Description

  The present invention relates to a technique for preventing an unauthorized third party from using an electronic pen form.

  In recent years, pen-type input devices called “electronic pens” and “digital pens” have appeared (hereinafter referred to as “electronic pens” in this specification). The developed “Anoto pen” is known. Anotopen is used in a pair with dedicated paper (hereinafter also 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 information such as written characters and images is acquired. This entry information is transmitted from the Anotopen by the data communication unit to a terminal device such as a nearby personal computer or mobile phone. The system using this anotopen can be used as an input device in place of the keyboard, and is very easy to use for users who are reluctant to use the personal computer and keyboard described above. Therefore, as a technique for digitizing data entered in various business documents, application forms, contracts, etc., a system using an electronic pen is becoming widespread (for example, Patent Document 1).

  With the spread of systems using electronic pens in this way, for example, when registering entry information written on dedicated paper with electronic pens, processing by humans other than outsiders and authorized personnel is prevented. A system is needed. In other words, if there is a system that prevents unauthorized use by a third party, the electronic pen can be used more safely in terms of security.

  ADVANTAGE OF THE INVENTION According to this invention, when processing the entry information entered in the electronic pen form, processing by an unauthorized third party can be prevented.

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 transmission instruction and other instructions are executed when the user checks the dedicated box provided at a predetermined position on the dedicated paper 20 with the electronic pen 10. 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. Further, the electronic pen 10 itself may be equipped with a transmission function.

  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 acquires coordinate data (also referred to as “coordinate information”) and writing pressure data corresponding to characters described on the dedicated paper 20 by the user, and transmits the acquired data to the nearby terminal device 25. Although it has a function, since the pen tip portion 17 of the electronic pen 10 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 portion 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 generated. 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 information 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 information 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. The server described later in this embodiment also serves as the inquiry server 26 and the service server 27.

[Processing system]
Next, the processing system of this embodiment will be described. FIG. 7 shows a schematic configuration of the processing system. An object of the processing system shown in FIG. 7 is to provide a processing system that prevents processing by an unauthorized third party when processing the entry information entered in the electronic pen form 3 by the electronic pen 10.

  As shown in FIG. 7, the processing system is configured by connecting the terminal device 25 and the server 5 through the network 2. Here, one suitable example of the network 2 is the Internet.

  The terminal device 25 is a terminal device capable of transmitting and receiving data via a network such as a personal computer (hereinafter referred to as “PC”) or a mobile phone used by a user. The entry content entered in the electronic pen form 3 by the electronic pen 10 is transmitted as entry information to the server 5 via the terminal device 25. The entry information includes information about strokes and coordinates relating to entry contents entered by the user. Here, the electronic pen form 3 is the above-described dedicated paper that the electronic pen 10 can recognize.

The server 5 acquires entry information corresponding to the contents entered in the electronic pen form 3 by the electronic pen 10, and determines whether the entry information is information entered by an unauthorized third party. Specifically, the authorized user uses the electronic pen 10 to enter a check mark in the hidden item (hidden entry area) of the electronic pen form 3 or the password entry item (password ) of the electronic pen form 3 Specify the password in the ( Entry area) . Therefore, although details will be described later, the server 5 determines whether or not the entry information is based on the entry information by determining whether or not a check mark is entered in the hidden item and whether or not the password specified in the password entry is successful. It is determined whether the data is legitimate data by legitimate users or fraudulent data by an unauthorized third party.

  The server 5 is connected to an unauthorized registration database (hereinafter referred to as “DB”) 6.

  According to this, based on the coordinate information and time information included in the entry information, the server 5 determines whether the entry information is regular data by a legitimate user or unauthorized data by an unauthorized third party. can do. Therefore, for example, when the entry information entered in the electronic pen form 3 by the electronic pen 10 is registered, it is possible to prevent processing by a person other than an outsider or a regular person.

