Abstract
A system that executes content like music and moving pictures, and protects rights like copyright, working on a configuration of a mobile information terminal and an external device is provided. A mobile information terminal acquires a right (ticket) to execute content. An external device of higher performance, compared with a mobile information terminal, executes content after receiving the ticket from a mobile information terminal. Though content and ticket can move freely in a system, once the content is executed, an identifier for identifying the mobile information terminal that demanded the execution of content is liked with the ticket. It is this mobile information terminal that can use the same ticket again.
