Using biometric data for identification has significant implications for privacy and security. On one hand, it enhances security measures by utilizing unique physical or behavioral traits, making unauthorized access more difficult. Examples include fingerprints, facial recognition, and iris scans. However, the collection and storage of such sensitive data raise concerns regarding data breaches and personal privacy. Misuse of biometric data or inadequate protection can lead to identity theft or unauthorized surveillance. Thus, implementing strong security protocols and regulatory measures is essential to mitigate risks related to biometric identification systems.
