Description

  The present invention relates to a technique for verifying the validity of information entered in a form using an electronic pen.

  Conventionally, when a person in charge of field work who conducts sales or inspection work at a visiting site reports on paper media reports or slips from the office, there is a limit to the extent to which the company can confirm the validity of the report contents. It was. For this reason, for example, frauds such as counterfeiting receipts in insurance business and false reports in inspection work have occurred.

  In recent years, with the development of IT (Information Technology) technology, digitization of reporting work by mobile phones and mobile PCs has been partially advanced (for example, Patent Documents 1 to 3). For digital data reporting, it is possible to obtain time data at the time of reporting and verify the correctness of the reporting time, but it is not necessarily applicable to all reporting operations due to the peculiarities of industry regulations and reporting requirements. It is not a thing.

  On the other hand, in recent years, pen-type input devices called “electronic pens”, “digital pens” and the like have appeared (hereinafter referred to as “electronic pens” in this specification). “Anoto pen” developed by the company is known. Anotopen is used in a pair with dedicated paper (hereinafter referred to as “dedicated paper”) on which a predetermined dot pattern is printed. In addition to the normal ink-type pen tip, the Anoto pen is equipped with a small camera for reading the dot pattern on the dedicated paper and a data communication unit. When a user writes characters on the special paper with an anotopen or checks an image that is designed on the special paper, the small camera detects the dot pattern on the special paper as the pen moves, and the user Entry data (also referred to as “stroke data”) such as written characters and images is acquired. This entry data is transmitted from the Anotopen to a terminal device such as a nearby personal computer or mobile phone by the data communication unit. Therefore, a system using this anotopen can be used as an input device instead of a keyboard.

  Therefore, it is convenient if the person in charge of field work can obtain the report contents as digital data by filling out a paper medium report or slip by using the above-mentioned electronic pen from the destination.

  Preferred embodiments of the present invention will be described below with reference to the drawings. First, an outline of an electronic pen used as an input device in the system of the present embodiment will be described.

[Electronic pen]
FIG. 1 is a diagram schematically showing how the electronic pen is used, and FIG. 2 is a functional block diagram showing the structure of the electronic pen. As shown in FIG. 1, the electronic pen 10 is used in combination with a dedicated paper 20 on which a dot pattern is printed. The electronic pen 10 includes a pen tip portion 17 similar to a normal ink pen, and a user writes characters on the dedicated paper 20 in the same manner as a normal ink pen.

  As shown in FIG. 2, the electronic pen 10 includes a processor 11, a memory 12, a data communication unit 13, a battery 14, an LED 15, a camera 16, and a pressure sensor 18 therein. The electronic pen 10 includes an ink cartridge (not shown) as a component similar to a normal ink pen.

  The electronic pen 10 does not convert the locus of the ink drawn on the dedicated paper 20 by the pen tip unit 17, but converts the locus coordinates of the movement of the electronic pen 10 on the dedicated paper 20 into data. While the LED 15 illuminates the vicinity of the pen tip 17 on the dedicated paper 20, the camera 16 reads the dot pattern printed on the dedicated paper 20 and converts it into data. That is, the electronic pen 10 can acquire a stroke generated when the user moves the electronic pen 10 on the dedicated paper 20 as image data or vector data.

  The pressure sensor 18 detects the pressure applied to the pen tip portion 17 when the user writes characters on the dedicated paper with the electronic pen 10, that is, the writing pressure, and supplies the detected pressure to the processor 11. The processor 11 switches the LED 15 and the camera 16 on and off based on the writing pressure data given from the pressure sensor 18. That is, when the user writes characters or the like on the dedicated paper 20 with the electronic pen 10, writing pressure is applied to the pen tip portion 17. Therefore, when the writing pressure exceeding the predetermined value is detected, it is determined that the user has started the description, and the LED 15 and the camera 16 are operated.

  The camera 16 reads the dot pattern on the dedicated paper 20 and supplies the pattern data to the processor 11. The processor 11 calculates X and Y coordinates on the dedicated paper 20 from the supplied dot pattern.

