This enterprise-grade biometric authentication system processes millions of daily sessions with advanced security measures, ensuring compliance with banking regulations and providing seamless user experience.
Challenge
The bank required a new authentication layer to process millions of biometric logins daily across web and mobile platforms. The system had to ensure security, compliance, and uninterrupted operation — all within a containerized, distributed environment.
Our Approach
We developed independent microservices for user authentication, session tracking, and document processing, connected via asynchronous message queues. Every component was deployed as a Docker container, managed through Kubernetes clusters for maximum reliability and failover recovery.
Security measures included encrypted inter-service communication, multi-factor validation, and adaptive throttling to prevent brute-force attacks.
Results
- Processed 2.5M+ biometric sessions daily
- Achieved full audit traceability and GDPR compliance
- Reduced system downtime by 60% after containerization
- Integrated easily with third-party identity providers
