The location acquisition unit 100 acquires the installation location information 400 from the authenticated image forming apparatus 2.

The location acquisition unit 100 acquires the installation location information 400 including the physical address of the connected authenticated image forming apparatus 2 and stores it in the storage unit 19. At this time, the location acquisition unit 100 may associate the installation location information 400 with the identification information of the image forming apparatus 2 and store so as to add a record to the database.

Further, the location acquisition unit 100 may periodically acquire the installation location information 400 for all the authenticated image forming apparatus 2 and store it in the database.

As described above, the physical address acquisition process according to the embodiment of the present disclosure is completed.

[Authenticated Apparatus Search Process by Image Forming System X]

Next, with reference to FIG. 7, the authenticated apparatus search process by the server 1 and the terminal 3 according to the embodiment of the present disclosure is described.

In this authenticated apparatus search process, the server 1 searches for the authenticated image forming apparatus 2 near the terminal 3 according to the user's instruction from the terminal 3. The terminal 3 receives the search result information from the server 1 and presents it to the user.

In the authenticated apparatus search process of the present embodiment, the control unit 10 of the server 1 mainly executes the control program stored in the storage unit 19, and the control unit 30 of the terminal 3 executes the control program stored in the storage unit 39 in cooperation with each unit and by using the hardware resources.

Hereinafter, with reference to the flowchart of FIG. 7, the details of the authenticated apparatus search process according to the present embodiment is described step by step.

(Step S311)

Firstly, the position acquisition unit 38 of the terminal 3 performs the position acquisition process.

The user searches for the authenticated image forming apparatus 2 and activates a dedicated application for instructing printing of the confidential document 420.

Then, the position acquisition unit 38 acquires the position information 430 by receiving the radio wave from the GNSS, or the like, or calculating the positional relationship among the base stations.

(Step S312)

Next, the information transmission unit 300 performs the authentication input position transmission process.

When the dedicated application is started, the information transmission unit 300 causes the display unit 37 to display a dialog box, or the like, requesting the input of the authentication information 440.

As a result, the user inputs the authentication information 440 via the input unit 36.

The information transmission unit 300 transmits the position information 430 acquired by the position acquisition unit 38 and the authentication information 440 inputted by the input unit 36 to the server 1.

At this time, although the information transmission unit 300 connects to the public network 5a, it can connect to the server 1 in the private network 5b whose connection is restricted via the firewall 6. In this case, for example, the information transmission unit 300 can connect to the server 1 by using the IPV6 address set in the dedicated application or performing address resolution by using a special protocol.

When the connection is established, the terminal 3 transmits the authentication information 440 to the server 1. At this time, the terminal 3 may access the server 1 while encrypting with the above-mentioned special authentication code.

(Step S111)

Here, the information acquisition unit 110 of the server 1 performs the information acquisition process.

The information acquisition unit 110 acquires the position information 430 and the authentication information 440 by accessing from the dedicated application of the terminal 3 via the public network 5a and the private network 5b. The information acquisition unit 110 temporarily stores the acquired position information 430 and authentication information 440 in the storage unit 19.

(Step S112)

Then, the authentication unit 120 performs the authentication process.

The authentication unit 120 authenticates with the authentication information 440 acquired by the information acquisition unit 110. Specifically, the authentication unit 120 refers to the account setting 410 and authenticates the user with the authentication information 440.

The authentication unit 120 authenticates with the username, password, authentication code, or the like, included in the authentication information 440. Further, the authentication unit 120 may authenticate whether or not the acquired position information 430 is included in the travel destination information. That is, the authentication unit 120 may authenticate whether or not the user is at the travel destination.

(Step S113)

Next, the authentication unit 120 determines whether or not the authentication is successful. The authentication unit 120 determines Yes if the authentication is successful in the above-mentioned authentication process. The authentication unit 120 determines No if authentication fails, or the like. Here, the authentication unit 120 may determine No if the user's position information 430 is not included in the travel destination information.

In the case of Yes, the authentication unit 120 approves the terminal 3 to access the server 1. As a result, the connection between the dedicated application of the terminal 3 and the server 1 is established. After that, the authentication unit 120 proceeds to the process in step S114.

In the case of No, the authentication unit 120 ends the authenticated apparatus search process and disconnects from the terminal 3.

(Step S114)

If the authentication is successful, the location search unit 130 of the server 1 performs the location search transmission process.

Here, the user requests the search of the authenticated image forming apparatus 2 by using the dedicated application of the terminal 3.

