"In cloud computing, RBAC enables users to carry out a wide range of authorized tasks by dynamically regulating their actions according to flexible functions, relationships and constraints. This is in contrast to conventional methods of access control, which grant or revoke user access on a rigid, object-by-object basis. In RBAC, roles can be easily created, changed or discontinued as the needs of the enterprise evolve without having to individually update the privileges for every user. In this paper, the authors have added the concept of GIFT, SWAP and GAIN terms in order to pass the transactions between the users so that each user can do work effectively."
