Description:
[0001]     This application is based on an application No. 2005-101976 filed in Japan, the contents of which are hereby incorporated by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a method and a system for scanning original image by using an image reading apparatus and an information processing apparatus connected with each other over a network.  
         [0004]     2. Description of the Related Art  
         [0005]     There is known a system for reading an original in which an image reading apparatus (e.g. scanner) or an image processing apparatus having a function of converting information recorded on a media such as paper (original information) to image data capable of being processed by an electronic computer, that is, a scanning function, is connected with a network using a communication line or the like, and the image reading apparatus is operated by an operator from an electronic computer such as a personal computer connected with the network, and the scanner executes scanning and the operator acquires the obtained image data over the network. In such a system, the electronic computer operated by the operator is called a client, and a device which actually instructs a scanning function to the image reading apparatus in accordance with an instruction input by the operator and manages the saving destination of the image data obtained through the scanning is called a scanner server. The client and the scanner server may not be separate devices, and the client may have the server function therein.  
         [0006]     The above-mentioned network includes the Internet, a network using virtual private network (VPN) etc., and local area network (LAN).  
         [0007]     Further, there is a system in which scanning is performed in a configuration where an electronic computer operated by an operator and an image reading apparatus are connected one to one.  
         [0008]     In any system configuration described above, an operator must input, to the scanner or the client before scanning is executed, so-called information about scanner settings and about storage destination of image data, such as the size of the original to be scanned, scanning resolution, color scanning or monochrome scanning, saving destination of image data obtained through scanning, file format of the image data, and a file name etc. This input may sometime be a very troublesome work for the operator.  
         [0009]     Therefore, there have been developed a method and a system enabling an operator of the client to input scanner settings and the like easily and enabling to acquire image data obtained through scanning easily.  
         [0010]     Japanese Patent Application Laid-open No. 2001-028655 provides a system in which the operator can set an address in a scanner using a client. In the system disclosed in the Japanese Patent Application Laid-open No. 2001-028655, the address set in a scanner can be set without using a server. This improves operability of the operator in changing and registering the address of the data transmission destination.  
         [0011]     Japanese Patent Application Laid-open No. 06-004642 provides an image data management system wherein operations for inputting image data and managing it as personal data and outputting it are simplified. In the system disclosed in the Japanese Patent Application Laid-open No. 06-004642, image data (or its pointer) is recorded on a storage medium provided in the network in accordance with information stored on a portable storage medium, and the data can be read out from the storage medium and printed easily. This system contributes to promote paperless environment in offices.  
         [0012]     Japanese Patent Application Laid-open No. 2003-244377 provides a scanner server wherein setting of a scanner and data format of image data can be performed easily. The scanner server according to the Japanese Patent Application Laid-open No. 2003-244377 displays a virtual file on the client, the file name of which includes settings of the scanner and a data format of the image data to be obtained, etc., and when the operator selects a virtual file having desired scanner setting etc., the scanner scans the image data under the settings indicated as the file name of the virtual file, and the image data obtained through the scanning is stored in the virtual file selected by the operator. Thereby, the operations for the scanning become easier.  
         [0013]     However, when setting the settings of the scanner and/or settings of the storage destination of image data obtained through the scanning, these setting operations are still troublesome, and these operations are to be performed on the scanner or the client. Further, there is a case where a dedicated application program is required for these setting operations.  
         [0014]     Further, in order to save image data obtained through the scanning in the client, at least a part of the storage area of the client is required to be in a readable/writable state to the network. Hence this requirement causes a security problem. The present invention has been developed in view of the above-described problems.  
       SUMMARY OF THE INVENTION

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0030]     Preferred embodiments of the present invention are described in more detail below referring to the accompanying drawings.  
         [0000]     (System Configuration)  
         [0031]      FIG. 1  is a schematic diagram showing a system according to an embodiment of the present invention.  