Then, the location search unit 130 acquires the request from the dedicated application of the terminal 3.

As a result, the location search unit 130 searches for the authenticated image forming apparatus 2 that is close to the user's position information 430.

Specifically, first, the location search unit 130 calculates a physical address such as a postal address from the position information 430 acquired from the terminal 3. The location search unit 130 can calculate the postal address, or the like, by using the map data stored in the storage unit 19, the map service on the cloud, or the like.

In the present embodiment, for example, the location search unit 130 calculates the zip code from the position information 430. On this basis, the location search unit 130 searches for the installation location information 400 included the calculated zip code with reference to the storage unit 19. Specifically, the location search unit 130 searches for the physical addresses of all the authenticated image forming apparatuses 2 in the calculated zip code. That is, the location search unit 130 searches for the physical addresses of all authenticated image forming apparatus 2 including the calculated zip code from the database of the storage unit 19.

At this time, if the acquired position information 430 is within the specific range from the boundary of the zip code, the location search unit 130 can also search the installation location information 400 corresponding to the zip code beyond the boundary.

On this basis, the location search unit 130 transmits the searched installation location information 400 to the dedicated application of the terminal 3.

Further, the location search unit 130 may calculate the position corresponding to the position information 430 from the installation location information 400 and transmit this position to the terminal 3.

Alternatively, the location search unit 130 may directly acquire the zip code corresponding to the position information 430 or the zip code inputted by the user by using the input unit 36 from the terminal 3. In this case as well, the location search unit 130 may search for the physical addresses of all the authenticated image forming apparatuses 2 in the zip code and transmit the searched information to the terminal 3.

In addition, if the physical address of the authenticated image forming apparatus 2 is not included in the acquired zip code of the location information 430 and the zip code beyond the boundary, the location search unit 130 tells that there is no physical address to the terminal 3.

(Step S313)

If the authentication is successful, the location presentation unit 310 performs the location reception process.

The location presentation unit 310 receives the installation location information 400 indicating the installation location of the authenticated image forming apparatus 2, which is close to the position information 430, from the server 1.

Specifically, the location presentation unit 310 waits for a response from the server 1 after transmitting the above-mentioned request.

Then, when the installation location information 400 is acquired, the location presentation unit 310 temporarily stores it in the storage unit 39. This makes it possible to acquire the physical address of the authenticated image forming apparatus 2 in the current zip code.

Here, if there is no response from the server 1, the location presentation unit 310 retransmits the request and waits for the reception of the installation location information 400. At this time, if the re-transmission exceeds the set maximum allowable number of times, the location presenting unit 310 stops the transmission of the request as an error such as a timeout, or the like.

(Step S314)

Next, the location presentation unit 310 of the terminal 3 determines whether or not the location reception is successful.

If the location presentation unit 310 acquires the installation location information 400, it determines Yes. In other cases, for example, if the location presentation unit 310 obtains the above-mentioned response to the effect that the search is not performed or an error occurs, the location presentation unit 310 determines No.

In the case of Yes, the location presentation unit 310 advances the process to step S315.

In the case of No, the location presentation unit 310 ends the authenticated apparatus search process.

(Step S315)

Here, the location presentation unit 310 performs the location presentation process.

The location presentation unit 310 displays the installation location information 400 in order of closeness from the position information 430.

Specifically, the location transmission unit 200 compares the received physical address of the authenticated image forming apparatus 2 with the current position information 430. Then, the place transmission unit 200 arranges the authenticated image forming apparatuses 2 nearby in the order of distance from the closest side, and it displays them on the display unit 37.

In addition, if the location presentation unit 310 receives a response that the search is not performed, the location presentation unit 310 may display a display such as “a printer cannot be found nearby” on the display unit 37. On the other hand, the location presentation unit 310 may display the content of the error on the display unit 37 even in the case of an error.

As described above, the authenticated apparatus search process according to the embodiment of the present disclosure is completed.

[Confidential Document Printing Process by Image Formation System X]

Next, with reference to FIG. 8, the confidential document printing process by the image forming system X according to the embodiment of the present disclosure is described.

In this confidential document printing process, a print job is transmitted from the server 1 and printed out according to an instruction from the terminal 3 authenticated by the server 1.

In the confidential document printing process of the present embodiment, the control unit 10 of the server 1 mainly executes the control program stored in the storage unit 19, and the control unit 20 of the image forming apparatus 2 executes the control program stored in the storage unit 29, the control unit 30 of the terminal 3 executes the control program stored in the storage unit 39, in cooperation with each unit by using the hardware resources.

