Assurance framework

REFEDS Assurance Framework

Reliability is modelled via three individually addressable components

  • Identifier uniqueness (uniqueness and type of identifier)
  • Identity assurance (quality of the identity assurance process)
  • Attribute assurance (quality of attribute values)

A controlled vocabulary is used to describe the three components. The corresponding information is transferred via the eduPersonAssurance attribute. Service providers can select the details relevant for the respective service.
