This paper analyses data characteristics and storage requirements of E-Commerce System, finds that how to control the data storage has become an important security problem and summarizes technological characteristics, key technologies and implementation models of the current distributed data protection. Although the current research shows that using control concept and model apply to such problems, but its implementation mechanism research is still in the initial stage. This paper puts forward a kind of trusted computing-based distributed data protection technology, which provides a reference for the development of distributed data protection.
