  FIG. 8 is a schematic diagram illustrating an example of a code pattern of multifunction machine information. The code pattern of the multifunction machine information is obtained by coding multifunction machine information (device information) necessary for specifying the multifunction machine 1, and is a barcode, a QR code (registered trademark), or the like. The MFP information includes network identification information such as a host name, an IP address, and a MAC address assigned to the MFP 1, a MFP ID (serial number), a name assigned to the MFP 1, and the MFP 1 Any information can be used as long as it is information that can identify the multifunction device 1, such as information on the installation location (convenience store), and any one or a plurality of these information can be used. The code pattern may be displayed on the operation panel 11 (display unit 11b) of the multi function device 1, or may be printed on paper or the like and attached to an appropriate position on the multi function device 1.

  The user operates the operation panel 32 of the information processing terminal 3, inputs his / her user ID and password, and the control unit (instructor information acquisition unit) 30 is connected to the user via the operation panel 32 (input unit 32a). An ID and a password (instructor information for specifying the instructor) are acquired. Next, the user operates the shooting button, and the control unit (apparatus information acquisition unit) 30 switches to the imaging mode by the imaging unit 33, captures a code pattern as shown in FIG. ) To get. After photographing the code pattern, the user operates the print button and requests the authentication server 2 to execute printing by a desired multifunction device 1. The control unit 30 of the information processing terminal 3 transmits the acquired code pattern information, user ID and password (hereinafter collectively referred to as authentication information) to the authentication server 2 via the communication unit (sending unit) 34 ( S2).

The control unit 20 of the authentication server 2 acquires code pattern information and authentication information via the communication unit 22, and the user authentication unit (authentication unit) 26 performs an authentication process based on the acquired authentication information (S3). Based on whether or not the acquired authentication information is registered in the user information DB 21c, the user authentication unit 26 determines (authenticates) whether or not the user has already been registered as an appropriate user (S4). When the user is not authenticated (S4: NO), that is, when the user is not an appropriate user, the control unit 20 notifies the information processing terminal 3 via the communication unit 22 of an authentication error indicating that the authentication has failed. (S5). In this case, the control unit 20 of the authentication server 2 discards the code pattern information and the authentication information acquired from the information processing terminal 3.

When the user is authenticated (S4: YES), that is, when the user is an appropriate user, the control unit 20 of the authentication server 2 decodes the code pattern information acquired from the information processing terminal 3 (S7), and combines Get machine information. Then, based on the MFP information obtained by decryption and the registration information in the MFP information DB 21b, the MFP management unit (specification unit) 25 specifies the MFP 1 (S8). The control unit 20 of the authentication server 2 determines whether or not the multifunction device management unit 25 has identified the multifunction device 1 (S9). When the MFP 1 cannot be specified (S9: NO), that is, when the acquired MFP information is not registered in the MFP information DB 21b, or when the code pattern cannot be decoded, the control unit 20 Then, a specific error indicating that the identification of the multifunction device 1 has failed is notified to the information processing terminal 3 via the communication unit 22 (S10). In this case, the control unit 20 of the authentication server 2 discards the code pattern information and the authentication information acquired from the information processing terminal 3.
In the information processing terminal 3 notified of the specific error, the control unit 30 displays the specific error on the operation panel 32, for example (S11), and ends the process.

When the MFP 1 can be identified (S9: YES), the control unit 20 of the authentication server 2 uses the print data stored in the electronic data DB 21a in association with the user (user ID) authenticated in step S3. Reading is performed by the storage processing unit 24. Then, the control unit 20 transmits the printing data read from the electronic data DB 21a to the multifunction device 1 identified in step S8 (S12), and instructs the multifunction device 1 to execute the printing process. As a result, it is possible to execute the printing process instructed by the user using the information processing terminal 3.
The destination of the multifunction device 1 is, for example, the authentication server 2 when the destination information (IP address) of the multifunction device 1 is included in the code pattern (multifunction device information) photographed by the image processing unit 33 by the information processing terminal 3. Can be obtained from the code pattern. Further, when the IP address is not included in the code pattern, the authentication server 2 obtains the IP address corresponding to the multifunction machine information (for example, the multifunction machine ID) obtained from the code pattern from the multifunction machine information DB 21b. The destination of the machine 1 can be obtained.

