ABSTRACT:
The utilization of various distributed contents is restricted by a simple method, its restriction can be released, and an accurate collection of fees for the contents is made possible. A client terminal30sends a request of contents (musical scores) and a key file to a server10via a communication line20.In response to the request of these, a WEB server11transmits the contents stored in a database13,and a key issuing server12transmits the key file. The WEB server11charges a fee when the key file is requested. A viewer32can only display the musical scores in the absence of the key file. With the use of the key file, however, the viewer32can print the musical scores as well. The key file is formed in accordance with a random value that is synchronized with the timing of an instruction for purchasing the contents.
