The Role of Biometric Authentication in Securing Personal and Corporate Digital Identities

Biometric authentication has become a prominent technology in the protection of individual and corporate digital identities, responding to the increasing demand to fight data breaches, identity theft, and fraud. The purpose of this research is to investigate the use of biometric authentication in enhancing digital identity protection, particularly its ability to offer greater security than conventional means, including passwords or PINs. As businesses continue to drive digitalization and cyber attacks become more sophisticated, the requirement for highly secure yet user-friendly authentication methods has become a priority. Although biometric technologies like fingerprint, facial recognition, and iris scanning have gained widespread attention, there are still some research loopholes regarding their real-world usage and limitations in different situations. A critical area that requires more investigation is the performance of biometric authentication across various environments, particularly the uptake of the use of biometric authentication alongside multi-factor authentication (MFA) systems in a bid to enhance security. Also, issues regarding privacy, data management, and the risks that accompany the compromise of biometric data require more investigation.  The research aims to overcome the limitations by providing an analysis of the technical, legal, and ethical aspects of biometric security as well as recommending guidance to organizations seeking to implement these systems for the effective safeguarding of identity. Generally, the research aims to facilitate the ease of implementation of biometric authentication in safeguarding personal and corporate digital identities in the face of evolving security threats.
