Description (English):

ISO/IEC 19794-9:2011 specifies an image interchange format for biometric person identification or verification technologies that utilize human vascular biometric images and can be used for the exchange and comparison of vascular image data. It specifies a data record interchange format for storing, recording, and transmitting vascular biometric information from one or more areas of the human body. It defines the contents, format, and units of measurement for the image exchange. The format consists of mandatory and optional items, including scanning parameters, compressed or uncompressed image specifications and vendor-specific information. Information compiled and formatted in accordance with ISO/IEC 19794-9:2011 can be recorded on machine-readable media or can be transmitted by data communication facilities.

Abstract

Overview

ISO/IEC 19794-9:2011 - Information technology - Biometric data interchange formats - Part 9: Vascular image data defines a standardized image interchange format for vascular biometric systems (vein/back-of-hand/palm/finger). The standard specifies a biometric data record format for storing, recording and transmitting vascular images and associated metadata to enable interoperability among capture devices, comparison algorithms and systems. Records conforming to ISO/IEC 19794-9 can be stored on machine‑readable media or transmitted over networks.

Key technical topics and requirements

Data structure & conformance: Defines mandatory and optional fields, relationships between elements, and the need for an Implementation Conformance Statement (ICS) for producers and users.
Image capture requirements:
- Spatial sampling expressed in pixels per centimetre (no fixed minimum; application dependent).
- Bit-depth: at least 8 bits per pixel (≥128 gray levels; ≥7 bits useful).
- Illumination: near-infrared imaging commonly used (approx. 700–1200 nm); supports reflectance or transmission modes.
- Projection & geometry: images must be orthographic; remove major optical distortions prior to packaging.
- Pixel aspect ratio: default 1:1; non‑square pixels must be documented.
- Standard pose & coordinate system: defines object-to-image mapping and raster scan order to ensure consistent orientation.
Image storage & compression: Supports raw and compressed formats; references established codecs (ISO/IEC 10918-1 JPEG, ISO/IEC 15444-1 JPEG 2000, ISO/IEC 14495-1 lossless) for interchange.
Record components: Biometric Data Record, general header, representation header, extended data, and registered format type identifiers are specified for robust metadata (scanning parameters, vendor-specific info, etc.).
Byte/order conventions: Big‑endian multibyte values; most significant bit/byte transmitted first.

Practical applications and who uses this standard

Use cases: Identity verification, secure access control, forensic and national ID systems, border control, and multi-modal biometric systems where vascular traits (vein patterns) are used.
Stakeholders: Device manufacturers (vein scanners), biometric software developers, system integrators, standards bodies, government agencies, and organizations seeking vendor‑neutral vascular data exchange.
Benefits: Ensures interoperability across vendors, preserves raw/processed image fidelity for algorithm portability, and provides a standardized metadata model for reliable matching and auditability.

Related standards

ISO/IEC 19794 series (Parts 1–14) - framework and other biometric modalities (finger, face, iris, etc.).
Normative references: ISO/IEC 10918-1 (JPEG), ISO/IEC 15444-1 (JPEG 2000), ISO/IEC 14495-1 (lossless compression).

Keywords: ISO/IEC 19794-9:2011, vascular image data, vascular biometric, biometric data interchange, vein recognition, image interchange format, conformance, NIR imaging, interoperability.
