Multi Owner Data Sharing with Privacy Preserving in Cloud Security Mediator

Cloud computing provide a promising pattern for data security services and high-quality data services .it provides various solution for sharing data with security concerns from dynamic resources in multi pattern based on storing and sharing have several issues from the multiple data owners are involved, the aspects of membership and data sharing need to be addressed. In this paper we proposed an efficient multi owner data sharing technique over cloud storage. The proposed scheme provides privacy and complexity while handling the data sharing over cloud from authorized data holders also it user third party access rights sharing group key mechanism encryption with two round access key technique. 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 with key accessible technique. Our security proof and performance analysis shows that Anomy Control is both secure and efficient for cloud computing environment.