The control unit 10 of the multifunction device 1 acquires print data via the communication unit 14, and the image forming unit 13 outputs an image based on the acquired print data (S13). As a result, the authenticated user can use the multifunction device 1, and the printing process instructed to the multifunction device 1 by the authenticated user is executed.
After the end of image output, the control unit 10 of the multifunction device 1 notifies the processing result to the authentication server 2 from the communication unit 14 (S14). The control unit 20 of the authentication server 2 notified of the processing result notifies the information processing terminal 3 of the processing result by the multifunction machine 1 from the communication unit 22 (S15). The control unit 30 of the information processing terminal 3 displays the notified processing result on, for example, the operation panel 32 (S16), and notifies the user of the information processing terminal 3 of the information. Thereby, the user who has instructed execution of the printing process (image output) by the multifunction device 1 using the information processing terminal 3 can know whether or not the printing process has been properly completed.

As described above, in the image output system according to the first embodiment, when the user requests use authorization (user authentication) of the multifunction device 1 from the authentication server 2 using the information processing terminal 3, the multifunction device 1. There is no need to know the destination information in advance. In addition, since the user can easily acquire the multifunction machine information of the multifunction machine 1 by photographing the code pattern displayed (or pasted) on the multifunction machine 1 by the imaging unit 33 of the information processing terminal 3, the user can easily compose the multifunction machine. Machine 1 can be used. Further, since the multifunction device information is displayed (or pasted) in the form of a code pattern, for example, the network identification information such as the IP address of the multifunction device 1 is prevented from being inadvertently leaked, and security can be maintained.

Also in FIG. 9, the process on the left indicates the process by the multifunction device 1, the process at the center indicates the process by the authentication server 2, and the process on the right indicates the process by the information processing terminal 3.
In the image output system of the second embodiment, the authentication server 2 and the information processing terminal 3 perform the same processes as steps S1 to S11 in the flowchart shown in FIG. If the MFP management unit 25 of the authentication server 2 can identify the MFP 1 based on the MFP information at step S9 (S9: YES), the control unit 20 of the authentication server 2 decrypts at step S7. It is then determined whether or not the MFP information obtained in this way includes encryption information (S21).

  The encryption information is information on an encryption key corresponding to a decryption key used for a decryption process that can be executed by the multifunction device 1, and is included in advance in the multifunction device information. For example, in the image output system, when data is transmitted without being encrypted between the authentication server 2 and the multifunction device 1, or when the security level of communication between the authentication server 2 and the multifunction device 1 is low In addition, the encryption information is included in the MFP information.

  When determining that the encryption information is not included (S21: NO), the control unit 20 of the authentication server 2 performs the same process as step S12 in the flowchart shown in FIG. Thereafter, the multifunction device 1, the authentication server 2, and the information processing terminal 3 perform the same processing as steps S13 to S16 in the flowchart shown in FIG.

  On the other hand, if it is determined that encrypted information is included (S21: YES), the control unit 20 of the authentication server 2 stores the electronic data DB 21a in association with the user (user ID) authenticated in step S3. Print data is read by the storage processing unit 24. Then, the control unit 20 encrypts the read print data using the encryption information included in the MFP information (S22), and transmits the encrypted data to the MFP 1 identified in Step S8 ( S23). As a result, the print data is securely transferred from the authentication server 2 to the multifunction device 1.

  The control unit 10 of the MFP 1 acquires the encrypted data via the communication unit 14, and decrypts the acquired encrypted data using the decryption information (decryption key) held by itself (S24). Based on the printed data, the image forming unit 13 outputs an image (S13). Thereafter, the multifunction machine 1, the authentication server 2, and the information processing terminal 3 perform the same processing as steps S14 to S16 in the flowchart shown in FIG.

  As described above, in the image output system according to the second embodiment, the print data transmitted from the authentication server 2 to the multifunction device 1 is encrypted. Therefore, even if the data being transmitted leaks, It becomes possible to prevent leakage. Further, since the encryption information corresponding to the multifunction device 1 is included in the multifunction device information in advance, the user captures the encrypted information by photographing the code pattern of the multifunction device information with the imaging unit 33 of the information processing terminal 3. Can be obtained.