         [0032]     The present system includes a digital complex machine (hereinafter referred to as multifunction peripherals (MFP))  10  having a scanning function. The MFP  10  is connected with a client personal computer (PC)  20  which is an information processing apparatus and a server  30  over a network  100 . Although the present system is configured to include one MFP  10  in  FIG. 1 , a plurality of MFPs may be included in the system.  
         [0033]     The client PC  20  may be an electronic computer, and also be a personal computer having an interface capable of connecting with the network  100 .  
         [0034]     The scanner server  30  is a server which enables the scanning function of the MFP  10  to be used within the network  100 . The scanner server  30  may be composed of a personal computer having a specification required to realize the scanner server function and an application program for realizing the scanner server function. Note that the scanner server function provided by the scanner server  30  may be realized in the client PC  20 . In such a case, the scanner server  30  is not required to exist within the network  100  independent from the client PC  20 .  
         [0035]     Referring to  FIG. 1 , the present system is configured to include one client PC  20  and one scanner server  30 . However, both of them may be provided in plural numbers, respectively. In such a case, the client PC  20  explained in the following description of the present system means a personal computer used by an operator.  
         [0036]     The network  100  may be a network using a public circuit such as the Internet, or a network using a privately used circuit such as a LAN. Further, the network  100  may be a LAN connected with the Internet. Further, the network  100  includes a topology (connection mode) using a means for point-to-point connection (e.g., a USB cable) for connecting the client PC  20  also having the scanner server function and the MFP  10 .  
         [0037]     The MFP  10  is capable of providing, inside its body, a so-called shared folder (Box)  101 , that is, a shared storage area, which can be shared over the network  100 . The Box means a storage area being at least a part of the storage of the MFP  10  and is readable/writable over the network  100 . For example, The Box is divided into a plurality of partitions, each of which is a storage area where only a registered user can use privately. Further, the client PC  20  and the scanner server  30  are also capable of providing shared storage areas, or so-called shared folders  201  and  301 , which can be shared over the network  100 . In the present system, there is required at least one of the shared folder (Box)  101  and the shared folders  201  and  301  in the whole system. For example, if the shared folder  301  is provided in the scanner server  30 , there is no need to provide the shared folder  201  in the client PC  20 , which is readable/writable over the network  100 . It is advantageous to improve the security of the client PC  20  to provide at least one of the shared folder (Box)  101  and the shared folder  301  either in the MFP  10  or in the scanner server  30 .  
         [0038]     Next, the configuration of the MFP  10  will be described with reference to  FIG. 2 . The MFP  10  used in the present system is connected with the network  100  via a communication unit  123 . The communication unit  123  is controlled by a system controller  110 , and is also connected with a memory  102  also controlled by the system controller  110 . The memory  102  has the shared folder (Box)  101 . Further, the system controller  110  is connected so as to be able to control an image processing controller  121  and a scanner controller  122 . The scanner controller  122  controls an imaging unit  141  which optically scans an original placed. The image processing controller  121  controls the image processor  131  which processes optical image information having been processed electrically and being inputted from the imaging unit  141 . The image processor  131  is connected with the memory  102  so as to be able to perform inputting and outputting of information with the memory  102 .  
         [0039]     When operating the MFP  10  itself, an operator operates an operation/display unit  124  so as to input information. The inputted information is transmitted to the system controller  110 . Further, the MFP  10  provides information to the operator via the operation/display unit  124  under the control of the system controller  110 . A program controlling the operation of the MFP  10  is stored on a storage (RAM, ROM, HDD or the like not shown in the  FIG. 2 ) in the system controller  110 , and is executed by the CPU (also not shown in the  FIG. 2 ) in the system controller  110 .  
         [0040]     In general, in addition to the scanning function, the MFP  10  has a copying function, a printing function, a facsimile transmission function and the like. The MFP  10  of the present invention is also capable of performing such functions, but the functions other than the scanning function have little relationship with the present invention, so configuration blocks for such functions are not shown and explanation is also omitted.  
