  As shown in the figure, the platform unit 220 includes an SRM (System Resource Manager) 222, a network management process 224, an authentication server process 226, a download process 228, a panel management process 230, a print management process 232, And a general-purpose OS 240. The platform unit 220 also includes a secondary storage access library 234 that is a file for accessing the secondary storage device 610.

  The SRM 222 is a process for performing arbitration and executing control according to a request from an upper layer that uses hardware resources constituting the image forming apparatus 200. Specifically, it is determined whether the requested hardware resource is available, and if it is available, the upper layer is informed that the requested hardware resource is available. The SRM 222 includes an SCS (System Control Service) 223 as shown in FIG. The SCS 223 is a process for managing each application and hardware resources.

  The network management process 224 is the access point means of the present invention. The network management process 224 receives various data received from the terminal device 300 and the Web server 400, and sends the received various data to each process by inter-process communication.

  The authentication server process 226 is user authentication means of the present invention. The authentication server process 226 executes a user ID and password authentication process. Specifically, the user ID and password stored in advance in the secondary storage device 610 are expanded on the RAM 620. Then, authentication is performed by collating the password received from the outside with the password corresponding to the user ID developed on the RAM 620. As described above, the user ID and the encrypted password recorded in advance in the secondary storage device 610 are developed in advance on the RAM 620, whereby the authentication process can be speeded up.

  The download process 228 first records this document data in the RAM 620 and stores all of the document data in the RAM 620 and saves it in the secondary storage device 610. Usually, the secondary storage device 610 is often of a type called a block device (for example, HDD), and it often takes time to access each time. For this reason, if document data is transferred to the secondary storage device driver every time a part of the document is downloaded, there is a problem that it takes time for the saving process. Therefore, before storing in the secondary storage device 610, all the document data from the Web server 400 is recorded in the RAM 610 collectively, thereby reducing the number of accesses to the secondary storage device and improving the performance of the download process. Can be raised.

  The panel management process 230 controls the operation panel 640. The print management process 232 prints the document data stored in the secondary storage device 610 by the download process 228 using the monochrome line printer 700 or the color line printer 710.

  The general-purpose OS 240 is a general-purpose operating system such as UNIX (registered trademark), for example, and executes software of each application of the platform unit 220 and the application unit 210 as a process.

  The activation unit 250 activates the application unit 210 and the platform unit 220 when the image forming apparatus 200 is powered on.

  Returning to FIG. 1 again, the Web server 400 stores various document files (document data), and distributes the document files to the image forming apparatus 200 via the Internet 501 in response to a request from the image forming apparatus 300. To do.

  In the above configuration, each process performed in the image forming service system 100 according to the present embodiment will be described. In the image forming service system 100, user authentication processing, document download processing, and document printing processing are executed.

  First, user authentication processing performed in the image forming service system 100 will be described with reference to FIG. FIG. 4 is a sequence diagram illustrating a procedure of user authentication processing performed in the image forming service system 100. It is assumed that the image forming apparatus 200 and the terminal apparatus 300 are wirelessly connected by the WEP encryption method. In addition, transmission / reception between the image forming apparatus 200 and the terminal apparatus 300 described below is performed via a wireless LAN driver.

  First, when the user activates the Web browser 322 using the terminal device 300 (step SA-1), the terminal device 300 connects the authentication screen 360 (see FIG. 5-1) to the image forming apparatus 200. A request is made (step SA-2).

  Upon receiving the authentication screen connection request from the terminal device 300, the network management process 224 of the image forming apparatus 300 responds to the request by transmitting an HTML-format authentication screen 360 (step SA-3). .

  Upon receiving the HTML-format authentication screen 360, the terminal device 300 displays the authentication screen 360 on the Web browser 322, and accepts the input of the user ID and password in the user ID input field 360a and the password input field 360b (step) SA-4).

  When the transmission button 360c is pressed, the terminal apparatus 300 transmits the user ID and password input by the user to the image forming apparatus 200 (step SA-5).

