Biometric Authentication is a security process that relies on the unique biological characteristics of an individual to verify that they are who they say they are. This method uses physical traits such as fingerprints, facial recognition, iris scans, and voice patterns to provide secure, user-friendly access to systems and data.
Biometric authentication systems capture and store an individual’s unique biological data. When access is attempted, the system scans the individual's biometric data and compares it to the stored information. If there is a match, access is granted. Here’s a breakdown of the process:
1. Capture: The system captures a biometric sample of a trait, such as a fingerprint or a facial structure.
2. Extraction: Unique data from the sample is extracted and converted into a digital format.
3. Comparison: The new biometric data is compared to existing data on file. If the data matches, authentication is successful.
