Face Match: Selfie vs ID Photo

Confirm the user owns the ID. Compare selfie or liveness image to the document photo and get a match score and result.

Face Match is a biometric comparison check that determines whether a selfie or live image matches the photo on a government-issued ID. It’s a critical step in confirming document ownership and detecting impersonation attempts during onboarding, account recovery, or high-trust actions.

Dojah’s face match engine compares facial embeddings from two sources:

• A selfie or liveness-captured image

• A document photo (from ID, passport, or license)

The system returns a match result, confidence score, and fallback signals to guide your decision flow.

How it Works

1. Image Capture

   You capture two images:

   • A selfie (either passive image or from a liveness session)
   • A document photo, usually auto-extracted from a submitted ID
2. Face Matching

   Both images are compared using deep-learning models trained to detect fraud, obstructions, and minor facial changes (e.g., hairstyle, glasses).

3. Scoring & Result

   The system returns a boolean match result and a confidence score between 0 and 100. The confidence threshold defines what is considered an acceptable match.
