PROBLEM TO BE SOLVED: To allow a server to detect a modified status of a client, who uses a modified basic input/output system, modified software, or pirated edition software to do illicit operation, for taking a proper action in a service such as online game offered on a network by a server.;SOLUTION: A status of a client communicating with the server is determined by issuing a challenge to the client and making the client generate a response representing the status. The server compares the response with an expected response to determine the status is expected one not. If the status is different from the expected one, the server takes a proper action such as ending the communication with the client. Desirably, the challenge includes a code segment and a parameter, and when the client executes the code segment, the client is made to generate a response.;COPYRIGHT: (C)2004,JPO
