<< Configuration of Scanner System of Embodiment 1 >>
FIG. 1 is a diagram illustrating an overview of a system according to the first embodiment of the present invention. In FIG. 1, a digital multi-function peripheral 10, a file server 20, and a plurality of personal computers 31, 32, 33, 34,..., 39 (PC1, PC2, PC3, PC4,..., PCn) are mutually connected via a network such as an in-house LAN. Connected in a communicable state. The system according to the present embodiment is centered on the digital multifunction peripheral 10 constituting the system and a personal computer (for example, 31) using the system, and performs information processing using the file server 20 as necessary. Various functions are realized.

A digital multifunction device 10 shown in FIG. 1 includes an image scanning unit 11 that scans an image and converts it into an electrical signal, a printing unit 12 that prints and outputs an image on paper, and a control unit that controls the entire digital multifunction device 10. 13. A storage unit 14 that stores setting contents, an operation unit 15 that is operated by a user to set operation contents, and a display unit 16 that displays the operated contents, input contents, and set contents on a monitor screen. Have.
The digital multifunction peripheral 10 has a copier function, an image scanner function, and a printer function (may have a facsimile transmission / reception function).

  When fulfilling the function of the copying machine, the user stands near the digital multi-function peripheral, operates the operation unit 15 while looking at the display unit 16, makes necessary inputs and settings, and reads a document reading unit (not shown). Set the document on (or set the document on the document feeder). When the user presses a start button provided on the operation unit 15, the image scanner unit 11 reads a document. Then, under the control of the control unit 13, if necessary, the storage unit 14 is involved, and the print unit 12 prints out the image read by the image scanner unit 11.

When the digital multifunction peripheral 10 fulfills the function of a printer, the necessary device drivers (printer drivers) are incorporated in the personal computers 31, 32, 33, 34,... Recognize as a printer. When the personal computer side (for example, the personal computer 31) issues a print command to the digital multi-function peripheral 10, the digital multi-function peripheral 10 receives the instruction via the in-house LAN. The control unit 13 of the digital multi-function peripheral 10 executes print output based on the information to the print unit 12 in accordance with the command.
Here, the device driver is software (computer program) installed in the personal computer so that the personal computer recognizes the digital multifunction peripheral 10 as a device connected to the personal computer.

As a minimum configuration for the digital multifunction device 10 to function as an image scanner, in addition to the digital multifunction device 10, after the scanned image is converted into an electronic file, a folder (the electronic file of the electronic file) is to be stored. Storage location). The user stands by the digital multifunction peripheral 10 and operates the operation unit 15 while viewing the display unit 16 to perform necessary input and setting, specify a file storage location, and read the document reading unit (see FIG. A document is set on (not shown) (or a document is set on a document feeder). When the user presses a start button provided on the operation unit 15, the image scanner unit 11 reads a document. Then, under the control of the control unit 13, the storage unit 14 is involved if necessary, and the control unit 13 converts the image read by the image scanner unit 11 into a file and designates the specified storage location (for example, a file server). 20 folders, or a folder inside any personal computer).
At this time, the digital multi-function peripheral 10 and the file server 20 or a device that stores the scanned image file must be accessible to each other.

≪Where to add software to protect personal information≫
If the personal information is not protected, the configuration described so far is sufficient. However, in order to implement the scanner system of the present invention, a computer program 50 (see FIG. 2) is added to create a mask pattern (create a mask pattern). Processing) and necessary processing for superimposing and outputting the mask.
This computer program 50 can be incorporated entirely as firmware of the digital multi-function peripheral 10 in the hardware configuration of FIG. In that case, the storage unit 14 stores the computer program 50, and the control unit 13 reads and executes the program as necessary. An operator (user) operates the operation unit 15 while looking at the display unit 16 to execute creation of a mask pattern, overlay processing on a scanned image, output processing, and the like. In this case, PC1 to PCn (31 to 39) function as file output destinations (storage locations).
The computer program 50 can also be incorporated as an application program on the PC1 to PCn (31 to 39) side in the hardware configuration of FIG. In that case, indispensable firmware for the image scanning unit 11 to operate as a peripheral device of the personal computer is incorporated on the digital multifunction device 10 side, and the digital multifunction device 10 functions as a scanner connected to the personal computer. To do.
As an intermediate between these two poles, it is conceivable that a part of the computer program 50 is configured as firmware of the digital multi-function peripheral 10 and the rest is installed as application software on the personal computer side. In any case, the functions of the computer program 50 may be realized by cooperation between the digital multifunction peripheral side and the personal computer side.
Further, the computer program 50 may be installed as firmware of the digital multifunction peripheral and an application program on the personal computer side, and all functions may be installed on both sides, and the functions may be shared as necessary to perform a cooperative operation.
Hereinafter, the functions of the computer program 50 will be described on the assumption that all functions are installed in both the digital multifunction peripheral 10 and the personal computer.

