Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In order to more clearly describe the features of the embodiments, a detailed description will be omitted with respect to the matters widely known to those skilled in the art to which the following embodiments belong.

In this specification, the MFP (Multi Function Printer) is used as an example in all embodiments, but it is obvious that various types of image forming apparatuses such as a printer, a scanner, and a copying machine can be used.

Also, in this specification, content refers to all kinds of files that can be printed or displayed, such as documents, images, or images.

1 is a diagram illustrating a secure network system supporting content printing according to an exemplary embodiment of the present invention. Referring to FIG. 1, the secure network system may include a mail server 110, a mobile relay server 120, a printing server 130, and an MFP 20. The mobile terminal 10 can access the secure network system by being connected to the mobile relay server 120 via the Internet.

The mail server 110 manages the transmission and reception of mail through the user account, and in particular, when contents are attached to the mail, the attached contents can be stored in the internal memory.

The mobile relay server 120 relays the mobile terminal 10 so that the mobile terminal 10 can access the mail server 110. That is, when the mobile terminal 10 requests the received mail list, the mobile relay server 120 can acquire the received mail list from the mail server 110 and transmit it to the mobile terminal 10. When the mobile terminal 10 requests the confirmation of the content attached to the received mail, the mobile relay server 120 obtains a preview of the content attached to the received mail in the form of a thumbnail or the like from the mail server 110 To the mobile terminal (10). Accordingly, the user can check the mail list received in his / her mail account and the content attached to the mail in the mobile terminal 10. [

The mobile relay server 120 may request the printing server 130 to print the content stored in the mail server, that is, the content attached to the received mail, at the request of the mobile terminal 10. Upon receiving the print request of the content from the mobile relay server 120, the printing server 130 renders the received content in a printable data format and applies security in a manner such as attaching a watermark, ) And request printing.

In this case, in the process of confirming the contents attached to the received mail through the mobile relay server 120 and requesting the printing, the mobile terminal 10 transmits only a preview of the contents in the form of thumbnails And the original file of the content is not received by the mobile terminal 10. [ That is, the content attached to the received mail is moved only along the mail server 110, the mobile relay server 120, the printing server 130, and the MFP 20 within the security-applied network system, . Therefore, it is possible to enhance the security by preventing the content from being leaked to the outside.

The specific process of printing the content attached to the mail according to the request of the mobile terminal 10 will be described in detail with reference to FIG. 2 to FIG. 6 below.

1, the printing server 130 is constituted by one server. In reality, however, a server for rendering and a server for applying security may be separately provided . In addition, the other servers 110 and 120 may be composed of a plurality of servers that perform detailed functions, and at least two of all the servers 110, 120, and 130 may actually be a single physical server May be integrated and configured.

2 is a diagram illustrating a process of printing contents attached to a received mail in a secure network system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 201, the mobile terminal 10 receives a print request for content from a user. That is, the mobile terminal 10 receives a print request for the content attached to the mail received in the user's account.

A process for the user to confirm the contents attached to the received mail in the mobile terminal 10 and to request printing of the contents will be described in detail as follows.

The mobile terminal 10 requests the mobile relay server 120 to receive the received mail list and the mobile relay server 120 transmits the received mail list to the mail server 10. [ (110) to the mobile terminal (10). The mobile terminal 10 displays the received mail list on the screen. When the user selects any one of the received mail from the list of received mail displayed on the screen of the mobile terminal 10, the contents of the selected received mail are displayed, and if there is the content attached to the received mail, a list of the attached contents is displayed together . At this time, the list of the attached contents is received from the mail server 110 through the mobile relay server 120, like the received mail list.

The user can request printing of the content on the screen of the mobile terminal 10 on which the list of the contents attached to the received mail is displayed. At this time, the user can request confirmation of contents contents from the mobile terminal 10 before requesting the printing. If there is a request, the mobile terminal 10 notifies the contents of the contents stored in the mail server 110 from the mobile relay server 120 A preview can be received in the form of a thumbnail or the like and displayed on the screen. The UI screens displayed on the screen of the mobile terminal 10 in the process of requesting the printing of the contents from the mobile terminal 10 will be described below with reference to FIGS. 3A and 3B.

Returning to FIG. 2, in step 202, the mobile terminal 10 transmits the content ID, user information, and device identification information to the mobile relay server 120.

In this case, the content ID means ID of the content requested to be printed in step 201. [ For example, the content ID may be a file name of the content, or may be various information for identifying the content.

The user information means information about the user of the mobile terminal 10. For example, the user information may be various information that can identify the user, such as a user ID and password for the mail account of the user. Since the user has logged into the account of his / her own account for checking mail in the mobile terminal 10, the mobile terminal 10 transmits information such as the ID and password of the currently logged-in user as user information to the mobile relay server 120 Lt; / RTI >

On the other hand, the device identification information is information for identifying a device to print content. For example, a unique management number may be assigned to the MFP 20 in the secure network system, and such management number may be used as the device identification information. At this time, the management number can be set to correspond to the MAC address of the MFP 20, and the security network system can identify the device to perform printing by checking the MAC address corresponding to the received management number. As another example, the mobile terminal 10 may transmit the MAC address of the MFP 20 itself to the mobile relay server 120 as the device identification information. The MAC address of the device used in the previous operation is stored in the mobile terminal 10, and a list of devices storing the MAC address can be displayed on the screen. If any one of them is selected, the MAC address of the selected device is relayed to the mobile terminal To the server 120.

