Design of a Fingerprint Biometric Access Control System with GSM Functionality

Abstract

We live in a world with ever-increasing digital technology, hence the need for enhanced security systems is vital. In the past a simple PIN or password would have been sufficient to maintain the integrity of security systems, however with the advancements in technology, these are slowly becoming a secondary method of access control. Biometrics provide an enhanced level of security since they make use of unique characteristics or features of a person making them increasingly popular in security systems. This paper describes a project in which the fingerprint biometrics together with the Arduino Uno are used to provide access to a home security gate. A Global System for Mobile Communications (GSM) module is appended to the system and used to provide an alert when unauthorized access occurs via a cellphone.
