A biometric template is a set of stored biometric features. To create a template, we need to get a biometric sample through a capture device, e.g., a camera or fingerprint scanner. The captured biometric sample is further converted into a mathematical file. Thus, the template is a digital representation of biometric samples stored in a biometric database known as ABIS. The process of comparing templates from the database to the obtained samples is called biometric authorization or biometric identification.