FIG. 2 is a diagram schematically showing a software configuration of the scanner system according to the first embodiment shown in FIG.
In FIG. 2, an image reading unit 40 constituting a computer program is a part having a function of converting an electrical signal from the image scanning unit 11 into image data.
The image recognition unit 41 is a part that performs pattern recognition on image data and extracts characteristic figures.
The image analysis unit 42 is a part that executes a process of obtaining a result of pattern recognition and finding a corresponding point corresponding to the reference point. Here, the reference point is a point having a graphic feature of a mask pattern to be described later, and the reference point (1 or 2 or more) is coordinate-adjusted so as to overlap with the corresponding point in the read image (described later). Used for.
The coordinate adjustment unit 43 performs coordinate conversion processing including enlargement / reduction processing so that the corresponding point (1 or 2 or more) on the read image corresponding to the reference point (1 or 2 or more) of the mask pattern overlaps. It is a part to do.

The mask pattern creation unit 44 constituting the computer program 50 is a part including a function for creating a mask pattern for protecting personal information, that is, a function similar to CAD and drawing creation software. The user uses the mask pattern creation unit 44 to generate a necessary mask pattern. That is, the mask pattern creation unit 44 is software that supports a user's work of creating a mask pattern.
The mask pattern management unit 45 manages the mask pattern created by the mask pattern creation unit 44 in association with a document to be protected, a storage location after protection, and the like.
In FIG. 2, the secure management unit 46 manages the protection level of the masked result. For example, a level that does not include personal information at all, a level that includes some personal information but does not connect with other information by itself, a level that does not cause a leak, a level that is not desirable to leak, and a leak that requires damage compensation It is conceivable to separately manage levels such as levels that may occur. In addition to the high and low levels, when the range that can be disclosed differs depending on the party that discloses the information, it is also possible to manage whether or not appropriate information is disclosed to the other party. For example, among items described in the medical chart, items that can be disclosed differ depending on the disclosed parties such as doctors, nurses, pharmacists, and medical office workers.

In FIG. 2, the display unit 47 outputs an image to be displayed on the monitor screen. For example, an image is generated for the purpose of showing the preview image to the user and confirming whether or not this is acceptable immediately before outputting the file.
In FIG. 2, the image superimposing unit 48 performs image superimposition processing such as superimposition of a mask pattern and a personal information scan processing image (superimposition of a plurality of layers when layers described later are used). .
In FIG. 2, an image output unit 49 outputs a mask pattern after generating a mask pattern, an image of a personal information document in which the mask patterns are superimposed, and the like as a file.

  Here, the XX section can be said to be a part of the computer program 50. If attention is paid to the state in which the computer CPU reads and implements a necessary program each time, each XX section is It is also part of the device realized by hardware resources. Therefore, the XX part is a component of the invention of the object.

