Abstract: Automated Teller Machine (ATM) has been convenient approach than ever before for accessing bank’s account from anywhere anytime. Being an electronic telecommunication device, it helps customer to perform transactions/withdraw cash, make deposits & transfer funds by simply touching few buttons on screen without need for a cashier or bank teller. 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 has been improved using biometric based authentication technique i.e. , face recognition from 3 angles. One of the main motive is to diminish and tranquillize the effects of attacks to ATM by use of biometrics. The end result is strengthened biometric ATM system that will be a defending approach in coming year and will escalate the confidence of customer’s in banking sector.