In the image output systems according to the first and second embodiments, the user stores the print data in advance in the authentication server 2.
Therefore, when actually making an authentication request (printing instruction) to the authentication server 2 using the information processing terminal 3, only the code pattern information and authentication information of the MFP information are transmitted to the authentication server 2. It was a good configuration. Therefore, in the first and second embodiments, it is not necessary to store printing data in the information processing terminal 3, and the amount of data transmitted from the information processing terminal 3 to the authentication server 2 can be reduced.
In addition to such a configuration, when the user makes an authentication request (print instruction) to the authentication server 2 using the information processing terminal 3, the print data is transmitted to the authentication server 2 together with the code pattern information and the authentication information. You may make it do. In this case, since it is not necessary for the authentication server 2 to manage print data for each user, the processing load on the authentication server 2 can be reduced.

  In addition, when the user registers a plurality of print data in the authentication server 2 in advance, the user makes an authentication request to the authentication server 2 using the information processing terminal 3, and when the user is authenticated, the desired print data May be selected. Specifically, when a user who uses the print service accesses the authentication server 2 using the information processing terminal 3 and obtains a predetermined web page, a print request screen as shown on the upper side of FIG. It is displayed on the display unit 32b of the processing terminal 3. FIG. 10 is a schematic diagram showing a modification of the print request screen. In the print request screen shown on the upper side of FIG. 10, as in the print request screen shown in FIG. 7, an input field for entering a user ID and password and a login button are displayed.

  The user operates the operation panel 32 of the information processing terminal 3, inputs his / her user ID and password, and operates the login button. The information processing terminal 3 transmits the user ID and password (authentication information) acquired via the print request screen to the authentication server 2, and the authentication server 2 authenticates the acquired authentication information based on the registration contents of the user information DB 21c. To do. If the authentication is successful, the authentication server 2 transmits a web page for displaying the print request screen shown on the lower side of FIG. 10 to the information processing terminal 3, and the information processing terminal 3, based on the acquired web page, A print request screen as shown in the lower part of FIG. 10 is displayed on the display unit 32b.

  The print request screen shown at the bottom of FIG. 10 is a check for selecting a file name and a registration date and a print target for each of a plurality of print data registered in the authentication server 2 in advance by the logged-in user. Boxes are displayed in association with each other. The check box may be configured so that a plurality of print data can be selected. The print request screen shown at the bottom of FIG. 10 displays an explanation that the pattern displayed on the multifunction device 1 is imaged by the imaging unit 33 of the information processing terminal 3, a shooting button, and a print button. .

  The user operates the operation panel 32 of the information processing terminal 3 to check the check box of the printing data to be printed, and operates the photographing button to photograph the code pattern displayed on the multifunction device 1. After photographing the code pattern, the user operates the print button and requests the authentication server 2 to execute printing by a desired multifunction device 1. Thereby, the user can transmit information indicating the print data to be printed to the authentication server 2 together with the code pattern information. When configured in this manner, operability is improved because data to be printed can be selected from the plurality of print data registered in the authentication server 2 using the information processing terminal 3.

In the first and second embodiments, when the user makes an authentication request (print instruction) to the authentication server 2 using the information processing terminal 3, the code pattern information and the authentication information are simultaneously transmitted from the information processing terminal 3 to the authentication server 2. The configuration was sent. In addition to such a configuration, for example, when only the authentication information is first transmitted from the information processing terminal 3 to the authentication server 2 and the user is authenticated as a result of the authentication processing by the authentication server 2, the authentication is performed from the information processing terminal 3. A configuration in which code pattern information is transmitted to the server 2 may also be used. Further, when the user makes an authentication request, the print data is transmitted to the authentication server 2 together with the code pattern information and the authentication information. The code pattern information is transmitted to the authentication server 2 first, and the authentication server 2 When the MFP 1 can be identified by 2, print data may be transmitted from the information processing terminal 3 to the authentication server 2.