In FIG. 2, the scan result DB 51 stores, as an image file, scan results that do not require personal information protection. For items that require personal information protection, only information such as the time of scanning may be stored.
The mask template DB 52 stores several templates so that variations such as making a portion to be masked into a rectangle, a parallelogram, and an ellipse can be expanded.
The mask pattern DB 53 stores a pattern (mask pattern) to be superimposed on the entire document to be scanned in order to protect personal information.
The design DB 54 stores various designs (shading, heart design, etc.) for the case of using other designs for the reason that black painting of a mask portion made of a rectangle or the like leads to waste of ink.
The character string DB 55 stores various character strings such as “personal information”, “information” for displaying some character string to clearly indicate that there is personal information in the masked part and that it is protected. Character strings such as “privacy” and “data protection” are stored (see FIG. 8).
When using a layer, the layer management DB 56 stores the relationship between the mask pattern to be used and the layer output that constitutes the mask pattern.
The secure level DB uses each mask pattern to store information about how secure the scan output file that protects personal information is, and whether the mask is appropriate for the information disclosure partner. To do.
The output result DB stores the output result of the protected image that protects the personal information.

These DB groups are stored in a folder in the file server 20 or stored in a storage device such as the storage unit 14 in the digital multifunction peripheral 10. This is because a mask pattern or the like can be used when the digital multifunction peripheral 10 scans a document that requires personal information protection.
Further, it is desirable that the above-described DB group is accessible from the personal computer that performs the work, and the mask pattern creation by the mask pattern creation unit 41 is executed by any one of the plurality of personal computers. When creating mask patterns on two or more computers, do not (cannot) work (write files) at the same time.

<< Operation of Scanner System of Embodiment 1 >>
An overview of the overall operation of the system according to the first embodiment will be described in three parts. First, as a preparation for generating a mask pattern, a process for scanning a form of a document, a second, a process for generating a mask pattern based on scanned data of the form, and a third, filled in based on the form This is a process for scanning a scanned document and outputting a file on which mask patterns are superimposed.

[In the case of questionnaire survey]
A specific explanation will be given by taking the questionnaire shown in FIG. 3 as an example.
Questionnaires may be conducted for people who participated in various events. FIG. 3 shows an example of such a questionnaire form. This form includes personal information such as name, gender, age, address, phone number, and email address. Therefore, it is information that cannot be leaked to the outside as it is.
However, as long as you hide your personal information such as name, address, phone number, and e-mail address, it is a material that can be sent to the outside, and is valuable as a material for creating statistical materials.
Therefore, this scanner system is used.

First, as a preparation for generating a mask pattern, a process of scanning a document form is executed. FIG. 4 is a flowchart schematically showing the flow of processing for scanning a form that does not include personal information (or a form that includes dummy information) as preparation for creating a mask image that protects (hides) personal information.
First, the setting contents such as the resolution, monochrome or color, and the storage location of the output file are acquired (step 401). Then, image scanning is executed on the questionnaire form (one that has not been filled in or one in which dummy information has been entered) (step 402). Based on the electrical signal obtained by image scanning, the image reading unit 40 in FIG. 2 converts the image data into image data that can be handled by the computer. Thereafter, preferably, pattern recognition is performed by the image recognition unit 41 (step 403), and characteristic points A, B, C, D, E, and F (see FIG. 3) are selected by the image analysis unit 42 (step 404). ). These characteristic points are extracted for the purpose of assisting the user in selecting one or more reference points for mask pattern generation. If the user can select one or more points as reference points, this pattern recognition may be omitted.

Second, a process for generating a mask pattern based on data obtained by scanning the form is executed. The mask pattern is information indicating where one or two or more reference points are, and information specifying an area (mask area) in which personal information is to be hidden (for example, the coordinate information of the vertex assuming that the mask area is a rectangle). It is information with.
FIG. 5 is a flowchart schematically showing the flow of processing for creating a mask image.
First, in order to determine one or more reference points, the mask pattern creation unit 44 displays the points A, B, C, D, E, and F shown in FIG. 3 as candidates on the form image. The user (operator) is prompted to select a necessary number of points from them (step 501). When the user selects a necessary number of points (for example, A and E) in response to this, the mask pattern creation unit 44 determines the coordinates of the two reference points as part of the information constituting the mask pattern ( Step 502). At this time, the user may reject all the points indicated as candidates and newly select the necessary number of reference points.
Next, in order to determine the mask area, the user places the mouse pointer in the upper left part of the name input field and drags it toward the lower right to identify the rectangle and create a mask (mask area) (Step 503). Then, a symbol (or character string) to be displayed instead of the personal information is set in the mask area (step 504). This pattern / character string is, for example, the shaded pattern shown in FIG. 6, white, “personal information”, “personal information protection”, “protecting personal information”, “information privacy”, “data privacy” "Data protection" etc. can be prepared and selected from them. You can choose options such as making it a white rectangle, shading, or pasting the text of “data protect” for reasons such as avoiding the use of black ink when printing. When no symbol or character string is selected, the rectangle may be black by default.
After setting the name field in the mask area and setting the symbol / character string, the mask pattern creating unit 44 asks the user whether the mask area is set sufficiently (step 505). Here, in addition to the name field, the address input field corresponds to personal information, so the user answers “NO”. Accordingly, the process proceeds to step 503 and step 504. In other words, the user specifies a rectangle by dragging the mouse so as to cover the address entry field. In addition, a design, a character string, and the like to be pasted on the mask area are selected.
When these pieces of information are input, the user selects YES in step 505, saves the reference point information and the mask information (step 506), completes the mask pattern, and completes the mask creation process.

