ABSTRACT

One of the most commonly occurringproblems in the recent years are the ATM (Automatic teller machine) frauds. People lose their money due to lack of awareness. The major reason for such kind of actions is the attacks made on the 4-digit pin (Personal Identification Number)which is being used as a password for authentication in ATM.The attacks such as shoulder surfing and recording attacksare becoming more common in ATM. The PIN number is not given proper security to overcome such attacks.The proposed method uses the pin entry methods which are resistant to such attacks.The pin entry methods that used in the proposed system are black white method, improved black white method and session key method. The main aim of the proposed system is to create an android application which performs the ATM transactions that can be installed in a smart phone. The concept of virtual money is also used. The hash function is used to send the PIN securely through the public channels.
