Description

  The present invention relates to an image processing apparatus that automatically or manually sets a password for an electronic document file.

Conventionally, there is a method of storing a file with a password in order to ensure confidentiality of an electronic document file or the like. By attaching a password, a person other than the one who knows the password is prohibited from browsing, printing or editing the file.
Further, in addition to the use restriction by such password setting, there is a method of further enhancing confidentiality by performing encryption processing on the file itself (see, for example, Patent Document 1).
According to the technique disclosed in Patent Document 1, it is determined whether or not a file is to be encrypted based on a predetermined condition, and in the case of encryption, the password (access key) is determined for each predetermined condition. Can be set.

JP 2005-354198 A

However, in the conventional technique based on such a method, it is necessary to set a password for each file, which is inconvenient for a user who manages one password for each user.
For example, if there are 5 electronic document files that only the other party (Otsuko) wants to know, the user (Executive) will have an exclusive password “******” for all 5 files. It is attached to the second party. For this reason, not only can the password be set and managed by the user A, but the user who received the file can easily cancel the password.
However, according to the technique disclosed in Patent Document 1, not only the password setting side but also the receiving side increases the trouble of inputting the password over and over according to the number of files, which is troublesome for the user. It was.

Also, in a general MFP (Multifunction Peripheral), if an electronic document file stored in a USB memory is directly printed without going through a personal computer, whether or not each file is encrypted before printing is performed. This cannot be recognized by the user via the display panel or the like. In this case, it is impossible to recognize that the file is an encrypted electronic document file without looking at a print error notification generated after the print processing operation.
Therefore, unless the user recognizes in advance that the target file is an encrypted file, useless work (error analysis, error reset operation, etc.) or delay associated with an error has occurred.

  The present invention has been made in view of the above circumstances, and sets a password in association with predetermined registration information, refers to the set password, and attaches it to one or more target files. An object of the present invention is to provide an image processing apparatus that saves the trouble of setting a password every time and improves the convenience of those who use such files.

In order to achieve the above object, the image processing apparatus of the present invention attaches a password to a target file and transmits the file to a desired destination, or stores the file in a desired location, or has a password attached. An image processing apparatus that removes the use restriction through authentication of a file, the password setting means for setting a desired password in association with predetermined registration information, and the registration information in one or more target files Password reference means for attaching a password set in association with the password.
Further, the image processing method of the present invention attaches a password to a target file and transmits the file to a desired destination, or saves the file in a desired location, or through authentication of a file with a password. An image processing method for canceling the use restriction, a step of setting a desired password in association with predetermined registration information, and a password set in association with the registration information in one or more target files And a step of attaching.

  According to the image processing apparatus and the image processing method of the present invention, it is possible to improve the convenience of setting or canceling a password for an electronic document file or the like.

The configuration of an image processing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of an image processing apparatus according to an embodiment of the present invention.
As shown in FIG. 1, the image processing apparatus 1 includes a control unit 10, an image reading unit 20, a storage unit 30, an image forming unit 40, an external interface 50, an operation display unit 60, and an authentication unit 70.

The control unit 10 includes functional means realized by the cooperation of the program and the computer as each component.
The control unit 10 includes a computer constituted by control elements such as a CPU (Central Process Unit) and a chip set, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU is an arithmetic processing device that executes a program. The ROM is a non-volatile memory that stores programs and data in advance. The RAM is a memory that temporarily stores the program and data when the program is executed and uses it as a work area. The program stored in the ROM is read by the control means of the CPU, so that a command is sent to each component of the computer to perform a predetermined process.
That is, the control unit 10 comprehensively controls the following components (the image reading unit 20, the storage unit 30, the image forming unit 40, the external interface 50, the operation display unit 60, and the authentication unit 70).
Further, the control unit 10 includes functional units shown in the figure, and performs registration, reference, cancellation, and other processing of a password attached to an electronic document file such as a PDF file. Detailed description of each component will be described later.

