　まず、実施例に係る情報処理装置の機能構成について説明する。図１は、実施例に係る情報処理装置の機能構成を示す図である。図１に示すように、実施例に係る情報処理装置１は、隠蔽部２と、データ記憶部３とを有する。 First, the functional configuration of the information processing apparatus according to the embodiment will be described. FIG. 1 is a diagram illustrating a functional configuration of the information processing apparatus according to the embodiment. As illustrated in FIG. 1, the information processing apparatus 1 according to the embodiment includes a concealment unit 2 and a data storage unit 3.
　隠蔽部２は、ユーザが指定したフォルダ及びファイルを隠蔽して見えないようにしたり、逆に隠蔽したフォルダ及びファイルを復元して元の場所に戻したりする。ユーザは、例えば、他人に見られたくないフォルダ及びファイルを隠蔽して保管し、自分が見るときだけ一時的に復元する。 The concealing unit 2 conceals the folder and file specified by the user so that they cannot be seen, or conversely restores the concealed folder and file to the original location. For example, the user conceals and stores folders and files that are not desired to be seen by others, and temporarily restores them only when he / she sees them.
　データ記憶部３は、非隠蔽データ記憶部３ａと隠蔽データ記憶部３ｂとを有する。非隠蔽データ記憶部３ａは、隠蔽されていないフォルダ及びファイルのデータをフォルダの階層関係の情報と共に記憶する。 The data storage unit 3 includes a non-hidden data storage unit 3a and a hidden data storage unit 3b. The non-hidden data storage unit 3a stores non-hidden folder and file data together with folder hierarchy information.
　隠蔽データ記憶部３ｂは、隠蔽を指定されたフォルダ及びファイルのデータを復元先の場所の情報と共に記憶する。隠蔽データ記憶部３ｂは、セキュリティレベルに基づいて、データを暗号化して記憶する場合と、データは暗号化することなくフォルダ及びファイルの情報だけを暗号化して記憶する場合がある。なお、データ記憶部３は、ＨＤＤ（Hard　Disk　Drive）等の不揮発性の記憶装置を用いて実現される。 The concealment data storage unit 3b stores the data of the folder and file designated to be concealed together with information on the location of the restoration destination. The hidden data storage unit 3b may encrypt and store data based on the security level, or may encrypt and store only folder and file information without encrypting the data. The data storage unit 3 is realized by using a nonvolatile storage device such as an HDD (Hard Disk Drive).
　隠蔽部２は、フォルダ及びファイルの隠蔽及び復元に必要なデータを記憶する記憶部２ａと、記憶部２ａに記憶されたデータを用いてフォルダ及びファイルの隠蔽及び復元を行う制御部２ｂとを有する。 The concealing unit 2 includes a storage unit 2a that stores data necessary for concealing and restoring folders and files, and a control unit 2b that uses the data stored in the storage unit 2a to conceal and restore folders and files. .
　記憶部２ａは、対象情報記憶部２ｃと、設定情報記憶部２ｄとを有する。対象情報記憶部２ｃは、隠蔽対象のフォルダ及びファイルの情報を記憶する。図２は、対象情報記憶部２ｃの一例を示す図である。図２に示すように、対象情報記憶部２ｃは、識別子、復元場所、種類、サイズ、隠蔽状態を隠蔽対象毎に記憶する。 The storage unit 2a includes a target information storage unit 2c and a setting information storage unit 2d. The target information storage unit 2c stores information on folders and files to be concealed. FIG. 2 is a diagram illustrating an example of the target information storage unit 2c. As illustrated in FIG. 2, the target information storage unit 2c stores an identifier, a restoration location, a type, a size, and a concealment state for each concealment target.
　識別子は、隠蔽対象のフォルダ又はファイルの名前である。復元場所は、隠蔽対象が復元されたときに格納されるフォルダへのパスである。種類は、隠蔽対象がフォルダであるかファイルであるかを示す。 The identifier is the name of the folder or file to be hidden. The restoration location is a path to a folder stored when the concealment target is restored. The type indicates whether the concealment target is a folder or a file.
　サイズは、隠蔽対象のフォルダ又はファイルの大きさである。隠蔽状態は、隠蔽対象のフォルダ又はファイルが暗号化されて隠蔽された状態にあるか否かを示し、隠蔽された状態である場合には「オン」であり、隠蔽されていない状態である場合には「オフ」である。 The size is the size of the folder or file to be concealed. The concealment state indicates whether or not the folder or file to be concealed is in an encrypted concealed state. If the concealed state is concealed, it is “on” and the concealed state is not concealed. Is "off".