  The processor 11 acquires writing pressure array data and X and Y coordinate data while the user's description is performed, and stores them in the memory 12 in association with a time stamp (time information). Therefore, data corresponding to the description content of the user is stored in the memory 12 in time series. The capacity of the memory 12 can be about 1 Mbyte, for example.

  All the acquired data is held in the memory 12 until a transmission instruction is given by the user. When the user issues a transmission instruction, the data communication unit 13 transmits the data in the memory 12 to the terminal device 25 within a predetermined distance from the electronic pen 10. Basically, once a transmission instruction is given, the electronic pen 10 transmits all the data stored in the memory 12 to the terminal device 25, so that the memory 12 is cleared. Therefore, when it is desired to transmit the same information to the terminal device 25 again after transmission, the user needs to write the description on the dedicated paper 20 again. In this case, the user only has to trace characters written on the dedicated paper 20 with an ink pen.

  The electronic pen 10 itself does not include a function button such as a transmission button, and a transmission instruction and other instructions are performed by a user checking the dedicated box provided at a predetermined position on the dedicated paper 20 with the electronic pen 10. Executed. A transmission instruction is associated with the position coordinates of the dedicated box in advance. When the processor 11 receives the position coordinates of the dedicated box, the processor 11 supplies data in the memory 12 to the data communication unit 13 and transmits the data to the terminal device 25. To do. The electronic pen 10 can indicate completion of data transmission by vibration of the electronic pen.

  The battery 14 is for supplying power to each element in the electronic pen 10, and the electronic pen 10 itself can be turned on / off by a cap (not shown) of the electronic pen, for example.

  As described above, the electronic pen 10 has a function of acquiring coordinate data and writing pressure data corresponding to characters and the like described on the dedicated paper 20 by the user and transmitting them to the nearby terminal device 25. Since the pen tip portion 17 is a normal ink pen, the content described on the dedicated paper 20 remains as an original original. That is, at the same time as describing the original paper, its contents can be digitized in the form of coordinate data in real time.

  According to the standard function of the electronic pen 10, data obtained by the electronic pen 10 is in principle in the form of coordinate data or vector data, and is not text data. However, as a standard function, the electronic pen 10 has a function of converting text into alphanumeric characters by describing it in a dedicated area provided on the dedicated paper 20.

  Also, the electronic pen 10 can hold property information (pen information and pen owner information) regarding the pen itself and its owner, and can be referred to from an application. As the pen information, a battery level, a pen ID, a pen manufacturer number, a pen software version, a subscription provider ID, and the like can be held. The pen owner information can hold nationality, language, time zone, email address, free memory capacity, name, address, fax / phone number, mobile phone number, and the like.

  In the data communication unit 13 in the above example, the electronic pen 10 is connected to the terminal device 25 by various methods such as Bluetooth (registered trademark) wireless transmission, wired transmission using a USB cable, and data transmission by contact with a terminal. It is conceivable to perform data transmission.

  Next, a method for acquiring X and Y coordinate data of contents described by the user with the electronic pen will be described. As described above, a predetermined dot pattern is printed on the dedicated paper 20. The camera 16 of the electronic pen 10 does not read the locus of ink described on the dedicated paper 20 by the user, but reads the dot pattern on the dedicated paper 20. Actually, as shown in FIG. 1, the illumination area by the LED 15 and the shooting area of the camera 16 (located in the illumination area) are deviated from the position where the pen tip 17 contacts the dedicated paper 20.

  The dot pattern is printed with a special ink containing carbon, and the camera 16 can recognize only the pattern with the special ink. Even if ruled lines or frames are printed on dedicated paper with inks other than dedicated ink (not including carbon), the electronic pen does not recognize them. Therefore, when creating forms such as various application forms using dedicated paper, input frames, ruled lines, cautions, etc. are printed with ink other than dedicated ink.