The image reading unit 20 includes an image sensor or the like, reads a document, and acquires an image signal. The acquired image signal is output to the image forming unit 40.
Further, the image signal of the document read by the image reading unit 20 can be converted into an electronic document file and stored in the storage unit 30.

The storage unit 30 is a storage device that includes a hard disk, a nonvolatile memory, and the like. The storage unit 30 mainly stores user registration information including a login password used for user authentication, in addition to an address book and other destination tables.
The storage unit 30 has a user box area (hereinafter referred to as a box as appropriate) in which a document file can be stored for each user.

The image forming unit 40 can mainly take out an electronic document file stored in the storage unit 30 and convert it into drawing data.
The image forming unit 40 can take out an electronic document file stored in a memory card attached to the apparatus main body via the external interface 60 and convert it into drawing data.
The converted drawing data is output by an output engine (not shown).
Specifically, toner development is formed based on a latent image of bitmap data that is drawing data, and paper printing or the like is performed by a process of transferring and fixing to a paper medium or the like via an intermediate transfer member.

The external interface 50 constitutes an input / output interface that exchanges data with an external device such as a LAN port or a USB port.
In particular, in this embodiment, a memory card such as a USB memory is detachable.
For this reason, for example, by mounting the memory card to the image processing apparatus main body via the external interface 50, the PDF file stored in the memory card can be read.
The read PDF file can be printed via the image forming unit 40. This is called so-called direct printing, and an electronic document file such as a PDF file stored in a memory card can be printed only by the image processing apparatus without using a personal computer.

The operation display unit 60 includes, for example, an operation panel in which a transparent sheet is superimposed on a liquid crystal panel or the like, and has two functions of display and input.
The operation display unit 60 displays, as a display function, a predetermined notification (for example, a notification regarding an expiration date or an error notification) to the user, various kinds of information that prompts the user to perform an operation,
Further, the operation display unit 60 provides, as an input function, a means for inputting a password necessary for password setting or cancellation, a means for selecting or inputting a file transmission destination associated with the password, and the like.

The authentication unit 70 determines the legitimacy of a person who uses the image processing apparatus 1 and performs user authentication that permits the use of only the legitimate user, and prevents unauthorized use of the apparatus. is there.
The authentication unit 70 analyzes the user name, login password, etc. of the person input by the user's input operation or IC card reading function, and determines the legitimacy thereof.
For example, the login password and the input password are collated, and if they match, use of the device is permitted, and if they do not match, use of the device can be restricted (prohibited).
Note that the user name, login password, and the like used for this authentication are stored in the storage unit 30 as user registration information.

Next, the configuration of the control unit 10 shown in FIG. 1 will be described in detail for each means.
The password setting unit 101 sets a desired password in association with user information registered in an address book or the like, or user information registered in user registration information (user registration information) used for user authentication or the like.
For example, the password setting unit 101 sets a password to be referred to as a password attached to the target file (hereinafter referred to as “reference password” as appropriate). This reference password is set in association with the registration information of the user's destination.
In the present embodiment, an address book or a dedicated address book is used as registration information to be associated.
Further, the password setting unit 101 can set a reference password in association with each address in the address book or address book, and can set an expiration date of the password.

FIG. 2 is an operation panel diagram for explaining a method of associating and setting a reference password to an address book destination.
When a reference password is set as the address book destination, the operation display unit 60 first displays an “address book setting screen” 801 shown in FIG. 2A on the operation panel.
Specifically, the user selects an address (destination) of a partner (for example, Ichiro Suzuki) to whom the target file is to be transferred and calls the address information (address book setting screen). If the address information of the other party is not yet registered, it is necessary to register other general address information.

The operation display unit 60 displays a page including a user interface for setting a reference password on the operation panel. In the case of the present embodiment, it is assumed that there is an “encrypted PDF password reference” 803 on the name input page of the “address book setting screen” 801 and the user has already selected the “name” tab.
Here, the user selects “change” 804 corresponding to “encrypted PDF password reference” 803.
As a result, the operation screen on the panel transitions to a “password setting screen” 806 shown in FIG.
The user selects “set” 807 for the reference password on this screen, and then inputs a desired password “******” in the “password input” field 808 and “confirm” the password. Enter the same password “******” in the field 809.