　例えば、名前がDocumentである隠蔽対象は、復元されるとC:\Users\YAMADA03\Desktop\MySecretの下に格納されるフォルダであり、大きさは６７９ＭＢ（メガバイト）であり、隠蔽されていない状態にある。 For example, a hidden object whose name is Document is a folder stored under C: \ Users \ YAMADA03 \ Desktop \ MySecret when restored, and its size is 679 MB (megabytes), and is not hidden It is in.
　設定情報記憶部２ｄは、隠蔽部２に対して設定された情報を記憶する。図３は、設定情報記憶部２ｄの一例を示す図である。図３に示すように、設定情報記憶部２ｄは、ショートカットキー、セキュリティレベル、保持期間を含む情報を記憶する。 The setting information storage unit 2d stores information set for the concealment unit 2. FIG. 3 is a diagram illustrating an example of the setting information storage unit 2d. As shown in FIG. 3, the setting information storage unit 2d stores information including shortcut keys, security levels, and retention periods.
　ショートカットキーは、後述する実行ボタンを指示する代わりにユーザが入力するキーである。セキュリティレベルは、データを暗号化するか否かを示し、データを暗号化する場合には「データ」であり、データを暗号化することなく名前だけを暗号化する場合には「名前」である。保持期間は、隠蔽したデータを記憶する期間である。 The shortcut key is a key that the user inputs instead of instructing an execution button described later. The security level indicates whether or not the data is encrypted, and is “data” when the data is encrypted, and is “name” when only the name is encrypted without encrypting the data. . The retention period is a period for storing the concealed data.
　図３では、ショートカットキーとして「Ｃｔｒｌ＋Ａｌｔ＋Ｔ」が設定され、セキュリティレベルとして「名前」が設定され、保持期間として「１ヶ月」が設定されている。 In FIG. 3, “Ctrl + Alt + T” is set as the shortcut key, “Name” is set as the security level, and “1 month” is set as the retention period.
　制御部２ｂは、認証部２１と、管理部２２と、暗号化部２３と、復号化部２４と、防止部２５とを有する。認証部２１は、隠蔽部２の機能を利用するユーザの認証を行う。認証により許可されたユーザだけが隠蔽部２を利用して隠蔽対象にアクセスすることができる。 The control unit 2b includes an authentication unit 21, a management unit 22, an encryption unit 23, a decryption unit 24, and a prevention unit 25. The authenticating unit 21 authenticates a user who uses the function of the concealing unit 2. Only the user who is permitted by the authentication can access the concealment object using the concealment unit 2.
　管理部２２は、表示装置にユーザとの対話用ウィンドウを表示し、ユーザと対話して隠蔽対象の登録及び解除、隠蔽部２に対する設定等を行う。管理部２２は、表示制御部２２ａと、登録部２２ｂと、解除部２２ｃと、設定部２２ｄとを有する。表示制御部２２ａは、表示装置にユーザとの対話用ウィンドウを表示し、ユーザによる操作を受け付ける。 The management unit 22 displays a window for dialogue with the user on the display device, and performs dialogue with the user to perform registration and cancellation of the concealment target, setting for the concealment unit 2, and the like. The management unit 22 includes a display control unit 22a, a registration unit 22b, a release unit 22c, and a setting unit 22d. The display control unit 22a displays a window for interaction with the user on the display device and accepts an operation by the user.
　登録部２２ｂは、ユーザにより指定されたフォルダ又はファイルを隠蔽対象として登録する。すなわち、登録部２２ｂは、ユーザにより指定されたフォルダ又はファイルの情報を隠蔽対象として対象情報記憶部２ｃに格納する。 The registration unit 22b registers a folder or file designated by the user as a concealment target. That is, the registration unit 22b stores information on a folder or file designated by the user in the target information storage unit 2c as a concealment target.
