This guide shows how a combination of the following can provide various levels of assurance around proving an identity:

  • the breadth of evidence
  • the strength of the evidence
  • the validation and verification processes carried out
  • a history of the user’s activity

The guidance aims to:

  • provide organisations with an understanding of the capabilities they will need to be able to demonstrate in order to perform identity proofing
  • provide information to independent assessment organisations so that benchmarks or profiles can be developed to support the independent assessment and certification of organisational and technical capabilities
  • establish a common framework establishing requirements for the validation and verification of the identity of individuals
