Manjula 3 1 Student, Computer Science & Engineering, VIT University, Tamil Nadu, India 2 Student, Computer Science & Engineering, VIT University, Tamil Nadu, Indi 3 Professor, Computer Science & Engineering, VIT University, Tamil Nadu, India Abstract This work will demonstrate a case study of a secure multiple bank transaction log. In particular we have implemented and evaluate a multiple bank transaction maintenance log. In this application we have implemented a transaction catalog which will maintain the transaction log from various bank in which the user has accounts. In this application we have identified a set of security issues and have applied the appropriate approach to minimize these security issues.

INTRODUCTION The use of mobile devices is increasing day by day. Every day there is an increase in the processing and computation power of the mobile devices and new technologies are being implemented to support the growing need of the mobile technology. Now database management is not only limited to the field of web technology but has expanded itself to cover mobile technologies as well. We have developed an application that comprises of a central database connected through a server to consortium of different banks and a number of autonomous mobile users with a mobile application. One of the most important issue of concern in this application is providing sufficient security and privacy of the user data. Security issues of data flow through mobile devices are of prime importance as this involves the consortiums of different banks which will be carrying the important private data. We have come up with a solution that will ensure the security of the user data through an additional layer of security that we will discuss in the later part. 2. SECURE TRANSACTION LOG We have considered the following system to maintain a secure transaction of multiple banks; our application is basically divided into three parts:  A mobile device running on the Android Platform.  A mobile database maintaining the transaction log.  A third party Auditor for additional layer of security  A PHP based web server.  Assumed bank consortium. Fig-1: Secure transaction log of different bank 2.1. Mobile Device The application running on the mobile device comprises of an interactive user interface. This user interface is compatible to all the android versions in the market. Through this user interface, user can interactively maintain their transaction log both in offline and online modes [2]. When the client is operating in offline mode then the client has a privilege to maintain the transaction log manually without