　図４は、登録画面の一例を示す図である。認証部２１による認証が成功すると、表示制御部２２ａは、図４に示すように、対話用ウィンドウ４１を表示する。対話用ウィンドウ４１は、隠蔽用のフォルダを表示するウィンドウであり、既に隠蔽対象として登録されているフォルダ及びファイルが一覧表示される。図４において、「名前」の欄は隠蔽対象の名前を示し、「種類」の欄は隠蔽対象がフォルダ（ファイル・フォルダ）であるかファイルであるかを示し、「サイズ」の欄は隠蔽対象の大きさを示し、「隠す」の欄は隠蔽対象の隠蔽状態を示す。例えば、図４では、Secretdocという名前のファイルが隠蔽対象として登録されている。なお、対話用ウィンドウ４１は、暗号化のフォルダを表示するウィンドウであってもよく、その場合、既に暗号化対象として登録されているフォルダ及びファイルが一覧表示される。図４において、「名前」の欄は暗号化対象の名前を示し、「種類」の欄は暗号化対象がフォルダ（ファイル・フォルダ）であるかファイルであるかを示し、「サイズ」の欄は暗号化対象の大きさを示し、「隠す」の欄は暗号化対象の暗号化状態を示す。また、隠蔽部２は、フォルダ及びファイルの隠蔽を行うことなく暗号化及び復元を行う。 FIG. 4 is a diagram showing an example of a registration screen. When the authentication by the authentication unit 21 is successful, the display control unit 22a displays a dialog window 41 as shown in FIG. The dialogue window 41 is a window for displaying a folder for concealment, and a list of folders and files already registered as a concealment target is displayed. In FIG. 4, the “name” column indicates the name of the concealment target, the “type” column indicates whether the concealment target is a folder (file / folder) or a file, and the “size” column indicates the concealment target. The “hidden” column indicates the concealment state of the concealment target. For example, in FIG. 4, a file named Secretdoc is registered as a concealment target. Note that the dialog window 41 may be a window for displaying an encryption folder. In this case, a list of folders and files already registered as encryption targets is displayed. In FIG. 4, the “name” column indicates the name of the encryption target, the “type” column indicates whether the encryption target is a folder (file / folder) or a file, and the “size” column indicates The size of the encryption target is shown, and the “Hide” column shows the encryption status of the encryption target. Further, the concealment unit 2 performs encryption and restoration without concealing folders and files.
　ユーザは、対話用ウィンドウ４１内にフォルダ又はファイルをドラッグすることで隠蔽対象として登録することができる。あるいは、ユーザは、隠蔽したいフォルダ又はファイルを選択し、ファイル・フォルダの追加を指示するボタン４０を指示することで隠蔽対象として登録することができる。図４は、Documentという名前のフォルダが対話用ウィンドウ４１内にドラッグされ隠蔽対象として登録される場合を示す。 The user can register as a concealment target by dragging a folder or file into the dialog window 41. Alternatively, the user can register as a concealment target by selecting a folder or file to be concealed and instructing a button 40 for instructing addition of a file / folder. FIG. 4 shows a case where a folder named Document is dragged into the dialogue window 41 and registered as a concealment target.
　図５は、登録後の画面を示す図である。図５に示すように、登録されたDocumentの情報が登録データ一覧に表示される。図５では、Documentの隠蔽状態は「オフ」であるので、Documentは隠蔽されていない状態にある。ユーザは、隠蔽対象の「隠す」の欄にあるボタン４２を指示することで、隠蔽状態を「オフ」から「オン」、又は「オン」から「オフ」に切り替えることができる。隠蔽状態が「オフ」から「オン」になると、対話用ウィンドウ４１にドラッグされた隠蔽対象は元のフォルダから消去され、元のフォルダの表示ウィンドウ４３からアイコン４４が消去される。逆に、隠蔽状態が「オン」から「オフ」になると、元のフォルダの表示ウィンドウ４３にアイコン４４が表示される。 FIG. 5 shows the screen after registration. As shown in FIG. 5, the registered document information is displayed in the registered data list. In FIG. 5, since the document concealment state is “off”, the document is not concealed. The user can switch the concealment state from “off” to “on” or “on” to “off” by instructing the button 42 in the “hide” field to be concealed. When the concealment state is changed from “off” to “on”, the concealment object dragged to the dialog window 41 is erased from the original folder, and the icon 44 is erased from the display window 43 of the original folder. Conversely, when the concealment state changes from “on” to “off”, an icon 44 is displayed in the display window 43 of the original folder.
　登録部２２ｂは、ユーザにより隠蔽状態が「オフ」から「オン」に操作されると、隠蔽対象を暗号化して非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す。また、登録部２２ｂは、ユーザにより隠蔽状態が「オン」から「オフ」に指示されると、隠蔽対象を復号化して隠蔽データ記憶部３ｂから非隠蔽データ記憶部３ａの元のフォルダの下に移す。 When the user operates the concealment state from “off” to “on”, the registration unit 22b encrypts the concealment target and moves it from the non-concealed data storage unit 3a to the concealed data storage unit 3b. Also, when the concealment state is instructed from “on” to “off” by the user, the registration unit 22b decrypts the concealment target and moves it from the concealment data storage unit 3b to the original folder of the non-concealment data storage unit 3a. Transfer.
