ELECTRONIC TERMINAL DEVICE PROTECTION SYSTEM

摘要

There is provided an electronic terminal device protection system as follows. When participating in a service, an authentication ID and a hardware address of the terminal device used for the service are registered in a communication center. The communication center makes the terminal device download the e-tally of the authentication ID and e-tally information of the hardware address accompanying the application software. When using the service, the e-tally of the hardware address and the tally of the authentication ID which have been acquired according to the e-tally information by the terminal device are sent to the communication center. The communication center correlates the authentication ID received with the authentication ID stored and correlates the tally of the hardware address with the tally of the hardware address stored, thereby authenticating the terminal device to be connected.
