System and method for data safe exchange

The invention provides a system and a method for data safe exchange. The system comprises an inner network data exchange module and an outer network data exchange module. The inner network data exchange module comprises a management configuration unit and an inner network data exchange unit. The outer network data exchange module comprises an outer network data exchange unit. The management configuration unit directly establishes the inner network data exchange unit and an inner network data server. The outer network data exchange unit is in relative configuration with an outer data server. According to the system and the method for the data safe exchange, under the premise that data exchange safety among networks is guaranteed, the current situation that data exchange among the networks is achieved by means of depending on a client side with client side software installed is eliminated.