  The information processing terminal 3 according to the first and second embodiments acquires the multifunction machine information by photographing the code pattern by the imaging unit 33, but is not limited to this configuration. For example, when the code pattern of the multifunction device information is a barcode, the information processing terminal 3 includes a code reading unit such as a barcode reader instead of the imaging unit 33, and acquires the multifunction device information by the code reading unit. May be. When the information processing terminal 3 includes an IC card reader, an IC card in which the multifunction machine information is recorded is attached to the multifunction machine 1, and the multifunction machine information is received from the IC card by the IC card reader of the information processing terminal 3. You may make it acquire. Further, when the multifunction device 1 and the information processing terminal 3 are capable of infrared communication using infrared rays, the information processing terminal 3 may acquire the multifunction device information from the multifunction device 1 by infrared communication. .

  In the image output systems of the first and second embodiments, the multifunction device 1 notifies the processing result to the authentication server 2, so that the authentication server 2 can grasp the processing result by the multifunction device 1. Therefore, when notified of completion of the printing process, the authentication server 2 can, for example, delete the print data held in the authentication server 2 and grasp the use status of the multifunction device 1 of each user. In addition, when the processing result includes specific usage status of each user, for example, print processing contents such as output paper size, number of output paper sheets, execution of black and white printing or color printing, based on such information. Thus, billing processing for each user becomes possible.

  The information processing terminal 3 according to the first and second embodiments transmits information (image data) obtained by photographing a code pattern by the imaging unit 33 to the authentication server 2, and the authentication server 2 decodes the code pattern to decode the multifunction device. It was the composition which acquires information. In addition to such a configuration, the information processing terminal 3 has a decoding function, decodes information obtained by photographing a code pattern, acquires multifunction machine information, and acquires the obtained multifunction machine information as the authentication server 2. The structure which transmits to may be sufficient. In this case, the processing burden on the authentication server 2 can be reduced.

  In the information processing terminal 3 according to the first and second embodiments, the user operates the operation panel 32 on the print request screen and inputs authentication information (user ID and password). In addition to such a configuration, for example, when the information processing terminal 3 has an IC card reader, the user ID and password are stored in advance in the IC card, and the authentication information is read from the IC card by the IC card reader. Good.

  The image output system according to the first and second embodiments includes one authentication server 2, and the user accesses the predetermined authentication server 2 and acquires a web page that provides a print service. That is, there is one access-destination authentication server 2. In addition to such a configuration, a plurality of multifunction devices 1 and authentication servers 2 are provided, each managing a plurality of multifunction devices 1 to which each authentication server 2 is assigned in advance, and the user wants to use the multifunction device 1 to be used. It is also possible to access the authentication server 2 that manages the web page and acquire a web page that provides the print service from the authentication server 2.

In this case, for example, the MFP information of the MFP 1 includes server information (authentication device information) for specifying the authentication server 2 that manages the MFP 1, and the information processing terminal 3 acquires the acquired MFP information. Based on the above, the appropriate authentication server 2 is accessed. Specifically, for example, the MFP information of the MFP 1 includes a URL for accessing the authentication server 2 (web page) that manages the MFP 1 that the user wants to use. Then, the information processing terminal 3 that has acquired the MFP information accesses the URL included in the MFP information, thereby accessing the appropriate authentication server 2 and acquiring the appropriate web page (print request screen). That is, the control unit (authentication device specifying unit) 30 of the information processing terminal 3 can specify the authentication server 2 to be accessed based on the URL included in the multifunction machine information. Accordingly, the load of the authentication process can be distributed by the plurality of authentication servers 2 and each user can capture information on the appropriate authentication server 2 (only by photographing the code pattern of the multifunction machine information with the imaging unit 33 of the information processing terminal 3). Destination information).

  The image output systems according to the first and second embodiments are configured such that the authentication server 2 transmits print data to the multifunction device 1 via the network N. Furthermore, as a method for the authentication server 2 to transmit print data to the multifunction device 1, a configuration in which any one of a plurality of communication methods such as FTP communication, HTTP communication, and e-mail transmission can be switched as appropriate may be used. Specifically, the MFP information of the MFP 1 includes a communication method that can be used by the MFP 1, and the authentication server 2 uses the MFP information acquired from the information processing terminal 3. 1 specifies the communication method that can be used, and when the print data is transmitted to the multifunction device 1, the specified method is used. For example, when printing data cannot be transmitted to the multifunction device 1 by FTP communication, the authentication server 2 may transmit the printing data to the multifunction device 1 by e-mail. Note that the email address of the multifunction device 1 may be included in the multifunction device information of the multifunction device 1 or may be registered in advance in the multifunction device information DB 21b of the authentication server 2. As a result, the authentication server 2 can reliably transmit the print data to the multi-function device 1 by an optimum method.