         [0041]     Next, the configuration of the client PC  20  will be described with reference to  FIG. 3 . The client PC  20  includes a central processing unit (CPU)  210 . The CPU  210  is connected with a read-only memory (ROM)  203  and random access memory (RAM)  204  which are main storages and a hard disk drive  202  which is an auxiliary storage, via a data bus  211 . The hard disk drive  202  can have a storage area for a shared folder  202  therein. Further, the CPU  210  is connected with a display controller  221 , a communication controller  222  and an operation controller  223 , via the data bus  211 . The display controller  221  is connected with a display  231 , and the operation controller  223  is connected with a keyboard  233   a  and a mouse  233   b  which is a pointing device. The display  231 , the keyboards  233   a  and the mouse  233   b  constitute interfaces between the operator and the client PC  20 . The communication controller  222  has connection means with the network  100 , and performs transmission/reception of information with external equipment over the network  100  under the control of the CPU  210 .  
         [0042]     Since the configuration of the scanner server  30  may be same as that of the client PC  20 , explanation of the scanner server  30  is omitted.  
         [0043]     The client PC  20  and the scanner server  30  store, in the respective storages, application programs required to perform the present system, and the respective CPUs are capable of executing the application programs.  
         [0000]     (Overview of Image Link Object)  
         [0044]     Prior to detailed explanation of a image reading method, an image link object will be explained in brief. The image link object is an object created within the client PC  20  by the operator. An image link object includes a plurality of data areas such as: a scanner setting information data area for recording information about settings of the scanner (color mode, output file format, image quality, resolution, original size, etc.); a scanner data area for recording information about the MFP used for scanning; and a storage destination information data area of image data for recording information about storage destination of an image data file obtained through scanning and the file name of the image data file. The scanner setting information data area is capable of incorporating a plurality of data areas such as an attribute information data area for recording information about attributes (hidden file, access limit, encryption, etc.) of an image data file, but the scanner setting information data area is only required to be associated with the plural pieces of such data. In some cases, the scanner setting information data area is capable of including a decryption key etc. information data area for recording information about a decryption key and the like.  
         [0045]     When a created image link object is opened (e.g., double-clicked), an image data file stored based on the storage destination information can be read. That is, it is possible to set the image link object linked with the stored image data file.  
         [0046]     Further, an image link object can be created at any hierarchy (level) of the storage within the client PC  20 . If the shell of an operating system (OS) has a graphical user interface (GUI), the image link object is displayed as an icon with a prescribed design. The client PC  20  has an OS provided with a GUI, so the image link object is displayed as an icon with a prescribed design. In the present embodiment, the image link object is called “shortcut to a scanned document” after a shortcut icon provided in the Windows (registered trademark) manufactured by Microsoft. However, “shortcut icon” provided in the above-mentioned OS, Windows, and “shortcut to a scanned document” in the present invention is clearly different. The details will become clear in the following explanation.  
         [0000]     (Image Reading Procedure)  
         [0047]     Hereinafter, an image reading method in an image reading system according to the present embodiment will be described with reference to flowcharts shown in  FIGS. 4, 6  and  7  and  FIGS. 5A, 5B ,  5 C,  5 D,  5 E,  5 F,  5 G,  5 H,  5 I, and  5 J.  FIG. 4  is a flowchart showing a part relating to an image link object creating process of a program which is stored on the storage  202 ,  203  or  204  of the client PC  20  and is installed so as to be executable by the CPU  210 . Now, referring to  FIG. 4  and  FIGS. 5A, 5B ,  5 C,  5 D,  5 E,  5 F,  5 G,  5 H,  5 I, and  5 J, a process from a creation of an image link object (shortcut to a scanned document) to a transmission of a one-touch key creation request to the MFP will be described.  
         [0048]     First, an operator inputs an image link object setting instruction to the client PC  20  by using input devices such as the keyboard  233   a  and the mouse  233   b  (step (S 101 ).  
