Face comparison helps you determine whether two submitted images likely belong to the same person.

​
Best For

  • Identity confirmation after BVN, NIN, or document retrieval
  • Fraud reduction
  • Manual-review support

​
What You Submit

You submit:
  • source_image
  • target_image
These can represent a live selfie, stored customer image, or document-linked image depending on your flow.

​
What You Get Back

The endpoint returns a similarity score.

​
How To Use It

  • Define an internal threshold for accept / review / reject
  • Use higher thresholds for higher-risk actions
  • Combine with liveness when you need stronger anti-spoof protection
Face similarity should support a broader identity decision, not replace core identity-number or document verification by itself.
