The Role of Biometric and Authentication in Security

Biometric authentication is a user identification and authentication method utilizing unique physical or behavioral traits such as fingerprints, facial patterns, iris scans, and voice recognition. This paper explores the advantages of biometric systems over traditional methods like passwords and PINs, highlighting their resilience against replication and theft. We delve into various types of biometric systems, their strengths and weaknesses, and address key research issues that must be resolved for effective deployment in real-world scenarios. We conclude by emphasizing the potential of biometric authentication as a secure and convenient identification solution across various applications.