         [0049]      FIGS. 5A, 5B ,  5 C,and  5 D are illustrations showing examples of the input of the image link object setting instruction performed by an operator. The operator displays a folder to which he/she desires to create an image link object in the display  231  of the client PC  20 , and moves a mouse pointer  501  into a window showing the contents of the folder ( FIG. 5A ). In such a state, when the operator clicks the right button of the mouse for example, a context menu  502  is displayed ( FIG. 5B ). The operator points a menu “New”  502   a  in the displayed context menu. Then, objects which can be newly created are displayed in the sub menu  503  ( FIG. 5C ). The operator points “Shortcut to a scanned document”  503   a  in the sub menu  503 , and clicks the left button of the mouse ( FIG. 5D ). Thereby, the client PC  20  accepts the image link object setting instruction performed by the operator (step S 101 ).  
         [0050]     Now, back to  FIG. 4 , the present program which accepted the image link object setting instruction creates an image link object (step S 102 ). Here, prior to the creating step S 102 , in order to create an image link object, input of information for the image link object by the operator may be accepted.  FIGS. 5E, 5F ,  5 G,  5 H, and  5 I are examples of information input windows.  FIG. 5J  is an illustration showing an exemplary display of the created image link object.  
         [0051]     A first dialogue box  510  for “Creation of shortcut to a scanned document” is displayed on the display  231  ( FIG. 5E ). In the first dialogue box  510 , selection of a scanner to be used, designation of a storage destination folder and a file name of image data obtained by the scanning (storage destination of the scanned document), and setting of the attributes of the image data file (hidden file, access limit, encryption, etc.) can be performed. Hereinafter, these settings will be described.  
         [0052]     Devices currently capable of using the scanner function via the network  100  are displayed in the list box  511 . A scanner to be used is selected by the operator from the list box  511 . A Settings button  512  positioned on the right side of the list box  511  will be explained later with reference to  FIG. 5F .  
         [0053]     A storage destination folder and a file name of an image data file obtained through scanning (storage destination of the scanned document) are input from a text box  513  by the operator. Here, available storage destinations are shared folders (Boxes)  101 ,  201  and  301  existing within the network  100 , and available file name to be input in the tail end portion of the text box  513  (in figure, “0001.jpg”) is an arbitrary character string. In order to simplify the input, a file name may be created automatically as a sequential number from the file name previously used (e.g., “0001.jpg”), or a date when the object is created may be input automatically as a file name (e.g., “20050401.jpg”) by using a internal clock of the client PC  20 . An extension attached to the end of the file name may be input manually so as to designate the file format, but it may be added or changed automatically based on the setting of the output format described later. Although a storage destination is input in a text box format in this example, addresses of the shared folders (Boxes)  101 ,  201  and  301  within the network  100  may be selectable from a list box, and the input of the file name may be performed using a separate text box.  
         [0054]     The attributes of an image data file are set by using a check box  515 . Here, a hidden file means to give invisible attribute to an image data file obtained through scanning. The existence of the image data file to which invisible attribute is given is not displayed even if the shared folder in which the file is saved is displayed. Therefore, even when a third party views the shared folder in which the image data file is saved, it is difficult that the third party recognizes the existence of the image data file, so an improvement in security is expected. In this case, the substance of the image data file is also invisible to the operator, but the image data file can be read out without any problem by using an image link object as described later. Next, an access limit is a setting to authorize accesses to an image data file using an image link object and not to authorize other accesses, that is, accesses performed not using the image data object. Besides, it is also possible to give an access limit to an image data file by a user name logged in the network  100 , and an access limit to an image data file by a client machine used for the access. An encryption attribute is an attribute to instruct the MFP  10  to encrypt the image data by using encryption and decryption algorithms.  
         [0055]     Next, referring to  FIG. 5F , setting of a scanner will be described.  FIG. 5F  illustrates an example of a “Scanner settings” dialogue box  520 . The dialogue box  520  is displayed by pressing the Settings button  512  of the dialogue box  510 .  
