Profile based access control model in cloud computing environment

Cloud computing is now a day a very lucrative technology due to its efficiency, cost effectiveness, flexibility, scalability and pay-per-use. But with these advantages many new problems have been introduced and some existing problems have become so much critical. One of the existing problems that have become critical in cloud environment is access control. Access control is a procedure that allows a user to access data or file from system. There are several access policies which have to be followed by the users for accessing any kind of data from a server. In cloud environment there are many access control models. In this paper a new access control model namely Profile Based Access Control Model (PrBAC) has been proposed. There are several problems for accessing data like high access time, high searching cost and problem of data redundancy. Another problem of access control models is that the Data Owner (DO) must be always online when user wants to access data from cloud server. By PrBAC all these problems are minimized.