  At this time, the operation display unit 60 displays the expiration date information 810 of the reference password on the operation panel. The expiration date can be set by the user. For example, if the expiration date for one month is set and the setting date of the reference password is August 15, 2009, the expiration date is September 15, 2009, which is one month later. (See FIG. 2 (b)).

If the user wishes to use this expiration date, the user selects “OK” 811 to return the operation screen to FIG. Next, when the user selects “Register” 805, the reference password associated with this address and its expiration date are set.
In order to change the expiration date, “change” 812 is selected on the “password setting screen” 806 shown in FIG. As a result, the operation screen changes to a “limit setting screen” 813 shown in FIG. As shown in this figure, the user can change the expiration date for each “year”, “month”, and “day”.

Further, the password setting unit 101 can set a password to be referenced in association with a destination in a dedicated destination table (hereinafter referred to as “destination book”) that is provided separately without using an address book.
FIG. 3 is an explanatory diagram for explaining a method of associating and setting a reference password to an address book.
When setting a reference password in the address book, the operation display unit 60 first displays a “reference setting screen for each address” 820 shown in FIG. 3A on the operation panel.
When registering a new destination and reference password, the user selects “new registration” 821 on this operation screen. As a result, the operation screen transitions to a “destination-specific reference setting detail screen” 824 shown in FIG.

Next, the user inputs the other party's name (for example, “Ichiro Suzuki”) and an identification symbol (for example, “1234”) in the “destination” field 825 and the desired password “ ****** "is entered, and the same password" ****** "is entered in the" confirmation "field 827. Then, by selecting “OK” 828, the destination and the reference password are set in association with each other.
Also, before or after such setting, a file transmission method corresponding to this destination is set.
For example, in FIG. 2B, three “selections” of “mail” 829, “folder” 830, and “fax” 831 are displayed, and the user selects a transmission method for this destination from among them. .

Here, when the user selects “e-mail address” 829, an e-mail address input field (not shown) appears, and the user can set the e-mail address of the other party via this input field.
Further, the user can designate a folder or the like of another apparatus in the image processing apparatus or the same network by selecting “save folder location” 830.
Further, the user can input the fax number of the other party by selecting “FAX number” 831.

The operation screen also changes to FIG. 3B by selecting “detail / edit” 822 while selecting the destination displayed in FIG. Here, it is possible to change the reference password and the destination of the already registered destination.
In addition, by selecting “delete” 823 while selecting the destination displayed in the figure, it is possible to delete the reference password and the destination of the already registered destination from the list.

An expiration date can also be set for a reference password set in association with a destination in the destination book.
In this case, when “change” 832 of the expiration date is selected in the “reference setting detail screen for each destination” 824 shown in FIG. 3B, the operation screen changes to the “limit setting screen” 833 shown in FIG. To do. Therefore, the user can change the expiration date for each “year”, “month”, and “day”.

Also, the password setting unit 101 can set the password in association with the user registration information registered in the image processing apparatus 1 instead of the password referred to the address book or the address book.
Specifically, the password setting unit 101 can set a password in association with its own user registration information used for user authentication.

FIG. 4 shows a setting screen for user registration information used for user authentication in the image processing apparatus.
Here, “user authentication” is to determine the legitimacy of the user and determine the refusal to use the image processing apparatus itself.
For this reason, as shown in FIG. 4A, in addition to “user name” 841, “user name (reading)” 842, “login user name” 843, “login password” 844, “access level” 845 are usually used. User information necessary for authentication, such as “affiliation department” 846 and “mail address” 847, is set as user registration information.

FIG. 4A shows a user registration information setting screen for the user name “Taro Yamada” displayed on the operation panel.
In this case, the user “Taro Yamada” must use the image processing function based on the access level “user” unless the predetermined login user name “yamada” and the login password “******” are input. I can't. For example, the image processing apparatus itself cannot be used if an incorrect login user name or login password is entered.
The access level indicates the usable range of the user. For example, when the access level is “user”, the person can perform processing indispensable for general business such as copying and printing. All settings and changes can be made.