Third, a process for scanning a document filled in based on the form and outputting a file in which mask patterns are superimposed is executed. FIG. 7 is a flowchart schematically showing a flow of processing for scanning a document including personal information.
The mask pattern to be applied is read (step 701), and information on one or more reference points is acquired, and then the image reading unit 40 executes an image scanning process of the personal information document (step 702). Subsequently, the image recognition unit 41 performs pattern recognition on the image data and extracts image features (step 703). The image analysis unit 42 finds corresponding points corresponding to one or more reference points of the mask pattern (step 704). The coordinate adjustment unit 43 performs coordinate conversion of the read image so that the corresponding point overlaps the reference point (step 705). As this coordinate conversion, enlargement / reduction, parallel movement, rotational movement, and the like can be considered. In general, even if the questionnaire form is the same form, the scale may be slightly different depending on the printing time and the printing company. In addition, when secondary copy, tertiary copy, fourth copy, or the like is used, there may be a case where a copy machine's habit overlaps to amplify misalignment or distortion. Therefore, by this coordinate conversion process, various shifts and distortions are corrected, and personal information is appropriately protected (hidden) by the mask area defined by the mask pattern.
In addition, even if the number of one or two or more points is one or two, it has been empirically known that appropriate coordinate transformation is possible.
In this way, the mask pattern is superimposed by the image overlay unit 48 on the read image that has been coordinate-adjusted by the coordinate conversion process (step 706). The overlapped state is displayed on the monitor screen by the display unit 47 and can be confirmed visually by the user (see FIG. 8). The image on which the mask information is superimposed and the personal information is hidden is output as an electronic file by the image output unit 49 (step 707). Note that the visual confirmation operation may be omitted (for example, if the “Omit this confirmation from next time” box in FIG. 8 is checked, this confirmation screen will not be displayed next time). For example, when several tens of scanning processes are performed, after confirming the first one, the confirmation operation may be omitted and continuous scanning may be performed.

  When a document containing personal information has information on both sides, and the document feeder supports continuous scanning on both sides, the scanner system for protecting personal information according to the present invention is used. Even in such a case, the above-described processing of image reading, image recognition, image analysis, coordinate adjustment, image superimposition, and image output is continuously executed while performing double-sided continuous scanning for each sheet correspondingly. Is possible. If the processing capacity of the CPU and the size of the memory are sufficient, these processes can be executed in accordance with the speed of the document feeder. Further, if necessary, two or more CPUs may be provided to perform a linked operation.

[In the case of medical charts]
Multiple mask patterns may be required for one document. For example, in the medical chart, the disclosed contents are different for doctors, nurses, pharmacists, and medical clerk. The medical clerk only needs to know the information necessary for medical insurance and long-term care insurance, and does not need to touch other sensitive information. In particular, it is preferable to avoid that a person working in the medical office accidentally touches an acquaintance patient with information on the patient's disease name and medical history.
Therefore, it is useful to manage mask patterns by layers.

