Development of Biometric based Intelligent Authentication System for Bank Lockers

Abstract

This paper explores various biometric techniques applied to locker security systems, focusing on the design of a fingerprint-based biometric locker. With the increasing need for security in safeguarding valuable items such as gold, documents, and currency, the proposed system offers a robust solution by integrating two microcontrollers—ATmega16 and PIC16F877A—with peripheral devices. The system is further enhanced with a cloud-based Adhaar card database, mobile app, and webpage, ensuring that sensitive information can be accessed securely from anywhere. Leveraging an R305 fingerprint module, the system provides biometric security and incorporates IoT capabilities via the HC05 Bluetooth module. A servomotor unlocks the locker when a valid fingerprint or PIN is entered, adding a layer of convenience through an android app, which features QR code scanning for Adhaar information management. The accompanying webpage offers detailed insights, including a video demonstration of the system’s operation.This biometric locker system is both user-friendly and highly secure, leveraging fingerprint recognition as the primary authentication method. Fingerprint data is unique to each individual, making it a reliable choice for securing lockers. The system allows for easy user management, enabling the addition and deletion of users through the fingerprint sensor, which interfaces with the microcontroller to operate the door based on the accuracy of scanned data. The result of the authentication process is displayed on an LCD screen, indicating whether the user is authorized. By combining biometric security with the convenience of mobile and web-based management tools, the proposed model offers an innovative and efficient solution for enhancing bank locker security.