Hereinafter, with reference to the flowchart of FIG. 8, the details of the confidential document printing process according to the present embodiment is described step by step.

(Step S120)

Firstly, the location search unit 130 of the server 1 performs an instruction acquisition process.

Here, the dedicated application of the terminal 3 can access the confidential document 420 stored in the server 1, which is secured and protected, after the authentication. That is, the user can browse the list of printable confidential documents 420 and instruct printing from the dedicated application.

Upon acquiring the print instruction from the user's input unit 36, the location presentation unit 310 of the terminal 3 transmits this to the server 1.

The location search unit 130 of the server 1 acquires the printing instruction.

(Step S121)

Here, in the case of the authenticated terminal 3, the location search unit 130 of the server 1 performs the confidential document transmission permission process.

The location search unit 130 transmits a print job to the authenticated image forming apparatus 2 closest to the position information 430 of the terminal 3. Specifically, the location search unit 130 sets the confidential document 420 in a state where this image forming apparatus 2 can acquire the confidential document 420 as the print job, and it notifies to this image forming apparatus 2 of the state. As a result, the image forming apparatus 2 can acquire the confidential document 420 by a security-conscious protocol such as HTTPs or SFTP (SSH File Transfer Protocol).

(Step S221)

Here, the confidential document acquisition unit 210 of the image forming apparatus 2 performs the confidential document acquisition process.

The confidential document acquisition unit 210 acquires the confidential document 420 from the server 1 as a print job and temporarily stores it in the storage unit 29. The confidential document acquisition unit 210 may acquire the confidential document 420 by using a security-conscious protocol. Further, the confidential document 420 may be encrypted with the special authentication code. This makes it possible to prevent an outsider from printing or viewing the confidential document 420.

(Step S222)

Then, the confidential document acquisition unit 210 of the image forming apparatus 2 to which the print job is transmitted determines whether or not the authenticated terminal 3 is nearby.

If the confidential document acquisition unit 210 confirms that the terminal 3 is certainly on the side of the image forming apparatus 2, it determines Yes. Therefore, the confidential document acquisition unit 210 may communicate with the dedicated application of the terminal 3 via the server 1 or by WiFi-direct, or the like, to confirm that the terminal 3 is authenticated. Further, the confidential document acquisition unit 210 may acquire the position information 430 again at the time of this communication and confirm that it is near the installation location information 400 stored in the storage unit 19. Further, the confidential document acquisition unit 210 may confirm the user itself by logging in to the user of the terminal 3, inputting a PIN or a one-time password, or performing biometric authentication, from the operation panel unit 26.

Based on these confirmations, the confidential document acquisition unit 210 determines No if the terminal 3 is not on the side of the image forming apparatus 2.

In the case of Yes, the confidential document acquisition unit 210 advances the process to step S223.

In the case of No, the confidential document acquisition unit 210 ends the confidential document printing process and discards the confidential document 420. Then, the confidential document acquisition unit 210 transmits the determination result to the server 1.

(Step S223)

Then, the confidential document acquisition unit 210 and the image forming unit 27 perform the image forming process.

The confidential document acquisition unit 210 causes the image forming unit 27 to form an image of the acquired confidential document 420. At this time, the confidential document acquisition unit 210 can decrypt the confidential document 420 with the authentication code for each page, discard the decrypted data after printing, or add a watermark to the printed matter. Further, the confidential document acquisition unit 210 may delete the confidential document 420 after the print output.

As described above, the confidential document printing process according to the embodiment of the present disclosure is completed.

As configured in this way, the following effects can be obtained.

In a typical technology, a method of identifying a printing apparatus and performing printing is disclosed. This method used a wireless beacon such as Bluetooth® that needs to be installed and activated in the image forming apparatus 2.

Therefore, the printing apparatus could be specified only in the range where the wireless beacon can be received, for example, inside a building.