The mask pattern in the case of a medical chart will be described as having a plurality of layers.
Layers are often used in CAD (computer-aided drafting or computer-aided design), and there are multiple layers (for example, 16 layers 0 to 15) in one file. By superimposing them, a single drawing is obtained (see FIG. 9). For example, in an architectural cad, elements such as structures, text, dimension lines, dimensions, etc. are written on different layers, so that the elements such as line color and thickness are grouped together. It becomes possible to change.

FIG. 9 is a conceptual diagram showing a state in which a plurality of layers (layer 0 to layer 15) constituting the mask pattern file are superimposed. Here, layer 0 is a layer in which, for example, a medical chart form is read, and only an entry field is provided, and information to be entered is not entered. A mask made of a black rectangle or the like is input to layers 12, 13, 14, and 15. In the layer 15, one black rectangle and three lines are input, and the remaining portion is white (transparent).
Of the sixteen, only one layer is turned on, and the other layers are turned off, so that only one of the layers is used to mask the document.

FIG. 10 is a diagram showing an example of the layer management screen in that case. In the example shown in FIG. 10, for layer 0 to layer 15, items for screen display on / off, overlay output on / off, and designation of output destination are provided, and a preview screen frame is further provided. An image in which all layers whose screen display is turned on is superimposed is displayed in the frame.
In FIG. 10, on / off of the screen display is such that the layer that is displayed on the preview screen is on and the layer that is not displayed is off. On / off of the superimposition output column is an indication as to which layer is overlaid when a document whose personal information is to be protected is scanned. In the output destination column, where to output the image file in which the layer is superimposed on the document scanned when the layer is turned on is entered. For example, the output destination of the superimposed image with the output destination layer 15 turned on is PC1. Here, a doctor A, a doctor B, a nurse, a pharmacist, and a medical clerk are waiting for each of the PC1, PC2, PC3, PC4, and PC5, and the sent file is processed.
In the preview column of FIG. 10, a state in which layer 0 and layer 15 are overlapped is displayed. In the display screen, a blackened portion is a portion masked to protect personal information.

≪Process flow for creating mask pattern with layer structure≫
Here, the process of creating a mask pattern having a layer structure is performed on the PC 1 by a user (for example, a manager in the medical chart) performing a mask pattern creation process, and a program for supporting the process is executed on the PC 1. This will be described as a flow of processing of application software.
When this application software is activated and newly created, the layer 0 is first selected. Then, the form image is read into the layer (layer 0). This form image is an image that is scanned and stored as a file in the form scanning process. Assume that the stored location, for example, a folder in a file server, or a plurality of PCs can be accessed from the PC 1.
After the form image is read into layer 0, layer 1 is selected. Then, the mask 1 is created using the image creation support function of this mask creation process. Specifically, after selecting a figure such as a rectangle, a rectangle with rounded corners or an ellipse, an area to be protected is selected with the mouse. If necessary, a character string to be displayed in the area, for example, “personal information”, “data protection” or the like is selected and associated with the area to be protected (see FIG. 6).
When creating the mask pattern 1, information on which PC stores (or transmits) an image in which the mask information is superimposed and personal information is protected (information of “output destination” in the layer management screen of FIG. 10) ) Is stored in association with the layer.

When the creation of the mask pattern 1 is completed, the layer is then changed to, for example, layer 2. Then, another mask pattern is created for the layer. The explanation is based on the specific example of the medical chart described above. Since the number of the staff who shares the work with the doctor A, the doctor B, the nurse, the pharmacist, and the medical clerk is five, the number of mask patterns is five. is there. Therefore, five mask patterns are created using five layers. Until the number of created mask patterns is sufficient, the layer change and mask pattern creation processes are repeated to increase the number of mask patterns.
Here, whether or not the number of mask patterns has become sufficient is determined by whether the number of mask patterns created (number of layers used) has reached that number by allowing the user to input the required number in advance. It can be judged on the computer side. Alternatively, the user may be prompted to make a determination every time one mask pattern is created.

When the work of creating a plurality of mask patterns using a plurality of layers is completed, the layer information and the mask pattern created so far are stored and finished. In this manner, screen display on / off for each layer, on / off of superposition output, and layer management information having output destination information are stored together with image information of the mask pattern created on each layer.
In addition, the preview screen shown in FIG. 10 is confirmed a plurality of times as necessary during the process of creating a mask pattern by the user.

