PROBLEM TO BE SOLVED: To provide an advertisement access number measurement method capable of measuring the much more accurate number of accesses excluding any illegitimate access due to bot or the like.SOLUTION: An advertisement distribution server includes: a program transmission step for, when receiving an advertisement acquisition request from a client, transmitting signature content and a program to instruct signature generation as well as the content of advertisements; a signature verification key coincidence confirmation step for, when receiving a message including the signature content generated when the client executes the program and a signature and a signature verification key as well as the advertisement acquisition request, confirming whether or not the signature verification key is generated by the advertisement distribution server; a signature verification step for, when the signature verification key is generated by the advertisement distribution server, verifying whether or not the signature is the legitimate signature of the signature content by using the signature verification key; and an access number management step for, when the signature is the legitimate signature of the signature content, determining that the advertisement acquisition request is legitimate, and for increasing the number of accesses to the advertisements only by one.SELECTED DRAWING: Figure 7 【課題】ｂｏｔ等による不正アクセスを除外した、より正確なアクセス数を測定することができる広告アクセス数測定方法を提供する。【解決手段】広告配信サーバが、クライアントからの広告取得要求を受信すると広告の内容とともに署名内容と署名生成を指示するプログラムを送信するプログラム送信ステップと、クライアントがプログラムを実行することにより生成した署名内容と署名、署名検証鍵を含むメッセージを本広告取得要求とともに受信すると署名検証鍵が広告配信サーバにより生成されたものであるかを確認する署名検証鍵一致性確認ステップと、署名検証鍵が広告配信サーバにより生成されたものである場合署名検証鍵を用いて署名が署名内容の正当な署名であるかを検証する署名検証ステップと、署名が署名内容の正当な署名である場合本広告取得要求が正当なものであると判断し広告へのアクセス数を１だけ増加させるアクセス数管理ステップを含む。【選択図】図７
