Implementation of Robust Multi Owner Multi Group Data Security Algorithm for Cloud Environment

Cloud computing is a kind of centralized database where number of clients accumulate their data, recover data and possibly adjust data. Concerns of sensitive information on cloud potentially cause privacy problems. Data encryption protects data security to some extent so have to use Blowfish-AES encryption and zip an encrypted files before uploading for reduce memory space. Multi owner scheme (MOS) for data sharing by supporting dynamic groups efficiently so that revocation can be easily achieved. This guarantees any member in a group to anonymously utilize the cloud resource, so security issues rapidly arises when group owner adopted this Multi owner scheme.
