Privacy preserving model in cloud environment

There is consistent growth in the field of cloud computing. These services can be utilized on pay-per-use basis. The problem of disclosure of privacy occurs when data is exchanged in the cloud. The idea is to build privacy preserving model of storage, where data sharing services can update and control the access and usage of their shared data. In cloud computing, privacy preserving is an important issue and it needs to be considered at every phase of design. The paper proposes a metadata based storage methodology along with an encryption technique to provide additional security. This would serve as a helping note in strengthening the privacy preserving approaches in cloud computing.