[First embodiment]
First, a first embodiment in the processing system of this embodiment will be described. In the first embodiment, when an authorized user fills in the electronic pen form 3a with the electronic pen 10, he or she enters a check mark in a hidden item provided on the electronic pen form 3a. It is instructed only by a legitimate user in advance to put a check mark on the hidden item, and the hidden item is placed at a position where it is difficult to visually recognize. It is difficult to enter a check mark in a hidden item when filling in the electronic pen form 3a. That is, it is almost impossible for a third party who does not know the presence of a hidden item or a check for the hidden item to enter a check mark in the hidden item when filling in the electronic pen form 3a.

  Therefore, the server 5a determines whether or not a check mark is entered in the hidden item based on the entry information. When the check mark is entered, the server 5a authenticates that the entry information is regular data, and executes predetermined data processing based on the entry information. On the other hand, if no check mark is entered, it is determined that the entry information is unauthorized data, and the entry information is separately registered in the unauthorized registration DB 6 as unauthorized entry information. Thereby, the server 5a can prevent the process based on the entry information by an unauthorized third party.

(I) Electronic Pen Form Here, the electronic pen form 3a used in the processing system of the first embodiment will be described with reference to FIG. FIG. 8 shows an example of the electronic pen form 3a.

  As shown in FIG. 8A, the electronic pen form 3a includes a plurality of items such as a name item for entering a name and an address item for entering an address. Further, the electronic pen form 3a has a hidden item 50 that cannot be easily recognized by the user in addition to the name item and address item that can be easily recognized by the user. In the present embodiment, the hidden item 50 is arranged in a logo mark portion printed on the electronic pen form 3. The hidden item 50 is a user area indicating the validity and validity of the data, has no ruled line, and the user cannot easily recognize the presence of the hidden item 50. The fact that the hidden item 50 is arranged in the logo mark portion is not disclosed to non-authorized users.

  In FIG. 8, for the sake of convenience, in order to explain the hidden item 50, a broken line is shown, but there is actually no broken line. Therefore, if it is not disclosed in advance, it is almost impossible for the user to recognize the hidden item 50.

  As shown in FIG. 8B, a legitimate user always writes a check mark in the hidden item 50 when he / she fills in the name item and address item using the electronic pen 10. Finally, by filling a check mark in the transmission box 39, the entry information corresponding to the contents entered in the electronic pen form 3a is transmitted to the server 5a via the terminal device 25.

  The server 5a determines whether the information entered in the hidden item 50 can be extracted from the entry information based on the definition information described later, so that the entry information is valid data or illegal data. Determine whether. That is, the server 5a determines whether or not the entry information is valid data or illegal data by determining whether or not a check mark is entered in the hidden item 50.

In the present embodiment, as shown in FIG. 8, the hidden item 50 is arranged in the logo mark portion, but the present invention is not limited to this. For example, it may be arranged in a state that is not visually recognizable (not visually displayed) in a completely different place from a logo mark or the like, and for another electronic pen associated with the electronic pen form 3a. It may be arranged in a form. In the present embodiment, as shown in FIG. 8, there is one hidden item arranged in one electronic pen form 3a. However, the present invention is not limited to this, and one A plurality of hidden items may be arranged on the electronic pen form. That is, the design of the electronic pen form 3a can be arbitrarily set, including the location of the hidden item.

(Ii) Server Next, the server 5a in the first embodiment will be described in detail. FIG. 9 shows an internal configuration of the server 5a in the processing system 100 of the first embodiment. As illustrated, the server 5 a includes an authentication program 101, entry information acquisition function 102, definition information 103, authentication entry information determination function 104, authentication function 105, and data processing execution function 106. In addition, each function is implement | achieved when the CPU which the server 5a has runs the program prepared beforehand.

  The authentication program 101 determines whether or not the hidden item 50 has been filled in with the electronic pen 10 based on the written information. It is a program that executes processing. In addition, when the information is not filled in, it is a program that determines that the written information is illegal data and registers it as illegal written information.

  The entry information acquisition function 102 is a function for acquiring entry information corresponding to the contents entered in the electronic pen form 3 from the electronic pen 10.