  Upon receiving the user ID and password from the terminal device 300, the network management process 224 of the image forming apparatus 200 passes the received user ID and password to the authentication server process 226 (step SA-6).

  The authentication server process 226 receives the user ID and password from the network management process 224, and executes authentication processing (step SA-7). The details of the authentication processing procedure in step SA-7 will be described later.

  The authentication server process 226 passes the authentication result of the authentication process at Step SA-7 to the network management process 224 (Step SA-8). When the network management process 224 receives the authentication result from the authentication server process 226, the network management process 224 transmits the received authentication result to the terminal device 300 (step SA-9).

  Upon receiving the authentication result transmitted in step SA-9, the terminal device 300 displays the authentication result on the web browser 322 (step SA-10). Specifically, when the authentication result from the image forming apparatus 200 is successful, a screen (authentication success screen 362) notifying that the authentication is successful is displayed as shown in FIG. On the other hand, if the authentication result from the image forming apparatus 100 is unsuccessful, a screen (authentication failure screen 364) notifying that the authentication has failed is displayed as shown in FIG.

  Here, the authentication process performed by the authentication server process 226 performed in step SA-7 will be described with reference to FIG. FIG. 6 is a flowchart showing a procedure of authentication processing by the authentication server process 226. It is assumed that the user ID and the encrypted password stored in the secondary storage device 610 are expanded on the RAM 620 in advance.

  First, from the network management process 224 that has received the user ID and password from the terminal device 300, the user ID and password are received by inter-process communication (step SA-71). Next, the password received in step SA-71 is encrypted (step SA-72).

  Next, the password encrypted in step SA-72 is compared with the encrypted password in RAM 620 read in advance when the authentication server process 226 is initialized (step SA-73). As a result of verification, if the passwords match, the authentication is successful, and if the passwords do not match, the authentication fails.

  As a result of the collation in Step SA-73, if the authentication is successful (Step SA-74: Yes), a notification of successful authentication is passed to the network management process 226 by inter-process communication (Step SA-75). In other words, the HTML format authentication success screen 362 (see FIG. 5-2) is passed.

  On the other hand, if the authentication fails as a result of the collation in step SA-73 (step SA-74: No), a notification of the authentication failure is passed to the network management process 226 by inter-process communication (step SA-76). ). In other words, an HTML format authentication failure screen 364 (see FIG. 5-3) is passed.

  As described above, since only the Web browser 322 is required for authentication, no special hardware is required, and the image forming service can be used by more terminal devices 300.

  Here, the initialization process of the authentication server process 226 will be described with reference to FIG. FIG. 7 is a flowchart showing a procedure of initialization processing of the authentication server process 226.

  First, an authentication server process 226 is generated in response to a request from the network management process 224 (step SB-1). For example, in the case of UNIX (registered trademark), the process is forked.

  The authentication server process 226 generated in step SB-1 acquires the user ID and password (authentication information) from the secondary storage device 610 (step SB-2). Then, the user ID and password acquired in step SB-2 are expanded on the RAM 620 (step SB-3).

  When the process of step SB-3 is completed, the authentication server process 226 enters a sleep state until receiving some request. The means for shifting to the sleep state is, for example, sleep () that exists in the general-purpose OS 240.

  Next, document data download processing performed in the image forming service system 100 according to the present embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram illustrating a procedure of document data download processing performed in the image forming service system 100. The download process 228 is assumed to be in a sleep state.

  First, after the authentication result by the above-described authentication processing is successful, when the user downloads the document download button 362a on the authentication success screen 362 shown in FIG. The apparatus 300 sends a download transmission request to the image forming apparatus 100 (step SC-1).

  Upon receiving a download transmission request from the terminal device 300, the network management process 224 of the image forming apparatus 100 issues an activation request to the download process 228 (step SC-2).

