The service server 310 stores user information such as a user ID, a password, or terminal information for the user authentication.

The user terminal 340 requests access authentication to the service server 310 using a communication program installed therein. The service server 310 permits the user access using the terminal information or the user information transmitted by the user terminal 340 and transmits the permission information to the print server 330 so that the user terminal 340 prints. When the server 330 is connected, the print server 330 allows the access of the corresponding user terminal 340 by using the permission information. In this case, the terminal may be authenticated by using unique information of the user terminal as terminal information for authentication or by using a phone number of the user in the case of a mobile phone.

After the user authentication and access are allowed, the user terminal 340 transmits the file of the user terminal to the connected print server 330 by using the built-in communication program so that the corresponding print server 330 outputs or The print server 330 may be transmitted to the remote place through P2P communication for printing.

As described above, the cloud printing system according to the present invention can be remotely transmitted and printed through communication between a transmitter and a receiver, for example, as follows. If Hong Kil-dong is out of office at Gangnam Station and needs to print out the suddenly left sales strategy report, request the report by text from the outside team leader. Since the team leader is storing the sales strategy report on the smartphone, he accesses the cloud printing system and transmits the corresponding file. Hong Gil-dong will be able to print and print out the file by connecting to a print server installed in a nearby convenience store.

In this case, the user terminal 340 of the receiver also downloads and installs a communication program in the same manner as the sender, and the same user authentication method may be used. In addition, the print server 330 may be provided with the same dedicated software as the other print server 330.

The file transfer and output procedure using the cloud printing system will be described in more detail as follows. Cloud printing system using a mobile terminal according to an embodiment of the present invention is connected to the service server 310 or the print server 330 to install the communication program installed in the user terminal 340 and installed. Then, when the user requests authentication to the print server 330 using the communication program, the print server 330 recognizes the accessor and transmits the corresponding user information or terminal information to the service server 310 to request permission. . After confirming the user in the service server 310 and allowing the connection to the print server 330, the user connection procedure is completed and the corresponding print server 30, 31 can be freely transmitted or received within the permitted range. Can be used.

As such, the cloud printing system using the portable terminal improves user convenience by allowing the mobile terminal to conveniently print at any time and place by connecting to various printing environments and outputting the contents.

In addition, according to another embodiment of the present invention, the user terminal 340 accesses a specific print server 330 and transmits an output target file to a print server 330 in which another user is located at the request of another user terminal 340. The transmission information is transmitted to the service server 310. Alternatively, at the request of the other user terminal 340, the user may set an authority so that another user can use the output target file previously uploaded according to his or her needs. When the user who wants to output the file is connected to the print server 330 of the nearest location, a list of target files that the user can use is displayed on the screen of the user terminal 340, and the user wants to output the file among the displayed files. Select the file to request output.

In this case, the print server 330 transmits an output request to the service server 310. The service server 310 requests the transmission of the file to the print server 330 that physically stores the file requested by the user, and the print server 330 transmits the output target file to the request print server 330. . Alternatively, the user terminal 340 designates a receiver in advance and transmits the file to the print server 330 when the user terminal 340 transmits the file, and the service server 310 determines which print server 330 the receiver is connected to. The output target file may be transmitted to the request print server 330. When the request print server 330 receives the output target file, the request print server 330 converts the original print output information for output, calculates the number of output pages, and requests the user terminal 340 for mobile payment.

Although not shown, when the request print server 310 receives a file, the request print server 310 may further include a procedure of notifying the request user terminal 340 of the file, such as by receiving an SMS. It can be a server. When the user pays the fee at the mobile terminal and the payment completion code is sent to the service server 310 by the communication company server or the mobile payment server, the request print server 330 prints an output target file waiting to be output to the print 331. Send and print. In this case, the billing process and the payment procedure in the mobile terminal in the request print server 330 may be omitted or modified. In addition, the output target file may be deleted immediately after output for security reasons or after a predetermined period of time.

Meanwhile, when the output target file is transmitted to the print server, the output target file may be encrypted to maintain security on the wired / wireless network. The output destination file may exist in various formats, and may be a file stored in a user's mobile terminal or may exist in a specific physical location of a print server or a remote device depending on the storage location. As such, the cloud printing system according to an embodiment of the present invention generates and converts a file to be output to a printer as raw print output information in order to identify the corresponding file according to the location and format of various files, and to control access and conversion of the output. Has the function to That is, the cloud printing system according to the embodiment of the present invention can prevent the file leakage by converting the output target file into the raw print output information and outputting the output to the receiver of the file.

In addition, the screen interface of the communication program of the portable terminal enables file classification according to a user's purpose regardless of the physical location of the file. That is, by enabling file classification according to a search or classification according to a region regardless of the physical location of the file, the user has an effect of sharing the resources of the print server of the entire cloud printing system. Therefore, the user can easily manage the identification and access management of the output file.

