The control unit receives a password via the input unit when a plurality of numbers arranged according to a predetermined rule are detected from the manuscript image, and the input password matches the predetermined password. In this case, the image forming unit is made to form the original image on the recording medium without making a predetermined change, and a plurality of numbers arranged according to a predetermined rule are detected from the original image. , When the password is not accepted through the input unit and when the password is accepted through the input unit and the entered password does not match the predetermined password, a predetermined change is made. Then, the image forming unit is made to form the original image on the recording medium.
　本発明によれば、予め定められたパスワードを有しているユーザーは、個人情報である可能性の高い複数の数字を含む原稿画像を変更が行なわれていない状態で取得できる。したがって、個人情報の適切な使用を意図しているユーザーは原稿画像を使用できるので、全てのユーザーに対して個人情報の取得を制限する場合と比較して、ユーザーの利便性が向上する。一方、予め定められたパスワードを有していないユーザーは、予め定められた変更が行なわれた原稿画像しか取得できないので、個人情報の不適切な使用を意図しているユーザーによって、原稿画像が不適切な用途に使用されることを防ぐことができる。 According to the present invention, a user having a predetermined password can acquire a manuscript image including a plurality of numbers that are likely to be personal information in a state where the original image has not been changed. Therefore, since the user who intends to use the personal information appropriately can use the manuscript image, the convenience of the user is improved as compared with the case where the acquisition of the personal information is restricted to all users. On the other hand, a user who does not have a predetermined password can only acquire a manuscript image with a predetermined change, so that the manuscript image is not suitable for a user who intends to improperly use personal information. It can be prevented from being used for appropriate purposes.

　ユーザーは、プラテンガラスに、原稿としてクレジットカードを載置して、スタートキー１６Ａを押下したものとする。制御部１０は、決済用カード検出機能を有効に設定している状態でスタートキー１６Ａの押下を検知すると、図３Ａ及び図３Ｂに示す決済用カード検出処理の実行を開始する。制御部１０は、決済用カード検出処理において、画像読取部１１に、プラテンガラスに載置されている原稿を読取らせて、原稿画像を示す画像データ（以下、単に「原稿画像」と記す。）を生成させる（ステップＳ１０）。この場合、制御部１０は、画像読取部１１に、図７に示す原稿画像７０を生成させたものとする。 (2) Operation at the time of executing the payment card detection process It is assumed that the user places the credit card as a manuscript on the platen glass and presses the start key 16A. When the control unit 10 detects that the start key 16A is pressed while the payment card detection function is enabled, the control unit 10 starts executing the payment card detection process shown in FIGS. 3A and 3B. In the payment card detection process, the control unit 10 causes the image reading unit 11 to read the document placed on the platen glass, and the image data indicating the document image (hereinafter, simply referred to as “manuscript image”). ) Is generated (step S10). In this case, it is assumed that the control unit 10 causes the image reading unit 11 to generate the original image 70 shown in FIG. 7.
　ステップＳ１０の処理後、制御部１０は、ＯＣＲ処理を実行して、原稿画像に含まれている文字を認識し、認識された文字に基づいて、原稿画像から、予め定められた規則に従って並ぶ複数の数字が検出されるか否かを判定する（ステップＳ１１）。予め定められた規則としては、決済用カード番号を特定可能な規則であれば特に限定されないが、ここでは、制御部１０は、「4」乃至「6」のいずれかから始まる１３個又は１６個の数字、「34」又は「37」から始まる１５個の数字、「2131」又は「1800」から始まる１５個の数字、及び、「35」から始まる１６個の数字のうちのいずれかを満たすという規則を用いるものとする。 After the processing of step S10, the control unit 10 executes OCR processing to recognize the characters included in the manuscript image, and based on the recognized characters, a plurality of characters arranged from the manuscript image according to a predetermined rule. It is determined whether or not the numerical value of is detected (step S11). The predetermined rule is not particularly limited as long as it is a rule that can specify the payment card number, but here, the control unit 10 has 13 or 16 starting from any of "4" to "6". , 15 numbers starting with "34" or "37", 15 numbers starting with "2131" or "1800", and 16 numbers starting with "35" The rules shall be used.