  The authentication entry information determination function 104 refers to the definition information 103 and determines whether the authentication entry information corresponding to the content entered in the hidden item 50 can be extracted from the entry information acquired by the entry information acquisition function 102. It is a function. When the user enters a check mark in the hidden item 50 with the electronic pen 10, the authentication entry information determination function 104 can extract the authentication entry information from the entry information. However, when the user does not enter anything in the hidden item 50 with the electronic pen 10, the authentication entry information determination function 104 cannot extract the authentication entry information from the entry information. Therefore, it is possible to determine whether or not a check mark or the like is entered in the hidden item 50 by determining whether or not the authentication entry information can be extracted from the entry information.

  Here, the definition information 103 will be described in detail with reference to FIG. FIG. 10 is a diagram schematically illustrating the data structure of the definition information. As illustrated, the definition information 103 includes an item ID, an item name, and coordinate information. The item ID is information for identifying each item constituting the electronic pen form 3. The item name is the name of each item, for example, “hidden item”, “name item”, “address item”, and the like. The coordinate information is position coordinates indicating the arrangement of each item on the dot pattern. In this embodiment, the arrangement of each item, which is a quadrangle, on the dot pattern is indicated by the upper left vertex coordinate and the lower right vertex coordinate of each item. The authentication entry information determination function 104 corresponds to the contents entered in the hidden item 50 in the entry information by referring to the coordinate information in the definition information as shown on the basis of the coordinate information included in the entry information. It can be determined whether authentication entry information is included.

  When the authentication entry information determination function 104 determines that the authentication entry information can be extracted from the entry information, the authentication function 105 authenticates that the entry information acquired by the entry information acquisition function 102 is authorized data by an authorized user. It is a function to do. Further, the authentication function 105, when the authentication entry information determination function 104 determines that the authentication entry information cannot be extracted from the entry information, the entry information acquired by the entry information acquisition function 102 is illegal data by an unauthorized third party. It is a function that determines that there is. The entry information determined to be unauthorized data is registered in the unauthorized registration DB 6 as unauthorized entry information.

  The data processing execution function 106 is a function that executes predetermined data processing based on the entry information that is authenticated as normal data by the authentication function 105.

(Iii) Authentication process Next, the authentication process executed by the processing system 100 of the first embodiment will be described. FIG. 11 is a flowchart of the authentication process in the first embodiment.

  Information regarding the hidden item 50 is disclosed in advance to the authorized user.

  The user uses the electronic pen 10 to enter necessary information in the electronic pen form 3a. At this time, the authorized user enters a check mark in the hidden item 50. In response to the user's instruction, the electronic pen 10 transmits entry information corresponding to the contents entered in the electronic pen form 3a to the server 5a.

  The server 5a has in advance definition information that defines the items constituting the electronic pen form and the coordinate information indicating the position coordinates of the corresponding items on the dot pattern in association with each other. Further, the server 5a acquires entry information from the electronic pen 10 via the terminal device 25 (step S1). Then, the server 5a extracts the authentication entry information entered in the hidden item 50 from the entry information by referring to the definition information (step S2). When the authentication entry information can be extracted from the entry information (step S3; Yes), the server 5a authenticates the entry information as regular data (step S4). Further, the server 5a executes predetermined data processing based on the entry information that has been authenticated as regular data (step S5), and completes the authentication processing. On the other hand, when the authentication entry information cannot be extracted from the entry information (step S3; No), the server 5a determines that the entry information is illegal data (step S6). Further, the server 5a registers the entry information determined to be unauthorized data in the unauthorized registration DB 6 (step S7). That is, the data processing based on the entry information determined to be unauthorized data is not executed, and the authentication processing ends.

  In the present embodiment, the entry information determined to be unauthorized data is registered in the unauthorized registration DB 6, but the present invention is not limited to this and is used for predetermined data processing. It is good also as deleting.

As described above, according to the present embodiment , the electronic pen form 3 is provided with “hidden items” in a form that only a regular user can understand. Therefore, when a check mark is entered in the hidden item 50, the server 5a authenticates that the entry information is regular data, and executes predetermined data processing based on the entry information. On the other hand, if no check mark is entered, it is determined that the entry information is unauthorized data, and the entry information is separately registered in the unauthorized registration DB 6 as unauthorized entry information. Thereby, the server 5a can prevent the process based on the entry information by an unauthorized third party.