         [0056]     The operator can display the “Scanner Settings” dialogue box  520  by pressing the Settings button  512  displayed on the upper right part of the first dialogue box  510  for “Creation of shortcut to a scanned document”. The dialogue box  520  has two panels, that is, a “Basic Settings” panel and an “Advanced Settings” panel (not shown). Display switching between the two panels can be performed by pointing a “Basic Settings” tab control  522   a  or a “Application Settings” tab control  522   b  with the mouse pointer  501 , and clicking the mouse  233   b.  The “Basic Settings” panel displays current settings of the MFP  10  used for scanning, that is, a part of scanner setting information. The operator can change these settings  521   a,    521   b,    521   c,    521   d,  and  521   e  displayed in the list box format by manipulating the mouse  233   b.  The basic settings include:  
         [0057]     Color mode (can be set in multi-steps from full color to monochrome),  
         [0058]     Output format (JPEG, TIFF, PDF, PNG, BMP, etc.),  
         [0059]     Image quality (character, photograph, figure, etc.),  
         [0060]     Resolution (can be set in multi-steps by dpi unit, etc.), and  
         [0061]     Original size (including a manual setting of the original size in multi-steps by the operator and a setting for an automatic determination of the original size by the MFP  10 ) and the like. After changing and confirming the settings, the operator can validate the settings by manipulating (clicking) the OK button  523  with the mouse  233   b.    
         [0062]      FIG. 5G  illustrates a method of input on “Scanned document storage destination”. The operator points inside a text box  513  with the mouse pointer  501  and clicks the mouse  233   b  whereby a cursor is displayed. In this state, the operator can input the storage destination of the scanned document from the keyboard  233   a.  When a “Browse” button  514  set on the right side of the text box  513  is clicked, the shared folders (Boxes)  101 ,  201  and  301  within the network  100 , that is, shared storage areas, are displayed, so that the storage destination of the image data file can be selected easily by using the mouse or the like.  
         [0063]      FIG. 5H  illustrates a method of setting attributes of the image data file, that is, a method of inputting attribute information. The operator points each check box of a group of attribute check boxes  515  with a mouse pointer  501 , and clicks the mouse  233   b  . For each attribute, valid and invalid is switched by each click. A valid attribute is checked, like a hidden file attribute. It is possible to perform detailed settings for each attribute by clicking a “Advanced” button placed on the right side of the group of check boxes  515 . In the detailed (Advanced) settings, detailed access limit settings for the access limit attribute and detailed settings for encryption and decryption can be done, for example.  
         [0064]     When input of information in the first dialogue box  510  is completed, the operator clicks a “Next” button  516  with the mouse  233   b.    
         [0065]     Then, the present program displays a second dialogue box  530  for “Creation of shortcut to a scanned document” (see  FIG. 5I ). The second dialogue box  530  has one text box  531 . In the text box  531 , the operator can input the name of an image link object (shortcut to the scanned document) itself. The inputting method may be same as the above-described method of inputting into the text box  513 . Further, in order to reduce the workload of the operator, the name may be created automatically as a sequential number (e.g., “0002”) from the name of the image link object previously created (e.g., “0001”), and displayed on the text box  531  in advance. Alternatively, the name may be created automatically based on the current date by using an internal clock of the client PC  20  and displayed on the text box  531  in advance. Besides, the name of the object may be created automatically by combining the user name, the name of the client PC  20  in the network  100 , or the like, and displayed. After g inputting the name of the object, the operator clicks an “Finish” button  532  with the mouse  233   b.    
         [0066]     By pressing the Finish button  532 , the present program creates the image link object within a folder in a desired storage hierarchy of the client PC  20  (step S 102 ). Further, it is possible to create the image link object in an arbitrary hierarchy of a storage which is provided outside the client PC  20  and is connected with the network  100  and is readable/writable by the client PC  20 .  FIG. 5J  shows an example of displaying a folder in which the created image link object exists. An image link object named “0001” is displayed together with other files existing within the same folder.  