　図１に戻って、解除部２２ｃは、フォルダ又はファイルの隠蔽を解除する。すなわち、解除部２２ｃは、ユーザに解除を指定されたフォルダ又はファイルの情報を対象情報記憶部２ｃから削除する。また、解除部２２ｃは、ユーザに解除を指定されたフォルダ又はファイルが隠蔽されている場合には、フォルダ又はファイルを復号化して隠蔽データ記憶部３ｂから非隠蔽データ記憶部３ａの元のフォルダの下に移動する。 Referring back to FIG. 1, the release unit 22c releases the concealment of the folder or file. That is, the canceling unit 22c deletes information on the folder or file designated to be cancelled by the user from the target information storage unit 2c. In addition, when the folder or file designated to be released by the user is concealed, the canceling unit 22c decrypts the folder or file and restores the original folder of the non-hidden data storage unit 3a from the concealed data storage unit 3b. Move down.
　ユーザは、解除対象を図５に示した対話用ウィンドウ４１から選択して「登録解除」と表示されたボタン４５を指示することで、フォルダ又はファイルの隠蔽を解除することができる。また、ユーザは、「すべてを隠す」と表示されたボタン４６を指示することで、すべての隠蔽対象の状態を「オン」にすることができる。 The user can cancel the concealment of the folder or file by selecting the cancellation target from the dialog window 41 shown in FIG. 5 and instructing the button 45 displayed as “Registration cancellation”. Further, the user can turn on all the objects to be concealed by instructing the button 46 displayed as “Hide All”.
　設定部２２ｄは、ユーザの指示に基づいて隠蔽部２の設定を行う。具体的には、設定部２２ｄは、ユーザに指示されたショートカットキー、セキュリティレベル、保持期間等を設定情報記憶部２ｄに格納する。 The setting unit 22d sets the concealment unit 2 based on a user instruction. Specifically, the setting unit 22d stores, in the setting information storage unit 2d, shortcut keys, security levels, retention periods, and the like designated by the user.
　暗号化部２３は、ユーザにより隠蔽状態が「オフ」から「オン」に指示されたフォルダ又はファイルを暗号化する。暗号化部２３は、セキュリティレベルに基づいてデータを暗号化するか、又はデータを暗号化することなくフォルダ又はファイルの名前を暗号化する。 The encryption unit 23 encrypts a folder or file whose concealment state is instructed from “off” to “on” by the user. The encryption unit 23 encrypts data based on the security level, or encrypts the name of the folder or file without encrypting the data.
　復号化部２４は、ユーザにより隠蔽状態が「オン」から「オフ」に指示されたフォルダ又はファイルを復号化する。復号化部２４は、セキュリティレベルに基づいてデータを復号化するか、又はデータを復号化することなくフォルダ又はファイルの名前を復号化する。 The decryption unit 24 decrypts a folder or file whose concealment state is instructed from “on” to “off” by the user. The decrypting unit 24 decrypts the data based on the security level, or decrypts the name of the folder or file without decrypting the data.
　防止部２５は、対話用ウィンドウ４１に表示された隠蔽対象の中に隠蔽状態が「オフ」の隠蔽対象がある状態でユーザが対話用ウィンドウ４１を閉じて隠蔽部２の処理を終了した場合に、ユーザに確認することによって、隠蔽し忘れを防止する。 When the user closes the dialog window 41 and finishes the process of the concealment unit 2 in a state where there is a concealment target whose concealment state is “off” among the concealment targets displayed in the dialog window 41, the prevention unit 25 By checking with the user, forgetting to hide is prevented.
　具体的には、防止部２５は、隠蔽状態が「オフ」の隠蔽対象がある状態でユーザが対話用ウィンドウ４１を閉じた場合に、実行ボタンを表示装置に表示する。そして、ユーザが実行ボタンを指示すると、隠蔽状態が「オフ」の隠蔽対象を暗号化して非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す。 Specifically, the prevention unit 25 displays an execution button on the display device when the user closes the dialog window 41 while there is a concealment target whose concealment state is “off”. When the user designates an execution button, the concealed object whose concealment state is “off” is encrypted and transferred from the non-concealed data storage unit 3a to the concealed data storage unit 3b.
