With the development of data intensive application, such as multimedia, data warehouse, and online analysis processing, online data is increasing rapidly, hence the need for high performance SAN (Storage Area Network) becomes more and more urgent. Currently, IPSAN, which is based on iSCSI technology, is used widely. Meanwhile, it also faces some challenges. In this paper, we point out the security problem in SAN system, and present a new secure storage model, which is based on traditional IPSAN system and takes full advantage of information hiding technology, to improve the safety of the storage system.
