Abstract
A user is permitted to execute a predetermined program only within a limited time that corresponds to a period wherein the user maintains a valid contract for a connection with a specific network provider. When a user activates or executes a program that is provided by a network provider, or an entity having a tie-up with the network provider, the user must refer to a licensing key that can halt at least a part of the functions of the program when a predetermined licensing (halting) condition is matched. The licensing key can be updated by making a connection with the network provider.
