What is a biometric template?

A biometric template is a digital representation of an individual’s biological traits for identification. It serves as the core of biometric systems, where unique characteristics such as fingerprints, facial features, or iris patterns are analyzed and converted into a format that can be stored and compared against during authentication processes.

When an individual seeks access to a secure area, their biometric data is captured and compared to the biometric templates previously stored in the system database. If there is a match, access is granted. This method enhances security by relying on something intrinsic to the individual, making it much harder for unauthorized users to gain access.

In contrast, other options do not accurately describe what a biometric template is. Visitor access management relates more to overseeing and controlling the entry of guests into a facility, access cards represent tangible items for entry that can be lost or stolen, and records of denied access attempts pertain specifically to monitoring security breaches without any direct relation to the biometric templates used for identification.