         [0067]     Back to  FIG. 4 , next, a one-touch key creation request which includes information for requesting an execution preparation of scanning, that is, scan preparation information, including scanner setting information and storage destination information, is transmitted to the MFP  10  (step S 103 ). If there are plural devices having scanning function connected with the network  100 , the request is transmitted to a scanner to be used for scanning based on the information stored on or related to the scanner data area of the image link object. Further, it may be planned that the scan preparation information including scanner data is transmitted to all devices having the scanning function, and each of the devices received the information examines the scanner data and if the request is not related to oneself, the device disregards it. The one-touch key creation request may include, information indicating a request for one-touch key creation, and scanner data information designating a scanner to be used (e.g., MFP  10 ) set as described above, scanner setting information about the settings of the scanner to be used, information about a storage destination folder of the image data obtained through scanning and the file name of the image data (storage destination of the scanned document), that is, storage destination information, and information about attributes of the image data, that is, attribute information. Here, a one-touch key means a button provided on the operation/display unit  124  of the MFP  10  ( FIG. 2 ) for instructing, by the operator, the start of scanning. The one-touch key may be different from a standard button provided constantly on the MFP  10  for instructing the start of scanning. Using the one-touch key set on the operation/display unit  124  of the MFP  10 , the operator can instruct to start scanning according to the settings of the image link object with one operation. Thereby, the operator does not have to perform the setting of the scanner or the like by manipulating the operation/display unit  124  of the MFP  10  again and again. This leads to an improvement in operability. Since the MFP  10  of the present embodiment has a display panel, enabling a touch input, on the operation/display unit  124 , the one-touch key is displayed in which a prescribed graphic and character information (the setting state of the scanner, some information about being created image data file such as a file name, the name of the image link object, etc.) are included, and the operator can start a scanning by touching the graphic. Although the scanning is started by pressing the one-touch key in the present embodiment, the pressing may only have the MFP  10  start reading out the scanner setting information and the storage destination information. In such a case, based on the read out information, the information is displayed on the operation/display unit  124 . The actual start of the scanning may be performed with a standard button to start a scanning provided separately.  
         [0068]     Note that there are some scanners which can start a scanning by receiving an instruction from the client PC  20 . In such scanners, step S 114  in  FIG. 6 , described later, may be executed immediately upon a reception of the creation request.  
         [0069]      FIG. 6  is a flowchart showing a part of the process executable by the program, from the start of a scanning upon reception of the one-touch key creation request to the completion of the scanning. This program is stored on a storage (ROM, RAM, HDD, etc.), (not shown,) in the system controller  110  of the MFP  10  and is executable by the CPU, (not shown,) in the system controller  110 . Hereinafter, a process of the MFP  10  after reception of the one-touch key creation request will be described with reference to  FIG. 6 .  
         [0070]     First, the reception of the one-touch key creation request, which is input from the client PC  20  to the communication unit  123  over the network  100  is confirmed (step S 111 ). Next, based on information contained in the one-touch key creation request, the one-touch key is created on the operation/display unit  124  (step S 112 ).  
         [0071]     The operator places an original to be scanned on the MFP 10 , and presses the one-touch key created on the operation/display unit  124 . When the press of the one-touch key is confirmed (step S 113 ), a scanning of the placed original is started based on the settings shown by the information included in the one-touch key creation request, that is, scanner setting information (step S 114 ).  
         [0072]     The scanned image data of the original is stored on the memory  102  temporarily. The data is converted to a data format instructed by the one-touch key creation request, and saved in a shared folder (Box)  101 ,  201  or  301  instructed by the storage destination information contained in the one-touch key creation request.  
         [0073]     With the process described above, the image data of the original is saved in a desired shared folder in a storage hierarchy of storage.  
         [0074]     The storage used for this saving is not necessarily storage within the client PC  20 . Therefore, there is no need to share a part of the storage area of storage of the client PC  20  for transferring the image data file, so it is advantageous to the security.  
         [0075]      FIG. 7  is a flowchart showing a part of the process executable by the program according to the present invention.  FIG. 7  shows a part of the process relating to a display of image data. This program is stored on storage  202 ,  203  or  204  of the client PC  20  and is installed so as to be executable by the CPU  210 .  