　この場合、原稿画像７０から、「5」から始まる１６個の数字から構成される複数の数字７１が検出されるので、制御部１０は、原稿画像から、予め定められた規則に従って並ぶ複数の数字が検出されると判定し（ステップＳ１１にてＹＥＳ）、表示部１５に、図８に示す第１警告画面８０を表示させる（ステップＳ１２）。ステップＳ１２の処理後、制御部１０は、原稿画像の形成を続行するための続行指示を入力するためのキー８２、又は、原稿画像の保存を行なうための保存指示を入力するためのキー８３がタッチされるまで、続行指示を受付けていないと判定する処理（ステップＳ１３にてＮＯ）、及び、保存指示を受付けていないと判定する処理（ステップＳ１４にてＮＯ）を繰返す。 In this case, since a plurality of numbers 71 composed of 16 numbers starting with "5" are detected from the manuscript image 70, the control unit 10 determines the plurality of numbers arranged according to a predetermined rule from the manuscript image. Is detected (YES in step S11), and the display unit 15 displays the first warning screen 80 shown in FIG. 8 (step S12). After the process of step S12, the control unit 10 has a key 82 for inputting a continuation instruction for continuing the formation of the original image, or a key 83 for inputting a save instruction for storing the original image. Until it is touched, the process of determining that the continuation instruction is not accepted (NO in step S13) and the process of determining that the save instruction is not accepted (NO in step S14) are repeated.
　ユーザーは、第１警告画面８０に含まれている、決済用カード番号が検出されているおそれがあることを示すメッセージ８１を確認して、キー８２をタッチしたものとする。制御部１０は、タッチパネル１６Ｂを介して、キー８２に対するタッチ操作を検出すると、続行指示を受付けていると判定し（ステップＳ１３にてＹＥＳ）、表示部１５に、図９に示す第２認証画面９０を表示させる（ステップＳ１５）。ステップＳ１５の処理後、制御部１０は、ユーザー認証を行なうための第１指示を入力するためのキー９３、又は、ユーザー認証を行なうことなく原稿画像の形成を行なうための第２指示を入力するためのキー９４がタッチされるまで、第１指示を受付けていないと判定する処理（ステップＳ１６にてＮＯ）、及び、第２指示を受付けていないと判定する処理（ステップＳ１７にてＮＯ）を繰返す。 It is assumed that the user confirms the message 81 included in the first warning screen 80 indicating that the payment card number may have been detected, and touches the key 82. When the control unit 10 detects a touch operation on the key 82 via the touch panel 16B, it determines that the continuation instruction is accepted (YES in step S13), and the display unit 15 displays the second authentication screen shown in FIG. 90 is displayed (step S15). After the process of step S15, the control unit 10 inputs the key 93 for inputting the first instruction for performing user authentication, or the second instruction for forming the original image without performing user authentication. The process of determining that the first instruction is not accepted (NO in step S16) and the process of determining that the second instruction is not accepted (NO in step S17) until the key 94 for the purpose is touched. Repeat.
　（２－１）パスワードが入力される場合
　（２－１－１）入力されたパスワードと許可ユーザー情報のパスワードとが一致する場合
　ユーザーは、第２認証画面９０を確認し、欄９１をタッチして、タッチパネル１６Ｂを用いて、許可ユーザーのユーザー名を示す「ARIEL」という文字列を入力したものとする。制御部１０は、タッチパネル１６Ｂを介して上記入力を受付けると、表示部１５に対し、入力された文字列を欄９１に表示させる。 (2-1) When the password is entered (2-1-1) When the entered password matches the password of the permitted user information The user confirms the second authentication screen 90 and touches the field 91. It is assumed that the character string "ARIEL" indicating the user name of the authorized user is input using the touch panel 16B. When the control unit 10 receives the input via the touch panel 16B, the control unit 10 causes the display unit 15 to display the input character string in the column 91.
　ユーザーは次いで、欄９２をタッチして、タッチパネル１６Ｂを用いて、パスワードを示す「FGHIJ」という文字列を入力したものとする。制御部１０は、タッチパネル１６Ｂを介して上記入力を受付けると、表示部１５に対し、入力された文字列を欄９２に表示させる。ユーザーは、欄９１及び欄９２に表示されている入力内容を確認して、キー９３をタッチしたものとする。 Next, it is assumed that the user touches the column 92 and inputs the character string "FGHIJ" indicating the password using the touch panel 16B. When the control unit 10 receives the input via the touch panel 16B, the control unit 10 causes the display unit 15 to display the input character string in the column 92. It is assumed that the user confirms the input contents displayed in the columns 91 and 92 and touches the key 93.
