NETWORK SECURITY SYSTEM

摘要

Ordering information is received by the server 3 through the network 1, when the order is placed by a user. The received data storage means 6 stores data with an external format 4 the server received. The received data format conversion means 7 converts data with an external format 4 stored in the received data storage means 6 to data with an internal format 5, and must be stored in the received process data storage means 8. The host computer 10 administrates the orders using the data with the internal format 5 stored in the received process data storage means. By the construction stated above, fraudulent data can be eliminated as the received data format conversion means 7 can convert data with an external format 4 to data with reliable internal format 5.
