IMPROVING SECURITY LEVEL OF ATM BANKING SYSTEMS USING BIOMETRIC KEY BINDING CRYPTOGRAPHIC TECHNIQUE
Publication Date : 31/01/2017
With rapid growth in the use of automated teller machines (ATMs), there is need to develop secure, robust and reliable schemes to securely/correctly authenticate users. The conventional ATM authentication schemes available are mostly cryptographic based and this gives room to lots of vulnerabilities. This paper presents an improvement on the conventional cryptographic security scheme currently used in ATMs by proposing the application of Biometric Key Binding (BKB) technique which fuses biometric security with cryptographic protocols on biometric template generated from input test images. The application of BKB not only protects the information of the user’s biometric features, but also securely releases cryptographic key that is bound with biometric trait in a monolithic framework. The ease and protection provided by the proposed technique promotes improved security for widespread use of cryptographic systems. This technique provides high output entropy keys and also conceals original biometric data such that it is impossible to recover the biometric data even when the stored information in the system is open to an attacker.
