1. User Control and Consent:
Digital identity systems must only reveal information identifying a user with the user’s consent.
2. Limited Disclosure for Limited Use
The solution which discloses the least identifying information and best limits its use is the most stable, long-term solutio.
The Law of Fewest Parties
Digital identity systems must limit disclosure of identifying information to parties having a necessary and justifiable place in a given identity relationship.
4. Directed Identity
A universal identity metasystem must support both “omnidirectional” identifiers for use by public entities and “unidirectional” identifiers for private entities, thus facilitating discovery while preventing unnecessary release of correlation handles.
5. Pluralism of Operators and Technologies:
A universal identity metasystem must channel and enable the interworking of multiple identity technologies run by multiple identity providers.
6. Human Integration:
A unifying identity metasystem must define the human user as a component integrated through protected and unambiguous human-machine communications.
7. Consistent Experience Across Contexts:
A unifying identity metasystem must provide a simple consistent experience while enabling separation of contexts through multiple operators and technologies.
