Abstract

Security has always been a key concern in both the home and the workplace, and numerous measures have been implemented to solve the issue. Most main door lock security systems have many gaps that can be exploited to get access to desired locations, posing a threat to a secure lifestyle and a healthy working environment. Terrorism and unwanted access to places have also become serious issues in recent years, necessitating the implementation of a security system to prevent unauthorized access, particularly in shared access environments. This study presents a design and prototype of a biometric fingerprint-based door lock system that takes this into the report. Biometric technologies, such as fingerprints, give instruments for enforcing trustworthy system logs and safeguarding an individual's right to privacy. When RFID cards or passwords are shared or stolen, door lock mechanisms based on RFID or passwords can be readily infiltrated, necessitating the use of a biometric-based security system for facilities with shared access. Fingerprints of authorized users are enrolled and confirmed in the proposed system to grant access to a facility that is used by various users. User can also be deleted from the system, and a new user can be added. This project put in place a centralized control system that allows us to manage who has access to particular rooms and who doesn't.
