Storing data on remote cloud storage makes the maintenance affordable by data owners. The reliability and trustworthiness of these remote storage locations is the main concern for data owners and cloud service providers. When multiple data owners are involved, the aspects of membership and data sharing need to be addressed. In this paper the authors proposed efficient multi owner data sharing technique over cloud storage. The proposed scheme provides privacy and complexity while handling the data sharing over cloud. The proposed technique works with improved Shamir’s secret sharing group key mechanism. In this technique data can be uploaded in to the server after the encryption of the content by the secret group key. When new member joined in the group, new granted users can directly decrypt data files uploaded without contacting with data owners.