[Second Embodiment]
Next, a second embodiment will be described in the processing system of the present embodiment. In the second embodiment, when an authorized user fills in the electronic pen form 3b with the electronic pen 10, by filling a check mark in the password entry item provided on the electronic pen form 3b, Specify a password. Since the password is specified and the correct password is disclosed only to authorized users in advance, when an unauthorized third party fills in the electronic pen form 3b with the electronic pen 10, the correct password is entered in the password entry item. It is difficult to specify. That is, it is almost impossible for a third party who does not know the correct password to specify the correct password in the password entry item when filling in the electronic pen form 3b.

  Therefore, the server 5b determines whether or not a correct password is designated by entering a check mark in the password entry item based on the entry information. When the correct password is designated, the server 5b authenticates that the entry information is regular data, and executes predetermined data processing based on the entry information. On the other hand, if the correct password is not specified, it is determined that the entry information is unauthorized data, and the entry information is separately registered in the unauthorized registration DB 6 as the unauthorized entry information. Thereby, the server 5b can prevent the process based on the entry information by an unauthorized third party.

(I) Electronic Pen Form Here, the electronic pen form 3b used in the processing system of the second embodiment will be described with reference to FIG. FIG. 12 is an example of the electronic pen form 3b.

  As shown in FIG. 12A, the electronic pen form 3b includes a plurality of items such as a name item for entering a name and an address item for entering an address. Further, the electronic pen form 3b has a password entry item 60 in which a password can be designated by entering a check mark. The password entry item 60 is composed of a plurality of key items, and numbers and alphabets are associated with each key item.

As shown in FIG. 12 (b), a legitimate user always fills in the name item and address item using the electronic pen 10, and the key item corresponding to the correct password must be entered in the password entry item 60. Specify the password by filling in the check mark. For example, when the password is “1486”, the user enters check marks in the key items corresponding to the numbers in order. This embodiment can also be applied when the password is a duplicated number such as “1111”. In this case, the user enters a check mark four times in the key item corresponding to the number “1”. . Finally, by filling a check mark in the transmission box 39, entry information corresponding to the contents entered in the electronic pen form 3b is transmitted to the server 5b via the terminal device 25.

  The server 5b extracts the authentication entry information entered in the password entry item 60 from the entry information based on the definition information described later. Further, the server 5b specifies the password specified in the password entry item 60 based on the coordinate information and time information included in the authentication entry information. Specifically, the server 5b specifies a key item in which a check mark is entered based on the coordinate information, and specifies a number or alphabet associated with the key item. Furthermore, the server 5b specifies the order in which check marks are entered in the specified key items based on the time information. The password designated by the user in the password entry item 60 can be identified by the identified number, alphabet, and entry order. The server 5b stores a correct password in advance, and determines whether the entry information is valid data or illegal data by determining whether or not it matches the specified password.

  In the present embodiment, as shown in FIG. 12, the key items constituting the password entry item 60 are associated with numbers or alphabets, but the present invention is not limited to this, and is set correctly. If a password can be specified, it is possible to arbitrarily set what symbol or character is associated with the key item.

(Ii) Server Next, the server 5b in the second embodiment will be described in detail. FIG. 13 shows an internal configuration of the server 5b in the processing system 200 of the second embodiment. As illustrated, the server 5b includes an authentication program 201, an entry information acquisition function 202, definition information 203, an authentication entry information extraction function 204, a password identification function 205, an authentication determination function 206, an authentication function 207, and a data processing execution function 208. Have. Each function is realized by the CPU of the server 5b executing a program prepared in advance.

  The authentication program 201 is a program that extracts the authentication entry information entered in the password entry item 60 from the entry information and identifies the password designated by the user based on the authentication entry information. The authentication program 201 is a program that authenticates the entry information as regular data and executes predetermined data processing when the specified password is a correct password. Further, the authentication program 201 is a program that, when the password cannot be specified and when the specified password is not a correct password, determines that the entry information is invalid data and registers it as unauthorized entry information.

  The entry information acquisition function 202 is a function for acquiring entry information corresponding to the contents entered in the electronic pen form 3 from the electronic pen 10.