  In the dot pattern, as illustrated in FIG. 3, the position of each dot is associated with data. In the example of FIG. 3, the 2-bit information of 0 to 3 is displayed by shifting the dot position vertically and horizontally from the reference position (intersection of vertical and horizontal lines) of the grid. The position coordinates on the dedicated paper are determined by the combination of information expressed in this way. As illustrated in FIG. 4A, 36 dots are arranged in a grid within a range of 2 mm in length and width, and the data array (FIG. 4B) indicated by these dots is displayed on the dedicated paper. Are associated with the position coordinates. Therefore, when the camera 16 of the electronic pen 10 captures a dot pattern as shown in FIG. 4A, the processor 11 changes the data array shown in FIG. 4B based on the dot pattern data input from the camera 16. The position coordinates on the dedicated paper (that is, where the dot pattern is located on the dedicated paper) corresponding to the acquired position are calculated in real time. The minimum unit for recognizing the dot pattern is 2 mm × 2 mm, and the camera 16 takes about 100 shots per second.

  Next, the dedicated paper will be described. An example of the structure of the dedicated paper is shown in FIG. As shown in the figure, the dedicated paper 20 has a dot pattern 32 printed on a mount 30 and a design 34 such as a ruled line printed thereon. The mount 30 is usually paper, and the dot pattern 32 is printed with dedicated ink containing carbon as described above. Further, the design 34 is printed with normal ink or the like. The dot pattern and the design may be printed at the same time, or one of them may be printed first.

  An example of the design 34 is shown in FIG. FIG. 6 shows an example of a certain application form 36 in which a plurality of entry fields 38 and a transmission box 39 are printed. Although it is not clearly shown in FIG. 6 and will be described in detail later, a dot pattern is actually printed on the entire surface of the application form 36, and an entry box 38 and a transmission box 39 are formed on the entire surface using ordinary ink. It is printed. The user can enter the necessary items in each entry field 38 of the application form 36 using the electronic pen 10 in the same manner as a conventional application form without being aware of the dot pattern.

  The area on the dedicated paper 20 can be roughly divided into two types. One is an entry area, in which the content described by the electronic pen 10 is handled as information as it is. In the example of FIG. 6, a plurality of entry fields 38 correspond to this. The other is a functional element, and when the corresponding area is checked with the electronic pen 10, actions, instructions, etc. defined in advance for the area are executed. The transmission box 39 in the example of FIG. 6 corresponds to this.

  The transmission box 39 is used when giving an instruction to transmit data stored in the electronic pen 10 to the nearby terminal device 25 as described above. When the user checks the transmission box 39 with the electronic pen 10, the electronic pen 10 reads the dot pattern in the transmission box. The pattern is associated with a transmission instruction, and the processor 11 in the electronic pen 10 issues a command to transmit data stored in the memory 12 to the data communication unit 13.

  The assignment of dot patterns is usually performed for each application (paper type). In other words, the dot patterns in a certain application form do not overlap in one sheet, but the same dot pattern is printed on the same application form. Therefore, when the user inputs necessary items with the electronic pen 10, it can be specified from the coordinate data on the application form which item of the application form the input item is for.

  As described above, by printing a predetermined design on the dedicated paper on which the dot pattern is printed, various application forms using the dedicated paper can be created. If the user uses the electronic pen 10 and fills in necessary items in a normal manner, the electronic data is automatically acquired.

  In the above example, the dot pattern is printed on the dedicated paper with carbon-containing ink. However, the dot pattern can be printed on ordinary paper using a printer and carbon-containing ink. Furthermore, the design on the dedicated paper can also be formed by a printer instead of printing. When dot patterns are formed on paper by a printer, different dot patterns can be formed on each sheet. Therefore, it is possible to identify and distinguish each of these sheets by the difference in the formed dot patterns.

  In the present specification, the term “printing” has a concept including not only normal printing but also printing by a printer.

