Enhanced Retreat of Cloud Storage Data users by Using Improved Data Access Control Scheme for Multi-Authority Cloud Storage

2015 International Journal of Science and Research (IJSR)  
The number of user in cloud computing are increasing tremendously due to its advantage of providing flexible storage requirement. The users are started to share their sensitive information through the cloud due to its nature of providing convenience to users. The security of the data has to be assured to the users when storing their details into the cloud server. In the existing work an expressive, efficient and revocable data access control scheme for multi-authority cloud storage systems is

The users those who are having matching attributes as in the access policy defined in the cipher text can retrieve the entire data content. It aims to allow the users with eligible attributes to decrypt the entire data stored in the cloud server. However it cannot limit the users from accessing the data's which are not accessible to them. That is it cannot limit the data access control to the authorized users. In this work a novel algorithm namely Privacy enhanced Data Access Control Scheme is proposed to overcome the problem exist in the existing work. In the existing work data access control is limited to the user from the unauthorized users whereas in the proposed algorithm aim to limit the data access control to the authorized user.
