Abstract
A server device and a client device are connected through the Internet and the server device provides predetermined information on demand by the client device. The client device starts obtaining time when it displays predetermined information provided by the server device and stops obtaining time when a response to displayed predetermined information is input. That is, the client device obtains the time period between a display of predetermined information and an input of the response. The client device sends the obtained time period to the server device through the Internet. The server device certifies the received time period. At the time of certifying, the server device checks if the time period data and the program for obtaining the time period are improperly altered or not.
