The technology used in biometric authentication includes specialized sensors and software that capture and analyze unique biological traits of an individual, such as fingerprints, facial recognition, or iris scans. These systems utilize algorithms to match scanned biometric data against stored templates, verifying a user’s identity. Biometric authentication offers heightened security compared to traditional methods like passwords, as it relies on unique personal identifiers that are difficult to replicate or forge. Additionally, biometric systems are increasingly implemented in various applications, including smartphones, financial services, and access control systems, enhancing security while improving user convenience.
