Implementation Biometric Data Security in Remote Authentication Systems via Network Steganography

Abstract

The need of protection user biometric information increases in consequence of the development of biometric authentication systems. This is due to the fact that fingerprints, iris patterns, face geometry and other biometric data are unique and cannot be replaced. There are various methods for protecting biometric data, but the probability of compromise remains when this data is transmitted over the network. The article presents a method of remote biometric authentication using network steganography for different systems. This improves the reliability of the protection of user biometric data. Analysis of existing methods of network steganography, methods of biometric authentication. Synthesis of new method of remote authentication, that will increase the security of user biometric data from unauthorized access. Modeling a remote authentication system using network steganography methods and user biometric data is the method of this work. The common methods of biometric authentication, existing methods for their protection and existing network steganography methods were analyzed. The method of remote biometric authentication using network steganography for various systems is presented. The remote authentication system using network steganography was simulated. The resistance of the investigated methods to detection was evaluated. The effectiveness of the proposed method for protecting biometric data was investigated.
