A survey of biometric approaches of authentication

The increasing need for better authentication methods against hackers has called for the use of the biometric authentication method to guard against unauthorized access into the systems. The used of human characteristics for biometrics provides authentication for different kind of systems. However, poor quality of authentication still allows hackers gaining access to these systems. Many biometrics authentication approaches have been proposed to improve the authentication accuracy and other related quality measures. This survey aims to provide a state-of-the-art fingerprint and password biometric authentication approaches. Their challenges have been presented and discussed in terms of biometric authentication. Furthermore, the strengths and weaknesses of each of the fingerprint and password biometric authentication are discussed and compared. The findings show that fingerprint image quality and password authentication is still an active research area where performance requires improvement. Also, the graphical password indicates a promising future direction for enhancing password methods.
