Abstract: A method and system for providing territory control in a computer system is disclosed. In one aspect, the method and system include allowing a signal capable of including a first signal and a second signal to be received. The first signal includes a first portion and a second portion that is interspersed with the first portion. The second signal determines how the second portion is interspersed with the first portion. The method and system also include checking the first portion of the first signal to determine if the first portion corresponds to a key, continuing normal operation of the computer system if the first portion corresponds to the key and taking an action if the first portion does not correspond to the key. In another aspect, the computer system uses a data medium. In this aspect, the method and system include using the data medium to provide a first key and a signal capable of including a first and a second signal.