         [0076]     After the scanning is completed (step S 115  is completed), the operator operates the client PC  20  so as to execute an operation to the image link object described later, thereby instructing the client PC  20  to display the image data which has been scanned. This instruction may be given by pointing an image link object  550  ( FIG. 5J ) displayed on the display  231  ( FIG. 3 ) with the mouse pointer  501  and double-clicking the mouse  233   b,  for example. When the CPU  210  confirms that the instruction of displaying the image data is inputted (step S 104 ), the CPU  210  obtains, over the network  100 , an image data file (file shown by the information inputted in the storage destination text box  513  of the scanned document (see  FIGS. 5E, 5G , etc.)) linked to the image link object based on information stored in or associated to the image link object, that is, storage destination information and the like (step S 105 ). Then, the CPU  210  displays the obtained image data file on the display  231  (step S 106 ). Further, the program may have a function of obtaining the linked image data file by, for example, right-clicking the image link object and saving it on the folder in which the image link object exists. At this time, it may be programmed that the image link object is deleted automatically when the saving of the image data file is completed. Further, the file name of the obtained image data file may be changed automatically to “name of the image link object”+“.”+extension (suitable for the file format) and saved.  
         [0077]      FIGS. 8, 9 , and  10  are flowcharts of a program, executed by the CPU (not shown) in the system controller  110  of the MFP  10  and CPU  210  of the client PC  20  when the encryption attribute is given to a created image link object. Each flowchart of these shows a part relating to image link object creation processing (processing in which encryption processing is added to the processing shown in  FIG. 4 ), a part relating to processing from reception of a one-touch key creation request to the start of scanning and to the completion of the scanning (processing in which encryption processing is added to the processing shown in  FIG. 6 ), and a part relating to displaying of the image data (processing in which decryption processing of the encrypted image data is added to the processing shown in  FIG. 7 ), respectively.  
         [0078]     If the encryption attribute is validated in the setting of the image link object described above, the process shown in  FIG. 8  is executed by the CPU  210  of the client PC  20 . The process according to step S 201  is same as that of step S 101  ( FIG. 4 ). Since the encryption attribute being validated by the operator in the setting of the image link object (see  FIG. 5E , etc.), an encryption key and a decryption key are created prior to the creation of the image link object (step S 202 ). The creation of an encryption key and a decryption key can be performed using a well-known asymmetric cryptographic algorithm. Alternatively, another cryptographic algorithm such as a common key system may be used. An image link object is created, in a data area of which the information about the decryption key of the created two keys is included (step S 203 ). Alternatively, the information about the decryption key may be saved as a file separately and the image link object may store the information about the file, that is, be associated, instead of storing the information about the decryption key on the data area of the image link object. Then, information about the encryption key is included in the one-touch key creation request and transmitted to the MFP  10 , or the information about the encryption key is transmitted to the MFP  10  together with the transmission of the one-touch key creation request (step S 204 ).  
         [0079]      FIG. 9  is a flowchart showing a part of processing of a program from reception of the one-touch key creation request to the start of scanning and the completion of the scanning. This program is stored on storage (ROM, RAM, HDD, etc.) (, not shown,) in the system controller  110  of the MFP  10  and is executable by the CPU (, not shown,) in the system controller  110 .  
         [0080]     Step S 211  is similar to the step S 111  ( FIG. 6 ). However, the received one-touch key creation request may include an encryption key, or one or more pieces of information about the encryption key may be received together with the reception of the one-touch key creation request. Next, a process from a creation of the one-touch key to an execution of scanning (steps S 212  to S 214 ) is performed in the same manner as steps S 112  to S 114  ( FIG. 6 )  
         [0081]     After a conversion of the image data into a data having the data format instructed in the one-touch key creation request similar to step S 115 , the image data is encrypted based on the encryption key received together with the one-touch key creation request, if the information about the attributes of the image data, that is, attribute information, contained in the one-touch key creation request indicates that the encryption attribute is valid. And the encrypted image data file is saved on a shared folder (Box)  101 ,  201  or  301  instructed in the storage destination information included in the one-touch key creation request (S 215 ).  
