Identity Resolution

What is Identity Resolution?

The process of connecting disparate data points to a single individual across different data sources and devices, raising privacy implications.

Privacy and Data Protection

Each of these is named in at least one of the same controls as identity resolution. The number is how many controls name both.

What the standards actually require on identity resolution

Requirements naming identity resolution across 2 standards, quoted from the control text.

Implement IAL2 identity proofing per NIST SP 800-63A Chapter 5 covering remote (Section 5.3.2) and in-person (Section 5.3.3) options.

NISTSP63-3 · IAL2 Remote and In-Person Identity Proofing

Conduct identity proofing per NIST SP 800-63-4 Volume A (Identity Proofing and Enrollment). Collect identity evidence per Section 4.3 (evidence quality tiers FAIR + STRONG + SUPERIOR) appropriate to IAL level.