  The above-described configuration is particularly effective when the authentication server 2 is connected to the global network and only the private address is assigned to the multifunction device 1 in the network environment within the company. That is, in such a situation, the authentication server 2 cannot directly communicate with the multi-function device 1, but if the e-mail address of the multi-function device 1 can be acquired, data transmission to the multi-function device 1 is performed using the e-mail address. it can. For example, if the communication method used when the authentication server 2 transmits print data to the multifunction device 1 is fixed (for example, only FTP communication), the method cannot be used by the multifunction device 1 as the transmission destination. The data cannot be transmitted from the authentication server 2 to the multifunction device 1. However, as described above, if any one of a plurality of communication methods can be used, data can be transmitted using an optimal communication method in an environment where the image output system is constructed.

The image output systems according to the first and second embodiments are configured such that the authentication server 2 transmits print data to the multifunction device 1 when the user is authenticated and the multifunction device 1 can be identified. In addition to such a configuration, the authentication server 2 may transmit the corresponding print data to the multifunction device 1 when there is a transmission request from the multifunction device 1. For example, the multifunction device 1 periodically checks the print request with respect to the authentication server 2, and the control unit (request reception unit) 20 of the authentication server 2 receives this confirmation from the multifunction device 1. If there is a print request to the multifunction device 1, the corresponding print data may be transmitted to the multifunction device 1. In this case, even in an environment where data cannot be transmitted from the authentication server 2 to the multifunction device 1, if the multifunction device 1 can access the authentication server 2, the authentication server 2 responds to the request from the multifunction device 1. Accordingly, printing data can be transmitted.
Even if the authentication server 2 fails to transmit print data to the multifunction device 1, the print data can be retransmitted in response to access from the multifunction device 1, so there is no need to interrupt print processing. . In the first and second embodiments, when the authentication server 2 fails to transmit print data to the multifunction device 1, the print data may be retransmitted after a predetermined time has elapsed.

  Furthermore, setting information regarding a print function or a communication function that can be executed by the multifunction device 1 may be included in the multifunction device information of the multifunction device 1. Thus, the user can make settings related to the printing process by the multifunction device 1 only by photographing the code pattern of the multifunction device information with the imaging unit 33 of the information processing terminal 3.

  The image output systems according to the first and second embodiments have a configuration in which a code pattern of MFP information is displayed or pasted on the MFP 1 in advance. In addition to such a configuration, the authentication server 2 may generate a code pattern of multifunction device information based on registration information in the multifunction device information DB 21b. Specifically, since the authentication server 2 manages the MFP information DB 21b, the control unit 20 generates a code pattern using a part of the registration information of the MFP information DB 21b. The control unit 10 of the multifunction machine 1 acquires the code pattern generated by the authentication server 2 by the communication unit 14, displays the acquired code pattern on the display unit 11b, and notifies (presents) the user. In this case, since the authentication server 2 manages information such as the IP address of the multifunction device 1, it is not necessary to include network identification information such as an IP address in the multifunction device information. Therefore, even if the code pattern information transmitted from the information processing terminal 3 to the authentication server 2 is leaked, it is possible to prevent leakage of confidential information such as network identification information.

  Further, the user may instruct the execution of the process in which the authentication server 2 generates the code pattern via the operation panel 11 of the multifunction machine 1. In this case, each time the user instructs the generation of the code pattern, the control unit 10 of the multifunction device 1 requests the authentication server 2 to generate the code pattern, and acquires the generated code pattern. When the authentication server 2 generates the code pattern, the code pattern of each multifunction device 1 can be collectively managed by the authentication server 2 and the multifunction device 1 does not need to have a code pattern generation function. When a code pattern is generated using information that can be changed as appropriate (multifunction peripheral information), the user can request execution of printing processing by the multifunction peripheral 1 using the latest code pattern.

  In the image output system of the present invention, in addition to the multifunction device 1, a printer having only a printer function, a display device for displaying an image, and the like can be used.
