Description

  The present invention relates to an image forming apparatus and an image forming method for managing a job history for each user.

  In an image forming apparatus such as a copying machine or a multifunction peripheral, user authentication is performed and job information of an executed job is managed for each user. When the logged-in user forgets the logout operation and leaves, the other user can use the image forming apparatus as a logged-in user until the logout process is automatically executed by the image forming apparatus. In this case, there is a problem that a job executed by another user is illegally recorded in the job history as a job of a user who has forgotten the logout operation. Therefore, a technique has been proposed in which when a card used for user authentication is detected to be removed from the RFID reader, a logout process for a logged-in user is executed without a logout operation (for example, Patent Document 1). See).

  However, according to the conventional technique, it is necessary to prepare cards as many as the number of users, and there is a problem in that there is a restriction on the system configuration. For this reason, when a logged-in user forgets to log out and leaves, another technique has been required to prevent unauthorized use by other users during login.

  The present invention has been made in view of the above problems, and provides a technique capable of preventing unauthorized use by another user during login when the logged-in user forgets to log out and leaves. With the goal.

An image forming apparatus according to the present invention is an image forming apparatus that includes an authentication unit that performs user authentication and a use history management unit that manages a use history for each user. An accepting job accepting unit and an execution permitting execution of the job when it is determined that the job setting of the job accepted by the job accepting unit matches the tendency of the job setting included in the use history of the login user For the job that has not been permitted to be executed by the permission unit, the execution permission confirmation unit that confirms whether or not the logged-in user can execute the job, and the job permitted to be executed by the execution permission unit. The job that is not permitted to be executed by the execution permission unit is executed after the login user is permitted to execute the job. And a performing unit, wherein the use history management unit may manage the job information of the job executed by the job execution unit as the usage history with accepted job set by the job receiving portion.
In addition, the execution permission unit, when the job setting of the job received by the job reception unit exists more than a specific frequency in the usage history of the login user, the tendency of the job setting included in the usage history If the job setting of the job accepted by the job accepting unit does not exist in the usage history of the login user more than the specified frequency, the use is permitted. It may be determined that the job setting tendency included in the history does not match and the execution of the job is not permitted.
The job receiving unit receives a network transmission job or a facsimile transmission job, and the execution permission unit is a transmission destination set in the job setting of the network transmission job or the facsimile transmission job received by the job reception unit. However, if it does not exist in the usage history of the login user, it may be determined that it does not match the tendency of the job setting included in the usage history of the login user, and the execution of the job may not be permitted.
The job accepting unit accepts a scan job, and the execution permission unit accepts the log-in user when the storage destination is an external recording medium in the job setting of the scan job accepted by the job accepting unit. It may be determined that the job setting tendency included in the use history does not match and the execution of the job is not permitted.
In addition, the job setting of the job received by the job receiving unit comprises a fitness setting accepting unit that accepts a fitness setting that determines that the job setting included in the usage history of the logged-in user is suitable. The execution permission unit is configured to accept the setting of the job setting accepted by the job accepting unit by the fitness setting accepting unit according to a tendency of job setting included in the use history of the login user. The execution of the job may be permitted when the degree of conformity is met.
In addition, the suitability setting accepting unit sets essential items that need to be adapted to the tendency of job setting included in the use history of the login user among the setting items of the job setting accepted by the job accepting unit. The execution permission unit includes, in the usage history of the login user, the essential items received by the fitness setting reception unit among job settings of the job received by the job reception unit. The execution of the job may not be permitted if it does not match the tendency of the job setting.
In addition, the execution permission confirmation unit transmits an email confirming whether the job is not permitted to be executed by the execution permission unit to the login user to the login user, and the mail includes the login user. The job execution unit includes a link that transmits an execution permission notification indicating execution permission of the job, and the job execution unit transmits the execution permission notification via the link for the job that is not permitted to be executed by the execution permission unit. In addition, the job may be executed.
In addition, an operation unit that receives an input of an authentication number is provided, and the execution propriety confirmation unit authenticates the job that is not permitted to be executed by the execution permission unit using a short message service to the mobile phone of the login user. The job execution unit transmits the authentication number input to the operation unit for the job that has not been permitted by the execution permission unit and the authentication number transmitted by the execution permission confirmation unit. If they match, the job may be executed.
The image forming method of the present invention is an image forming method executed by an image forming apparatus that performs user authentication and manages a usage history for each user, and accepts and accepts a job to be executed in a login state. When the job setting of the job is determined to match the tendency of the job setting included in the usage history of the logged-in user, the log-in user is permitted to execute the job and the log-in user is not permitted to execute the job. The job that has been permitted to be executed is executed, the job that has not been allowed to be executed is executed after the login user has been allowed to execute, and job information of the executed job is accepted. The job history is managed together with the job setting.

