Learn moreEnterprise Platform for Internal Biometric Identity Verification

For Sber, we developed a project-specific internal platform for biometric identity verification, designed to support high request volumes, controlled availability, and auditable security processes within a regulated enterprise environment. The platform combines modern microservices, encrypted communication, and intelligent load balancing to enable near-real-time biometric authentication workflows for internal web and mobile applications.
This case study describes a project-specific internal system implemented under strict contractual and regulatory conditions. The architecture and descriptions are presented in an abstracted form and do not disclose biometric data, security mechanisms, or confidential internal processes.
Sber needed a new authentication layer that: • Reliably processes high volumes of biometric requests • Is secure, scalable, and fault-tolerant • Supports comprehensive logging & compliance • Can be integrated into a containerized infrastructure • Seamlessly integrates with existing identity providers In short: a modern, modular platform for critical security processes.
1 — Microservice-Based Architecture We developed independent services for: • biometric validation • session and token management • document and ID verification • event and audit logging Communication between services occurs asynchronously via message queues. 2 — Containerization & Orchestration All services were implemented using Docker and operated in Kubernetes: • automatic horizontal scaling • high fault tolerance (self-healing) • deployments designed to minimize downtime and release-related interruptions 3 — Security & Compliance The system was developed in alignment with security practices commonly required in regulated financial environments: • encrypted service-to-service communication • multi-factor validation • adaptive throttling mechanisms • comprehensive audit traceability 4 — Integration & Extensibility The platform was designed to flexibly integrate into: • existing identity providers • internal banking systems • mobile and web apps

The architecture developed in this project demonstrates architectural principles commonly applied in modern security-critical systems. The same principles — modularity, security, scalability, and clear responsibilities — now flow into our startup and enterprise projects, where reliability and data protection are crucial from the start.
