What Does Biometric Engine Mean?
A biometric engine is the core program that controlls the different hardware and components of a biometric system. The biometric engine controls the enrollment, capture, extraction, comparison and matching of biometric data from a user.
It is based on a set of algorithms that facilitate the steps in the recognition process, as well as the intermediary processes like image enhancement, determining quality and the extraction of distinguishing features.
Techopedia Explains Biometric Engine
Different software or firmware might run the different hardware of the biometric system, but there is a core system connecting them all. When connected together, they form the biometric engine. It is the efficiency of this engine that dictates the quality of the system. Even with state of the art hardware, if the biometric engine is not functioning correctly, then the system will get many errors and false readings or identifications.
Off-the-shelf biometric systems have biometric engines of their own, but more powerful and proprietary biometric engines are required for higher security and accuracy. These engines must be developed specifically for the organization that needs them. In addition, they should have a special way of handling scans to reduce false positives and impersonator access.
