Abstract

The present invention has an object to provide a method of managing contracts for licensed program use with which a licensor is able to confirm whether or not a contract for using a program has been properly kept by the user, as well as provide a system capable of utilizing the managing method. At the user-side (20), information on the status of utilizing the licensed program is stored as data (25), and the stored data is outputted after it is coded. Whereas, at the licensor-side (10), the coded data is inputted and decoded, thereby the licensor is able to determine the status of utilization of the program.