  Next, transmission processing of data acquired by the electronic pen will be described with reference to FIG. The data acquired by the electronic pen 10 is mainly data of items input by the user, but usually does not include information on where the service server that is the transmission destination of the data is. Instead, information specifying the application or service related to the dedicated paper is included in the dot pattern on the dedicated paper, and the information is acquired from the dedicated paper during the user's input operation. Therefore, the terminal device 25 that has received the entry data from the electronic pen 10 first makes an inquiry to the inquiry server 26 to which service server 27 the data input to the dedicated paper should be transmitted. The inquiry server 26 has information on a corresponding service server for each dedicated paper, and in response to an inquiry from the terminal device 25, information (such as a URL) of the service server 27 that performs a service related to the dedicated paper. Reply to the terminal device 25. Then, the terminal device 25 transmits the entry data acquired from the electronic pen to the service server 27.

  In the above example, the terminal device 25, the inquiry server 26, and the service server 27 are separately configured. However, some or all of them may be configured as one device. In this embodiment, it is assumed that the verification server described later also serves as the inquiry server 26 and the service server 27.

[Verification system]
Next, the verification system of this embodiment will be described. FIG. 7 shows a schematic configuration of the verification system 100. The verification system 100 shown in FIG. 7 acquires the report content entered in the electronic pen form (hereinafter referred to as “form”) 3 by the user as digital data, and also transmits the digital data to the mobile terminal 28 that transmits the digital data. By acquiring the location information, the validity of the report content can be verified.

  As shown in FIG. 7, the verification system 100 is configured by connecting a mobile terminal 28, a verification server 4, and a GPS server 5 through a network 2. Here, one suitable example of the network 2 is the Internet. The mobile terminal 28 is a terminal device used by a user, and is a terminal capable of exchanging data via the network 2 such as a mobile phone or PDA (Personal Digital Assistants). The mobile terminal 28 is a terminal having a GPS function and a signature function. The GPS function is a function that can acquire location information (latitude / longitude / altitude) of the mobile terminal 28 using a position measurement radio wave transmitted from a satellite orbiting the earth. The signature function is a function for giving an electronic signature using an electronic certificate for client authentication stored in the USIM.

  The verification server 4 is connected to a user database (hereinafter referred to as “DB”) 6, a location DB 7, a verification DB 8, and a form DB 9. The verification server 4 receives digital data of report contents entered in the form 3 from the mobile terminal 28. The server acquires location information of the mobile terminal 28 from the GPS server 5 and verifies the validity of the report contents. The GPS server 5 is a server that calculates location information based on the latitude and longitude from the mobile terminal 28 and transmits the location information to the verification server 4. 7 includes one mobile terminal 28 as a component for convenience, but the present invention is not limited to this, and a plurality of mobile terminals 28 may be included as a component.

  First, the outline of the verification method in this system will be described with reference to FIGS. FIG. 8A shows an example of a form 3 in which a user who has performed a field work enters report contents using the electronic pen 10. FIG. 8B is an example of the form 3 to which item IDs for identifying each item are assigned. FIG. 9 is an example of the form 3 that is actually filled in by the user. In this embodiment, it is assumed that the user performs a predetermined inspection work and enters the inspection contents in an inspection table as shown in FIG.

  The form 3 is created as the above-mentioned dedicated paper, and is composed of a plurality of items as shown in FIG. Specifically, the form 3 includes items of a start box 50, an end box 51, a transmission box 39, inspection boxes 52a to 52d, and a problem location box 53. As shown in FIG. 8B, an item ID for identifying each item such as “K01” and “K02” is assigned to each item.

  The start box 50 is an item for filling in a check mark (letter, etc.) when the user starts filling in the form 3, and the end box 51 is checked when the user finishes filling in the form 3. This is an item for entering a mark (such as a letter). As described above, the transmission box 39 is an item in which a check mark (letter etc.) is entered when an instruction for transmitting the data stored in the electronic pen 10 to the nearby portable terminal 28 is given.

  The inspection boxes 52a to 52d are items in which symbols indicating whether or not there is a problem with the corresponding inspection items are entered. For example, it may be possible to enter a cross (×) when there is a problem with the inspection items and a circle (○) when there is no problem with the inspection items. The problem location box 53 is an item illustrating locations where there are problems as a result of inspection.