In the present embodiment, an “encrypted PDF password reference” 848 and an “expiration date” 849 of the password are further displayed on the “user registration information setting screen” 840.
Here, when “change” 850 of “encrypted PDF password reference” 848 on the operation screen is selected, the operation screen changes to a “reference method setting screen” 852 shown in FIG.
As shown in FIG. 4B, the “reference method setting screen” 852 includes items of “reference password reference” 853, “reference password setting” 854, and “reference box password when using own box” 855. Is displayed.
The user can select a desired password reference setting method from among these items.

Here, when “set” 856 of “authentication password reference” 853 is selected, the login password 844 of the authentication function is set in association with the registration information of the user name “Taro Yamada”.
Also, when “set” 857 in “reference password setting” 854 is selected, a transition is made to a “password setting screen” 859 shown in FIG. Here, the user sets a reference password.

Specifically, in the “password setting screen” 859, after selecting “set” 860 for the reference password, the desired password “******” is entered in the “password” field 861, and the “confirm” In the column 862, the same password “******” is entered.
When “Set” 858 of “Refer Box Password when using Owned Box” 855 is selected, an access password for the Box assigned for each user is set in association with the registered information of the user.

  “Box” indicates a document storage area (user box) reserved for each user in the storage unit 30. When a user box is used, since user authentication is generally performed for each user box, it is usually necessary to set a password or the like. “Refer Box Password when using Owned Box” uses this password.

Also, the password setting unit 101 can change the password expiration date even when a reference password is set in the user registration information.
Specifically, by selecting “change” 851 of “expiration date” 849 shown in FIG. 4A, a transition is made to a “time limit setting screen” 863 shown in FIG. You can change the password expiration date.
In order to change to the “expiration date setting screen” 863 and change the expiration date of the password, the “authentication password reference” 853, “reference password setting” 854, or “box password when using the own box” is used. The reference password needs to be set by any of “Reference” 855.

Further, the password setting means 101 can set a password common to each member of the broadcast transmission group.
FIG. 5 is a diagram for explaining group password setting processing regarding broadcast transmission.
When setting a group password for broadcast transmission, the operation display unit 60 displays a “broadcast transmission member setting screen” 870 shown in FIG. 5A on the operation panel.
Further, a screen for registering, modifying, or deleting a member of a desired broadcast group by selecting a predetermined tab 871 is displayed.

In the case of the present embodiment, items of “group password” 872 and “reference priority mode” 874 are displayed on this screen.
Here, when the user selects “change” 873 of “group password” 872, the operation screen changes to a group password setting screen 876 shown in FIG.
On this screen, the user selects “set” 877 for the reference password, and then inputs the desired password “******” in the “password input” field 878 and the same password “ ****** "is entered in the" Confirm "field 879.

At this time, the operation display unit 60 displays the expiration date information 880 of the reference password on the operation panel.
If the user wishes to use this expiration date, the user selects “OK” 881 to return the operation screen to FIG.
In order to change the expiration date, “change” 882 of the expiration date is selected on the “group password setting screen” 876 shown in FIG. As a result, the operation screen changes to a “limit setting screen” 883 shown in FIG. As shown in this figure, the user can change the expiration date for each “year”, “month”, and “day”.

When the user selects “change” 875 in “reference priority mode” 874 on the “broadcast transmission member setting screen” 870 shown in FIG. 5A, the operation screen is displayed in “reference priority mode” in FIG. Transition to “Setting screen” 884.
On the “reference priority mode setting screen” 884, the user can select “individual priority” 885 or “group priority” 886.
When “personal priority” 885 is selected, a password set in association with each address in the address book is prioritized when referring to the password.
When “group priority” 886 is selected, the above-described group password is prioritized when referring to the password.

In other words, when broadcasting the target file to each member using the broadcast transmission function, in the “personal priority” mode, a different password is assigned to each destination for each target destination. On the other hand, file transmission is performed.
On the other hand, in the “group priority” mode, one group password is assigned to the target file, and then the file transmission is performed to each member (destination) of the broadcast transmission.

