Abstract: Implementing cloud computing empowers several paths for Web-based service contributions to meet diverse needs. However, the data security and privacy has become a significant issue that restricts many cloud applications. Many researchers have been trying to protect big data in cloud computing environment. Usually security mechanisms using encryption are neither efficient nor matched to the task of shielding big data in the Cloud. In this paper, we first discuss about challenge and potential solutions for protecting big data in cloud computing. Second, we propose Meta Cloud Data Storage Architecture efficiency performances.
Keywords: Cloud Computing, Big Data, MetaCloudDataStorage Architecture.