On the other hand, the image forming system X according to the embodiment of the present disclosure is an image forming system including a terminal 3, a server 1, and a plurality of image forming apparatuses 2. The terminal 3 includes a position acquisition unit 38 that acquires position information 430, an input unit 36 that inputs authentication information 440, an information transmission unit 300 that transmits the position information 430 acquired by the position acquisition unit 38 and the authentication information 440 input by the input unit 36 to the server 1, a location presentation unit 310 that receives and presents the installation location information 400 indicating the installation location of the image forming apparatus 2 close to the position information 430 from the server 1. The server 1 includes a location acquisition unit 100 that acquires installation location information 400 from each of the plurality of image forming apparatuses 2, a storage unit 19 that stores installation location information 400 acquired by the location acquisition unit 100 and a confidential documents 420, an information acquisition unit 110 that acquires the position information 430 and the authentication information 440 from the terminal 3, authentication unit 120 that authenticates with authentication information 440 acquired by information acquisition unit 110, and a location search unit 130 that searches for the installation location information 400 stored in the storage unit 19 and transmits the installation location 400 to the terminal 3 based on the position information 430 when authenticated by the authentication unit 120. Each of the plurality of image forming apparatuses 2 includes a location transmitting unit 200 that transmits the installation location information 400 to the server 1, a confidential document acquisition unit 210 that acquires the confidential document 420 in response to an instruction from the terminal 3 authenticated by the server 1, and an image forming unit 27 that forms an image of the confidential document 420.

With such a configuration, it is not necessary to provide a wireless beacon, and it is possible to provide an image forming system that can search and identify an image forming apparatus beyond the range of the wireless beacon. As a result, a user such as a traveler can search for the authenticated image forming apparatus 2. Then, the confidential document 420 stored in the server 1 in consideration of security can be printed by the searched image forming apparatus 2. Therefore, users belonging to the military, government, a hospital, a company, a partner, or the like, can safely and easily print the confidential document 420 even at travel destination.

In the image forming system X according to the embodiment of the present disclosure, the installation location information 400 includes a zip code, and the location search unit 130 calculates the zip code from the position information 430 and presents the installation location information 400 in the zip code to the terminal 3.

With this configuration, the image forming apparatus 2 that is near the terminal 3 and is reachable can easily be searched by using the zip code. Therefore, the convenience of the user can be improved.

In the image forming system X according to the embodiment of the present disclosure, the location presentation unit 310 displays the installation location information 400 in order of closest from the position information 430.

With this configuration, even if the installation location is searched by zip code, the authenticated image forming apparatus 2 can be presented in the order of closeness. As a result, the user can access the closest image forming apparatus 2 except for the distant image forming apparatus 2 regardless of the zip code. Therefore, the convenience of the user can further be improved.

In the image forming system X according to the embodiment of the present disclosure, the location search unit 130, when the position information 430 is within a specific range from the boundary of the zip code, also presents the installation location information 400 corresponding to the zip code beyond the boundary to the terminal 3.

With this configuration, it is possible to search for and present the authenticated image forming apparatus 2, which locates to the boundary of the county, or the like, and has the different zip code but close to. Therefore, the user can print the confidential document 420 even at a zip code different from the zip code at the current position, which can improve convenience.

In the image forming system X according to the embodiment of the present disclosure, the location search unit 130 calculates a position corresponding to the position information 430 from the installation location information 400 and transmits the position to the terminal 3.

With this configuration, it is possible to display the installation location information 400 on a map of a dedicated application, for example, instead of simply indicating the installation location information 400 by an address. Thereby, the convenience can be further enhanced.

Other Embodiments

In the above-described embodiment, an example in which the confidential document 420 is already stored in the server 1 has been described.

However, the terminal 3 may include a document transmission unit that transmits the confidential document 420 to the server. Here, the document transmission unit may be able to transmit the confidential document 420 to the server 1 when “print” or “send” is selected by the user on the dedicated application of the terminal 3. In this case, the document transmission unit converts electronic document data such as PDF and files of various applications, or the like, stored in the terminal 3 into print job data such as PDL and the like, and sends the data to the server 1. In this case as well, the document transmission unit may set a special authentication code, one-time password, or PIN and add it to the data of this print job. Alternatively, the document transmission unit may be configured to acquire the confidential document 420 from another server of the organization to which the user belongs, a server on the cloud, and directly transmit it to the server 1. Alternatively, the document transmission unit may set the necessary confidential document 420 in accordance with the user inputting the travel destination information, and it acquire and store the necessary confidential document 420 according to the user's instruction.

With such a configuration, the convenience of the user is enhanced, and the necessary confidential document 420 can be easily printed by the authenticated image forming apparatus 2.

Further, in the above-described embodiment, an example in which the confidential document 420 is acquired from the server 1 and printed is described.

