A novel method to enhance the security of ATM using biometrics

Nowadays we are using the pin number for security in ATMs, which replaced signature based system. The pin based security is the simplest level of security. The pin number is a unique number which is encrypted and decrypted during transaction. Nowadays the pin number can be extracted through many ways, for fraudulent activity. So, as a solution the pin number can be replaced with biometric security. The biometric security may be fingerprint, retina and so on. Nowadays, the system is used to compare the input image with the image in the database and if they are verified, the bank staff would disperse the cash. But the proposal model would completely replace the pin number with biometric system and the machine would disperse the cash when the comparison gets satisfied. Thus the security of the transaction is improved to a greater extent.
