Abstract:With the rapid spread and wide use of electronic information technology, network security problemsbegan to come out.This paper isfrom security issues in virtual property to consider, Firstly, We are analyzing the current security problems in the virtual property.Secondly, the electronic identity technology is briefly described. Finally, the virtual propertypreservation system of the safety countermeasures were studied and proposed a virtual property trading application which is based on the electronic identity, it is to improve the security of virtual property trading and regulate the field of system network virtual properties structure, and it is ensure safe implementation of virtual property trading. Virtual property preservationbased on electronic identity is appropriate for a variety of networking, e-commerce, online games, etc. Virtual property preservation system based on electronic identity demonstrates that the use of electronic identity technology can improve the security of virtual property trading.
Keywords:electronic identity; eID; virtual property; auditing; traceability