  According to the present invention, when the login user forgets the logout operation and leaves, it can be confirmed whether or not the user has been illegally used by another user during the login.

  As shown in FIG. 1, the image forming apparatus 1 is a multifunction machine and is connected to a user terminal 2 such as a personal computer via a network 3 such as a LAN (Local Area Network). The image forming apparatus 1 includes an operation unit 11, a document reading unit 12, a storage unit 13, an image processing unit 14, a printing unit 15, a fax unit 16, a communication unit 17, and a control unit 18. Yes. The image forming apparatus 1 scans a document to obtain a document image, a copy job that records the document image on a recording sheet, a facsimile transmission job that transmits the document image by facsimile, and transmits the document image via a network 3 such as the Internet. Image forming operations such as a network transmission job to be performed and a print job to print a document image received via the network are executed.

  The operation unit 11 is a user interface provided with a touch panel and various operation buttons. The user operates the operation unit 11 and inputs an instruction to perform various settings of the image forming apparatus 1 and execute various functions such as image formation.

  The operation unit 11 also displays a login screen (not shown) and accepts input of user identification information via the login screen. The user identification information may be a user ID or the like.

  The document reading unit 12 includes a scanner that reads a document. The scanner includes, for example, a light source using an LED (Light Emitting Diode) or the like, and a line sensor arranged in a main scanning direction including a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), and the like, and performs sub-scanning. Scan the document while moving in the direction.

  The storage unit 13 is a storage unit such as a semiconductor memory or an HDD (Hard Disk Drive). The storage unit 13 stores, as print data, image data acquired by reading a document by the document reading unit 12, image data received from an external terminal or the like via the communication unit 17, and the like. The storage unit 13 stores various types of management information. User information 131 is stored as management information, and the usage status of the image forming apparatus 1 by the user is stored as a usage history 132. The user information 131 is stored including the user's mail address. The storage unit 13 may include a document box area for each user. The user can designate a document box as a storage destination for image data read by the document reading unit 12 or document data received via the communication unit 17.

  FIG. 2 shows an accumulation example of the usage history 132. The usage history 132 includes the user name 132a of the login user, job information 132b of the executed job, and job setting 132c received by the job receiving unit 182.

  FIG. 3 is a diagram showing details of the usage history 132 of the user A. As shown in FIG. 3, the job information 132b includes job type, color type, aggregation, duplex, transmission destination, execution date and time, and the like. The job setting 132c includes job type, color type, aggregation, duplex, transmission destination, reception date and time, and the like.

  The job type indicates the type of job executed by the user, and includes a scan job, a copy job, a facsimile transmission job, a network transmission job, a print job, and the like. Color types include black and white and color. Consolidation is a setting for consolidating and printing N pages into one page, such as 2 in 1 for consolidating and printing two pages onto one page, and 4 in 1 for consolidating and printing four pages onto one page. “Double-sided” is a setting for double-sided printing, and is “present” when double-sided printing is set, and “−” when double-sided printing is not set. In other items as well, “-” indicates that the item has not been set. The transmission destination stores a facsimile number as a transmission destination of a facsimile transmission job, a mail address as a transmission destination of a network transmission job, and the like. In addition, a scan job storage destination (an external recording medium such as a document box or a USB memory) is also stored as a transmission destination. The execution date / time is the execution date / time when the job execution unit 185 executed the job. The reception date and time is the reception date and time when the job reception unit 182 receives a job. Since a job that is not permitted to be executed by the execution permission unit 183 described later is executed after the login user is permitted to execute, there is a time difference between the reception date and time and the execution date and time.

