ATM Vault Authentication and Security using Finger Print Biometric with GSM Technology

Security and Authentication of individuals is necessary for our daily lives. Access control systems restrict access to a secured premise or other secured devices (like a safe) only to authorized persons. In this design a biometric (fingerprint based) ATM vault was developed with GSM technology. There are other methods of verifying authentication through password, RFID but this method is most efficient and reliable. To provide perfect security to the bank lockers and to make the work easier, this project is taking help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Unauthorized access is prohibited by designing a system that stores the fingerprints of one or more authorized users. Fingerprint is sensed by sensor and is validated for authentication. If the fingerprint matches, the door will be opened automatically otherwise the buzzer will be activated so that the people near the surroundings will get an alert. A survey showed that there is no proper security in withdrawing cash from ATM’s. There are no proper authentication methods applied for security during ATM transactions. In this paper, security approaches of ATM have been focused on, and have been improved using biometric based authentication technique i.e. Fingerprint recognition. One of the main motive of biometric ATM machine is to prevent unauthorized access means everyone cannot access the ATM means user should present then the access the ATM otherwise not access the Account. The use of biometric in ATM machine for the purpose of security. Biometrics technology is rapidly progressing and offers attractive opportunities. In recent years, biometric authentication has grown in popularity as a means of personal identification in ATM authentication systems. The prominent biometric methods that may be used for authentication include fingerprint, palm print, handprint, face recognition, speech recognition, dental and eye biometrics. In this paper, a microcontroller based prototype of ATM cashbox access system using fingerprint sensor module is implemented. An 8-bit PIC PIC18F4520 microcontroller developed by Microchip Technology is used in the system. The necessary software is written in Embedded C and the system are tested.