Actually, when there are many destinations for which a password is not set among members of the broadcast transmission, it is convenient to select the “group priority” mode.
In addition, it is preferable from the viewpoint of safety that a password is set in association with each member of the broadcast transmission or that the “personal priority” mode is selected.

As shown in FIG. 1, the password reference unit 102 performs processing for attaching a password set in association with the password setting unit 101 to the target file.
Specifically, it can be used only by authorized users by attaching a password to an electronic document file stored in the storage unit 30 or read by the image reading unit 20 or input via the external interface 50. As such, usage restrictions are attached.

For example, the password reference unit 102 can refer to the password set in association with the user's destination registered in the address book or the destination book and attach it to the target file.
Also, the password reference unit 102 can refer to the password set in association with the user registration information and attach it to the target file.
Further, the password reference unit 102 can attach the password input via the password input screen to the target file.
In addition, the password reference unit 102 is compatible with broadcast transmission, and can attach a password set individually or in common to a plurality of destinations to the target file.

Note that the password reference unit 102 can also prioritize the above-described password reference variations.
For example, the password reference unit 102 sets the same address in the address book (other registration information of the present invention) when the password to be referred to the address selected from the address book (one registration information of the present invention) is not set. The set reference password can be attached to the target file.
The password reference unit 102 can also add a password input by the user to the target file when a password to be referred to the address book or the destination of the address book is not set.

Further, when this password is not input, the password reference unit 102 can attach a reference password set in association with the user registration information to the target file.
Further, the password reference unit 102 can attach the reference password set in association with the user registration information to the target file only when the authentication function is functioning effectively.
In addition, such a priority in password reference is not limited to the above-mentioned order and combination, but can be freely changed according to the usage mode and configuration.

The transmission unit 103 transmits the file with the password to a predetermined destination.
Specifically, there are mail transmission to be transmitted to a mail address, SMB transmission to be transferred or stored in a shared folder, FTP transmission to an FTP server, FAX transmission to perform facsimile communication, and the like.
For example, when an arbitrary destination is selected from the address book and a transmission process is executed, a predetermined password is referred to, the reference password is attached to the file, and each file with the password is sent to the destination. Processing is done automatically.
As a result, it is possible to eliminate the annoyance that had to be manually input for each file.

The password input screen display means 104 displays a password input screen to prompt the user to input the password.
Specifically, the password input screen display unit 104 provides a password input unit for setting a password or canceling the password via the operation display unit 70.
For this reason, the user can set a reference password or remove the file usage restriction by inputting the password via these input means.

The authentication function confirmation unit 105 confirms whether or not the authentication function for authenticating the validity of the user regarding the use of the image processing apparatus 1 is functioning effectively.
Specifically, it can be confirmed whether a so-called authentication mode preset in the apparatus main body is set to ON (valid) or set to OFF (invalid).
This is because the password reference unit 102 sets a password to be referred to using user registration information registered in advance for user authentication.
Therefore, such user registration information cannot be used in an image processing apparatus that does not have an authentication function, and the process can be simplified by not referring to the password for the user registration information.

The encryption unit 106 performs an encryption process on a file to which a password is attached.
Specifically, the file data can be encrypted at the timing when the password is given by the password reference unit 102.
The storage unit 107 can store a file with a password in the storage unit 30.
That is, the image processing apparatus 1 according to the present embodiment can not only transmit a file with a password but also save the file.
The storage destination is not limited to the storage unit 30 but may be a memory card connected via the external interface 60 such as a USB memory or an SD card.
The file stored by the storage unit 107 can be transmitted to a predetermined destination or place (folder or the like) by the transmission unit 103.

The restriction release unit 108 compares the password attached to the target file with a predetermined password, and when they match, the use restriction attached to the target file (for example, file viewing, printing, editing, etc.) Bans and other restrictions).
For example, the restriction release unit 108 checks the password attached to the target file stored in the storage unit 30 or the memory card and the release password input via the input screen, and uses them when they match. The restriction can be lifted. As a result, the user can view, print or edit the file.
Further, the restriction release unit 108 can check the password attached to the target file with a reference password set in a destination such as an address book, and release the use restriction when they match.
In addition, the restriction release unit 108 can check the reference password set in association with the user registration information of itself and the password of the target file, and can release the use restriction when they match.