In step 203, the mobile relay server 120 transmits the content ID received from the mobile terminal 10 to the mail server 110 and requests a content file. In step 204, the mail server 110 transmits a content file corresponding to the content ID received from the mobile relay server 120 to the mobile relay server 120. [

The mobile relay server 120 transmits the content file received from the mail server 110 to the printing server 130 together with the user information and the device identification information received from the mobile terminal 10 in step 205, Lt; / RTI >

In step 206, the printing server 130 generates print data from the received content file, and applies security to the generated print data. Specifically, the printing server 130 generates print data by rendering the received content file and converting it into a printable format. Security can be applied in such a manner that a watermark is attached to the generated print data.

In step 207, the printing server 130 transmits the generated print data to the MFP 20 together with the user information received from the mobile relay server 120. At this time, the printing server 130 may transmit the print data to the MFP 20 using the device identification information received from the mobile relay server 120. [ For example, the printing server 130 may receive the MAC address of the MFP 20 from the mobile relay server 120 and transmit the print data using the received MAC address as a destination.

In step 208, the MFP 20 can print the received print data. At this time, the received user information can be used for user authentication for security. For example, the MFP 20 may request input of a password corresponding to the received user information, or when the user approves the ID card to the MFP 20, the user information stored in the ID card is received through the NFC, And may determine whether the user information received from the server 130 matches the user information.

3A and 3B are views showing UI screens displayed on a screen of a mobile terminal in a process of printing contents attached to a received mail in a secure network system according to an exemplary embodiment.

When "OK" is selected in the third screen 310c, a print request is transmitted to the printer corresponding to the management number "2079". The printer receiving the print request requests user authentication for performing the print job, and the user can perform authentication by NFC tagging the ID card to the printer. Of course, user authentication may be performed in other manners such as inputting a password, or user authentication may be omitted.

Now, referring to FIG. 3B, an example of confirming the preview of the attached content and requesting printing will be described.

Referring to FIG. 3B, the first screen 320a displays a list 321 of contents attached to the mail together with the body of the received mail. When the user selects a content to be checked in the list 321 of the attached content, a preview 322 of the selected content is displayed as in the second screen 320b. At this time, as described above, the mobile terminal receives only the preview of the content from the mobile relay server and displays it on the screen, but does not receive the original file of the content. The user can confirm the contents of the contents through the preview 322 displayed on the second screen 320b.

When the user confirms the preview 322 of the attached content on the second screen 320b and finally selects " print ", the process proceeds to the next step to select the printer on the third screen 320c, The print option can be set in the print setting section 320d. Subsequently, when the user authentication is successful through NFC tagging of the ID card, the printer performs printing. The steps of setting the printer selection and printing options, and performing the user authentication are the same as those described above with reference to FIG. 3A, and therefore, a detailed description thereof will be omitted.

In step 603, the mobile relay server receives content corresponding to the content ID from the mail server. In detail, when the mobile relay server transmits the content ID received in step 602 to the mail server and requests the content, the mail server transmits the stored content file to the mobile relay server in response to the request.

In step 604, the mobile relay server transmits the content file received from the mail server to the printing server together with the user information and the device identification information received from the mobile terminal.

In step 605, the printing server converts the received content file to generate print data, applies security to the generated print data, and transmits the secure print data to the image forming apparatus corresponding to the device identification information.

In step 606, the image forming apparatus prints the received print data.

Meanwhile, according to the embodiment, it is also possible to store the work attached to the mail without printing it immediately after confirming the mail, and to print it later. Hereinafter, the " print later " function will be described with reference to Figs. 7 to 9. Fig.

7 is a UI screen displayed on a mobile terminal for explaining a " print later " function according to an embodiment.

Referring to FIG. 7, in the first screen 700a, the user can select a file to be printed from among the files attached to the mail. On the first screen 700a, an attached file list 701 is displayed, and two of the files ("print function guide.docx" and "UIUX guide.pdf") are selected. When the user selects "OK" after selecting a file to be printed, the second screen 700b is displayed.

The user can select the printer to perform printing on the second screen 700b or can select " print later ". That is, the user can select any of the printers included in the printer list 703 if he wants to print immediately, and can select "print later" 702 if he wants to print later.

When "print later" 702 is selected on the second screen 700b, the selected attached files are stored as a print job, and the name of the print job stored at this time can be set in the third screen 700c. The user can input the name ("training material") of the printing job stored in the input field 705 of the pop-up 704 displayed on the third screen 700c. When the name of the print job is input to the input field 705 and "OK" is selected, a print job of the inputted name is generated, and the generated print job is displayed on the waiting list 706. At this time, the attached files included in the print job are not converted into a printable format, but may be converted into an intermediate format and stored. The user can then invoke the waiting list 706 of stored jobs at any time to request printing.