However, with the scanner of the searched authenticated image forming apparatus 2, or the like, a document that is a printed matter owned by the user can be scanned, uploaded this as a confidential document 420 to the server 1, and stored it. In this case, uploading may be possible only from the closest image forming apparatus 2 searched in accordance with the user authentication by the dedicated application of the terminal 3 of the above-described embodiment.

With this configuration, the confidential document 420 can be stored as well as printed. Furthermore, it may be possible to share this stored confidential document 420 with other users. As a result, the convenience of the user can be improved.

In the above-described embodiment, an example in which the system administrator sets the installation location information 400 when the image forming apparatus 2 is installed has been described.

However, each image forming apparatus 2 may be provided with a functional block similar to the position acquisition unit 38 of the terminal 3, such as a GNSS receiver, a communication unit for mobile network, or the like. As a result, each image forming apparatus 2 may directly acquire similar position information as the position information 430 and set the installation location information 400 based on the acquired position information. Further, the installation location information 400 acquired in this way may also be transmitted to the server 1 and compared with the information of the physical address, which has already been acquired. In this case, if they do not match, the authentication may be revoked as an error.

Further, for example, based on the acquired position information, each image forming apparatus 2 may include position information in units of several meters even inside the building into the installation location information 400. On this basis, the position information 430 of the terminal 3 may be compared with the position information included in the installation location information 400 of the authenticated image forming apparatus 2.

With such a configuration, the user can easily access the authenticated image forming apparatus 2. Therefore, the convenience can be further enhanced.

Further, in the above-described embodiment, basically, it is described that the installation location information 400 is searched by the zip code.

However, as described above, the server 1 may acquire the position information based on the GNSS or the mobile network similar to the position acquisition unit 38 of the terminal 3 and store it as the installation location information 400. On this basis, it is also possible to search the position information 430 transmitted from the terminal 3 and the position information of the installation location information 400 to search each image forming apparatus 2 without using the zip code.

In this case, the server 1 can search the position information 430 for the position information stored in the installation location information 400, and it can directly transmit the position information to the terminal 3. Here, when the server 1 stores the installation location information 400 including the physical address as the postal address, it may be possible to convert this into location information. On the terminal 3, these can be displayed as it is on the map as the position of the authenticated image forming apparatus 2.

As a result, the user can more easily grasp the position of the authenticated image forming apparatus 2, and the convenience can be enhanced.

In the above-described embodiment, an example of searching the installation location information 400 of the authenticated image forming apparatus 2 by a zip code has been described.

However, although the search is usually performed by using the zip code, depending on a condition, the search may be performed by using the information on the position of the physical address of the authenticated image forming apparatus 2. The condition may include the case where the user is at the border of the zip code, that is, the border of the county or state, or the like. In this case, the area of the same zip code on the map may be set by the coordinates of the polygons, and the distance from the edge of each polygon is calculated from the user's position information 430. Then, if this distance is closer than the specific distance, it may be determined to be at the border. In addition, this specific distance can be set as the above-mentioned specific range.

With this configuration, the user can search for a closer and more suitable authenticated image forming apparatus 2 when the user is at the boundary position between the zip codes. Therefore, the convenience of the user can be further enhanced.

In addition, in such a case, the search may be performed in consideration of the situation such as whether the user is moving by car, walking or biking, and the route of them.

In the above-described embodiment, it is described that the confidential document 420 can be printed only if the terminal 3 is near the image forming apparatus 2 to which the installation location information 400 is transmitted.

However, if there is a dedicated staff member who stores the printed matter of the confidential document 420 when it is printed, or the like, the location search unit 130 of the server 1 may be instructed the staff to store the printed matter by e-mail, chat, SMS, or the like. Whether or not there is the staff, or the like, in this way may be set in the installation location information 400.

With this configuration, both security and user convenience can be achieved.

In the above-described embodiment, the location acquisition unit 100 of the server 1 is described so as to authenticate and acquire the installation location information 400 when the image forming apparatus 2 is installed.

However, the location acquisition unit 100 may search the image forming apparatus 2 in the public network 5a and the private network 5b to acquire the installation location information 400. Alternatively, the location acquisition unit 100 may determine the status of each image forming apparatus 2 and perform authentication according to service information such as billing.

Further, the present disclosure can be applied to an information processing apparatus other than the image forming apparatus. That is, a network scanner, a server 1 in which the scanner is separately connected by USB, or the like, may be used.

Further, it goes without saying that the configuration and operation of the above-described embodiment are examples, and it can be appropriately modified and executed without departing from the aim of the present disclosure.
