A METHOD TO CONFIRM THE NORMAL USE OF A PROGRAM IN TERMS OF COMMUNICATION BETWEEN A CLIENT COMPUTER AND A SERVER COMPUTER

摘要

A method for confirming a normal operation of a user program in communication between a user computer and a server is provided to receive determined data from plural users to compare the received data, thereby confirming an abnormal operation of a user computer. A supplier(server) receives plural verification data for normal operation verification from plural user computers. The server mutually compares the received verification data. It is decided that user computers which transmit the same verification data are normal. It is decided that user computers which transmit verification data different from the same verification data are abnormal, to confirm whether programs of the user computers are normally operated. The server checks statistical periods for user program verification, and sets random data for generating statistics in case of the statistical periods.
