Selfie Photo Comparison Overview

Selfie photo comparison, also known as biometric verification, is an identity verification method used across all Proof transaction types—Sign, Identify, Verify, and Notarize—where a real-time selfie is matched against a provided photo ID, serving either as the preferred verification method or as a fallback to knowledge-based authentication, with biometric verification accepted for notarizations in Michigan, Nevada, New York, and Pennsylvania.

The short answer: Selfie comparison (also called biometric verification) verifies a person's identity by comparing a real-time selfie to their provided ID. For more about identity verification methods, see the Identity verification overview.


How it works

First, the person verifying their identity:

  1. 1.Captures images of their photo ID (such as a driver's license).
  2. 2.Takes pictures of their face.

Next, the system or an agent compares these photos to confirm the person on the ID matches the person completing the transaction.
