As the use of the internet increases day by day, Cloud Computing becomes popular technology among users, customers, in scientific field and industries. 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 tremendous use of cloud computing, there are some barriers to adoption. 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. User only uses the services provided by the cloud. 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. Fragmentation avoids the single point failure situation and replication improves the availability as well as performance. T-coloring method is used to assign the fragments and their replicas to improve the security.