  In addition to this, the job information 132b may include a number indicating the number of printed sheets, a toner usage amount used for printing, an image log, and the like. Further, the job setting 132c may include the number of copies to be printed, the original paper size, the paper size of the paper supply source, the user's belonging copy, and the like. Since the job information 132b is information on a job executed based on the job setting 132c, the job information 132b includes contents that overlap with the contents of the job setting 132c. Good.

  The image processing unit 14 is a unit that performs predetermined image processing on the image data. For example, image processing such as enlargement / reduction processing, gradation adjustment, and density adjustment is performed.

  The printing unit 15 is a printing unit that prints the print data stored in the storage unit 13 on a recording sheet. For example, the printing unit 15 forms a latent image on the surface of the photosensitive drum based on the image data read from the storage unit 13, performs image formation using the latent image as a toner image with toner, and records from the photosensitive drum. The toner image is transferred onto the paper, and the toner image is fixed onto the recording paper and discharged. In addition, the printing unit 15 has a function of forming toner images using toners such as cyan, magenta, yellow, and black, respectively. By superimposing these toner images and fixing them on a recording sheet, full-color printing can be performed. It corresponds.

  The communication unit 17 has a function of connecting to the Internet via a network 3 such as a LAN (Local Area Network) or transmitting / receiving various data to / from an external terminal.

  The fax unit 16 includes a modem, generates a facsimile signal from image data read by the document reading unit 12, and transmits the generated facsimile signal via a network such as a telephone line network, and a telephone line network. And a function of generating image data from the received facsimile signal.

  The control unit 18 is an information processing unit such as a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The ROM stores a control program for controlling the operation of the image forming apparatus 1.

  The CPU of the control unit 18 reads the control program stored in the ROM, develops the control program in the RAM, and executes it to control the entire apparatus according to predetermined instruction information input from the operation unit 11. Do. The control unit 18 also functions as an authentication unit 181, a job reception unit 182, an execution permission unit 183, an execution availability confirmation unit 184, a job execution unit 185, and a usage history management unit 186.

  The authentication unit 181 performs user authentication by comparing user identification information input from the operation unit 11 and the like with the user information 131. Then, when the user authentication is successful, the authentication unit 181 performs a login process, and permits the use of the image forming apparatus 1 with the authenticated user as the login user. The authentication unit 181 performs logout processing when the logout operation is accepted by the operation unit 11 or the image forming apparatus 1 has not been operated for a specific time such as 10 minutes, for example, and logs out the logged-in user. .

  The job reception unit 182 receives a scan job, a copy job, a facsimile transmission job, a network transmission job, and a print job via the operation unit 11. The user causes the operation unit 11 to display a setting screen for a job to be executed among a scan job, a copy job, a facsimile transmission job, a network transmission job, and a print job. The user can perform various job settings such as color type, aggregation, duplex, and transmission destination via the setting screen. When the user instructs execution of a job via the operation unit 11, the job reception unit 182 receives a job based on the job setting as an execution target.

  A print job is transmitted to the image forming apparatus 1 in a state where job settings are made via a printer driver installed in the user terminal 2 and is stored in the storage unit 13 until it is designated as a job to be executed by the login user. May be stored. In this case, the user may log in to the image forming apparatus 1, specify the print job transmitted from the user terminal 2 as an execution target via the operation unit 11, and instruct execution.

  The execution permission unit 183 permits the execution of the job when the job setting of the job received by the job reception unit 182 matches the tendency of the usage history 132 of the login user. For example, the execution permission unit 183 extracts the use history 132 including the same job setting 132c as the job setting received by the job receiving unit 182 from the login user use history 132. Then, the execution permission unit 183 executes the job based on the job setting received by the job reception unit 182 when the extracted usage history 132 is more than a specific frequency such as once a month or once a week, for example. Is permitted, and if the frequency is less than a specific frequency, the execution of the job may not be permitted.

  In other words, if the job setting accepted by the job accepting unit 182 is a job setting (job setting 132c that is normally used) 132c that does not exist in the usage history 132 of the logged-in user at a specific frequency or more, the job setting from the logged-in user. The job execution is permitted as if the job was accepted. In other words, when the user sets a job that is not normally used, a job based on the job setting is not permitted by the execution permission unit 183.

