Outsourcing data to a third-party administrative control, as is completed in cloud computing, it gives rise to security concerns. The data temper may occur due to attacks by other users and nodes within the cloud. Therefore, high-security measures are required to protect the data within the cloud. Cloud storage can allow users to store and access their files at any time, from anywhere, with any device. To ensure data security in subcontracting, the user of the data should periodically verify the integrity of the data. This document proposes to reliable and verifiable data protection scheme, supported by third parties, that uses cloud computing technology. For a better description of the protocol, first, this system presents a differentiated system model by the user and a cube data storage structure. Based on the new system model and data structure, the schema helps users verify the integrity of data uploaded or downloaded at any time and search academic data online with encrypted keywords. Data de-duplication is performed before uploading file on the cloud by SHA-256 algorithm so it reduces the storage space.
