Frequently Asked Questions
Common developer queries about integrating the Face Liveness API.
1. What is the Face Liveness API?
This API allows businesses to compare two facial images to determine if they belong to the same person. It is widely used for digital onboarding, e-KYC, and multi-factor authentication by Livenessing a live selfie against a government ID photo.
2. How accurate is the facial recognition?
Our API uses state-of-the-art deep learning models trained on diverse datasets to ensure high precision. It maintains industry-leading False Acceptance Rates (FAR) and False Rejection Rates (FRR), ensuring reliable Livenessing even with variations in lighting or expression.
3. Does it include Liveness Detection?
Yes, our Face Liveness API includes integrated liveness detection to prevent spoofing attacks. It can distinguish between a real human face and a high-resolution photo, video replay, or a 3D mask.
4. What image formats are supported?
The API supports standard image formats including JPEG, PNG, and WebP. Images can be provided via public URLs or as Base64 encoded strings within the JSON request payload.
5. Can it handle low-quality ID photos?
Our engine includes automatic image enhancement and noise reduction features. It is specifically optimized to extract biometric features from scanned government IDs, even if the original document has minor wear or graininess.
6. Is this API compliant with data privacy laws?
Absolutely. We adhere to strict data privacy regulations. Biometric data is processed in real-time and we do not store facial templates or images unless specifically requested by the client for audit purposes.
7. What is the typical response time?
Our Face Liveness API is built for speed, typically returning a Liveness score and verification result within 200–500 milliseconds, ensuring a frictionless user experience during onboarding.
8. How is data security handled?
We utilize AES-256 encryption for all data at rest and TLS 1.3 for data in transit. Our infrastructure is hosted in SOC2 compliant data centers to ensure the highest level of security for sensitive biometric information.
