Identity Assurance Level 1.5 (DRAFT)

This document aims to define some Identity Assurance Level(IAL) between NIST Digital Identity Guidelines IAL 1 and 2. This alternative level was created to serve public health scenarios. The 1/5 level is designed to show that "some real world corroboration of identity" is given, but it does not meet NIST's IAL 2 standards in some way. This document is not published by NIST. This is a working draft document. Comments and collaboration welcome. Use the Issues and Pull request features on Github to suggest changes.

Criteria for using IAL 1.5:

Any of the following are acceptable forms of proof of identity for an Identity Assurance Level 1.5 designation.

• An in-person or virtual encounter where some corroborating evidence is provided. Examples include non-photo identification such as
  insurance card, a Medicare/Medicaid card, a utility bill, etc.
• 2nd party identity attestation. "I, Bob, know Alice to be Alice."
• Photo identification issued by a state or federal government, but does not meet the IAL2 validation requirements for "STRONG".

Implementatation Guidance

If requirements are met for IAL 2, then IAL 2 should be used instead of IAL 1.5.
