SYSTEM AND METHOD FOR PREVENTING ILLEGAL USE OF DEVICE

摘要

A system and method for preventing illegal use of a device are disclosed. The system for preventing illegal use of a device comprises: a device capable of using a network service through a connected network; a certification authority for performing verification of the device according to an authentication information verification request; and a management server which, if there is a request for the use of the network service from the device, requests the certification authority for the authentication information verification of the device, and if the device is judged to be an illegal device according to a result of verification received from the certification authority, restricts the use of the network service. Accordingly, when a device attempts to access for the use of a service, it is possible to prevent the use of a device judged to be illegal through an authentication information verification procedure.
