Iris + Face Dual-Modal Access Control for Shunde Rural Commercial Bank
Shunde Rural Commercial Bank partnered with HOMSH Technologies to deploy an enterprise-grade iris + face dual-modal access control system, maximizing vault security and streamlining identity verification across all bank premises.
Challenge
As a major rural commercial bank serving the Shunde district, the institution faced multiple security challenges:
- Vault Security: The vault's AB interlock doors required the highest level of biometric authentication to prevent unauthorized access, with bidirectional verification for both entry and exit
- Multi-Zone Access Control: Different security levels were needed across cash handling areas, non-cash zones, VIP rooms, server rooms, and general office areas
- Identity Fraud Prevention: Traditional access methods (cards, PINs) were vulnerable to sharing, theft, and cloning
- Regulatory Compliance: Banking regulators increasingly require biometric authentication for high-security zones and transaction authorization
- Integration Requirements: The new system needed to integrate seamlessly with the bank's existing security management platform
Solution
HOMSH deployed a complete banking iris recognition system consisting of:
#### Vault AB Door — Triple Authentication (N+1 Mode)
The vault's interlock AB doors feature bidirectional iris + face dual-modal recognition terminals. Personnel must complete three-factor authentication — password verification + face recognition + iris recognition — before the door opens. The N+1 mode adds remote confirmation from the security control room for an additional layer of authorization.
#### Multi-Zone Access Deployment
- Cash Replenishment Door: N+1 mode iris + remote confirmation
- VIP Room: Staff iris access with attendance tracking
- Office Areas: Iris-based access control and time attendance
- Interlocking Passage Doors: AB door system with anti-passback and anti-tailgating
#### Cloud-Based Comparison Platform
An iris + face dual-modal comparison cloud service platform provides backend matching support for all front-end access devices. The platform integrates with the bank's existing security management system, completing the pre-door-opening identity verification workflow.
System Architecture
The banking iris recognition system follows a three-tier architecture:
- Front-End Devices: Iris capture terminals (desktop, self-service kiosk, and handheld), iris access control terminals, and iris passage gates deployed at all entry points
- Management Platform: Centralized iris identity authentication platform handling personnel registration, device management, permission assignment, attendance reporting, and anomaly alerts
- Backend Databases: Iris identity database, device registry, and historical access records with full audit trail
Key Technical Features
- Iris + Face Dual-Modal Recognition: Combines iris (FAR 10^-7) and face recognition for maximum accuracy
- Bidirectional Verification: Both entry and exit require biometric authentication at vault doors
- PhaseIris Algorithm: HOMSH's proprietary 3rd-generation iris algorithm with hardware-level liveness detection
- Platform Integration: Open interfaces for seamless integration with existing bank security and alarm systems
- Cross-Platform Management: Software supports Windows 7+, Linux, and iOS for flexible administration
- Personnel Database Management: Supports employee database, whitelist, blacklist (linked to public security), frequent visitor database, and temporary access database
