Multilevel Authentication sing OTP, QR-Code and Hadamard Transformation

Abstract

In this technical world everything becoming online because new technologies emerging day to day in the world. Banking is one of the important sector which have to provide more secure transactions. Everyday people converting to online due to less spending time and processes becoming fast. Providing the security is biggest challenge in the technical world. There are more number of malicious links which diverts the user and access the user sensitive information of users which is illegal. The main issue of the online banking is to verifying the authenticity of the user. Here we proposed a mechanism with the use of One Time Password (OTP), QR Code i.e., Quick Response Code using Hadamard Transformation. OTP is used for first level of authentication. Hadamard Transformation and digital watermarking is used to hide the sequence which is secret key for second level of authentication. This mechanism will provide a high level security for authentication. Hence we used android application for performance evaluation.