FIG. 8 is a diagram illustrating a process of performing content printing when executing the " print later " function according to an embodiment.

8, if the user selects " print later " for the content attached to the mail in the mobile terminal 10 in step 801, the mobile terminal 10 transmits the content ID and the user information to the mobile To the server 120. Here, the content ID is information for identifying the content such as a file name of the content, and the user information is information for identifying the user of the mobile terminal 10. [ For a detailed description of the content ID and user information, refer to the description of step 202 in FIG.

In step 803, the mobile relay server 120 transmits the content ID received from the mobile terminal 10 to the mail server 110 and requests a content file. In step 804, the mail server 110 transmits the content file corresponding to the content ID received from the mobile relay server 120 to the mobile relay server 120.

In step 805, the mobile relay server 120 transmits the content file received from the mail server 110 to the printing server 130 together with the user information received from the mobile terminal 10. [

In step 806, the printing server 130 converts the received content file into an intermediate format, and stores the converted content file as a print job. In this case, the intermediate format means a format that goes through the middle in the process of converting the content file into the printable format. In other words, the content file is converted and converted into an intermediate format, and the converted data is further converted in the intermediate format to generate print data. On the other hand, the print job can be stored together with the received user information.

After the print job is stored, the user can then request a print by calling up a list of print jobs stored in the mobile terminal 10 at a desired point in time. In step 807, when the mobile terminal 10 receives the print request for the stored print job from the user, it transmits the print job identification information and the device identification information to the mobile relay server 120 in step 808. [ In this case, the device identification information is information for identifying a device to print content, and the print job identification information is information for identifying a print job selected in step 807. [

In step 809, the mobile relay server 120 transmits the print job identification information and the device identification information to the printing server 130, and requests printing of the content.

In step 810, the printing server 130 retrieves the print job corresponding to the received print job identification information, converts the content of the intermediate format included in the print job, generates print data, and applies security.

In step 811, the printing server 130 transmits the generated print data and user information to the MFP 20 corresponding to the device identification information. At this time, the user information can be extracted from the stored print job.

In step 812, the MFP 20 prints the received print data. At this time, user authentication may be performed to enhance security.

30 is a flowchart illustrating a method of printing or displaying contents by designating an output apparatus as a mail subject according to an embodiment.

Referring to FIG. 30, in step 3001, the user inputs a print representative e-mail address at a receiving address, inputs a management number given to an output device in a mail subject, and requests the transmission of a mail by attaching contents to the mail.

In step 3002, the mail server transmits the content attached to the mail to the printing server when receiving the mail attached to the content, which has the print representative e-mail address as the destination address. At this time, the mail server may transmit the mail title together with the printing server, or may identify the output device corresponding to the mail title and provide identification information (e.g., an IP address or a MAC address) of the verified output device to the printing server .

In step 3003, the printing server renders the received content and transmits the rendered content to an output device corresponding to the mail title. At this time, the printing server performs content rendering according to the type of the output device. That is, if the output device identified by the mail subject is a display device, the printing server converts the content into a displayable format. Alternatively, if the output device identified by the mail title is a printing device such as a printer, the printing server converts the content into a printable format. On the other hand, the determination of the output device corresponding to the mail title can be performed by either the printing server or the mail server.

In step 3004, the output device receiving the content outputs the content according to the type of the output device. That is, if the output device is a display device, the received content is displayed on the screen, and if the output device is a printing device, the received content is printed on the print medium.

An embodiment in which the output device is designated as the mail subject to output the content attached to the mail and the use of the release code is used for security enhancement will be described with reference to FIGS. 31 to 33. FIG. In the embodiment described below, there is an advantage that security can be enhanced by outputting the content only when the release code transmitted through reply mail is input to the output device.

31 is a diagram for explaining a method for designating an output apparatus as a mail title and outputting a content using a release code included in a reply mail according to an embodiment.

31, a display number (" 3402 ") is displayed on the screen of the display device 3120 connected to the PC 3110 and the PC 3110. [ At this time, the display application is executed in the PC 3110, so that the PC 3110 functions as an output device of the content, and the content can be displayed on the display device 3120 connected to the PC 3110. In addition, the display number means a control number assigned to the output device of the content, and in this case, the control number assigned to the PC 3110.

The user runs the email app on the mobile terminal or PC, inputs the print representative email address (" cloudprint@samsung.com ") to the destination address on the first screen 3100a for email transmission, And sends the attached mail. At this time, the display number (3402) confirmed by the display device 3120 connected to the PC 3110 or the PC 3110 is inputted in the title.

When the user transmits the mail as described above, the reply mail including the release code necessary for outputting the content is transmitted to the user. A reply message including a release code (" 241251 ") is displayed on the second screen 3100b. The second screen 3100b is displayed with a release code ("241251") and a message prompting the user to input a release code to the output device corresponding to the display number entered as the mail title.

When the user inputs the release code ("241251") confirmed in the reply mail to the PC 3110, the content (document 1) attached to the mail is displayed on the display device 3120 connected to the PC 3110. At this time, the operation of rendering the contents attached to the mail in a displayable format can be performed by the mail server or by a separate rendering server connected to the mail server.