The payment method according to the output of the output target file may be processed by linking an advertisement for free, in connection with a mobile terminal payment system, or in connection with an electronic wallet that can be linked to a mobile terminal. In this case, a payment server for payment may be separately configured or a function of the service provider server may be performed. The print server calculates the output cost by counting the number of output pages of the output target file, requests the mobile payment by the user terminal, and the payment completion code is transmitted by the service provider server or the mobile payment server after the user makes a payment. Sending to the server allows the print server to send files to the print queue.

Meanwhile, according to another embodiment of the present invention, the request print server 330 searches for the print servers 330 around it and transmits the corresponding file according to a predetermined rule without passing the request information and reception through the service server 310. do. Alternatively, the print server 330 receiving the file may be directly transmitted to the print server 330 designated by the user.

That is, the user terminal 340 accesses a specific print server 330 and transmits an output target file to the print server 330 when a request of another user is made. Or, at the request of another user, set the authority so that other users can use the output target file uploaded according to their needs. When a user who wants to print the file is connected to a nearby print server 330, a list of target files that the user can use is displayed on the screen of the user's mobile terminal, and the user selects a file to output from the displayed files. Request output.

In this case, the print server 330 receiving the output request searches for the print server 330 physically storing the file requested by the user and requests the transmission of the corresponding file, and the print server 330 requests the print server ( In step 330, the output target file is transmitted. Alternatively, when the user terminal 340 designates and transmits a recipient in advance when the file is transmitted, the print server 330 determines which print server 330 the recipient is connected to and directly outputs the request to the print server 330. You can also transfer the target file.

Thus, by configuring a printing system using a single server to use a plurality of print servers, the print servers can share the outputs through peer-to-peer communication with each other, thereby preventing a service failure due to an increase in the load of the service server.

That is, when the cloud printing procedure using the mobile terminal according to the above-described embodiment of the present invention is described, a print server connection step in which a user connects to a print server and a file transmission in which a sender transmits an output target file requested by a receiver to a print server A file conversion step of converting the output target file into raw print output information so as to be applicable to various environments, a billing step of performing payment according to the corresponding output, and outputting the actual output from the printer connected to the print server after payment Steps. The printer connection step may be configured to request user authentication from a user terminal to a service server to access a print server, or directly connect to a print server to check the user authentication with a service server.

The file transfer step may be configured to perform the request of the user who requested the output target file and the existence of the file on the service server, or directly on the print server. The charging step may be omitted, and the file conversion step may expand the versatility since the file may be converted into raw print output information to be output regardless of the printer type so as to correspond to various output requests and various output environments of the user.

Further, after performing a security audit on the document in the user terminal according to a security policy set in the service server, a security certification mark is attached to a document that has passed the security audit and transmitted to the remote terminal for output.

The service server pre-stores a security policy necessary for the security audit, and pre-stores a policy of content classification of a permission level document of a document set by the application program. It also has functions such as blocking output of documents, notifying administrators, backing up information, and generating document logs.

In a typical application, the printer output process is as follows. An application requests a document output, and the application calls GDI to output the document and converts the document into a printer format. At this time, the Windows operating system converts it to WMF (window meta file) or EMF (Windows Enhanced Meta File), and other operating systems such as Linux or Unix to printer spool file. Sending the converted spooling file to a print driver causes the print driver to send the spooling file to a printer for output.

However, in the document authentication and output method according to an embodiment of the present invention, when a specific output document is transmitted to a remote place in an application program of a user terminal, a printer installed in the user terminal in the application program to send to a remote terminal to be transmitted. Call the virtual driver. The printer virtual driver converts the corresponding output document into the printer spool file and the like, and converts the output document into a file format compatible with any terminal and transmits the converted document file to an application program of the user terminal. The application program transmits to the remote terminal to be transmitted. The application program of the remote terminal enables to output the received document file through a printer connected to the remote terminal.

The language processing procedure may include a preprocessing step of extracting text from a document, a morpheme analysis step of analyzing a morpheme from the extracted text, a syntax analysis step of analyzing a syntax from the morpheme, a key word extraction step of extracting a key word from the phrase, and It includes key sentence extraction step of extracting key sentence from syntax, document type classification step of classifying document type, and document vector summary generation step of generating document summary information.

In addition, the document summary information generated by the above step is searched in the document processing rule database to search for a rule corresponding to the document type, and use the same to classify the authority level of the document into the most important, important, normal, or less important. In addition, the document permission level can be applied in various ways.

The document type criteria generated in the document type classification step may be classified into confidential, research and development, sales, customer information, and the like, and may be classified according to the user's document use level according to the classified document authority level and document type. It is characterized by taking one or more appropriate measures. Appropriate measures are to block the output of the document, notify the administrator when the document is printed, back up the document output information, and generate the document log. When the document is outputted, the document is watermarked using at least one or more combinations of document level level, document generation management information, document password information, and document access management information as document management identification information.
