This research project explores the security and privacy implications of using biometrics for authentication. It examines the increasing use of biometrics in various sectors, including government and private organizations, and analyzes the potential risks associated with this technology. The study delves into the vulnerabilities of biometric systems, including data breaches and spoofing attacks, and discusses the importance of implementing robust security measures to protect sensitive personal information. The research also explores the ethical considerations surrounding the use of biometrics, particularly in relation to privacy and data protection. The paper concludes by proposing a model for integrating biometrics into ATM systems, highlighting the potential benefits and challenges of this approach.
