Conformance Test Suite Implementations for Common Biometric Exchange Format Framework (CBEFF) Data Structures | NIST

Biometric technologies are able to establish or verify personal identity against previously enrolled individuals. Used alone, or together with other authentication technologies such as tokens and passwords, they can provide higher degrees of security than other technologies employed alone, and can also be used to overcome their weaknesses. Existing biometric interface standards define data structures called Biometric Information Records (BIRs) that contain biometric data and associated metadata that describes the biometric data. BIRs often are used for the protection, interchange, transmission and storage of biometric data. This paper describes a conformance testing methodology for BIRs that conform to instantiations of Common Biometric Exchange Formats Framework (CBEFF) and discusses the characteristics and functionality of Conformance Test Suite (CTS) implementations developed at NIST to support conformance testing of these data structures. Ongoing research and development work on testing architectures to support these CTS implementations is discussed.
