De-duplication Services

Biometric De-duplication is at the heart of any large scale Identity Management System as it ensures that a subject is not registered more than once and ensures one subject – one ID. The de-duplication services from 4Gid are built around 4G’s Multi-modal Biometric Platform that is highly scalable, algorithm agnostic and supports a flexible architecture. The platform is built on the experience of delivery some of the world’s largest and fastest Biometric Identification and De-duplication projects. The system provides choice to the clients to from technologies and algorithms depending on the application and desired performance parameters.

The De-duplication System is capable of performing demographic de-duplication, fingerprint de-duplication, face de-duplication, Iris de-duplication and Multi modal de-duplication. The system also supports manual adjudication of matches found by the system to identify false matches if any. Biometric quality measurement before de-duplication is another most important aspect of the system that ensures a continuous improvement process by providing feedback to the enrollment agency about the quality of their data. The system is designed for continuous improvement in throughput and accuracy.
