Risk profiles

Last updated: April 29, 2024

This topic describes how to use risk profiles to control iProov pass and fail authentication results.

About risk profiles

You can use risk profiles to indicate to iProov the risk tolerance for authentication attempts (enroll and verify). The iProov service always returns a binary pass or fail result. However, a risk profile impacts the way iProov applies thresholds to the biometric tests to change the likelihood that an attacker or imposter can pass.

Risk profiles enable you to balance security and usability. A more lenient profile can result in more fraudulent attempts being passed and a greater false accept rate. A more stringent profile can result in greater false reject rates of genuine users.

How are risk profiles calculated?

A risk profile is expressed in terms of the allowable False Match Rate (FMR) for the matching performance and the Combined Attack Presentation Classification Error Rate (CAPCER) that determines the estimated acceptance rate of attacks. While the FMR and CAPCER are fixed, iProov continuously optimizes for the corresponding False Non-Match Rate (FNMR) and Biometric Presentation Classification Error Rate (BPCER), which provide the optimal usability at the given risk tolerance.

Enable risk profiles

To enable risk profiles:

  1. Create a service provider.

  2. Send an email to Support with the {_service_provider_id}. See the email template below.

  3. Specify the required risk profiles (the maximum is three).

  4. The configured risk profiles are then included in the generate token REST API calls.