  The user fills in the form 3 using the electronic pen 10 as shown in FIG. 9 in order to report the result of the predetermined inspection work. The electronic pen 10 acquires the stroke data corresponding to the entered content, temporarily stores it in the memory in the electronic pen 10, and then transmits the stroke data to the portable terminal 28. The mobile terminal 28 receives the stroke data entered by the user from the electronic pen 10 and transmits it to the verification server 4 through the network 2. The verification server 4 acquires the stroke data as entry information relating to the contents entered in each item on the form 3 by the user. In addition to the stroke data, the entry information includes time information related to the entry time for each item and the pen ID of the electronic pen 10.

  The verification server 4 extracts item entry information entered in each item from the obtained entry information based on a coordinate table described later. Then, the verification server 4 identifies the transmission time, calculates the item entry time, and calculates the form entry time based on the time information included in the item entry information. Here, the transmission time is the time when the content entered in the form 3 by the user is transmitted as digital data to the verification server 4, and the time when the check mark is entered in the transmission box 39. The item entry time is the entry time until a symbol is entered in each check box 52, and can be calculated based on the difference from the entry time in the box entered immediately before. This item entry time can be simulated as the inspection time for each inspection item. On the other hand, the form entry time is the time required for entry in the form 3 and can be calculated based on the difference between the entry time in the start box 50 and the entry time in the end box 51.

  Next, the verification server 4 acquires the location information of the portable terminal 28 at the time of transmitting the entry information from the GPS server 5. Then, the verification server 4 verifies the validity of the report contents of the user by referring to a time table described later based on the acquired location information and the specified transmission time. Here, in the time table, a place and time at which the user is scheduled to perform a predetermined inspection work are set in advance. That is, the verification server 4 can verify whether or not the user has performed the inspection work according to the schedule along the time table based on the acquired location information and the specified transmission time. The verification server 4 verifies the validity of the report contents of the user by referring to a coordinate table described later based on the calculated item entry time and form entry time. Here, in the coordinate table, a form required time required for filling in a form and an item required time required for filling in each item are set in advance. That is, the verification server 4 compares the calculated item entry time and form entry time with the item required time and form required time set in the coordinate table to determine whether the inspection work has been properly performed over time. Can be verified.

  The verification server 4 creates a report content confirmation screen based on the entry information and the format data of the form 3, and transmits the confirmation screen to the mobile terminal 28. If there is no mistake in the content of the confirmation screen, the user activates the electronic certificate and electronic signature application in the portable terminal 28, assigns the electronic signature to the signature information, and uses the verification server via the network 2. 4 to send. The user confirms the report contents by transmitting the signature information. The verification server 4 can further improve the authenticity of the report contents of the user by verifying the signature information acquired from the mobile terminal 28.

[Verification server]
Next, the verification server 4 will be described in detail. FIG. 10 shows an internal configuration of the verification system 100, particularly the verification server 4. As illustrated, the verification server 4 includes a verification program 200, an entry information acquisition function 101, a coordinate table 102, a time table 103, an item entry information extraction function 104, a time information extraction function 105, a location information acquisition function 106, and a verification function 107. , A confirmation screen creation / transmission function 109 and a signature verification function 110. Each function is realized by the CPU included in the verification server 4 executing a program prepared in advance.

  The verification program 200 verifies the validity of the report content based on the digital data of the report content entered in the form 3 by the user using the electronic pen 10 and the location information of the mobile terminal 28 that transmits the digital data. This is a program to be verified. The verification program 200 is a program for creating a report content confirmation screen and verifying the authenticity of the report content based on the user's signature information for the confirmation screen.

  The entry information acquisition function 101 is a function for acquiring entry information entered in the form 3 by the user using the electronic pen 10 by executing the verification program 200. It is assumed that the entry information includes time information regarding the time entered in the form 3 and the pen ID of the electronic pen 10.