　制御部１０は、タッチパネル１６Ｂを介してキー９３に対するタッチ操作を受付けると、第１指示を受付けていると判定し（ステップＳ１６にてＹＥＳ）、入力されたパスワードが、入力されたユーザー名に対応付けてＨＤＤ１８に記憶されている許可ユーザー情報のパスワードと一致するか否かを判定する（ステップＳ１８）。この場合、制御部１０は、入力されたパスワードと許可ユーザー情報のパスワードとが一致すると判定し（ステップＳ１８にてＹＥＳ）、画像形成部１２等に、予め定められた変更を加えることなく原稿画像を記録紙に形成させるための第１画像形成処理を実行させる（ステップＳ１９）。この場合、第１画像形成処理によって、図１０に示すように、原稿画像７０が、予め定められた変更を加えられることなく記録紙Ｐ１に形成される。ステップＳ１９の処理後、制御部１０は、決済用カード検出処理を終了する。 When the control unit 10 receives the touch operation for the key 93 via the touch panel 16B, it determines that the first instruction is received (YES in step S16), and the entered password corresponds to the entered user name. It is determined whether or not the password matches the password of the permitted user information stored in the HDD 18 (step S18). In this case, the control unit 10 determines that the entered password and the password of the permitted user information match (YES in step S18), and the original image without making predetermined changes to the image forming unit 12 and the like. The first image forming process for forming the image on the recording paper is executed (step S19). In this case, as shown in FIG. 10, the original image 70 is formed on the recording paper P1 by the first image forming process without making a predetermined change. After the process of step S19, the control unit 10 ends the payment card detection process.
　（２－１－２）入力されたパスワードと許可ユーザー情報のパスワードとが一致しない場合
　ユーザーは、第２認証画面９０の欄９１をタッチして、タッチパネル１６Ｂを用いて、許可ユーザーのユーザー名を示す「AMAYA」という文字列を入力したものとする。制御部１０は、タッチパネル１６Ｂを介して上記入力を受付けると、表示部１５に対し、入力された文字列を欄９１に表示させる。 (2-1-2) When the entered password and the password of the permitted user information do not match The user touches the field 91 of the second authentication screen 90 and uses the touch panel 16B to enter the user name of the permitted user. It is assumed that the character string "AMAYA" is entered. When the control unit 10 receives the input via the touch panel 16B, the control unit 10 causes the display unit 15 to display the input character string in the column 91.
　ユーザーは次いで、欄９２をタッチして、タッチパネル１６Ｂを用いて、パスワードを示す「KLMNO」という文字列を入力したものとする。制御部１０は、タッチパネル１６Ｂを介して上記入力を受付けると、表示部１５に対し、入力された文字列を欄９２に表示させる。ユーザーは、欄９１及び欄９２に表示されている入力内容を確認して、キー９３をタッチしたものとする。 Next, it is assumed that the user touches the column 92 and inputs the character string "KLMNO" indicating the password using the touch panel 16B. When the control unit 10 receives the input via the touch panel 16B, the control unit 10 causes the display unit 15 to display the input character string in the column 92. It is assumed that the user confirms the input contents displayed in the columns 91 and 92 and touches the key 93.
　制御部１０は、タッチパネル１６Ｂを介してキー９３に対するタッチ操作を受付けると、第１指示を受付けていると判定する（ステップＳ１６にてＹＥＳ）。この場合、ＨＤＤ１８は、入力されたユーザー名及びパスワードを許可ユーザー情報として記憶していないので、制御部１０は、入力されたパスワードが、許可ユーザー情報のパスワードと一致しないと判定し（ステップＳ１８にてＮＯ）、入力されたパスワードと許可ユーザー情報のパスワードとが不一致となった回数（以下、「不一致回数」と記す。）が、予め定められた回数未満であるか否かを判定する（ステップＳ２０）。 When the control unit 10 receives the touch operation for the key 93 via the touch panel 16B, it determines that the first instruction is received (YES in step S16). In this case, since the HDD 18 does not store the entered user name and password as the permitted user information, the control unit 10 determines that the entered password does not match the password of the permitted user information (in step S18). NO), it is determined whether or not the number of times that the entered password and the password of the permitted user information do not match (hereinafter referred to as "the number of times of mismatch") is less than the predetermined number of times (step). S20).
