Abstract
Identification and verification of a person today is a common thing; which may include door-lock system, safe box and vehicle control or even at accessing bank accounts via ATM, etc which is necessary for securing personal information. There is need for improve security in ATM transactions. Due to tremendous increase in the number of criminals and their activities, the ATM has become insecure. ATM systems today use an access card and PIN for identity verification. The Personal Verification Number (PIN) does not give good security.
The fingerprint is unique and cannot duplicate by others. This system combines the pin verification and fingerprint recognition technology for identification. With fingerprint recognition technology we embedded the GSM modem connected to the microcontroller. The GSM module is used to generate the 4 digit one time password (OTP) and it send to the main user mobile number when the user enrol the fingerprint to gain access the ATM. The fingerprint of the card holder is collected and stored in the database corresponding to the Bank account details. Every fingerprint which is placed at ATM is checked across the database. The 4 digit one time password should be entered using the Keypad. After enter all the correct information customer can begin the further transactions.
The biometric features cannot be replicated; this proposal will go a long way to solve the problem of account safety. We have used the Arduino Mega 2560 as a core controller. The system uses R305 fingerprint scanner to capture fingerprints with its DSP processor and optical sensor and SIM900 GSM module for generation and transmission of 4 digit OTP. This system can be employed at any application with enhanced security because of the uniqueness of fingerprints. It is convenient due to its low power requirement and portability.
