A trace center apparatus comprising a tracer generation and registration part issuing a tracer identification number that uniquely identifies a content residing on a different computer and also uniquely identifies a tracer, generating a tracer program having the function of reporting identification information of a computer on which a content resides and the tracer identification number to a trace center while holding the trace identification number, and registering the tracer program with the trace center.
A method for enabling a content to be traced, the method comprising the steps of:
- issuing a tracer identification number uniquely identifying a content residing on a different computer and also uniquely identifying a tracer;
- generating a tracer program including the function of reporting identification information of a computer on which the content resides and the trace identification number to a trace center while holding the tracer identification number;
- and
- registering the tracer program with the trace center.
