Biometric Identity Verification for High-Stakes Exams

Project Overview

CanWill Athenaworks partnered with a parent company initiative to engineer a secure, scalable online examination platform designed for high-stakes recruitment across District Central Co-operative Banks and similar institutions. The product was purpose-built to eliminate candidate impersonation and ensure audit-ready, Aadhaar-compliant identity verification at scale.

The system integrates dual-layered user validation via Aadhaar OTP during registration and biometric fingerprint scanning during on-site examination, providing end-to-end verification assurance.

Tech Stack

  • ReactJS (frontend)
  • C#.NET (backend)
  • MS SQL (DB)
  • Azure (cloud)
  • UIDAI APIs (OTP + Biometric)
  • MFS110 RD SDK
  • SendGrid
  • Razorpay

Client Background

The client operates within India’s cooperative banking sector, serving District Central Co-operative Banks that run recruitment exams across multiple dispersed centers. As a regulated financial body, the organization answers to oversight from the Commissioner for Cooperation and must meet UIDAI’s compliance requirements for any Aadhaar-linked identity infrastructure, including AUA/KUA registration.

Recruitment fraud had become an operational and reputational liability for the client, with no standardized way to confirm candidate identity across locations. The organization approached CanWill Athenaworks without a pre-existing BRD or UI/UX framework, requiring a build-from-scratch engagement rather than an integration into existing systems.

Strategic Takeaways

  • Secure design without a BRD: Required agile thinking and deep domain knowledge.
  • Partnerships matter: Working with trusted UIDAI API providers enabled faster compliance.
  • User training drives adoption: Empowering exam center staff minimized biometric onboarding issues.
  • Real-world feedback fuels evolution: Deployment under pressure drove rapid iteration and continuous improvement.

The Challenge

Recruitment fraud—particularly candidate impersonation—posed a significant threat to credibility and operational integrity. Organizations lacked the infrastructure to verify user identity securely and consistently across dispersed exam centers.

Key Pain Points:

  • No initial BRD or UI/UX framework.
  • Identity fraud through impersonation.
  • Unpredictable UIDAI API response times.
  • Non-compliance risk due to lack of AUA/KUA registration.
  • Manual candidate attendance tracking creating delays and inefficiencies.

The Solution:

CanWill Athenaworks’ Application Engineering team delivered a robust, modular product that combined security-first architecture with user-centric design.

Key Components:

  • Candidate Registration Portal: Uses Aadhaar OTP via UIDAI’s secure API for registration-time validation.
  • Examination Portal: LAN-based, offline-capable system with real-time biometric authentication using Mantra MFS110 fingerprint devices.
  • Admin Console: Dynamic attendance sheet generator reduced manual collation from days to hours.

Data Handling & Privacy Compliance:

In line with UIDAI regulations, the system performs all Aadhaar OTP and biometric validations as ephemeral, runtime operations. Biometric and personally identifiable information is never stored—locally or in the cloud. The system receives real-time identity validation data strictly for cross-verification against registration details, without persisting any sensitive user data. This approach ensures full compliance with UIDAI’s stringent data privacy standards and reinforces the product’s integrity in high-stakes environments.
