Cloud Computing is an emerging technology and it is used where computation, data manipulation and information sharing are needed. As number of Cloud users is increasing day by day, which leads to various security issues like unauthorized and unnecessary service access. To provide access control or preventing unauthorized access of data stored at Cloud Server Storage, the existing system applies cryptographic methods by sharing the decryption keys among intended authorized users or members. However, to perform these operations, existing system needs heavy computation power and resources. achieving scalability and access control simultaneously for file storage service in cloud environment is a big concern. The issues are yet not fully resolved. Our scheme proposed the solution for these issues by a mechanism that defines a package of Role based access control, Attribute based access control and security with scalable infrastructure simultaneously.