Further, the restriction releasing unit 108 can also give priority to the password verification described above.
For example, the restriction canceling unit 108 can collate the reference password set in association with the user registration information with the password of the target file when the cancel password is not input via the input screen.
Further, the restriction releasing unit 108 can collate the reference password set in association with the user registration information and the password of the target file only when the authentication function is functioning effectively.
Note that the restriction releasing unit 108 can also perform decryption processing of the file when the password verification matches and the target file has been subjected to encryption processing.

The reference password canceling unit 109 cancels the association between the password and the registration information when the expiration date of the password set by the password setting unit 101 has passed.
Therefore, after this association is released, the password is not automatically assigned unless association is performed again. As a result, a certain level of security regarding the password can be ensured.

The notification unit 110 notifies various information to the user. For example, if the password verification does not match, it can be notified (error notification).
In addition, when the target file is transmitted, printed, or saved, the notifying unit 110 can perform an error notification to that effect when there is no password to be referred to.

Furthermore, the notification unit 110 according to the present embodiment can perform a predetermined notification when the expiration date of the reference password is exceeded or before the expiration date.
For example, the notification unit 110 displays messages (i) to (ii) on the operation panel or the like indicating that the expiration date is near based on the following conditions (1) to (3).
(1) When the selected destination is an address book or a destination book and a reference password is set in association with the destination.
(2) When a reference password is set in the user registration information and the user logs in using the authentication function.

Then, when the expiration date is approaching under this condition, for example, the following message is displayed.
(I) In the above conditions (1) and (2), “The password expiration date (20XX / YY / ZZ) set for this destination will expire soon.”
(Ii) For the condition (3) above, “The password expiration date (20XX / YY / ZZ) set in the user registration information will soon expire.”

Further, the notification unit 110 can notify the approach of the expiration date also by a report output.
For example, when the address book is printed by a predetermined operation, the expiration date of the password set in association with other address data is printed. In this case, it is possible to improve the visibility by increasing the font size or increasing the thickness of items with an expiration date close.
Further, when a transmission result report is printed by a predetermined operation, if a transmission destination includes a password set in association with a reference password, the expiration date is printed in association with the corresponding destination. In this case, it is possible to improve the visibility by increasing the font size or increasing the thickness of items with an expiration date close.

Furthermore, the notification means 110 can notify the approach of the expiration date also by mail notification.
For example, when a reference password is set in the address book or the address book, a notification mail to that effect can be sent to a preset device administrator (the email address of the device administrator is stored in advance in the image processing apparatus main body). If registered).
In addition, when a reference password is set in the user registration information used for user authentication, a notification mail to that effect can be sent to the user's email address (the user's email address is registered in the user registration information). If so).
Note that the notification mail is preferably transmitted, for example, when the password is actually referred to when the file is transmitted or when the image processing apparatus 1 is activated.

Further, when the expiration date of the password is exceeded, the notification unit 110 notifies that fact via a display panel or the like.
The notification of exceeding can be executed, for example, at the timing and method shown below.
First, after the first notification, the association between the password and the registration information is released, but reset information indicating this is held in the memory. Thereafter, the memory is referred to at the start timing of the image processing apparatus 1, and if reset information remains, the notification that “the expiration date has expired” is again made (second notification), and the reset information is deleted from the memory. In this way, it is possible to tell the user that the password expiration date has passed.
If the reference password is set after the first notification and before the second notification, useless notification can be omitted by not performing the second notification.

Next, an image processing procedure according to the present embodiment will be described with reference to the drawings.
6 to 8 are flowcharts illustrating a password reference method according to the present embodiment.
6 and 7 are flowcharts showing a password reference method when an encrypted electronic document file is transmitted to a desired destination.
It is assumed that a password to be referred to is set in advance in association with some destinations in the address book and the destination book.
Also, it is assumed that a password to be referred to is set in association with user registration information.
It is assumed that the file destination address is input by the user and transmission is executed.

