control their credentials and selectively share identity information without relying on a single central authority.
Authorization in Action
Self-sovereign identity is an identity model in which individuals control and manage the sharing of their identity information.
- How it is used
- Shifts identity control from central providers to individuals and uses portable credentials to improve authorization across organizational boundaries.
- How deep it goes
- Explains credential issuance, wallet storage, cryptographic verification, relying parties, trust frameworks, privacy, and authorization integration.
- Examples
- Uses government identity checks, university transcripts, contractor access, supplier trust, professional authority, and emergency access as concrete scenarios.
- What you can do after
- Apply verifiable credentials to authorize external users without creating every account or importing every external identity record.

- How it is used
- Positions identity control and selective disclosure within privacy-centric marketing and privacy-aware data use.
- How deep it goes
- Defines the model and its privacy rationale but does not explain credential protocols, governance, or implementation.
- What you can do after
