Cloud computing is an emerging computing premise in which consists of a virtualized pool of highly scalable computing resources and provided as an internet based computing where many organizations store, reacquire and modify data among cloud users. Major problem in cloud computing is sharing data in a multi-owner manner, while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership. By leveraging group signature and dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. The main aim is to provide secure multi-owner data sharing in dynamic groups. This poses a security challenge to the data stored inside cloud. As the result, the encryption computational cost is reduced; storage overhead and scheme are independent with the number of revoked users with rigorous proof and experiments. Load Balancing is also implemented to process the User requested job by allocating to the sub servers which will process the task by evaluating the CPU performance level.
