Secure Authentication System Using Biometric Cryptosystem
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 2
Abstract
Online digital information security is gaining drastic significance with the boost and progression of internet communication. With the advent of ecommerce and ebanking and its further evolution, the traditional methods of personal identification like token based methods and knowledge-based methods like PINs, passwords are no longer sufficient for secure transfer of critical data online. Though Biometric Authentication systems are comparatively a better option, they can be vulnerable to several attacks when it comes to Authentication online. Hence, Biometric Cryptosystems are proposed to enhance the security of biometric authentication systems and to create revocable representations of individuals. Alternatively, Steganography techniques play a crucial role in encapsulating encoded biometric data behind an unpredicted carrier. The proposed system employs CASIA-FingerprintV5 database of fifty fingerprint samples and emphasizes on providing improved security to the critical biometric data in two stages (i.e. Biometric Cryptosystem followed by Steganography) before it is transferred online to the Authenticator. At the Authenticator side, the verification and identification process are carried out using Euclidean distance and Hausdorff distance. On analyzing the experimental results, it can be concluded that the proposed system performs better matching when Euclidean distance is used.
