Configurable Thresholds

You can customize security levels by setting different thresholds for face matching scores. For example:

Face Match Thresholds

These thresholds can be adjusted based on your risk tolerance and security requirements.

How It Works

Image Preparation

Different workflows handle image selection in unique ways:

  • ID Verification Based Workflow

    • Automatically selects best quality image from liveness check
    • Pairs selected image with photo from ID document
    • Ensures consistent quality between both images

  • Biometric Authentication Based Workflow

    • Takes new live photo from user
    • Retrieves stored reference photo from previous approved liveness check
    • Compares images to confirm identity

  • Face Match API

    • Accepts direct upload of two images
    • Requires one live capture photo
    • Requires one reference photo for comparison
    • Validates image quality before processing

All images undergo preprocessing:

  • Resolution and lighting normalization
  • Face detection and alignment
  • Image quality enhancement
  • Strict quality validation checks

Face Matching

  • Compares the verified live image and the ID document photo
  • Analyzes 68 facial landmarks for precise alignment
  • Generates a similarity score from 0-100%
  • Applies configured thresholds for automated decisions

Result Processing

  • System applies your configured thresholds
  • Automatically approves, declines, or flags for review
  • Results available via API, dashboard, or webhooks
  • Detailed metrics and confidence scores provided
