**Biometric data** is a significant component of identity verification, utilizing unique physical characteristics such as fingerprints, facial recognition, or iris scans. This type of data enhances security by providing a reliable method to authenticate users, reducing the likelihood of unauthorized access compared to traditional password systems. Biometrics offer a combination of convenience and accuracy, as they are difficult to replicate or steal. Moreover, as technology advances, biometric solutions are becoming increasingly accessible, prompting wider adoption across various sectors, including banking, healthcare, and mobile devices.
