System for protecting subscriber information and method thereof via network

PURPOSE: A system for protecting and managing subscriber information and a method thereof are provided to protect personal information by transmitting a temporary discontinuation request signal of subscriber information to each affiliated server through a communication network when a subscriber who registered in a web site as a member transmits a requesting signal of a subscriber information protection service to an operator server. CONSTITUTION: An operator server performs a new member registration of a web site user who connected through a communication network(S100). The operator server performs a subscriber member authenticating process to an affiliated server through the communication network based on subscriber information(S200). If the subscriber inputs a requesting signal of a subscriber information protection service and an address changing service to the operator server through the communication network, the operator server operates an information protection system for stopping a usage of the information and transmits a service requesting signal to each affiliated server. In addition, the affiliated servers perform a protecting service and an address changing service of subscriber information inputted from the operator server(S300). The operator server transmits result data of the protecting service and the address changing service to the subscriber terminal through the communication network(S400).
