Biometric Identification Service
Documentation in progress. The new Biometric Identification Service documentation is being written. In the meantime, refer to the existing Lightweight Facial Identification Service (LFIS) documentation. For access and integration support, contact sales@innovatrics.com or request access to the Innovatrics Customer Portal.
Biometric Identification Service (formerly LFIS) is a high-performance, server-based biometric API for 1:N identification and verification using face and palm modalities. It is the path for centralized, large-gallery identification beyond the on-device 1:N limit (~1:50K). Built with cloud-native principles, it can be deployed on-premises or in the customer's cloud. Passive liveness detection is available as an add-on for both face and palm.
Inputs
The service accepts two kinds of input:
- Images — captured by the mobile or on-device capture components (for example DOT Auto-capture); the service performs detection, quality assessment, and template extraction server-side. This is the primary, most broadly compatible path.
- Templates — face/palm templates already extracted on the device by the SFE Toolkit, submitted directly for matching. Sending templates requires a compatible template version between the on-device SFE Toolkit and the service; otherwise submit images instead.
Capabilities
| Feature | Description |
|---|---|
| Detection & Quality Assessment | Automatic detection of faces and palms from incoming images, including quality assessment to ensure compliance with recognition thresholds. |
| 1:N Identification | Searches a live-captured image or extracted template against a configurable watchlist and returns the most likely match with a confidence score. |
| Passive Liveness Detection | Detects presentation attacks without requiring user interaction, for both face and palm modalities. |
| Watchlist Management | Enroll, update, and remove biometric data via API. Supports dynamic watchlist creation and unlimited watchlists within the standard database size. |
| RESTful API | Supports real-time matching, asynchronous queries, and secure communications (TLS, authentication tokens). Integrates with web, mobile, or embedded client applications. |
| Cloud-ready Deployment | Deployable as a local server component or scaled in Kubernetes/Docker-based cloud infrastructure. |
Supported platforms
| Platform | Architecture |
|---|---|
| Linux | x86_64 |