  Next, when the download process 228 receives the activation request from the network management process 224, the download process 228 transmits an HTML-format address information designation screen 370 (see FIG. 9) to the terminal device 300 via the network management process 224 ( Step SC-3).

  Next, when receiving the address information designation screen 370, the terminal device 300 displays the address information designation screen 370 on the Web browser 322. Then, the user designates the URL of the Web server 400 that stores desired document data as address information (step SC-4).

  When a URL is input as address information in the URL input field 370a on the address information designation screen shown in FIG. 9 and the OK button 370b is subsequently pressed, the terminal apparatus 300 sends the address information to the image forming apparatus 200. Transmit (step SC-5).

  Next, when the network management process 224 receives the address information transmitted from the terminal device 300 in step SC-5, it passes the received address information to the download process 228 (step SC-6).

  Next, when the download process 228 receives the address information from the network management process 224, the download process 228 acquires the document data from the Web server 400 corresponding to the address information (step SC-7), and the acquired document data is stored in the secondary storage device 610. (Step SC-8). The procedure of the download process by the download process 228 will be described later in detail.

  Next, the download process 228 passes the download acquisition result to the network management process 224 through inter-process communication (step SC-9). Next, the network management process 224 transmits the acquisition result received from the download process 228 to the terminal device 300 (step SC-10).

  In this way, the user can print on the image forming apparatus 300 side simply by specifying the URL of the document data to be printed from the terminal apparatus 300. Therefore, even when different types of image forming apparatuses 200 are used for each access point, it is not necessary to install a printer driver corresponding to each image forming apparatus 200. Even if the terminal device 300 of the user cannot install the printer driver, the image forming service can be used.

  Here, download processing by the download process 228 will be described with reference to FIG. FIG. 10 is a flowchart showing the procedure of download processing by the download process 228. It is assumed that the download process 228 is in a sleep state by the sleep function of the general-purpose OS.

  First, the download process 228 is activated by an activation request from the network management process 224 through inter-process communication (step SD-1). Next, an HTML-format address information designation screen 370 is transmitted to the terminal device 300 via the network management process (step SD-2). Then, the process is put to sleep until the designated address information is received from the terminal device 300 (step SD-3).

  Next, when the designated address information is received, the process is restarted (step SD-4). Then, connection to the Web server 400 corresponding to the URL that is the received address information is attempted via the Internet 501 (step SD-5).

  In step SD-5, the connection process is performed, and if the connection destination URL exists (step SD-6: Yes), the document file from the Web server 400 is recorded in the RAM 620 (step SD-7).

  Next, when all the data of the document file is recorded in the RAM 620, the document file recorded in the RAM 620 is stored in the secondary storage device 610 via the driver of the secondary storage device 610 (step SD-8). Then, a successful download screen in HTML format is passed to the network management process 224 by inter-process communication (step SD-9).

  On the other hand, when connection processing is performed in step SD-5 and there is no connection destination URL such as an error returned by HTTP (step SD-6: No), the network management process 224 is communicated by inter-process communication. An HTML format download failure screen is handed over (step SD-10).

  Next, document data printing processing performed in the image forming service system 100 according to the present embodiment will be described with reference to FIG. FIG. 11 is a sequence diagram showing a procedure of document data print processing performed in the image forming service system 100.

  First, the download document print screen 380 shown in FIG. 12A is displayed on the screen of the operation panel 640, and the user ID and password are accepted (step SE-1). By the operation of the operation panel 640 by the user, the user ID is input to the user ID input field 380a and the password is input to the password input field 380b on the download document print screen 380, and then the OK button 380c is pressed. Then, the operation panel 640 sends the input user ID and password to the authentication server process 226 (step SE-2).

  Next, upon receiving the user ID and password from the operation panel 640, the authentication server process 226 performs authentication processing (step SE-3). This authentication process is the same as the authentication process performed by the authentication server process 226 shown in FIG.