　通常、ユーザは、他人に見られたくないフォルダ又はファイルを隠蔽対象とし、本人が使用するときだけ復号化し、使用が終了すると隠蔽対象を暗号化して隠蔽部２の処理を終了する。したがって、隠蔽状態が「オフ」の隠蔽対象がある状態でユーザが対話用ウィンドウ４１を閉じた場合には、ユーザが隠蔽対象の暗号化を忘れた可能性が高い。そこで、防止部２５は、実行ボタンを表示することによって、ユーザによる隠蔽し忘れを防止する。 Normally, the user sets a folder or file that is not desired to be seen by others as a concealment target, decrypts it only when the user uses it, encrypts the concealment target when the use ends, and ends the processing of the concealment unit 2. Therefore, when the user closes the dialog window 41 while there is a concealment target whose concealment state is “off”, it is highly likely that the user has forgotten to encrypt the concealment target. Therefore, the prevention unit 25 prevents the user from forgetting to hide by displaying an execution button.
　防止部２５は、判定部２５ａと、ボタン表示部２５ｂと、実行部２５ｃとを有する。判定部２５ａは、ユーザにより対話用ウィンドウ４１が閉じられたときに、隠蔽状態が「オフ」の隠蔽対象があるか否かを判定し、ない場合には、隠蔽部２の処理を終了し、ある場合には、ボタン表示部２５ｂに実行ボタンの表示を指示する。 The prevention unit 25 includes a determination unit 25a, a button display unit 25b, and an execution unit 25c. When the dialog window 41 is closed by the user, the determination unit 25a determines whether or not there is a concealment target whose concealment state is “off”, and if not, ends the process of the concealment unit 2; If there is, the button display unit 25b is instructed to display an execution button.
　ボタン表示部２５ｂは、実行ボタンを画面右下隅に表示する。ボタン表示部２５ｂは、実行ボタンの表示後、所定の時間が経過すると、隠蔽部２の処理を終了する。実行部２５ｃは、実行ボタンがユーザにより指示されると、隠蔽状態が「オフ」の隠蔽対象を暗号化して非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す。 The button display unit 25b displays an execution button in the lower right corner of the screen. The button display unit 25b ends the process of the concealing unit 2 when a predetermined time has elapsed after the execution button is displayed. When the execution button is instructed by the user, the execution unit 25c encrypts the concealment target whose concealment state is “off” and moves it from the non-concealment data storage unit 3a to the concealment data storage unit 3b.
　図６は、隠蔽状態が「オフ」の隠蔽対象がある状態でユーザが対話用ウィンドウ４１を閉じるためのボタン４７を指示する場合の画面例を示す図である。図６に示すように、ユーザは、「隠す」の欄が「オフ」であるDocumentがある状態で、カーソルを置くと「閉じる」が近くに表示されるボタン４７を指示して対話用ウィンドウ４１を閉じる。 FIG. 6 is a diagram illustrating a screen example when the user instructs the button 47 for closing the dialog window 41 in a state where there is a concealment target whose concealment state is “off”. As shown in FIG. 6, when there is a document whose “hide” field is “off”, the user instructs the button 47 that displays “close” nearby when the cursor is placed, and displays the dialog window 41. Close.
　図７は、実行ボタンが表示された画面例を示す図である。図７に示すように、図６に示した対話用ウィンドウ４１が閉じられ、「実行する」と表示された実行ボタン４８が画面右下隅に表示される。実行ボタン４８は、画面上に表示されて、隠蔽状態が「オフ」の隠蔽対象を暗号化して非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す処理の入力を受け付ける。例えば、実行ボタン４８は、マウスカーソルで指定される、又は、指でタッチされることにより当該処理の入力を受け付ける。なお、実行ボタン４８は、「実行する」との文字を含む画像に限られない。実行ボタン４８は、カラー、グレースケール、白黒、透明な文字を含まない画像で画面上に表示されてもよい。実行ボタン４８が透明な画像である場合、実行ボタン４８が配置された領域は、当該実行ボタン４８が重ねられた壁紙等の画像が表示される。図７では、実行ボタン４８は画面右下隅に表示される。実行ボタン４８は、画面左下隅、画面右上隅、画面左上隅等の他の場所に表示されてもよい。例えば、表示装置はタッチパネルを有する。そして、タッチパネルの静電センサが、静電容量の変化量から、指（指示体の一例）が接近したか否かを検出する。さらに、ボタン表示部２５ｂが、静電センサが画面隅での接近あるいは接触を検知した場合、当該接近あるいは接触のあった画面隅に実行ボタン４８を配置する。これにより、情報処理装置１をユーザが把持している際に、実行ボタン４８を指の届く範囲に配置することができる。 FIG. 7 is a diagram showing an example of a screen on which an execution button is displayed. As shown in FIG. 7, the dialog window 41 shown in FIG. 6 is closed, and an execution button 48 displayed as “execute” is displayed in the lower right corner of the screen. The execution button 48 is displayed on the screen, and accepts an input of a process of encrypting a concealment target whose concealment state is “OFF” and transferring it from the non-concealed data storage unit 3a to the concealed data storage unit 3b. For example, the execution button 48 receives an input of the processing by being designated with a mouse cursor or being touched with a finger. The execution button 48 is not limited to an image including the