Face Comparison

Face Comparison determines whether two facial images belong to the same person and returns a similarity score and a match or no-match result. In KYC verification, it compares the liveness selfie with the ID document photo. During the Face step, Face Comparison runs automatically after Liveness Detection.

How Face Comparison works

Face Comparison uses advanced biometric facial recognition to match the applicant’s liveness selfie against a reference image. Verification runs in three steps:

1. Feature Extraction: Detects faces in both images and converts them into numerical feature vectors;
2. Similarity Scoring: Compares these two numerical feature vectors and outputs a similarity score;
3. Comparison Result: Returns a match or no-match result based on a predefined threshold.
