Background

To be interoperable, components within a system mustadhere to common specifications or standards:

Interface standards: define how the components interact

Data interchange format standards: define what data records are

exchanged

How can developers and consumers of information systemsensure conformance to standards?

Development of base standards and detailed definitions of

conformance clausesDevelopment of standardized conformance testing methodologies

and tools

Perform conformance testing of system components using thesemethodologies and tools

Application ProgrammingInterface(API)

API

Defined way for a software application to communicate (requestservices and receive responses) with a technology/service module

An API standard defines a common method of interfacing to a

particular technology Usually composed of a set of function calls with data/control

parameters and defined data structures

BioAPI

Ensure interchangeability of biometric system components

Ensure biometric system tiers use common language

Ensure independence from vendor implementations

Advantages of BioAPI

Simple application interfaces and standard modular accessto biometric functions, algorithms, and devices allow:

Rapid development of applications employing biometrics

Flexible deployment of biometrics across platforms andoperating systems

Improved ability to exploit price performance advancesin biometrics

Enhanced implementation of multiple biometric

modalities (e.g., fingerprint, voice, face, iris)

Conformance to BioAPI

BioAPI the cornerstone standard for multi-componentbiometric system architectures

Interchangeability of biometric system components

Independence from vendors implementations

Simplified implementation of multiple biometric modalities (e.g.fingerprint, voice, face, iris)

Conformance of BioAPI components

Do vendor products conform to BioAPI Standards?Is it possible to validate claims of conformance?

How do we validate for conformance?

BioAPI Conformance Test Suite (CTS)

BioAPI CTS is an implementation of a standardizedconformance testing methodology

BioAPI CTS assesses the conformance of an

Implementation Under Test (IUT) to the BioAPIspecification

IUT can be composed of the following BioAPI softwareimplementations
