GAO’s Cloud-based Electronic passport (ePassport) Authentication System
GAO’s cloud-based Electronic passport (ePassport) Authentication System modernizes border control, identity validation, and travel document security by integrating advanced IoT wireless technologies such as BLE, RFID, UWB, Wi-Fi HaLow, NB-IoT, and Cellular IoT. This cloud-driven identity verification ecosystem uses secure cloud infrastructure for high-speed authentication, remote management, real-time analytics, and multi-agency connectivity. Through the cloud, passport data can be verified against national and international identity databases with unmatched efficiency, supporting airports, seaports, land border checkpoints, consulates, and secure facilities. Our cloud platform processes digital signatures, biometric templates, chip-based credentials, and session logs using highly redundant compute clusters and encrypted storage. GAO’s decades of R&D investment and stringent QA practices ensure that immigration authorities, government agencies, and critical infrastructure operators receive a resilient, scalable, and globally accessible authentication environment. With offices in New York City and Toronto, we support mission-critical identity workflows across the U.S., Canada, and beyond.
Cloud Architecture of GAO’s Cloud-based ePassport Authentication System
GAO’s cloud architecture is engineered for national-level identity authentication workloads requiring real-time access, strong cryptographic assurance, and seamless multi-agency integration. Field devices—using RFID readers, BLE beacons, UWB sensors, Wi-Fi HaLow terminals, NB-IoT modules, or Cellular IoT connections—interface with inspection kiosks, border control booths, traveler gates, and handheld verification units.
Key cloud architectural elements include
- Passport Data Capture Layer: RFID-enabled ePassport readers extract chip data, biometric templates, security object documents (SOD), and digital signatures. BLE- or UWB-assisted positioning provides booth-to-gate guidance and proximity validation.
- Edge Inspection Layer: Border control workstations and automated gates execute initial checks such as Basic Access Control (BAC), Password Authenticated Connection Establishment (PACE), and chip integrity validation. Secure buffers store temporary session data.
- Cloud Transport Layer: Encrypted MQTT/HTTPS tunnels manage passport data transmission with message integrity checks, latency correction, and automated retry logic for high-volume border environments.
- Cloud Verification Layer: Kubernetes-orchestrated microservices authenticate signatures, cross-check biometric hashes, validate issuing-country certificates, and correlate traveler data with watchlists or visa registries.
- Interagency Identity Integration Layer: Secure connectors synchronize identity records with national databases, INTERPOL feeds, and visa management systems.
- Audit & Oversight Layer: Immutable logs document every verification cycle for compliance, investigations, and operational reporting.
- Operations Console: A role-based dashboard used by immigration officers, supervisors, and government analysts for monitoring, alerts, statistics, and policy-based access settings.
