Overview
ISO/IEC TS 22604:2023 - "Information technology - Biometric recognition of subjects in motion in access-related systems" is a Technical Specification that defines requirements and guidance for developing contactless, in‑motion biometric solutions for secure access. The standard covers systems that capture biometric characteristics (e.g., face, iris, fingerprint, palm) while people are moving, enabling verification or identification without stopping or touching any device.
Key topics and technical requirements
The document addresses practical and technical considerations for reliable in‑motion biometric recognition:
- Scope and purpose - Requirements for verification and identification in access-related environments using contactless biometrics.
- Performance and error rates - Guidance on biometric performance, trade‑offs between quality and speed, and how to balance user flow with accuracy.
- Verification vs identification - Design differences and implementation considerations for in‑motion verification (credential-presented) and identification (prior enrolment).
- Process flow and recognition area - Definitions and recommended process flows for recognition, enrolment, and exception handling at an access point.
- Applicable modalities - Supported biometric modalities and special considerations for face, iris, fingerprint, palm and complementary modalities.
- Enrolment quality and ergonomics - Requirements for enrolment, device placement, attraction points, feedback signals and capture ergonomics to ensure good data while preserving user experience.
- Data storage and security - Guidance on biometric information storage, data protection, consent, and secure system design.
- Presentation attack detection (PAD) - Importance of PAD per related standards to detect spoofing and attacks.
- Accessibility, usability and guidance - Requirements for accessible, non‑intrusive systems and acceptable user delay for fluid passage.
- Deployment examples and use cases - Practical illustrations including single‑modality and multimodal systems.
Applications and typical users
ISO/IEC TS 22604:2023 is intended for organizations designing, deploying or regulating biometric access systems:
- System architects, security engineers and integrators building access control, border control, airport passenger flows, workplace time & attendance, and transit systems.
- Biometric technology vendors developing contactless in‑motion capture devices and algorithms.
- Facility managers, integrators and public authorities seeking interoperable, privacy‑conscious biometric solutions.
- Privacy, compliance and procurement teams assessing biometric security, consent mechanisms and usability.