characters “execute”. The execution button 48 may be displayed on the screen as an image that does not include color, grayscale, black and white, and transparent characters. When the execution button 48 is a transparent image, an image such as a wallpaper on which the execution button 48 is superimposed is displayed in the area where the execution button 48 is arranged. In FIG. 7, the execution button 48 is displayed in the lower right corner of the screen. The execution button 48 may be displayed in other places such as the lower left corner of the screen, the upper right corner of the screen, and the upper left corner of the screen. For example, the display device has a touch panel. Then, the electrostatic sensor of the touch panel detects whether or not a finger (an example of an indicator) has approached from the amount of change in capacitance. Further, when the button display unit 25b detects the approach or contact at the corner of the screen, the execution button 48 is arranged at the corner of the screen where the approach or contact has occurred. Thereby, when the user holds the information processing apparatus 1, the execution button 48 can be arranged within the reach of the finger.
　図８は、ユーザによる実行ボタン４８の指示を示す図である。ユーザにより実行ボタン４８が指示されると、隠蔽状態が「オフ」の隠蔽対象が暗号化されて非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移されて、隠蔽部２の処理が終了する。例えば、実行部２５ｃは、タッチパネルによって検出されたユーザの指が指示する位置、あるいは、マウスカーソルが指示する位置は、実行ボタン４８の領域内にあるか否かを判定する。そして、実行部２５ｃは、当該指示する位置が領域内にあると判定した場合に、隠蔽状態が「オフ」の隠蔽対象が暗号化されて非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移される。 FIG. 8 is a diagram showing an instruction of the execution button 48 by the user. When the execution button 48 is instructed by the user, the concealment object whose concealment state is “off” is encrypted and transferred from the non-concealment data storage unit 3a to the concealment data storage unit 3b, and the processing of the concealment unit 2 ends. . For example, the execution unit 25c determines whether the position indicated by the user's finger detected by the touch panel or the position indicated by the mouse cursor is within the area of the execution button 48. When the execution unit 25c determines that the designated position is within the area, the concealment target whose concealment state is “off” is encrypted and transferred from the non-concealment data storage unit 3a to the concealment data storage unit 3b. It is.
　図９は、隠蔽部２の処理が終了したときの画面を示す図である。図９に示すように、隠蔽状態が「オフ」であったDocumentが暗号化されて非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移されたため、C:\Users\YAMADA03\Desktop\MySecretからDocumentが削除されている。 FIG. 9 is a diagram showing a screen when the process of the concealment unit 2 is completed. As shown in FIG. 9, since the document whose concealment state is “off” is encrypted and transferred from the non-concealed data storage unit 3a to the concealed data storage unit 3b, from C: \ Users \ YAMADA03 \ Desktop \ MySecret Document has been deleted.
　なお、ユーザは、実行ボタン４８を指示する代わりに、ショートカットキーを入力してもよい。図１０は、ショートカットキーの登録画面の一例を示す図である。図１０では、「Ｃｔｒｌ＋Ａｌｔ＋Ｔ」がショートカットキーとして登録される。 Note that the user may input a shortcut key instead of instructing the execution button 48. FIG. 10 is a diagram illustrating an example of a shortcut key registration screen. In FIG. 10, “Ctrl + Alt + T” is registered as a shortcut key.
　次に、隠蔽部２による処理のフローについて説明する。図１１は、隠蔽部２による処理のフローを示すフローチャートである。図１１に示すように、隠蔽部２は、ユーザの認証後に、対話用ウィンドウ４１を表示し、隠蔽対象の一覧を表示する（ステップＳ１）。そして、隠蔽部２は、隠蔽対象の登録、隠蔽対象に対する復号化等ユーザの操作を受け付け（ステップＳ２）、対応する処理を行う。 Next, the processing flow by the concealment unit 2 will be described. FIG. 11 is a flowchart showing a flow of processing by the concealment unit 2. As shown in FIG. 11, after the user is authenticated, the concealing unit 2 displays a dialog window 41 and displays a list of concealment targets (step S1). Then, the concealing unit 2 receives a user operation such as registration of the concealment target and decryption of the concealment target (step S2), and performs corresponding processing.