  The execution permission confirmation unit 184 confirms whether or not a job that is not permitted to be executed by the execution permission unit 183 is executable by the login user. For example, the execution confirmation unit 184 may create the mail 30 shown in FIG. 3 and transmit it to the login user's mail address via the communication unit 17. For example, the mail 30 has a different job setting than usual, so a message 31 indicating that a link needs to be accessed in order to execute the job, a current job setting content 32, a normal job setting content 33, and the like. The link 34 that is accessed when the execution is permitted may be described.

  The current job setting content 32 is the job setting content of a job whose execution is to be confirmed, and is the job setting content received by the job receiving unit 182. The normal job setting content 33 is a frequently used job setting 132c among the job settings 132c similar to the current job setting content 32 in the use history 132 of the login user. When the link 34 is clicked, an execution permission notification indicating that execution is permitted is input to the job execution unit 185 via the communication unit 17 for a job that is subject to execution confirmation by the execution confirmation unit 184. To do. For example, the image forming apparatus 1 may have a Web server function and acquire an execution permission notification from a login user via a browser.

  The job execution unit 185 executes a job to which an execution permission notification is input from among jobs that have been permitted by the execution permission unit 183 and jobs that have not been permitted by the execution permission unit 183.

  For the job executed by the job execution unit 185, the use history management unit 186 stores the job information 132b, which is the content of the executed job, and the job setting 132c received by the job reception unit 182 as a use history 132. 13 is stored.

  Next, the flow of the image forming process of the image forming apparatus 1 will be described in detail with reference to FIG.

  First, a login process is executed by the authentication unit 181 (s11). Specifically, when the user inputs identification information such as a user ID on the login screen displayed on the operation unit 11, the authentication unit 181 performs user authentication by comparing the input identification information with the user information 131. To do. When the input identification information matches the user information 131, the authentication unit 181 executes a login process and permits the user to use the image forming apparatus 1.

  Subsequently, the job receiving unit 182 determines whether or not a job to be executed has been received (s12). The user displays a setting screen for any one of a print job, a scan job, a copy job, a facsimile transmission job, and a network transmission job on the operation unit 11 and performs job setting via the setting screen. When the user performs a job execution operation by, for example, pressing a start button (not shown) provided on the operation unit 11, the job reception unit 182 receives a job to be executed (s12: Yes). When the user sets a job to be executed from the operation unit 11 and does not perform the execution operation, the job receiving unit 182 does not receive the job to be executed (s12: No). If the job receiving unit 182 has not received a job to be executed, the process proceeds to step s20 where it is determined whether logout processing has been executed.

  When the job reception unit 182 receives a job to be executed (s12: Yes), the execution permission unit 183 performs execution permission determination based on the use history 132 of the login user (s13). For example, in the execution permission determination, the execution permission unit 183 determines whether the job setting of the job received by the job reception unit 182 matches the tendency of the usage history 132 of the login user. The execution permission unit 183 permits the execution of this job when it matches the trend of the usage history 132, and does not permit the execution of this job when it does not match the trend of the usage history 132.

  Specifically, the execution permission unit 183 may extract the use history 132 including the same job setting 132 c as the job setting received by the job receiving unit 182 from the login user use history 132. Then, when the extracted usage history 132 exists more than a specific frequency such as once a month or once a week, the execution permission unit 183 determines the job based on the job setting received by the job reception unit 182. Execution of the job may be prohibited when the execution is permitted and the frequency is less than a specific frequency.

  For example, in the usage history 132 of the user A shown in FIG. 3, it is assumed that the user A has a tendency that the job setting 132c of the print job is set to color type: black and white, aggregation: 2 in 1, and duplex: presence. In this case, a print job received as an execution target by the job receiving unit 182 on 2017/9/7/10: 20 has a job type of color type: black and white, aggregation: 2 in 1, duplex: yes, and the login user's It matches the trend of usage history 132. Therefore, the execution of this job is permitted by the execution permission unit 183 (s14: Yes), and the job is executed by the job execution unit 185 (s17).

  As a result, the job is executed based on the job setting that matches the tendency of the usage history 132 of the login user. In this case, since the job execution check for the login user is not performed by the execution check unit 184, the job received by the job reception unit 182 is normally immediately executed by the job execution unit 185.

