Cloud Security Solution: Fragmentation and Replication

Computer Engineering

Nowadays the world is known as digital world. As the use of the internet increases day by day, Cloud Computing becomes popular technology among users, customers. The customers are attracted towards the Cloud due to its offers like on-demand network access, reduced space, pay-per-use service, flexibility, scalability etc. Though the remarkable use of cloud computing, there are some hurdles to acceptance. Performance, security, availability, quality of service are the main challenges and issues cloud computing has to face. One of the most barriers is the security because users have to share their information among the cloud nodes. The location of information storage is not known to the user. In this paper, we proposed a new solution which presents the Graphical Authentication System with fragmentation and replication technique. The graphical password authentication provides a security and usability of the proposed system. Here in this system, when user upload any file that the file is fragmented and replicated to provide a better security and performance in terms of access time. When any network is not available to access then, the data will be accessed by using replicas in very short time. T-coloring method is used to assign the fragments and their replicas to improve the security. This system mainly focuses on the data and authentication system with good performance.
