T5-OmniMatch ABIS by TECH5 is a multi-modal biometric matching platform that performs identity matching across face, fingerprints, and iris. The system operates in both 1:1 (verification) and 1:N (identification) matching modes through REST APIs using HTTPS protocols. It incorporates biometric template protection technology compliant with ISO 30136 standards and combines artificial intelligence and machine learning techniques with traditional methods. The platform is multi-process and multi-threaded, designed for large-scale authentication systems where response time is critical for Quality of Service (QoS). Operating on both Windows and Linux platforms, it enables secure, flexible, and privacy-preserving large-scale biometric systems with minimal hardware requirements.