　そして、ユーザが対話用ウィンドウ４１を閉じるためのボタン４７を指示すると、隠蔽部２は、対話用ウィンドウ４１を閉じる（ステップＳ３）。そして、隠蔽部２は、隠蔽対象の隠蔽状態がすべて「オン」であるか否かを判定し（ステップＳ４）、すべて「オン」である場合には、処理を終了する。 Then, when the user instructs the button 47 for closing the dialog window 41, the concealing unit 2 closes the dialog window 41 (step S3). Then, the concealing unit 2 determines whether or not all the concealment states of the concealment target are “on” (step S4). If all the concealment states are “on”, the process ends.
　一方、隠蔽状態が「オフ」である隠蔽対象がある場合には、隠蔽部２は、実行ボタン４８を表示する（ステップＳ５）。その後、ユーザが実行ボタン４８を指示するかショートカットキーを入力すると、隠蔽部２は、実行ボタン４８の指示又はショートカットキーを受け付ける（ステップＳ６）。 On the other hand, when there is a concealment target whose concealment state is “off”, the concealment unit 2 displays an execution button 48 (step S5). Thereafter, when the user instructs the execution button 48 or inputs a shortcut key, the concealing unit 2 receives the instruction or shortcut key of the execution button 48 (step S6).
　そして、隠蔽部２は、隠蔽状態が「オフ」であるすべての隠蔽対象について暗号化を実行し（ステップＳ７）、隠蔽対象を非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す。そして、隠蔽部２は、処理を終了する。 Then, the concealment unit 2 performs encryption for all the concealment objects whose concealment state is “OFF” (step S7), and moves the concealment object from the non-concealment data storage unit 3a to the concealment data storage unit 3b. And the concealment part 2 complete | finishes a process.
　このように、ユーザが対話用ウィンドウ４１を閉じるためのボタン４７を指示した場合、隠蔽部２は、隠蔽状態が「オフ」である隠蔽対象があると、実行ボタン４８を表示するので、ユーザによる隠蔽し忘れを防ぐことができる。なお、対話用ウィンドウ４１が暗号化のフォルダを表示するウィンドウである場合、隠蔽部２による処理のフローは、図１１のフローチャートにおいて、「隠蔽対象」を「暗号化対象」、「隠蔽状態」を「暗号化状態」に置き換えたものとなる。また、暗号化対象を非隠蔽データ記憶部３ａから隠蔽データ記憶部３ｂに移す処理は不要となる。 As described above, when the user instructs the button 47 for closing the dialog window 41, the concealing unit 2 displays the execution button 48 when there is a concealment target whose concealment state is “off”. It is possible to prevent forgetting to hide. When the dialog window 41 is a window for displaying an encryption folder, the flow of processing by the concealment unit 2 is set to “encryption target” as “encryption target” and “concealment state” in the flowchart of FIG. It is replaced with “encrypted state”. Further, the process of moving the encryption target from the non-hidden data storage unit 3a to the hidden data storage unit 3b becomes unnecessary.
　次に、設定部２２ｄによる設定処理のフローについて説明する。図１２は、設定部２２ｄによる設定処理のフローを示すフローチャートである。図１２に示すように、設定部２２ｄは、ユーザによる設定操作がショートカットキーの設定であるか否かを判定し（ステップＳ１１）、ショートカットキーの設定である場合には、ショートカットキーを設定情報記憶部２ｄに格納する（ステップＳ１２）。 Next, the flow of setting processing by the setting unit 22d will be described. FIG. 12 is a flowchart showing a flow of setting processing by the setting unit 22d. As illustrated in FIG. 12, the setting unit 22d determines whether or not the setting operation by the user is a shortcut key setting (step S11). If the setting operation is a shortcut key setting, the shortcut key is stored as setting information. Store in the part 2d (step S12).
　一方、ショートカットキーの設定でない場合には、設定部２２ｄは、ユーザによる設定操作がセキュリティレベルの設定であるか否かを判定し（ステップＳ１３）、セキュリティレベルの設定である場合には、セキュリティレベルを設定情報記憶部２ｄに格納する（ステップＳ１４）。 On the other hand, if it is not a shortcut key setting, the setting unit 22d determines whether or not the setting operation by the user is a security level setting (step S13), and if it is a security level setting, the security level is set. Is stored in the setting information storage unit 2d (step S14).