  On the other hand, a print job received as an execution target by the job receiving unit 182 on 2017/9/7/15: 35 has a job type of color type: color, aggregation: 2 in 1, and duplex: yes, and the color type Is “color”, it does not match the tendency of the login user usage history 132. Therefore, the execution of this job is not permitted by the execution permission unit 183 (s14: No), and the execution permission confirmation unit 184 confirms whether or not the login user can execute the job (s15).

  The execution permission confirmation unit 184 creates the mail 30 shown in FIG. 4 for confirming whether or not the login user can execute the job that has not been permitted by the execution permission unit 183. Then, the execution confirmation unit 184 transmits the created mail 30 to the login user's mail address via the communication unit 17. The logged-in user checks the mail 30 via the user terminal 2 or the like, and clicks the link 34 when permitting execution of the job.

  When the link 34 is clicked, the user terminal 2 transmits an execution permission notification indicating execution permission to the image forming apparatus 1 via a browser or the like. The link 34 may be configured to transmit an execution permission notification including a job ID for identifying a job to be executed when clicked.

  Note that if the execution of the job is not permitted, the user may leave the action for the mail 30 as it is. In addition to the link 34, a link for transmitting an execution disapproval notice that disallows job execution may be provided in the mail 30. In addition, since the job to which the execution disapproval notice is transmitted is a suspicious job setting that the logged-in user does not remember, the execution propriety confirmation unit 184 determines that the job is a suspicious job before discarding the job in s19 described later. As such, it may be notified to the IT manager by e-mail or the like.

  When the execution permission notification is transmitted (s16: Yes), the job execution unit 185 executes this job (s17). As a result, the job is executed based on the job setting that does not match the tendency of the login user usage history 132. In this case, since the execution permission confirmation unit 184 confirms whether or not the login user can execute the job, the job received by the job reception unit 182 is executed by the job execution unit 185 after the login user is permitted to execute. become.

  Subsequently, the usage history recording unit stores the job information 132b and job setting 132c of the job executed by the job execution unit 185 in the storage unit 13 as the login user usage history 132 (s18), and performs the processing in s20. Proceed.

  On the other hand, when the execution permission notification is not transmitted (s16: No), the job execution unit 185 discards the job (s19), and advances the process to s20.

  Subsequently, when the logout process is executed by the authentication unit 181 (s20: Yes), this process ends. When the logout process is not executed by the authentication unit 181 (s20: No), the process returns to s12.

  As described above, the image forming apparatus 1 according to the present embodiment is an image forming apparatus 1 that includes the authentication unit 181 that performs user authentication and the usage history management unit 186 that manages the usage history 132 for each user. In the logged-in state, the job accepting unit 182 that accepts a job to be executed and the job setting of the job accepted by the job accepting unit 182 conform to the tendency of the job setting 132c included in the use history 132 of the logged-in user. If it is determined, the execution permission unit 183 that permits the execution of the job, the execution permission confirmation unit 184 that confirms whether or not the login user can execute the job that is not permitted to be executed by the execution permission unit 183, and the execution permission unit The job permitted to be executed by 183 is executed, and the execution permission unit 183 does not allow the execution. A job execution unit 185 that executes the received job after the login user is permitted to execute, and the usage history management unit 186 receives the job information 132b of the job executed by the job execution unit 185 by the job reception unit 182. The usage history 132 is managed together with the setting 132c.

  As described above, the image forming apparatus 1 executes the job when it is determined that the job setting of the job received by the job receiving unit 182 matches the tendency of the job setting 132c included in the use history 132 of the login user. To give permission. If it is determined that the information does not match, the execution permission confirmation unit 184 confirms whether or not the login user can execute, and executes the job after the login user is permitted to execute. Therefore, even if the login user forgets the logout operation and leaves, even if the other user uses the image forming apparatus 1 before the logout process is automatically executed, the job settings set by the other user When the tendency of the job setting 132c is different, the login user can notice the unauthorized use of other users by the mail 30, and can prevent the job from being executed.

