It is always an effective option for storing the data on cloud as it has advantages such as processing huge volume of data on user's request. But policy updating is one of challenging issue when attribute based encryption method is used for constructing schemes such as access control. Many techniques have been proposed for achieving secure data access control in any cloud storage system, but policy updating is always a problem. In this paper, a novel scheme is proposed to enable to access control by using method known as dynamic policy updating for the data in cloud. The focus of this paper is to develop dynamic policy updating method for the data which is stored in the cloud. This method will help the data owners to update the policy for the data which is stored in the cloud. The features of this method are that data owner can update the policy on his data and data will be encrypted according to the new policy and user will be able to download only if he has new policy which is not possible in existing methods. The drawback of traditional method was removed such as user revocation and method is made more efficient access control scheme policy update based on attribute. The results show that policy can be updated for the data stored in the cloud and revoked user cannot download the file. Only the data owner can update the policy for his data in the cloud other than data owner cannot do this.
