India’s UIDAI rolls out AI-enabled biometric deduplication and document verification platform

UIDAI has deployed an advanced platform that uses AI-enabled models to improve biometric deduplication, the process of ensuring that each resident has a unique identity record, by checking fingerprints, facial images and iris scans against the entire Aadhaar database.

The authority describes this system, developed with the International Institute of Information Technology, Hyderabad, as an ‘Invisible Shield’ that can perform billions of computations efficiently at a population scale, running on high-performance inference infrastructure such as NVIDIA DGX systems to enhance accuracy and speed nationwide.

In addition to biometric matching, the platform incorporates AI-based document metadata extraction and verification to curb enrolment fraud, using secure APIs (e.g. DigiLocker) for source-of-truth checks against submitted documents.

The system is already being rolled out in several states. It is expected to expand across India in the coming months, boosting service quality, reducing turnaround times for Aadhaar enrolment and update transactions, and reinforcing trust in the digital identity infrastructure.

The initiative is part of a broader push to leverage AI for fraud detection and identity assurance at a national scale. It comes amid ongoing efforts by UIDAI to modernise authentication processes as biometric and AI-based systems evolve.