　一方、セキュリティレベルの設定でない場合には、設定部２２ｄは、ユーザによる設定操作が保持期限の設定であるか否かを判定し（ステップＳ１５）、保持期限の設定である場合には、保持期限を設定情報記憶部２ｄに格納する（ステップＳ１６）。一方、保持期限の設定でない場合には、設定部２２ｄは、ユーザの操作に対応する他の設定処理を行う（ステップＳ１７）。 On the other hand, if the setting is not a security level, the setting unit 22d determines whether or not the setting operation by the user is a setting of a retention period (step S15). Is stored in the setting information storage unit 2d (step S16). On the other hand, if the retention period is not set, the setting unit 22d performs another setting process corresponding to the user operation (step S17).
　このように、設定部２２ｄは、ユーザによる設定操作に基づいて設定情報を設定情報記憶部２ｄに格納することによって、隠蔽部２の設定を行うことができる。 Thus, the setting unit 22d can set the concealing unit 2 by storing the setting information in the setting information storage unit 2d based on the setting operation by the user.
　上述してきたように、実施例では、管理部２２が、表示装置にユーザとの対話用ウィンドウ４１を表示し、ユーザと対話して隠蔽対象の登録及び解除、隠蔽部２に対する設定等を行う。そして、対話用ウィンドウ４１に表示された隠蔽対象の中に隠蔽状態が「オフ」の隠蔽対象がある状態でユーザが対話用ウィンドウ４１を閉じて隠蔽部２の処理を終了すると、防止部２５が、実行ボタン４８を表示して、ユーザに隠蔽状態が「オフ」の隠蔽対象があることを気付かせる。 As described above, in the embodiment, the management unit 22 displays the window 41 for dialogue with the user on the display device, and performs dialogue with the user to register and release the concealment target, set the concealment unit 2, and the like. When the user closes the dialog window 41 and ends the process of the concealment unit 2 in a state where there is a concealment target whose concealment state is “off” among the concealment targets displayed in the dialog window 41, the prevention unit 25 The execution button 48 is displayed to let the user notice that there is a concealment target whose concealment state is “off”.
　そして、ユーザが実行ボタンを指示すると、防止部２５は、隠蔽状態が「オフ」の隠蔽対象を隠蔽する。したがって、隠蔽部２は、ユーザによる隠蔽し忘れを防ぐことができ、機密性の高いフォルダ及びファイルが他人に見られることを防ぐことができる。 When the user instructs the execution button, the prevention unit 25 hides the concealment target whose concealment state is “off”. Therefore, the concealment unit 2 can prevent the user from forgetting to conceal and can prevent a highly confidential folder and file from being seen by others.
　また、実施例では、防止部２５は、実行ボタン４８を表示装置の画面右下隅に表示するので、他の表示を妨げることなく実行ボタン４８を表示することができる。 In the embodiment, since the prevention unit 25 displays the execution button 48 in the lower right corner of the display device, the execution button 48 can be displayed without interfering with other displays.
　また、実施例では、管理部２２が表示装置にユーザとの対話用ウィンドウ４１を表示し、ユーザは対話用ウィンドウ４１内にフォルダ又はファイルをドラッグすることで隠蔽対象として登録する。したがって、ユーザは簡単な操作で隠蔽対象を登録することができる。 Further, in the embodiment, the management unit 22 displays the dialog window 41 with the user on the display device, and the user registers the object as a concealment object by dragging the folder or file into the dialog window 41. Therefore, the user can register the concealment target with a simple operation.
　また、実施例では、防止部２５は、ユーザによる実行ボタン４８の指示の代わりにショートカットキーの入力を受け付ける。したがって、ユーザは、画面上での操作を行うことなく隠蔽を行うことができ、画面を見ている他人に気づかれることなく隠蔽を行うことができる。 Further, in the embodiment, the prevention unit 25 receives an input of a shortcut key instead of an instruction of the execution button 48 by the user. Therefore, the user can perform concealment without performing an operation on the screen, and can perform concealment without being noticed by others viewing the screen.
　なお、実施例では、隠蔽部２について説明したが、隠蔽部２が有する構成をソフトウェアによって実現することで、同様の機能を有する隠蔽プログラムを得ることができる。そこで、隠蔽プログラムを実行する情報処理装置１のハードウェア構成について説明する。 Although the concealment unit 2 has been described in the embodiment, a concealment program having the same function can be obtained by realizing the configuration of the concealment unit 2 by software.