         [0082]      FIG. 10  is a flowchart showing a part of process of a program stored on storage  202 ,  203  or  204  of the client PC  20  and is installed so as to be executable by the CPU  210 , relating to display of the encrypted image data file. Similar to steps S 104  and S 105 , the image data is obtained by an instruction from the operator (steps S 205  and S 206 ). Next, in order to display the encrypted image data, the encrypted image data file is decrypted by using a decryption key included in the data area of the image link object or a file including the decryption key indicated by the information about the decryption key stored in the image link object (step S 207 ). Then, the decrypted image data is displayed on the display  231  (step S 208 ). Further, similar to the description relating to step S 106  described above, there may be a function of saving the decrypted image data file in a folder in which the image link object exists after the image data file is obtained by right-clicking the image link object and decrypted, for example. In this case, it is possible to plan the program to delete the image link object automatically when saving of the image data file is completed. Further, the file name of the obtained image data file may be changed automatically to one like “name of the image link object+.+extension (suitable for the file format)” and then saved.  
         [0083]     As described above, an image data file exists as an encrypted data file on the designated shared folder (Box) and the network  100 . Therefore, it is advantageous from the security point of view.  
         [0000]     (Procedure to Change the Image Link Object Settings)  
         [0084]     It is expected that the settings of the created image link object may be required to be changed later. The settings of the image link object once created can be changed in the following manner.  
         [0085]      FIG. 11  is a flowchart of a part of process of a program stored on storage  202 ,  203  or  204  of the client PC  20  and is installed so as to be executable by the CPU  210 . This process relates to the process to change the settings of the image link object.  
         [0086]     An instruction to change the settings of the image link object is inputted by the operator (step S 301 ). This instruction can be inputted by right-clicking the image link object  550  ( FIG. 5J ) so as to refer to the property of the object, for example.  
         [0087]     When the change of settings is inputted, the settings of the image link object are changed in accordance with the contents of the change instruction (step S 302 ) Then, a one-touch key setting change request is transmitted to the MFP  10  (step S 303 ).  
         [0088]      FIG. 12  is a flowchart showing a part of a program relating to processing from reception of a one-touch key setting change request to change of settings. This program is stored on a storage (ROM, RAM, HDD, etc.) (, not shown,) in the system controller  110  of the MFP  10  and is executable by the CPU (, not shown,) in the system controller  110 .  
         [0089]     The MFP  10  confirms a reception of the one-touch key setting change request (step S 311 ). Next, based on the information of the one-touch key setting change request, the settings of the one-touch key currently set, that is, the settings of the scanner in scanning which is started by pressing the one-touch key and the settings relating to the storage destination of the data file to be created are changed.  
         [0090]     Thereby, when it is desired to change the settings of the image link object after the image link object is created, it is possible to use the existing image link object without creating a new image link object. This improves the efficiency of the operation.  
       Example of Modifications of the Present Embodiment  
       [0091]     Instruction of image link object settings is not limited to a usage of a displayed context menu by right-clicking but may include a usage of a Task Panel that contains a command of the image link settings. The Task Panel is an available task list adopted in the Explorer of the Windows XP. Further, an image link setting command may be provided in pull-down menu of the folder.  
         [0092]     An image reading apparatus is not limited to a digital complex machine (MFP) having a scanning function but may be a apparatus having a function of reading images and converting them into data suitable for processing by an information processing apparatus, such as a scanner.  
         [0093]     The client PC  20  may be an information processing apparatus such as an electronic computer like a workstation, or a controller for image reading apparatus capable of operating an image reading apparatus and using shared resources within the network, besides a personal computer.  
         [0094]     In the present specification, the term “original” is not limited to a paper media on which information is recorded by using ink or the like. The original includes information printed on a plastic film or the like, and a photographic film.  
         [0095]     As this invention may be embodied in several forms without departing from the spirit of essential characteristic thereof, the present embodiment is therefore illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description preceding them, and all changes that fall within metes and bounds of the claims, or equivalence of such metes and bounds thereof are therefore intended to be embraced by the claims.