  The authentication server process 226 sends an authentication result obtained by the authentication process in step SE-3 to the operation panel 640 (step SE-4). When the operation panel 640 receives the authentication result from the authentication server process 226, the operation panel 640 displays the authentication result on the screen (step SE-5). Specifically, when an authentication result indicating successful authentication is received from the authentication server process 226, an authentication success screen 382 shown in FIG. 12-2 is displayed to notify that the authentication has been successful. On the other hand, when an authentication failure authentication result is received from the server process 226, an authentication failure screen 384 shown in FIG. 12-3 is displayed to notify that the authentication has failed.

  When the authentication success screen 382 shown in FIG. 12-2 is displayed in step SE-5, the user selects desired document data from the document data in the document data selection field 382a (step SE-6). When document data is selected in step SE-6 and the print button 640a is subsequently pressed, the operation panel 640 issues a print request to the print management process 232 (step SE-7).

  When receiving a print request from the operation panel 640, the print management process 232 acquires a document file related to the print request from among the document files stored in the secondary storage device 610 (step SE-8). Then, the print management process 232 sends the acquired document data as a print document to the printer driver (step SE-9).

  Next, the printer driver performs print processing for the print document received from the print management process 232 (step SE-10).

  According to the image forming service system 100 of the present embodiment, the image forming apparatus 200 acquires the user ID and password from the terminal apparatus 300 via the wireless LAN 500 by the network management process 224, and performs inter-process communication. Since the authentication process is performed by the authentication server process 226 using the user ID and password acquired from the network management process, when the image forming apparatus 200 communicates with the terminal apparatus 300 via a wireless LAN, an authentication server is separately installed. Therefore, space saving of the hot spot can be achieved.

  Further, the image forming apparatus 200 receives the user ID and password from the terminal device 300 by the network management process 224, and the authentication server process 226 encrypts the received password, and encrypts the encrypted password and the encrypted password in advance. Authentication processing is performed by comparing the encrypted password. That is, since the password stored in the secondary storage device 610 is encrypted, it is possible to make it difficult to decrypt the password even if there is an unauthorized access to the image forming apparatus 200. Leakage can be prevented.

  Further, when the image forming apparatus 200 executes the initialization of the authentication server process 226, the user ID and the encrypted password stored in the secondary storage device 610 are preliminarily developed in the RAM 620, so that the authentication server Since the process 226 collates the encrypted password developed in advance in the RAM 620 with the password from the terminal device 300, the performance of the authentication process can be improved.

  Further, the terminal device 300 transmits the URL specified by the user as address information to the image forming apparatus 200, and the image forming apparatus 200 receives a document file from the Web server 400 corresponding to the URL by the download process 228. When the data of all the document files is recorded in the RAM 620, the data of the document file recorded in the RAM 620 is stored in the secondary storage device 610. Therefore, the number of accesses to the secondary storage device 610 can be reduced. The efficiency of the download process can be increased.

  Further, the terminal device 300 transmits a URL (address information) designated by the user to the image forming apparatus 200, and the image forming apparatus 200 acquires document data from the Web server 400 of the URL, and acquires the acquired document. Since the data is printed, the user can obtain a printed document by only specifying the address information of the document data to be printed from the terminal device 300 without installing a printer driver.

  Further, the image forming apparatus 200 receives a document data print request from the operation panel 640, and among the document data saved in the secondary storage device 610 by the download process 228, the document data related to the received print request is printed on a print sheet. Since printing is performed, the user can collect the printing paper on which the document has been printed on the spot, and can prevent others from viewing the document when a print request is made from a remote location.

  Further, when the image forming apparatus 200 receives a document data print request from the operation panel 640, the image forming apparatus 200 displays a document print screen 380 on the screen, allows the user to input a user ID and a password, and inputs the input. Since the authentication process is performed using the user ID and the password, and when the user is authenticated by the authentication process, the authentication success screen 382 is displayed and the print request for the document data is accepted. Prevention can be strengthened.
