Crypto-Biometric: An Overview

With the current advancement in computational technology, the security and privacy of information is under threat. The speed of data processing by modern computers is making traditional cryptographic techniques almost redundant. Cryptographic protocols which hitherto were deemed secure are under threat by bruteforce attack. In lieu of this, more secured cryptographic techniques are being sort to better protect data whether in transit or stationary. The quest for this pursuit has brought to the fore crypto-biometric – the use of biometric features of the user in addition to the traditional cryptographic techniques – techniques for information protection. Systems using biometric features for the protection of information is gaining popularity as there a unique and eternal relationship between a person and his/her biometric characteristics. Hence, harnessing the unique biometric features of an individual and the traditional cryptographic techniques will better protect users’ information. This research paper seeks to highlight the benefits of the incorporation of biometric features and traditional cryptography.
