An Improved Encryption Scheme with Fingerprint Image using Hashing Technique and Linear Congruential Method (original) (raw)

2011

Abstract

Abstract — This paper proposes an encryption method which can be used for multipurpose applications such as ATM, online transactions and other security measures. The method consists of four phases. The first phase consists of obtaining the fingerprint image and constructing an initial code block for that. The second phase is hashing the initial code block and generating a secure code block. Linear congruential method is applied to this code to generate a substitution array in the third phase. The encryption is done in the last phase where cipher text is obtained based on the substitution array and plain text.
