Due to rapid development in cloud computing and integration of new tools that enhances the development in cloud computing application, but cloud computing is in child state so that cloud security is often required. Many organizations want to store their confidential sensitive data in cloud in order to reduce capital expanses. Traditional way is to store data in encrypted format against the untrusted cloud service provider (CSP). The key problem is to maintain different organization structure and establishing unaccess control policy (UCP) for those confidential encrypted data, when users are no longer employee of organization. This paper aims to solve problem for supporting different organization structure and maintain their hierarchy of various users in the organizations, maintain record of employees .Our system is having integrating key feature of Hierarchical attribute based encryption (HABE) and cipher text policy attribute based encryption (CP-ABE) system, so as not only achieved high performance and fine grained access, user revocation scheme when user are not longer employee of organization.
