Summary:PROBLEM TO BE SOLVED: To perform display control that prevents leakage of secret information to a guest and does not obstruct user work at a terminal when limiting the display of secret information on a terminal in an open environment.SOLUTION: The user information receiving unit 13 of a server 1 receives, from terminals 10A-10I, a user information indicating whether there is a user currently using and whether secret information that is set to secret is being displayed. A guest information receiving unit 11 receives guest information indicating the position of a guest detected from sensors 3A-3D and which is an object for which secret information is kept secret. A recognition area calculation unit 14 calculates the recognition area of the guest on the basis of the guest information. A danger degree determination unit 15 determines the danger degree of a terminal on the basis of recognition area information indicting the recognition area, the user information, and the terminal information indicating the position of the terminal. A control information transmission unit 16 transmits, to the terminals 10A-10I, control information indicating a control method for controlling the display of secret information corresponding to each of the danger degrees.SELECTED DRAWING: Figure 2 【課題】オープンな環境にある端末の秘密情報の表示制限を実施する場合に、ゲストに秘密情報が漏れず、かつ、端末のユーザの作業を極力妨げない表示制御を行う。【解決手段】サーバ１のユーザ情報受信部１３は、端末１０Ａ〜１０Ｉから使用中のユーザの存否と、秘密に設定された秘密情報を表示しているか否かとを示すユーザ情報を受信する。ゲスト情報受信部１１は、センサ３Ａ〜３Ｄから検知した秘密情報の秘密の対象であるゲストの位置を示すゲスト情報を受信する。認知領域算出部１４は、ゲスト情報に基づいて、ゲストの認知領域を算出する。危険度判定部１５は、認知領域を示す認知領域情報と、ユーザ情報と、端末の位置を示す端末情報と、に基づいて、端末の危険度を判定する。制御情報送信部１６には、それぞれの危険度に対応する、秘密情報の表示を制御する制御方法を示す制御情報を端末１０Ａ〜１０Ｉに送信する。【選択図】図２
