Biometrically Secured ATM Vigilance System

The increase in electronic transactions has contributed to a higher demand for fast and precise identification and authentication of users. In ATM's, biometric-based authentication offers different benefits. Fingerprints and facial identification are used in biometrical authentication. The drawback of the current ATM authentication method is the use of password-PINs. Since PINs can be tracked and misused quickly. Our planned system is intended to provide greater protection for ATMs to achieve security and to resolve these criminal activities. Here, the PINs are replaced by randomly created OTP that are sent through the IoT. The goal of the work is to fully eradicate the use of ATM cards. The customer will be allowed to continue with the transaction after biometric and OTP pin authentication. The account will be blocked in the event of three consecutive incorrect attempts. This initiative also deals with ATM fraud prevention. In case of any suspicious activity is detected through the vibration sensor results in the closing of ATM doors followed by releasing of the fainting gas and alerting the surroundings. This will catch the perpetrator engaged in the crime and prevent the fraud from taking place.
