Biometric authentication systems offer improved security based on unique biological characteristics of a user to identify them. This study outlines the design and implementation of an authentication system based on fingerprint recognition—that is also secure—utilizing unique and permanent patterns in fingerprints. The fingerprint recognition system employs a minutiae matching approach, which extracts unique characteristics of fingerprints such as ridge endings and bifurcations, and then compares them with the concept of templates. By employing noise reduction and normalization in the preprocessing stage, the system is designed for successful minutiae vessel extraction from fingerprint images. The system matches tapestry to vestiges based on the Euclidean distance between parse vestiges and the stored templates. An arbitrary/system-fed threshold will decide whether the user is authenticated or not. The proposed system has a robust level of security to reduce unauthorized access to difficulty in broad applications such as mobile devices, secure entry, etc. Evaluation results show high accuracy and performance in real-world experiences and situations that recommend fingerprint biometric authentication systems—like the one proposed in this study—as a standard practice in our security.