　予め定められた回数としては、特に限定されないが、ここでは、３回を用いるものとする。この場合、不一致回数は１回であるので、制御部１０は、不一致回数は予め定められた回数未満であると判定し（ステップＳ２０にてＹＥＳ）、ステップＳ１６の処理に戻る。このとき、制御部１０は、表示部１５に対し、例えば「入力内容が誤っています。」等の、ユーザー名及びパスワードの再入力を促すためのメッセージを、第２認証画面９０上に表示させてもよい。 The predetermined number of times is not particularly limited, but here, 3 times is used. In this case, since the number of mismatches is one, the control unit 10 determines that the number of mismatches is less than a predetermined number (YES in step S20), and returns to the process of step S16. At this time, the control unit 10 causes the display unit 15 to display a message on the second authentication screen 90 for prompting the display unit 15 to re-enter the user name and password, for example, "The input content is incorrect." You may.
　ここで、ユーザーはさらに、ＨＤＤ１８に許可ユーザー情報として記憶されていないユーザー名及びパスワードを入力して、キー９３をタッチするという操作を２回繰返して行なったものとする。制御部１０は、上記と同様にしてステップＳ１６乃至ステップＳ２０の動作を２回行ない、不一致回数が３回になると、不一致回数は３回未満ではないと判定して（ステップＳ２０にてＮＯ）、撮像部２２に、操作部１６を操作しているユーザーを撮像させて、撮像画像を生成させる（ステップＳ２１）。 Here, it is assumed that the user further inputs the user name and password that are not stored as the permitted user information in the HDD 18, and repeats the operation of touching the key 93 twice. The control unit 10 performs the operations of steps S16 to S20 twice in the same manner as described above, and when the number of mismatches reaches three, determines that the number of mismatches is not less than three (NO in step S20). The image pickup unit 22 is made to take an image of the user who is operating the operation unit 16 to generate an captured image (step S21).
　ステップＳ２１の処理後、制御部１０は、生成された撮像画像が添付されている電子メールを生成し、通信部２３を介して、生成された電子メールを、ＨＤＤ１８に記憶されている管理者用電子メールアドレス宛に送信する（ステップＳ２２）。ステップＳ２２の処理後、制御部１０は、表示部１５に、図１１に示す第２警告画面１１０を表示させる（ステップＳ２３）。この場合、制御部１０は、表示部１５に、ユーザーの撮像画像を管理者に送信することを示すメッセージ１１１を、第２警告画面１１０上に表示させる。 After the process of step S21, the control unit 10 generates an e-mail to which the generated captured image is attached, and the generated e-mail is stored in the HDD 18 for the administrator via the communication unit 23. It is sent to the e-mail address (step S22). After the process of step S22, the control unit 10 causes the display unit 15 to display the second warning screen 110 shown in FIG. 11 (step S23). In this case, the control unit 10 causes the display unit 15 to display a message 111 indicating that the captured image of the user is to be transmitted to the administrator on the second warning screen 110.
　ステップＳ２３の処理後、制御部１０は、画像形成部１２等に、予め定められた変更を行なって、原稿画像を記録紙に形成させるための第２画像形成処理を実行させる（ステップＳ２４）。この場合、第２画像形成処理によって、図１２に示すように、予め定められた変更として透かし画像１２１を加える変更が行なわれて、原稿画像７０が記録紙Ｐ２に形成される。透かし画像１２１としては、特に限定されないが、ここでは、「CONFIDENTIAL」という文字列を示す画像を用いるものとする。ステップＳ２４の処理後、制御部１０は、決済用カード検出処理を終了する。 After the process of step S23, the control unit 10 causes the image forming unit 12 and the like to perform a second image forming process for forming the original image on the recording paper by making predetermined changes (step S24). In this case, as shown in FIG. 12, the second image forming process makes a change to add the watermark image 121 as a predetermined change, and the original image 70 is formed on the recording paper P2. The watermark image 121 is not particularly limited, but here, an image showing the character string "CONFIDENTIAL" is used. After the process of step S24, the control unit 10 ends the payment card detection process.
