ISO/IEC 19795-4:2008 prescribes methods for technology and scenario evaluations of multi-supplier biometric systems that use biometric data conforming to biometric data interchange format standards.

It specifies requirements needed to assess

• performance available from samples formatted according to a standard interchange format (SIF),
• performance available when samples formatted according to a SIF are exchanged,
• performance available from samples formatted according to a SIF, relative to proprietary data formats,
• SIF interoperability by quantifying cross-product performance relative to single-product performance,
• performance available from multi-sample and multimodal data formatted according to one or more SIFs, and
• performance interoperability of biometric capture devices.

In addition, ISO/IEC 19795-4:2008

• includes procedures for establishing an interoperable set of implementations,
• defines procedures for testing interoperability with previously established sets of implementations, and
• gives testing procedures for the measurement of interoperable performance.

It does not

• establish a conformance test for biometric data interchange formats, or
• provide test procedures for online data collection.