  Here, the coordinate table 102 will be described with reference to FIG. FIG. 11 is a diagram schematically illustrating the data structure of the coordinate table 102. As illustrated, the coordinate table 102 includes a form ID, a form required time, an item ID, an item type, an item required time, and coordinate data. The form ID is information for identifying the form 3, and the form required time is a standard of the time required for filling in the form 3. When the form 3 is an inspection table as shown in FIG. 8A, the form required time can be assumed to be the average time required for the inspection work. Therefore, the verification server 4 determines that “there is a suspicion of empty inspection” when the form entry time specified by the time information extraction function 105 described later is extremely shorter than the required time for the form.

  The item ID is information for identifying each item constituting the form 3, and the item type is information indicating the type of each item. The item required time is set only for the item whose item type is “inspection”, and is a standard of the time required to enter a symbol corresponding to each inspection item. When the form 3 is an inspection table as shown in FIG. 8A, the item required time can be assumed to be the average time required for the inspection work corresponding to each inspection item. Therefore, if the item entry time specified by the time information extraction function 105, which will be described later, is extremely short compared to the item required time, the verification server 4 “suspects empty inspection” even if there is no problem in the form entry time. Is determined. For items other than the item type “inspection”, the item required time is not set because there is no close relationship between entry in the item and substantial inspection work. The coordinate data is position information indicating the arrangement of each item on the dot pattern printed on the form 3.

  Here, the time table 103 will be described with reference to FIG. FIG. 12 is a diagram schematically showing the data structure of the time table. As shown in the figure, the time table 103 is set with a location and time at which the user is scheduled to perform inspection work and business, and is composed of a user ID, a visitor ID, and a time. The user ID is information for identifying the user. As shown in FIG. 13, the user DB 6 stores information about the user such as name and affiliation using the user ID as a key. Therefore, by referring to the user DB 6 based on the user ID of the time table 103, it is possible to easily grasp who is scheduled. The visited ID is information for identifying a company or a house to be visited. As shown in FIG. 14, the location DB 7 stores location information regarding the name of the visited location and the latitude and longitude of the visited location using the visited location ID as a key. Therefore, by referring to the location DB 7 based on the visit destination ID of the time table 103, the location information of the visit destination can be easily obtained. The time is a scheduled transmission time at which the entry information is transmitted after the inspection work or business is performed at the corresponding visited site.

  The item entry information extraction function 104 is a function for extracting entry information entered in each item as item entry information by referring to the coordinate data of the coordinate table 102 from the entry information acquired by the entry information acquisition function 101. .

  As shown in FIG. 10, the time information extraction function 105 further includes a transmission time specifying function, an item entry time calculation function, and a form entry time calculation function. The transmission time specifying function is a function for extracting time information from item entry information corresponding to the transmission box 39 and specifying the time when the electronic pen 10 transmits the entry information entered in the form 3 to the verification server 4. The item entry time calculation function is a function for calculating the entry time for each item whose item type is “inspection”. Specifically, the item entry time calculation function calculates the item entry time based on the difference between the entry time of the item entered immediately before and the entry time of the item. The form entry time calculation function is a function for extracting time information from the item entry information corresponding to the start box 50 and the end box 51 and calculating the entry time on the form 3 based on the difference between the entry times.

  The location information acquisition function 106 is a function for acquiring location information of the mobile terminal 28 from the GPS server 5 when the entry information acquisition function 101 acquires entry information by executing the verification program 200. That is, the location information acquisition function 106 acquires information regarding the latitude and longitude of the mobile terminal 28 at the time when the electronic pen 10 transmits the entry information to the verification server 4.

  As shown in FIG. 10, the verification function 107 further includes a time table verification function and a required time verification function. The time table verification function refers to the time table 103 based on the transmission time specified by the time information extraction function 105 and the location information acquired by the location information acquisition function 106, and whether there is a problem in the schedule. To verify. That is, the verification function 107 determines “suspected fraud” when the transmission time is significantly different from the time in the time table 103, and when the location information is significantly different from the location information of the visited site in the time table 103. The time table 103 referred to at this time corresponds to the user who has entered the form 3 with the electronic pen 10. For example, when one electronic pen 10 is assigned to each user, the verification function 107 specifies the user ID based on the pen ID included in the entry information, and the time table based on the user ID. 103 will be referred to.