　（２－２）パスワードが入力されない場合
　ユーザーは、第２認証画面９０を確認して、ユーザー名及びパスワードを入力することなく、キー９４をタッチしたものとする。制御部１０は、タッチパネル１６Ｂを介してキー９４に対するタッチ操作を受付けると、第２指示を受付けていると判定し（ステップＳ１７にてＹＥＳ）、ステップＳ２４の処理に進み、上記と同様にして、画像形成部１２等に、第２画像形成処理を実行させる。 (2-2) When the password is not entered The user confirms the second authentication screen 90 and touches the key 94 without entering the user name and password. When the control unit 10 receives the touch operation on the key 94 via the touch panel 16B, the control unit 10 determines that the second instruction is received (YES in step S17), proceeds to the process of step S24, and proceeds in the same manner as described above. The image forming unit 12 and the like are made to execute the second image forming process.
　なお、原稿画像が予め定められた規則に従って並ぶ複数の数字を含まない場合、制御部１０は、原稿画像から、予め定められた規則に従って並ぶ複数の数字が検出されないと判定し（ステップＳ１１にてＮＯ）、ステップＳ１９の処理に進み、画像形成部１２等に、第１画像形成処理を実行させる。また、ユーザーが、第１警告画面８０のキー８２をタッチすることなく、キー８３をタッチした場合、制御部１０は、保存指示を受付けたと判定し（ステップＳ１４にてＹＥＳ）、原稿画像７０の記録紙への形成を行なうことなく、原稿画像７０をＨＤＤ１８に記憶させる（ステップＳ２５）。ステップＳ２５の処理後、制御部１０は、決済用カード検出処理を終了する。 If the original image does not include a plurality of numbers arranged according to a predetermined rule, the control unit 10 determines that the plurality of numbers arranged according to the predetermined rule are not detected from the original image (in step S11). NO), the process proceeds to step S19, and the image forming unit 12 and the like are made to execute the first image forming process. Further, when the user touches the key 83 without touching the key 82 of the first warning screen 80, the control unit 10 determines that the save instruction has been accepted (YES in step S14), and the original image 70. The original image 70 is stored in the HDD 18 without forming on the recording paper (step S25). After the process of step S25, the control unit 10 ends the payment card detection process.
　上記実施形態によれば、制御部１０は、原稿画像７０から、予め定められた規則に従って並ぶ複数の数字７１を検出した場合であって、タッチパネル１６Ｂを介してパスワードを受付け、かつ、入力されたパスワードが、ＨＤＤ１８に記憶されている許可ユーザー情報のパスワードと一致する場合に、画像形成部１２等に、第１画像形成処理を実行させる。制御部１０はまた、原稿画像７０から、予め定められた規則に従って並ぶ複数の数字７１が検出される場合であって、タッチパネル１６Ｂを介してパスワードを受付けないときと、タッチパネル１６Ｂを介してパスワードを受付け、かつ、入力されたパスワードが、許可ユーザー情報のパスワードと一致しないときとには、画像形成部１２等に、第２画像形成処理を実行させる。 According to the above embodiment, when the control unit 10 detects a plurality of numbers 71 arranged in accordance with a predetermined rule from the manuscript image 70, the password is received and input via the touch panel 16B. When the password matches the password of the permitted user information stored in the HDD 18, the image forming unit 12 or the like is made to execute the first image forming process. The control unit 10 also detects a plurality of numbers 71 arranged according to a predetermined rule from the original image 70, and when the password is not accepted via the touch panel 16B and when the password is input via the touch panel 16B. When the password is accepted and the entered password does not match the password of the permitted user information, the image forming unit 12 or the like is made to execute the second image forming process.
　このように、許可ユーザー情報のパスワードを有しているユーザーは、個人情報である可能性の高い複数の数字７１を含む原稿画像７０を、透かし画像１２１が加えられていない状態で取得できる。したがって、個人情報の適切な使用を意図しているユーザーは原稿画像７０を使用できるので、全てのユーザーに対して個人情報の取得を制限する場合と比較して、ユーザーの利便性が向上する。一方、許可ユーザー情報のパスワードを有していないユーザーは、透かし画像１２１が加えられた原稿画像７０しか取得できないので、個人情報の不適切な使用を意図しているユーザーによって、原稿画像が不適切な用途に使用されることを防ぐことができる。 In this way, the user who has the password of the permitted user information can acquire the manuscript image 70 including a plurality of numbers 71 which are highly likely to be personal information in a state where the watermark image 121 is not added. Therefore, since the user who intends to use the personal information appropriately can use the manuscript image 70, the convenience of the user is improved as compared with the case where the acquisition of the personal information is restricted to all the users. On the other hand, a user who does not have a password for authorized user information can only acquire the manuscript image 70 to which the watermark image 121 is added, so that the manuscript image is inappropriate depending on the user who intends to improperly use the personal information. It can be prevented from being used for various purposes.
