Abstract The huge computation power and storage capacity that are offered by cloud computing allow users to deploy applications without infrastructure investment. Storing the data remotely without control of the owner and distribution data in the cloud of computers lead to serious concern about security. Nowadays, many organizations are adopting on the cloud to share data for knowledge discovery and data mining. In recent years, security concerns in cloud were raised by many big organizations and governments. Security issue has motivated many researchers to study security issue in cloud. In this thesis, a data protection system was designed and implemented within the cloud center. This was achieved by proposing a set of algorithms. The data were analyzed into three levels according to its importance.The first stage conducted an analysis of the database using the concept of agent, where it plays a role in division of the data to two levels low and high. |