Here, the password reference unit 102 checks whether or not the input destination is registered in the registration information (S101).
When the input destination is registered in the address book (S102: YES), the password reference unit 102 confirms whether or not a reference password is set in association with the destination (S103).
When a reference password is set for the corresponding destination in the address book (S103: present), the reference password set in association with the destination is acquired (S104).

If the reference password is not set for the corresponding destination in the address book (S103: none), or if the input destination is not registered in the address book in S102 (S102: NO), the password reference means 102 It is confirmed whether there is an individual destination setting (S105).
That is, it is confirmed whether or not an input destination is registered in a dedicated address book and a reference password is set in association with the destination.

When there is an individual destination setting (S105: Yes), the password reference unit 102 acquires a reference password set for the destination (S106).
On the other hand, if there is no individual destination setting (S105: none), password information related to authentication and the like is acquired (S107).
In addition, if a password is acquired by S104 and S106, this will be confirmed as a reference password (S108). That is, the password reference unit 102 performs processing for attaching the determined reference password to the target file.
Then, the transmission unit 103 transmits the target file with the password attached to a destination designated in advance (S110).

Here, the method of “acquiring password information related to authentication and others” in S107 will be described in detail with reference to FIG.
In the method of “acquiring password information related to authentication and others”, first, the password reference unit 102 confirms whether or not a password has been input via the operation panel (operation display unit 60) (S201). Specifically, the password input screen display unit 104 displays a password input field on the operation panel. Then, it is confirmed whether or not a password has been input via the operation display unit 60.
When the input of the password is confirmed (S201: present), it is determined that there is a reference password (S202). That is, the input password is extracted as a reference password.
When the password input is not confirmed (S201: None), the authentication function confirmation unit 105 confirms whether the authentication function is set to ON or OFF (S203). That is, it is confirmed whether or not user authentication functions effectively.

  When the authentication function is functioning effectively (S203: ON), the password reference unit 102 checks whether or not the setting for referring to the authentication password is made (S204). Specifically, it is confirmed whether or not “set” 856 is selected for “authentication password reference” 853 in FIG.

When the setting for referring to the authentication password is made (S204: setting), the password reference unit 102 determines that there is a reference password (S202). That is, the authentication password is extracted as a reference password.
In S204, when the setting for referring to the authentication password is not made (S204: not set), the password reference unit 102 checks whether or not a reference password is set (S205). Specifically, it is confirmed whether or not “set” 857 is selected for “reference password setting” 854 in FIG.

When the reference password is set (S205: set), the password reference unit 102 determines that there is a reference password (S202). That is, the individually set reference password is extracted as the reference password.
If the reference password is not set (S205: not set), the password reference unit 102 checks whether or not the setting for referring to the Box password is made (S206).
Specifically, it is confirmed whether or not “Set” 858 is selected for “Refer Box Password when using Owned Box” 855 in FIG.
When the setting for referring to the Box password is made (S206: setting), the password reference unit 102 determines that there is a reference password (S202). That is, a password set in advance for accessing the Box is extracted as a reference password.

When the setting for referring to the Box password is not made (S206: not set), or when the authentication function is recognized not to be functioning effectively in S203 (S203: OFF), it is determined that there is no reference password. (S207).
Returning to FIG. 6, the password reference unit 102 determines whether or not there is a reference password (S109).

When it is determined that there is a reference password (S109: YES), the corresponding password is determined as a reference password (S108). In other words, any of the panel input password, the authentication password, the reference password, or the BOX password that is determined as “with reference password” in S202 of FIG. 7 is determined as the reference password.
Then, the transmission unit 103 transmits the target file with the determined reference password to a destination designated in advance (S110).
When it is determined that there is no reference password (S109: NO), the notification unit 110 performs an error notification indicating that there is no password to be referred to (S111). This can prompt the user to set a password.

