Cloud based secure banking application

Abstract

Individual Banks store vast amounts of user sensitive data on their private server. Sharing this data with other banks will provide an efficient way of offering their customers with personalized services and will deliver value-added data services to the entire banking sector. This data is highly sensitive and requires a secure sharing medium. However, secure data sharing is a taxing and troublesome job. This paper proposes a framework for sharing Secure Sensitive Data between banks which includes Secure Data Transfer, Secure Data Storage, Secure Data Delivery and Usage & Destruction of Data which uses Variable AES in place of Normal AES for securely storing the data as Variable AES is an enhancement to Normal AES since it uses new sub key for each block of data. This framework provides security of the user's sensitive data and shares this data safely. To allow banks to share their data we have implemented this framework using the cloud application where we provide user authentication, data integrity and access control using the Proxy Re-Encryption mechanism. At the same time, data owners (Bank) retain complete control of their own data in a safe and sound environment.