  In the above embodiment, the execution permission unit 183 determines whether the job setting of the job received by the job reception unit 182 matches the tendency of the login user's usage history 132. When the job setting 132c with high frequency is completely matched, it is determined that it matches the tendency of the use history 132 of the login user. However, the present invention is not limited to this. For example, the execution permission unit 183 uses the log-in user's usage history when the job setting of the job received by the job reception unit 182 matches a job setting with a high usage frequency with a certain degree of conformity such as 80% or more. It may be determined that it matches the tendency of 132.

  Further, as shown in FIG. 6, the operation unit 11 is provided with a fitness level setting screen (a fitness level setting reception unit) G40 that receives a setting of a fitness level that is determined to match the tendency of the login user's usage history 132 in the execution permission unit 183. It may be displayed and set for each user or collectively by the IT administrator. On the fitness level setting screen G40, by sliding the cursor 41, the fitness level for the tendency of the usage history 132 can be set between 0% (no setting) and 100% (perfect match). When it is set to 0%, it means “no setting”, and even if the job setting of the job accepted by the job accepting unit 182 is out of the tendency of the use history 132 of the login user, the job is permitted by the execution permitting unit 183. Is allowed to execute. When set to 100%, the execution permission is granted when the job setting of the job received by the job receiving unit 182 completely matches the tendency of the usage history 132, that is, when the job setting matches the frequently used job setting. The job execution is permitted by the unit 183.

  In addition, on the fitness level setting screen G40, it is possible to set a mandatory item 42 that needs to be matched with the tendency of the use history 132 of the logged-in user from among the job setting setting items received by the job receiving unit 182. The required item 42 is optional, and the checked setting item can be set as the required item 42 by checking the check box. When the setting item set as the essential item 42 is included in the setting items of the job setting of the job received by the job receiving unit 182, the execution permission unit 183 sets the job setting of the job received by the job receiving unit 182 as a whole. Even if it matches the tendency of the login user's usage history 132, if the corresponding setting item does not match in the tendency of the login user's usage history 132, the execution of the job may not be permitted.

  The user may display the fitness level setting screen G40 on the operation unit 11, set the fitness level and the essential item 42, and press the OK button B41. As a result, the execution permission unit 183 sets the job setting of the job received by the job reception unit 182 based on the fitness set on the fitness setting screen G40 and the required item 42, as the tendency of the usage history 132 of the login user. What is necessary is just to determine whether it suits.

  In addition, among the setting items of the job setting 132c, a setting item that may leak confidential information to the outside, such as a transmission destination, may be set as the required item 42 by default, and a check to select as the required item 42 is performed. For example, only an IT administrator may be allowed to remove. According to this, it is possible to prevent the possibility of confidential information being taken out by facsimile transmission, network transmission, storing scanned images in a USB memory, etc. without the knowledge of the logged-in user, and improving security. it can.

  When the job accepted by the job accepting unit 182 is a job including confidential information, the execution permission unit 183 determines that the fitness level is 100% (complete match) regardless of the fitness level set on the fitness level setting screen G40. In such a case, execution may be permitted. For example, when the job reception unit 182 receives a job for printing, copying, facsimile transmission, or network transmission of document data or image data requiring access right, a job including confidential information is received. What is necessary is just to judge that it received.

  Moreover, although the execution confirmation part 184 transmitted the mail 30 to the login user and performed execution confirmation, it is not restricted to this. For example, the executability confirmation unit 184 may transmit, for example, a random authentication number to the login user's mobile phone using SMS (Short Message Service). Then, the execution confirmation unit 184 may display an authentication screen for inputting the transmitted authentication number on the operation unit 11. When the authentication number input via the authentication screen matches the authentication number transmitted by the execution confirmation unit 184, the job execution unit 185 determines that the execution is permitted by the login user and executes the job. May be. According to this, the logged-in user can check his / her mobile phone on the spot and enter the authentication number into the operation unit 11 without returning to his / her user terminal 2 and checking the mail 30. The telephone number of the login user's mobile phone may be included in the user information 131.

  Note that the execution confirmation unit 184 may transmit the mail 30 and also transmit the authentication number using SMS. In this case, the job execution unit 185 may execute the job when the execution permission of the login user can be confirmed by either the mail 30 or the authentication number by SMS.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention.