  The required time verification function verifies whether there is a problem by comparing the form entry time calculated by the time information extraction function 105 with the required form time set in the coordinate table 102. In other words, the verification function 107 determines that there is a suspicion of empty inspection when the form entry time is significantly shorter than the required time for the form. The required time verification function verifies whether there is a problem by comparing the item entry time calculated by the time information extraction function 105 with the required item time set in the coordinate table 102. That is, the verification function 107 determines that there is a suspicion of empty inspection when the item entry time is significantly shorter than the item required time.

  Further, the verification function 107 stores the entry information acquired by the entry information acquisition function 101 and the verification result by the verification function 107 in the verification DB 8 as shown in FIG. FIG. 15 is a diagram schematically illustrating the data structure of the verification DB 8. As shown in FIG. 15, the verification DB 8 includes a user ID, a form ID, a transmission time, location information, a form entry time, an item ID, an item entry time, and a verification flag. The verification flag further includes an item required time, a form required time, and a time table. As illustrated, the verification function 107 stores a user ID, a form ID, a transmission time, location information, a form entry time, an item ID, and an item entry time based on the entry information. Here, for example, when one electronic pen 10 is assigned to each user, the user ID can be specified from the pen ID included in the entry information. The form ID can be specified by referring to the coordinate data of the coordinate table 102 based on the entry information. Further, as illustrated, the verification function 107 stores the results of the time table verification function and the required time verification function as the verification flag item required time, form required time, and time table. As a result, the verification server 4 can easily grasp what kind of fraud may have been performed by which user by referring to the verification DB 8.

  The confirmation screen creation / transmission function 109 further includes a format data extraction function and a writing pressure detection function. The format data extraction function is a function for extracting format data corresponding to the form 3 from the form DB 9. As shown in FIG. 16, the form DB 9 stores form names and format data using form IDs as keys. Therefore, the format data extraction function extracts the corresponding format data from the form DB 9 based on the form ID of the form 3. The writing pressure detection function is a function of detecting the writing pressure of stroke data included in the entry information. Specifically, when the user fills in an arbitrary figure with the electronic pen 10 as in the problem box 53 of FIG. 9, the stroke that is strongly written on the form 3 is confirmed based on the detection result of the writing pressure detection function. Can be displayed in bold or another color on the screen. The confirmation screen creation / transmission function 109 is a function for creating a confirmation screen based on the format data, entry information, and writing pressure detection result, and transmitting the confirmation screen to the mobile terminal 28.

  In the present embodiment, it is described that highlighting (boldness, color change, etc.) is performed using the writing pressure detection function, but the present invention is not limited to this, and the electronic pen 10 is used. It is also possible to perform highlighting on the confirmation screen by, for example, writing a double line below the character string that has been used and entered in the form 3.

  The signature verification function 110 is a function for acquiring and verifying signature information regarding the electronic signature performed on the confirmation screen from the mobile terminal 28. Thereby, if there is no problem in the verification result of the signature information, the authenticity with respect to the report content is further improved.

[Verification process]
Next, verification processing executed by the verification system 100 will be described. FIG. 17 is a flowchart of the verification process.

  The user fills in the form 3 using the electronic pen 10 after performing a predetermined inspection work. When the entry to the form 3 is completed, the user transmits the entry information to the verification server 4 via the portable terminal 28 by entering a check mark in the transmission box 39.

  The verification server 4 acquires entry information from the portable terminal 28 (step S1), and extracts entry information for each item as item entry information based on the coordinate table 102. And the verification server 4 specifies transmission time based on the time information contained in the item entry information corresponding to the transmission box 39 (step S2). Further, the verification server 4 calculates the form entry time based on the time information included in the item entry information corresponding to the start box 50 and the end box 51 (step S3). The verification server 4 calculates the item entry time for each item based on the time information included in each item entry information (step S4). Furthermore, the verification server 4 acquires the location information of the portable terminal 28 from the GPS server 5 (step S5). And the verification server 4 memorize | stores a required matter in verification DB8 based on entry information (step S6).