≪Scanning personal information document when using mask pattern with layer structure≫
In the case of a medical chart, each time one sheet is scanned, when the image recognition, image analysis, and coordinate adjustment processing are performed on the one sheet, five types of mask patterns are overlaid and output as files. Are stored in PC1, PC2, PC3, PC4, and PC5, respectively. Thereby, each of the doctor A, the doctor B, the nurse, the pharmacist, and the medical clerk can access only the information necessary for the doctor A, the doctor B, and the unnecessary medical information. By restricting the authority to access from each PC, secure management can be performed.

[In case of event venue entry sheet]
Suppose an event is held and there are 2,000 visitors. At the entrance of the event venue, each visitor completed the entry sheet at the table near the entrance, submitted it to the reception, and participated in the event. The entry sheet includes items such as the seat number, name, age, gender, telephone number, address, purpose of visit, impressions, advertising media, and goodness at the event.
In the back office that supports the sales department, in order to organize the data (entry contents) of the visitors, 2,000 entry sheets are entered into the database. A plurality of operators (for example, five people) were prepared to perform the work promptly.

It is not preferable to distribute the 2,000 entry sheets to five operators by 400 because each operator contacts personal information.
Therefore, the team leader of this work creates five types of mask patterns (for example, using layers). The mask pattern is preferably created when the entry sheet is prepared. Each of the five types of mask patterns hides about 80% of the entry sheet, and when the portions described in each of the five types are combined, they become the whole.
For each of 2,000 entry sheets, a file is sent so that an image of a scan result in which five types of mask patterns are superimposed is distributed to one operator with one mask pattern.

  Each operator executes database input for the image he / she received. If the database program allows simultaneous input by a plurality of operators, input of the database is completed when the work of five persons is completed. If the database program does not allow simultaneous input by a plurality of operators, the team leader completes the database input by combining the inputs.

This input work can be done after the event, but each time the receptionist receives the entry sheet at the event, each image is scanned one by one and the mask pattern prepared in advance is overlaid. When the operator finishes the reception, the information described in the entry sheet is digitized and can be used.
Therefore, it is possible to use the information in the event, and it is possible to act on the visitors immediately after the event ends.
In addition, even if the transmission to the operator here is performed via the Internet, for example, each piece of data is a mask on about 80% of the personal information. Even if one of them leaks, the level of damage is low.

≪Form scan processing flow≫
The form scan is executed in the same manner as the questionnaire described above.

≪Make mask pattern with file with layer≫
The mask pattern is an electronically stored image of a mask to be overlaid on the entire form, and is used when scanning for personal information protection.
The mask pattern is saved as a file. The mask pattern can be configured as having a plurality of layers as described in the medical chart section.
The processing for forming the mask pattern can also be performed in the same manner as described above.

≪Process to scan documents containing personal information≫
In the case where the entry sheets of the above-mentioned event attendees are made into a database, 2,000 sheets are scanned in order on the manuscript feeder, or every time an entry sheet is submitted at the reception, the scanning process is performed. Each time a mask pattern necessary for the information is overlaid to create a file and send it to a PC used by each operator.

More specifically, in the scanner system, the user is near the digital multi-function peripheral 10 shown in FIG. 1 and operates the operation unit 15 while looking at the display unit 16 so that the control unit 13 needs a program file, A data file is read from the storage unit 14 (if necessary, the file server 20, PC1, PC2,...) And prepared, and then a personal information original (for example, 2) set by a user on an original feeder (not shown). A thousand visitors' entry sheets) are scanned by the image scanner unit 11. Here, the user preferably checks the layer management screen of the read mask pattern file just in case. The layer management screen is the same as the layer management screen at the time of mask creation shown in FIG. If necessary, settings such as changing on / off of each layer and changing the output destination are made.
After that, scanning of personal information documents is started. Even when several documents are set in the document feeder, image scanning, image recognition, image analysis, coordinate adjustment, mask pattern overlay, and storage in the set folder are repeated for the number of mask patterns. And so on until all mask patterns for one document have been processed.

