Abstract

The rapid digitization of financial services has fundamentally transformed banking operations, with mobile and online platforms becoming the primary channels for customer interactions. This digital transformation, while offering unprecedented convenience, has simultaneously created significant security challenges, particularly in the realm of user authentication. Traditional authentication methods, including passwords, PINs, and security questions, have demonstrated increasing vulnerabilities to sophisticated cyber attacks, social engineering, and credential theft. The financial industry's response to these challenges has increasingly turned toward biometric authentication as a potential solution, leveraging unique physiological and behavioral characteristics to verify user identity. Biometric authentication represents a paradigm shift from knowledge-based and possession-based authentication factors to inherent human characteristics. The theoretical foundation of biometric systems rests on the premise that biological and behavioral traits are inherently unique, difficult to replicate, and permanently associated with individuals. However, the transition from theoretical promise to practical implementation has proven remarkably challenging for financial institutions. Current biometric implementations in banking often suffer from fragmented approaches, inadequate consideration of user experience, and insufficient attention to the complex regulatory landscape governing financial data protection. This research addresses the critical gap between biometric technological capability and effective implementation strategy in banking contexts. While numerous studies have focused on improving the technical accuracy of individual biometric modalities, few have comprehensively examined the strategic considerations necessary for successful deployment in the highly regulated, security-sensitive environment of financial services. Our work introduces a novel implementation framework that transcends conventional technical optimization to encompass organizational, user-centric, and regulatory dimensions of biometric deployment.
