Overview
ISO/IEC TS 22604:2024 - "Information technology - Biometric recognition of subjects in motion in access-related systems" defines requirements and guidance for designing and deploying contactless, in‑motion biometric systems used for secure access. The Technical Specification covers verification and identification processes where biometric characteristics (face, iris, fingerprint, palm and complementary modalities) are captured while subjects are moving, enabling access control without stopping or touching devices.
Key search terms: ISO/IEC TS 22604, in‑motion biometrics, contactless biometrics, access control, biometric recognition.
Key topics and technical requirements
- Scope and definitions - formalizes terms such as in‑motion verification, recognition area, access point, feedback signal and lists normative references (e.g., ISO/IEC 2382‑37, ISO/IEC 19795‑1).
- Biometric modalities - guidance on applicable modalities (face, iris, fingerprint, palm, multimodal/complementary) and their suitability for in‑motion capture.
- Performance and trade-offs - addresses biometric performance, error rates, and the quality vs. speed compromise inherent in in‑motion recognition.
- System flows - describes verification vs identification flows, enrolment practices and management of exceptions (unenrolled users routed to human agents).
- Ergonomics and capture design - requirements for physical placement of capture devices, attraction/attention mechanisms, feedback signals to users, and recognition area design to support reliable capture while subjects move.
- Storage and data handling - considerations for biometric information storage, secure management and authorization lists (authorized, unauthorized, alert lists).
- Accessibility and usability - recommendations on accessibility, acceptable user delay for fluid passage, and user guidance.
- Privacy, consent and security - mandates privacy‑aware design, consent handling, data protection measures and presentation attack detection (reference to ISO/IEC 30107‑3).
- Deployment examples - practical use cases (e.g., fingerprint or multimodal systems) illustrating real-world design choices and constraints.
Practical applications and users
Who benefits:
- Security system architects and integrators designing access control for airports, border control, public transport, workplaces and high‑throughput facilities.
- Biometric product developers and hardware manufacturers (camera, sensor placement, edge processing).
- Privacy officers, compliance teams and procurement specialists evaluating contactless biometric solutions.
- Test labs and system evaluators responsible for performance, accessibility and presentation‑attack assessments.
Common applications:
- Seamless passenger flow at terminals and checkpoints
- Secure, non‑intrusive employee access and time & attendance
- Automated border control and transit gates
- Contactless access in health‑sensitive or high‑throughput environments