  Next, the verification server 4 performs verification based on the coordinate table 102 (step S7). First, the verification server 4 determines whether there is a problem by comparing the form required time in the coordinate table 102 with the specified form entry time (step S8). If there is a problem (step S8; Yes), the verification server 4 sets that there is a problem in the verification flag of the form required time in the verification DB 8, and proceeds to step S9 (step S17). On the other hand, when there is no problem (step S8; No), the verification server 4 determines whether there is a problem by comparing the item required time of the coordinate table 102 with the specified item entry time (step S9). ). If there is a problem (step S9; Yes), the verification server 4 sets that there is a problem in the verification flag of the item required time in the verification DB 8, and proceeds to step S11 (step S18).

  On the other hand, when there is no problem (step S9; No), the verification server 4 performs verification based on the time table 103 (step S11). The verification server 4 determines whether there is a problem in the schedule by referring to the time table 103 based on the specified transmission time and the acquired location information (step S12). If there is a problem (step S12; Yes), the verification server 4 sets that there is a problem in the verification flag of the time table in the verification DB 8, and proceeds to step S14 (step S20). On the other hand, when there is no problem (step S12; No), the verification server 4 creates a confirmation screen and transmits it to the portable terminal 28 (step S14).

  The portable terminal 28 displays a confirmation screen through a browser or a dedicated application. If there is no mistake in the confirmation screen, the user activates the electronic certificate and electronic signature application of the portable terminal 28, assigns the electronic signature to the confirmation screen, and transmits it to the verification server 4 as signature information. . As a result, the user confirms the report contents. The verification server 4 acquires signature information from the mobile terminal 28 and verifies it (step S15). Thereby, the authenticity of the report contents by the user is further improved.

  Although not described in the present embodiment, the order in which items are entered in the coordinate table 102 is set in advance, and the presence or absence of unnatural additions is verified based on the order and time information. Is also possible. As a result, for example, it is possible to accurately detect fraud such as when the user falsifies the amount of the receipt after separating from the contractor in business.

  In the present embodiment, the present invention is applied to the inspection work report using the form 3 as shown in FIG. 8A. However, the present invention is not limited to this and is arbitrarily designed. The present invention can be applied to various reports using the generated form 3. Specifically, the present invention can be applied to manufacturing / infrastructure repair / inspection reports, financial business receipts and transaction reports, sales activities in each industry, business negotiation results reports, and the like.

  Further, in this embodiment, as shown in FIG. 12, the visitor ID and time are set in the time table 103, but the present invention is not limited to this, and either the visitor ID or time is set. It is good also as setting. That is, items to be set in the time table 103 can be arbitrarily set.

  According to the present embodiment, the electronic pen 10, the form 3, the portable terminal 28 equipped with the GPS function, and the GPS server 5 are linked, thereby validating the report of field work such as sales and inspection work performed at the visited site. The company can easily verify it. In other words, it is possible to improve the accuracy of reporting validity confirmation on the company side. Specifically, according to the present embodiment, the company can not only instantly acquire the digital data of the report contents, but also detect the presence or absence of falsification or additional writing by analyzing time information and location information. .

  Further, according to the present embodiment, the report is made by filling in the paper medium form 3 using the electronic pen 10 instead of using the keyboard and the mouse. According to this, since an arbitrary figure can be entered freely, non-standard information can be easily transmitted as compared with a PC, a PDA, or the like. Furthermore, since highlighting can be performed based on the user's writing pressure, the user can easily and clearly report sales and inspection work without memorizing complicated operations.

  Furthermore, according to the present embodiment, the user can give an electronic signature to the report content confirmation screen using the client authentication electronic certificate of the mobile terminal 28. Therefore, the authenticity of the report content can be further improved.

  As described above, the validity of the report content can be verified by acquiring and analyzing the digital data of the report content entered by the electronic pen and the location information of the mobile terminal that transmits the digital data.
