EVALUATING THE SECURITY AND PRIVACY IMPLICATIONS OF USING BIOMETRIC DATA FOR AUTHENTICATION.

Abstract

The increasing adoption of biometric data for authentication in various domains has revolutionized identity verification systems by offering enhanced security, efficiency, and user convenience. Biometric authentication, leveraging unique physical and behavioral traits such as fingerprints, facial recognition, and iris patterns, has become a preferred alternative to traditional password-based systems. However, its implementation raises critical concerns regarding the security and privacy of sensitive biometric information. Unlike passwords, compromised biometric data cannot be reset, posing significant challenges in protecting individuals' identities.

This study evaluates the security vulnerabilities inherent in biometric systems, including spoofing attacks, database breaches, and template aging. It also examines the privacy implications of biometric data collection, storage, and potential misuse, emphasizing the importance of transparent data management practices. Furthermore, the research assesses existing regulatory frameworks such as the GDPR and Biometric Information Privacy Act (BIPA), highlighting gaps in global standards for biometric data protection.

Through a comprehensive analysis of biometric modalities and their implications, this study identifies key challenges and proposes technological advancements and policy recommendations to enhance the security and privacy of biometric systems. By addressing these concerns, the research aims to support the development of more secure and privacy-conscious biometric technologies, balancing innovation with ethical and legal considerations.
