The basic structure of a biometric system consists of three main components: the sensor, the feature extraction module, and the matching algorithm. The sensor captures the biometric data, such as fingerprints or facial patterns, which is then processed by the feature extraction module to create a template.
The matching algorithm compares this template with stored templates to verify or identify the individual. Biometric systems are widely used for security purposes and access control in various industries. Biometric systems have gained popularity due to their accuracy and reliability in identifying individuals based on unique physiological or behavioral characteristics.
This has led to their widespread adoption in applications such as border control, mobile devices, and financial transactions. Understanding the basic structure of biometric systems is crucial for realizing their potential in enhancing security and convenience in diverse settings.
