ISO/IEC 19784-4:2011 specifies a biometric sensor interface for a Biometric Service Provider (BSP, see ISO/IEC 19784-1). The interface supports a BSP wishing to provide the BioAPI Service Provider Interface (SPI) functions, whilst removing device handling activity from the BSP. ISO/IEC 19784-4:2011 provides an interface that can be used by all types of biometric sensor, including inter alia image streaming sensors (infrared, face, iris, finger, etc.), voice streaming sensors and digital tablets providing dynamic signature data. It is not in the scope of ISO/IEC 19784-4:2011 to define security and privacy requirements for capturing and transferring of biometric data across the Sensor Function Provider Interface (SFPI).

Abstract

Overview

ISO/IEC 19784-4:2011 - Biometric sensor function provider interface - defines a standardized low-level interface that lets a Biometric Service Provider (BSP) interact with biometric sensors supplied by a separate Biometric Sensor Function Provider (BSFP). The standard is part of the BioAPI family (ISO/IEC 19784) and targets interoperability between BSPs and a wide range of biometric sensors (image cameras, voice sensors, digital signature tablets, etc.). Note: ISO/IEC 19784-4:2011 does not specify security or privacy requirements for capture or transfer across the Sensor Function Provider Interface (SFPI).

Key topics and technical requirements

Scope & purpose: Provides an SFPI to offload device handling from BSPs so BSPs remain independent of vendor-specific sensor details while supporting specific biometric modalities (finger, face, iris, voice, signature).
Conformance: A BSFP shall implement the functions in Clause 8 and the normative annexes; some functions may legitimately return the BioAPIERR_FUNCTION_NOT_SUPPORTED error when optional.
Interface architecture: Defined mechanisms for selecting/loading sensor providers, unit attach/detach, control and status, and event/callback handling.
Core function set (examples from Clause 8):
- BioSFPI_BSFPLoad, BioSFPI_UnitAttach, BioSFPI_UnitDetach
- BioSFPI_QueryUnits, BioSFPI_ControlUnit, BioSFPI_Cancel
- BioSFPI_GetPackets, BioSFPI_DataTransfer (data capture/transfer interfaces)
- Power mode, GUI callbacks, calibration, indicator control
Data transfer modes: Single data transfers, packetized transfers, and streaming (stream interface explained in Annex C). Annexes provide modality-specific data schemas.
Normative annexes:
- Annex A: Imaging biometric sensor units (image parameters, pixel formats, streaming)
- Annex B: Signature sensor units (coordinate systems, sample rates, dynamic signature data)
- Annex C (informative): Strategies for obtaining sensor data across SFPI (memory management, streaming)

Applications and who uses it

BSP developers looking to support multiple sensors without embedding device drivers.
Sensor manufacturers / BSFP implementers building standardized drivers or middleware to enable plug-and-play use of biometric hardware.
System integrators deploying multi-vendor biometric solutions for access control, identity verification, enrollment stations, or forensic capture.
Test labs and compliance teams validating BioAPI-compatible sensor/BSP interoperability.