　なお、制御部１０は、ステップＳ１０において、画像読取部１１によって、クレジットカードを示す原稿画像７０ではなく、例えば図１３に示すような、決済用カード番号に該当するおそれのある複数の数字１３１のみを含む原稿画像１３０が生成された場合においても、原稿画像１３０から、予め定められた規則に従って並ぶ複数の数字が検出されたと判定して（ステップＳ１１にてＹＥＳ）、上記と同様の処理を実行する。この場合において、制御部１０は、ステップＳ２４の第２画像形成処理を実行する場合には、画像形成部１２等に、透かし画像１２１を加えて、原稿画像１３０を記録紙Ｐ３に形成させる。このように、原稿画像が、決済用カード自体を示す画像でなくとも、決済用カード番号に該当するおそれのある複数の数字を含んでさえいれば、第２画像形成処理が実行されるので、個人情報の漏洩を確実に防ぐことができる。 In step S10, the control unit 10 is not a manuscript image 70 showing a credit card, but only a plurality of numbers 131 that may correspond to a payment card number, as shown in FIG. 13, for example, by the image reading unit 11. Even when the original image 130 including the above is generated, it is determined that a plurality of numbers arranged according to a predetermined rule are detected from the original image 130 (YES in step S11), and the same processing as above is executed. do. In this case, when the second image forming process of step S24 is executed, the control unit 10 adds the watermark image 121 to the image forming unit 12 and the like to form the original image 130 on the recording paper P3. As described above, even if the manuscript image is not an image showing the payment card itself, the second image forming process is executed as long as it contains a plurality of numbers that may correspond to the payment card number. Leakage of personal information can be reliably prevented.
　また上記実施形態によれば、制御部１０は、不一致回数が予め定められた回数以上になった場合に、撮像部２２に、パスワードを入力したユーザーを撮像させ、通信部２３に、撮像によって生成された撮像画像を、予め定められた送信先である管理者用電子メールアドレス宛に送信させる。これによって、予め定められた送信先の管理者は、個人情報の不適切な使用を意図しているおそれのあるユーザーを示す撮像画像を取得できるので、個人情報の漏洩をより一層効果的に防ぐことができる。 Further, according to the above embodiment, when the number of mismatches becomes more than a predetermined number of times, the control unit 10 causes the image pickup unit 22 to take an image of the user who has entered the password, and causes the communication unit 23 to take an image. The captured image is sent to the administrator's e-mail address, which is a predetermined destination. As a result, the administrator of the predetermined destination can acquire the captured image showing the user who may intend to use the personal information improperly, so that the leakage of the personal information can be prevented more effectively. be able to.
　（第１変形例）
　上記実施形態では、制御部１０は、予め定められた変更として、透かし画像１２１のみを原稿画像７０に加える変更を行なったが、本発明はそのような実施形態に限定されない。例えば、制御部１０は、予め定められた変更として、透かし画像１２１とともに、検出された複数の数字のうちの少なくとも一部を塗りつぶしによって隠すための塗りつぶし画像を、原稿画像７０に加える変更を行なってもよい。制御部１０はまた、予め定められた変更として、塗りつぶし画像のみを原稿画像７０に加える変更を行なってもよい。 (First modification)
In the above embodiment, the control unit 10 makes a change to add only the watermark image 121 to the original image 70 as a predetermined change, but the present invention is not limited to such an embodiment. For example, the control unit 10 makes a change to add to the original image 70, as a predetermined change, a filled image for concealing at least a part of the detected plurality of numbers by filling, together with the watermark image 121. May be good. The control unit 10 may also make a change to add only the filled image to the original image 70 as a predetermined change.
