7 is a signal flow diagram illustrating a mobile office printing procedure based on cloud computing according to an embodiment of the present invention. Referring to FIG. 7, when a user requests an output through a user terminal (eg, a smartphone) (S701), an app program installed in the smartphone is driven (S702), and a user authentication procedure is performed by a service server. (S703).
The service server performs a user check to the database server (S704), and the database server performs a user authentication check (S705) to transmit user authentication information to the service server (S706). The service server encrypts the corresponding user information (S707), and transmits the user information to the corresponding smartphone by a streaming method (S708).
The smartphone generates information recognition means (for example, a QR code) by using the authentication encryption information transmitted from the service server according to an embodiment of the present invention (S709). Then, when the information recognition means of the smartphone is scanned through the scanner provided in the information providing terminal (S710), the information providing terminal recognizes and decodes the scan code (S711). In addition, after checking the integrity of the input code (S712), the preparation for providing the service is completed (S713).

The service server transmits the output result to the database server (S726) to update the information (S727).
On the other hand, according to an embodiment of the present invention, the security of the document should be guaranteed between the server storing the file to be output and the information output terminal. Hereinafter, the security method of the output document will be described in detail with reference to FIGS. 8 to 17.
The P2P-based document authentication and output system includes an application program of a user terminal to which an output document is to be transmitted and an application program of a remote terminal receiving the output document and outputting the output document through a connected information output terminal, after logging on to the service server. The application program of the terminal searches for the remote terminal, and the application program of the user terminal transmits an output metafile in which the output document is converted into a form that can be output to the application program of the remote terminal, The received output metafile is sent to the information output terminal connected to the remote terminal and printed.
The application program is installed in the user terminal or the remote terminal and enables the user terminal and the remote terminal to communicate with each other as user information of the service server. 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.
In addition, the document authentication and output method according to an embodiment of the present invention requests the document output from the application program through the automatic authentication or the procedure of authenticating the requestor when the document output request. The application program extracts the text of the document before calling the document to the printer by calling GDI, and performs a language analysis of the extracted text through a language processing procedure to check the security of the document. 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.
In addition, the document authentication and output method according to an embodiment of the present invention, in the case of a document that went through the appropriate procedure as described above, in order to be able to output directly to the remote party, a program having a P2P messaging function, When outputting, the terminal retrieves, registers, and inputs information of a destination. The program includes a security authentication function, a constraint on the output document, a print frequency, an output authentication code, and the like, for secure transmission of the output document.
In this case, the preferred embodiment will be described. When the head office sends a print document directly to a branch in Alaska, when the head office sends a print document to a specific recipient in Alaska or to a group, the print document information is sent to the printer's account information. The print document is generated in the form of a document, and the print document is compatible with any terminal. The generated document file calls the native print driver. The generated document file is transferred to the destination through the Internet and a dedicated network connection method. The document file adds a security authentication function. The document file combines one or more security elements among a receiver's authentication code, a receiver IP address, and a receiver registry information. In addition, when the receiving side is offline, the document file is stored in the server. After that, when the receiver is online, the document file is automatically sent and printed. When printing is completed, it is automatically deleted from memory according to the rules of security authentication.
