# Selfie Verifications

> Verify that a live person is present and compare their face with an identity document.

A Selfie Verification answers the question "Is the individual present during the transaction?". This is especially useful when combined with a [Government ID Verification](/api-reference/verifications/government-id-verifications) to associate the face of the government issued id to the individual present.

The main goals of Selfie Verifications are to ascertain the following:

1. Face Image Quality

   1. Poses - Determine whether an individual is properly facing towards the camera
   2. Quality - Determine whether the image's resolution, lighting, and blur is sufficient for accuracy
   3. Obfuscation - Determine that an individual's portrait is not obfuscated by glasses, hair, or other items

2. Face Comparison
   1. Determine whether the individual matches a claimed individual

3. Face Liveness
   1. Determine whether the submission contains features that are indicative of a spoof

4. Age Estimation
   1. Determine whether the perceived age of the individual falls within the configured age range

## Selfie Capture Types

1. Center only - Only one portrait of the individual facing the camera is captured

2. Center and profile - Three portraits are captured, with the individual facing left, center, and right of the camera

## Product Versions

Selfie Verifications are versioned per component. Match, Liveness, and Age are released independently, so a Selfie Verification references one version of each.