  If the CPU capability of the control unit 13 shown in FIG. 1 and the memory capacity of the storage unit 14 are sufficiently large, the mask overlap output can be obtained in a time commensurate with the time for the image scanner to perform one scanning process. Storage in a folder can be made. If the CPU capacity and the memory capacity are not sufficient, scanning of the next document is started after the processing for one document is completed. Instead of improving the performance of the CPU, the scanning of the image scanner and the overlay of the mask may be shared by using two CPUs.

  If there are five mask patterns, the process ends when all of these processes are completed. When there are a large number of personal information documents, each one of them is processed. According to the example of database entry entry entry, each waiting operator's PC stores image files with personal information protected, and each operator enters the database. It becomes possible.

<< Modified Example of Layer >>
In the above-described embodiment, the number of layers is 16. In this case, up to 15 mask patterns can be created. When two or more layers are used to create one mask pattern, the number of mask patterns that can be created is reduced. By increasing the number of layers to 32 or 64, the number of mask patterns that can be created can be increased.

≪Example not using layers≫
An embodiment that does not use layers is also possible. When layers are not used, a plurality of mask patterns used for each document are managed with different file names. Then, in the process of scanning a document containing personal information, a mask pattern with another file name is called up and overlaid, and the resulting image file is stored or transmitted to a predetermined storage location. In this case, it is conceivable to provide a file for managing the whole (a file having the layer management information shown in FIG. 3) in addition to a file group for storing each mask pattern.

<< Configuration of Scanner System of Second Embodiment >>
FIG. 11 is a block diagram showing a hardware configuration of Embodiment 2 of the present invention (embodiment in which an image scanner is connected to a personal computer via USB). In the first embodiment, the function of the digital multifunction peripheral 10 is used as the image scanner. In the second embodiment, for example, an image scanner 60 connected to the personal computer 31 by USB is used. In FIG. 11, an image scanner 60 without a document feeder is illustrated. However, a scanner with a document feeder is desirable because it increases work efficiency.

<< Operation of Embodiment 2 >>
Since the second embodiment includes the personal computer 31 and the image scanner 60 shown in FIG. 11, the user performs all of the form scan processing shown in FIG. 4, the mask creation processing shown in FIG. 5, and the personal information scan processing shown in FIG. The personal information was protected by superimposing the mask pattern on the image data that had undergone image recognition, image analysis, and coordinate conversion by causing the image scanner 60 to perform image scanning of the document while operating the personal computer 31. An image file can be generated and stored in a required predetermined folder.
In the example shown in FIG. 11, the personal computer 31 is connected to personal computers 32, 33, 34, 35, and 39 via an in-house LAN or the Internet. Stored in a predetermined folder on the PC. An operator standing by in each personal computer can confirm a file stored in a predetermined folder and perform an operation of inputting it into a database.

In FIG. 11, the file server is not drawn, but the personal computer 31 sets a folder in the file server to store the image file obtained by superimposing the five types of mask patterns. An input process may be executed by accessing a folder in the file server.
According to the configuration of the second embodiment, even when a digital multifunction peripheral is not used, an image scan capable of protecting personal information similar to the first embodiment is possible.

<< Configuration of Scanner System of Embodiment 3 >>
FIG. 12 is a block diagram showing a hardware configuration of Embodiment 3 (an embodiment in which an image scanner is connected to a tablet computer through a wireless LAN connection). Here, the wireless LAN can be, for example, a Wi-Fi connection. Since some tablet computers have functions equivalent to those of a personal computer, most or all of the functions of the present system can be installed.

<< Operation of Embodiment 3 >>
By using the tablet computer 80, the person in charge at the site, the team leader of the operator, etc. can change the mask pattern, change the layer, change the output destination, etc. in response to the change in the situation.

The functions that can be installed vary depending on the size of the smartphone memory and the height of the functions.

