An Analysis of Access Control Mechanism with Authentication of Anonymous user and Deduplication of Data in Decentralized Clouds

For the Key Distribution and also data administration when a course of fine grained access control on data is demanded by the users and the scaling factor must be well enough the cloud server suffers with the processing overhead. To maintain scalability, data confidentiality as well as fine graininess of access control mechanisms at the same time on the risk of uncertainty is the main issues. As based on quality of data the system provides and generates access policies and then afterward gives severs by maintaining the security and encryption of data the permission of data owner and modifier to unauthorized cloud severs by maintaining the security and encryption of data. By taking combination of decentralized key policy and attribute Based Encryption (KP-ABE) this thing can be overcome. The proposed system will be robust and
