Self Sovereign Identity (SSI) is an umbrella term well-detailed by Christopher Allen, and inspired by many in the Identity community before him, in his 2016 blog post: The Path to Self-Sovereign Identity, which identifies Ten Principles of Self-Sovereign Identity:
- Existence. Users must have an independent existence.
- Control. Users must control their identities.
- Access. Users must have access to their own data.
- Transparency. Systems and algorithms must be transparent.
- Persistence. Identities must be long-lived.
- Portability. Information and services about identity must be transportable.
- Interoperability. Identities should be as widely usable as possible.
- Consent. Users must agree to the use of their identity.
- Minimalization. Disclosure of claims must be minimized.
- Protection. The rights of users must be protected.
