A biometric is defined as a measurable biological or behavioural characteristic of people that can be used to automatically determine or verify their identities. Biological characteristics include fingerprints, the iris and the face, while behavioural characteristics include the voice and gait (manner of walking).
Biometric technology is used in computer-based systems to verify or to determine identities of people, often in access control systems and in large-scale identity management systems such as those used by governments.
The CSIR’s experts in this field focus on the development of computer algorithms to implement the functionality required to verify or determine identities of people using biometrics; such as algorithms to compare fingerprints, and algorithms to enhance fingerprints. These algorithms are packaged into software development kits which can be used by clients who develop biometrics recognition systems.
The CSIR’s work has thus far focused mainly on the development of algorithms for processing fingerprints and includes the development of algorithms for extracting minutiae points and for matching minutiae points; as well as the development of algorithms for the processing of 3D fingerprints that are captured using an OCT (Optical Coherence Tomography)-based fingerprint scanner. The scope of the work has been extended to include other biometrics, such as the iris and the outer ear structure.
