Implementation of Enhanced Finger Print based Door Locking System

Security has continuously been a foremost apprehension for industrial applications, various households and across different office environments. The important parameters considered are security and safety. In this paper an enhanced fingerprint biometric system for controlling the door movement in a highly confidential area is presented. At present, the majority of door locking security systems installed across various environments suffers from various lapses. Taking this into consideration, the design and prototype of a biometric fingerprint based door locking system is demonstrated in this paper. The fingerprints of the authorized individual persons are registered separately one by one and licensed to provide access to a facility that is used by multiple users. The program is written such that any number of individual fingerprints can be added or deleted from the database based on the memory incorporated in the system. If the individual’s fingerprint is matched, then the door will be opened, otherwise the GSM module gets activated automatically and a SMS message is sent to the registered user, while simultaneously the alarm also gets activated to alert the people or the security official in the surroundings. The microcontroller used in the present work is Arduino UNO R3 board. The proposed enhanced fingerprint security system is tested in real time and provides a comprehensive security solution and unauthorized individuals are prohibited from entering through the door. In contrast to the other authentication methods such as using RFI and passwords security, the proposed method has proven to be most efficient and reliable.
