Driven by advancements in hardware, software, machine learning, and artificial intelligence, biometric technology is today more accessible than ever, making it easier for any organization to deploy the technology and reap its benefits.

Ray Fernandez, writing for TechRepublic Premium, presents this biometrics glossary to help you understand the tech behind the sector and the core fundamentals of the industry.

Featured definition from the glossary:

Degrees of freedom

The number of independent measurements or variables used to characterize a biometric trait. DOF impact how accurate a biometric authentication system is. The higher the DOF of a biometric trait, the more accurate the matching process will be. DOF of a biometric trait depends on several factors, such as the quality of the sensor used to capture the biometric data and the quality of the biometric template. For example, the DOF of a fingerprint will be impacted by the resolution of the fingerprint scanner or the environment in which it was scanned.