<< Modified Example of Embodiment 1 >>
In the first embodiment, an example in which the mask creation process of FIG. 5 is performed by a PC (personal computer) has been described. However, the display unit 16 in the digital multifunction peripheral 10 of the first embodiment is sufficiently large, and a touch panel (a keyboard if necessary). 5) may be performed in the digital multi-function peripheral 10 by allowing the input device such as) to sufficiently withstand the graphic creation process. In that case, the user can perform all three processes of the form scan process of FIG. 4, the mask creation process of FIG. 5, and the personal information scan process of FIG. 7 by operating the digital multi-function peripheral 10.

≪Examples of application to various service use forms≫
When a company starts a new service, initially it is flooded with applicants. In this case, the present scanner system can be used for concealing personal information and allowing a plurality of operators to share and input.

≪Examples of application to health questionnaires and questionnaires≫
Similar to the medical charts described above, it can be applied to health surveys and medical questionnaires.

≪Example of application to purchase order≫
It is necessary to hide the ordering source when the order received by the intermediate contractor is directly sent to the manufacturer or wholesaler. This is to prevent manufacturers and wholesalers from working directly with intermediate customers. In this case, the scanner system can be used. By using the manufacturer or wholesaler's server as the storage location for the superimposed image of the scan results, it is possible to complete the document delivery simultaneously with the scan.

<Application example to resume>
In recruitment agencies such as nurses and career change agents, personal information is concealed and human resources are introduced. In this case, the scanner system can be used.

≪Example of application to personnel system≫
The corporate HR system handles personal information about employees. It is desirable to limit the authority to access the information of subordinates by the titles of personnel managers, office managers, general managers, section managers, chiefs, etc. With this system, it is possible to limit access to documents, so it is possible to manage who has access to what items, such as resumes and qualification certificates, at the time of entry. This system may be useful to do so.

≪Use of input agency≫
In the event that an event visitor's electronic entry sheet is outsourced, the company that receives the outsourcing will be able to work more easily by introducing this system. The visitor information is personal information related to sales and is also a trade secret. Therefore, it is possible to receive an order indicating that the level of personal information protection of the input agent is high.

≪Example of application to transmission over the Internet≫
Considering an example in which the environment in which the digital multi-function peripheral is connected to the network as in the first embodiment described above is further expanded and connected to the Internet, the file storage destination of the scanner system is set as a remote server such as a server connected to the Internet. It can also be ground. In that case, scanning with this scanner system can complete the file transmission to a remote location.

≪Application example for facsimile transmission≫
In general, in the digital multi-function peripheral, in addition to the configuration of FIG. 1, a telephone line is also connected to convert an electrical signal (digital signal) read by the image scanning unit 11 into a facsimile transmission signal (analog signal). A (fax modem apparatus) is further provided to function as a facsimile apparatus. Assuming such a digital multi-function peripheral, when this function is combined with this scanner system, when sending a facsimile via a telephone line, a part of the original is masked and personal information is received on the receiving side. One possible application is to send a document that is hidden. In that case, the digital signal obtained by the scanner system device is converted into an analog signal to be placed on the telephone line via the fax modem device. This makes it possible to send a document with a mask to the other party with a single scan, instead of having to print it out, fill it with ink, and send it with a facsimile machine. It becomes.

≪Application example for facsimile reception≫
In the case of a facsimile machine, in addition to the embodiment in which this masking is performed on the transmission side, an embodiment in which this masking is performed on the reception side is also possible. For example, it is possible to construct a mechanism in which the headquarters receives the original application form for various services received from a customer by facsimile and forwards the hidden part of the personal information to the department in charge. In this example, reception from the customer may be performed by facsimile, and transfer to the department in charge may be performed digitally in the form of file storage in a folder on the network. Realizing this without printing on paper leads to significant savings in print paper, ink, toner, and the like.

  The system of the present invention has been described above with specific embodiments, but the present invention is not limited to these. A person skilled in the art can make various changes and improvements to the configuration and function of each server in each of the above embodiments without departing from the scope of the present invention.

  As shown in FIG. 1, the system of the present invention is realized by an OS, application software, a database, a network system, etc. constructed on hardware resources including a computer CPU, memory, auxiliary storage device, display, input device, etc. Since the information processing called image scan processing is specifically realized using the above hardware resources, it corresponds to the technical idea using the laws of nature, It can be used in industries such as information processing and paperwork.
