摘要

A mobile phone 100-1 transmits an identification number of the mobile phone 100-1 to a car navigation device 10. Next, the mobile phone 100-1 transmits a host application to the car navigation device 500. The car navigation device 500 stores the identification number and the host application. Upon receipt of a request in which an identification number is included from the car navigation device 500, the mobile phone 100-1 checks the identification number. If the number is correct, the mobile phone 100-1 transmits a guest application executable with the host application to the car navigation device 10. As a result, illegal copy of a digital content via local communication is prevented.