　図１４は、予め定められた変更を行なって形成された原稿画像の一例を示す図である。例えば、制御部１０は、第２画像形成処理において、画像形成部１２等に、予め定められた変更として、透かし画像１２１と、複数の数字７１を構成する１６個の数字のうちの１２個の数字を隠す塗りつぶし画像１４１とを加えて、原稿画像７０を記録紙Ｐ４に形成させる。このように、原稿画像７０に塗りつぶし画像１４１を加えることによって、許可ユーザー情報のパスワードを有していないユーザーは、複数の数字７１を取得できないので、個人情報の不適切な使用を意図しているユーザーによって、個人情報が不適切な用途に使用されることを確実に防ぐことができる。 FIG. 14 is a diagram showing an example of a manuscript image formed by making predetermined changes. For example, in the second image forming process, the control unit 10 changes the image forming unit 12 and the like to the watermark image 121 and 12 of the 16 numbers constituting the plurality of numbers 71 as predetermined changes. The original image 70 is formed on the recording paper P4 by adding the filled image 141 that hides the numbers. By adding the filled image 141 to the manuscript image 70 in this way, a user who does not have a password for the permitted user information cannot obtain a plurality of numbers 71, and thus intends to improperly use the personal information. It is possible to surely prevent the personal information from being used for inappropriate purposes by the user.
　（第２変形例）
　制御部１０はまた、予め定められた変更として、透かし画像１２１のみを原稿画像７０に加える変更を行なったが、本発明はそのような実施形態に限定されない。例えば、制御部１０は、予め定められた変更として、検出された「5587 3540 0123 4567」という複数の数字７１を、予め定められた他の複数の数字に置換える変更を、原稿画像７０に行なってもよい。予め定められた他の複数の数字としては特に限定されないが、例えば、「1111 2222 3333 4444」等である。 (Second modification)
The control unit 10 has also made a modification to add only the watermark image 121 to the original image 70 as a predetermined change, but the present invention is not limited to such an embodiment. For example, the control unit 10 makes a change in the manuscript image 70 to replace the detected plurality of numbers 71 of "5587 3540 0123 4567" with other predetermined numbers as predetermined changes. You may. The other plurality of predetermined numbers are not particularly limited, but are, for example, "1111 2222 3333 44 44" and the like.
　このように、複数の数字７１を予め定められた他の複数の数字に置換えることによって、許可ユーザー情報のパスワードを有していないユーザーは、複数の数字７１を取得できないので、個人情報の不適切な使用を意図しているユーザーによって、個人情報が不適切な用途に使用されることを確実に防ぐことができる。なお、制御部１０はさらに、原稿画像７０から氏名を示す複数の文字及び有効期限を示す複数の数字のうちの少なくともいずれかが検出される場合、氏名を示す複数の文字についても予め定められた他の氏名を示す複数の文字に置換える変更を行なってもよいし、有効期限を示す複数の数字についても、予め定められた他の有効期限を示す複数の数字に置換える変更を行なってもよい。 In this way, by substituting the plurality of numbers 71 with other predetermined numbers, a user who does not have the password of the permitted user information cannot acquire the plurality of numbers 71, so that the personal information cannot be obtained. It is possible to ensure that personal information is prevented from being used for inappropriate purposes by a user who intends to use it properly. In addition, when at least one of a plurality of characters indicating the name and a plurality of numbers indicating the expiration date is detected from the manuscript image 70, the control unit 10 is also predetermined for the plurality of characters indicating the name. You may make changes to replace multiple characters indicating other names, or you may make changes to replace multiple numbers indicating the expiration date with multiple numbers indicating other predetermined expiration dates. good.
　（第３変形例）
　上記実施形態では、制御部１０は、不一致回数が予め定められた回数以上になった場合に、通信部２３に、管理者用電子メールアドレス宛に撮像画像を送信させる処理を行なったが、本発明はそのような実施形態に限定されない。例えば、制御部１０は、上記した撮像画像の送信に加えて、画像形成部１２等に、撮像画像を記録紙に形成させてもよい。 (Third modification example)
In the above embodiment, the control unit 10 performs a process of causing the communication unit 23 to transmit the captured image to the administrator's e-mail address when the number of mismatches exceeds a predetermined number of times. The invention is not limited to such embodiments. For example, in addition to the transmission of the captured image described above, the control unit 10 may have the image forming unit 12 or the like form the captured image on the recording paper.
