Iris Recognition Criminal Investigation System
A municipal public security bureau in Guangdong Province partnered with Homsh Technology to deploy an iris recognition system for criminal investigation and identity verification, enhancing the bureau's forensic capabilities.
Challenge
The public security bureau required a reliable biometric identification system that could rapidly match suspects against a large-scale database. Existing fingerprint-based systems faced challenges with worn or damaged prints, and face recognition was susceptible to disguise. The bureau needed a modality that was both highly accurate and resistant to tampering.
Solution
Homsh deployed a comprehensive iris identity verification system comprising server-side infrastructure and front-end collection devices. The system was built on the PhaseIris recognition algorithm running on Homsh's proprietary iris recognition chips.
System Architecture
- Server Platform: Centralized iris identity database with capacity for over 1 million records, featuring 1:N identity search, 1:1 verification, and blacklist monitoring
- Front-End Devices: Desktop iris collection terminals deployed at booking stations, detention facilities, and mobile checkpoints
- Integration Layer: Connections to existing police information systems for comprehensive cross-referencing
Key Capabilities
- 1:N Identity Search: Rapid matching of captured iris patterns against the entire database
- 1:1 Verification: Instant identity confirmation for known subjects
- Blacklist Alerts: Real-time alerts when flagged individuals are detected
- Audit Trail: Complete chain-of-custody documentation for forensic use
Results
The iris recognition system has significantly enhanced the bureau's criminal investigation capabilities. Iris biometrics provide a reliable identification method that cannot be altered or disguised, proving particularly valuable for cases where traditional biometrics are unavailable or unreliable.