  Note that, as in the password reference method described above, in S107, the preferential application of the panel input password (S201) is caused by the fact that the reference password is automatically set (for example, a request from the other party, etc. For this reason, the entered password cannot be attached). Therefore, this process can be eliminated or the order of this process can be changed.

Next, a procedure for printing an electronic document file stored in an external memory (memory card) will be described with reference to FIG.
Here, it is assumed that the encrypted PDF file is stored in the memory card. That is, it is assumed that some password is attached to the encrypted PDF file, and the file cannot be printed unless the same password is input.
As shown in the figure, first, the password reference unit 102 acquires password information related to authentication and the like (S301).

Specifically, the above-described processing of S201 to S207 in FIG. 7 is performed.
That is, the presence / absence of the reference password is determined, and if there is a reference password, the panel input password (see S201), the authentication password (see S204), the reference password (see S205), or the BOX password (see S206). Get one of these as a reference password.
If there is no password to be referred to, an error notification is given (see S109 and S111).

Next, the password reference unit 102 determines whether or not the reference password has been confirmed (S302). That is, it is determined whether or not a password has been acquired in S301.
When the reference password is confirmed (S302: YES), the reference password is verified (S303). Specifically, the confirmed reference password is checked against the password attached to the encrypted PDF file.

If the two passwords are matched (S303: match), the restriction release unit 108 releases the use restriction of the encrypted PDF file, and the output unit 60 executes the printing (S304).
On the other hand, when both passwords do not match (S303: mismatch), or when the reference password is not confirmed in S302 (S302: NO), the notification unit 110 gives an error notification that the password verification does not match. (S305).

As described above, according to the image processing apparatus 1 of the present embodiment, the reference password is automatically attached and transmitted when the target file is transmitted by setting the reference information in association with the destination information. be able to.
In addition, when a target file is sent or saved, the reference password is automatically attached and sent or saved by setting a reference password associated with the user information such as user registration information used for user authentication. Can do.

In addition, by using the existing address book and user registration information for associating the reference password, the reference password according to this embodiment can be easily set without providing a new registration table.
Furthermore, even in the case of broadcast transmission in which files are transmitted to a plurality of people belonging to a group all at once, there is no need to set a password for each destination, which is convenient.

Further, when browsing, printing, or editing the target file with the password attached in this way, it is possible to save the trouble of inputting the password for each file.
For example, when directly printing an electronic document file stored in a memory card, the validity can be automatically determined with reference to a password set in association with user registration information. For this reason, when a password is attached to the file, the password is automatically verified, if it matches, direct printing is automatically performed, and if it does not match, a notification to that effect is given. Therefore, unlike the prior art, it is possible to avoid the occurrence of a printing error itself, and extra labor and delay due to the printing error.

  In addition, according to the image processing apparatus according to the present embodiment, an expiration date is set for the reference password, and when the expiration date is exceeded, the association with the registration information can be canceled, so that certain confidentiality and security can be achieved. Can be secured. Also, once registered, it is convenient because it can be used until the expiration date expires. Furthermore, even when the expiration date approaches or expires, it can be conveniently communicated to the user by a predetermined method.

  Therefore, according to the image processing apparatus 1 according to the present embodiment, the operability and convenience of the person who uses the electronic document file are significantly improved as compared with the conventional technology, and further, security is ensured and its smooth use. Can be achieved.

The image forming apparatus of the present invention has been described with reference to a preferred embodiment. However, the image processing apparatus according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. It goes without saying that implementation is possible.
For example, in the above-described embodiment, not only the MFP but also a general image processing apparatus capable of outputting an electronic document file can achieve the above-described object and achieve the same operational effects.

  Further, not only when performing direct printing, but also when copying (saving) an electronic document file to an external memory, the saving process can be performed according to a procedure according to the procedure shown in FIG. In this case, for example, the present embodiment can also be applied to a usage mode in which the target file is transferred via the external memory by replacing the process of S304 with a process of “saving the electronic document file in the external memory”. .

  The present invention can be suitably used for an image processing apparatus such as an MFP or a printer.