  The authentication entry information extraction function 204 is a function that refers to the definition information 203 and extracts the authentication entry information corresponding to the contents entered in the password entry item 60 from the entry information obtained by the entry information acquisition function 202. Here, the definition information 203 will be described in detail with reference to FIG. FIG. 14 is a diagram schematically illustrating the data structure of definition information. As illustrated, the definition information 203 includes an item ID, an item name, a key, and coordinate information. The item ID is the name of each item, for example, “password entry item”, “name item”, “address item”, and the like. The key relates to a key item constituting the password entry item 60, and stores numbers and alphabets associated with each key item. The coordinate information is position coordinates indicating the arrangement of each item on the dot pattern. As shown in the figure, only the password entry item stores the position coordinates indicating the arrangement on the dot pattern for each key item constituting the password entry item. The authentication entry information extraction function 204 refers to the coordinate information of the definition information as shown on the basis of the coordinate information included in the entry information, and responds to the contents entered in the password entry 60 from the entry information. Authentication entry information can be extracted.

  The password specifying function 205 has a check mark entered by the electronic pen 10 by referring to the coordinate information of the definition information based on the coordinate information included in the authentication entry information extracted by the authentication entry information extraction function 204. The number or alphabet associated with the key item is specified. Note that the check mark in this embodiment is one stroke. Further, the password specifying function 205 specifies the order in which the key items for which check marks have been entered by the electronic pen 10 are entered based on the time information included in the authentication entry information. In other words, the number or alphabetical order associated with the key item is specified. Then, the password identification function 205 identifies the password designated by the user in the password entry item 60 based on the identified number or alphabet and the entry order.

  The authentication determination function 206 is a function that compares the password specified by the password specifying function 205 with the correct password stored in advance in the server 5b and determines whether or not they match.

  The authentication function 207 is a function for authenticating that the entry information acquired by the entry information acquisition function 202 is legitimate data by an authorized user when it is determined that the specified password matches the correct password. On the other hand, when it is determined that the specified password does not match the correct password, the authentication function 206 is a function that determines that the entry information acquired by the entry information acquisition function 202 is unauthorized data by an unauthorized third party. The authentication function 207 also determines that the entry information is illegal data even when the authentication entry information extraction function 204 cannot extract the authentication entry information or when the password identification function 205 cannot identify the password. . The entry information determined to be unauthorized data is registered in the unauthorized registration DB 6 as unauthorized entry information.

  The data processing execution function 208 is a function that executes predetermined data processing based on the entry information that is authenticated as normal data by the authentication function 207.

(Iii) Authentication Process Next, an authentication process executed by the processing system 200 of the second embodiment will be described. FIG. 15 is a flowchart of the authentication process in the second embodiment.

  Note that the correct password is disclosed in advance to the authorized user. The server 5b stores a correct password in advance.

  Using the electronic pen 10, the user fills in necessary items on the electronic pen form 3b. At this time, the legitimate user designates a correct password by entering a check mark in the key item in the password entry item 60. In response to a user's instruction, the electronic pen 10 transmits entry information corresponding to the contents entered in the electronic pen form 3b to the server 5b.

  The server 5b has definition information in advance that defines the items constituting the electronic pen form and the coordinate information indicating the position coordinates of the corresponding items on the dot pattern. Further, the server 5b acquires entry information from the electronic pen 10 via the terminal device 25 (step S11). Then, the server 5b extracts the authentication entry information entered in the password entry item 60 from the entry information by referring to the definition information (step S12). Further, the server 5b specifies the password designated by the user in the password entry item 60 based on the coordinate information and time information included in the extracted authentication entry information and the definition information (step S13). Then, the server 5b compares the specified password with the correct password stored in advance, and determines whether or not they match (step S14). When the specified password matches the correct password (step S14; Yes), the server 5b authenticates the entry information as regular data (step S15). Furthermore, the server 5b executes predetermined data processing based on the entry information that has been authenticated as regular data (step S16), and completes the authentication processing. On the other hand, if the specified password does not match the correct password (step S14; No), the server 5b determines that the entry information is invalid data (step S17). Further, the server 5b registers the entry information determined to be unauthorized data in the unauthorized registration DB 6 (step S18). That is, the data processing based on the entry information determined to be unauthorized data is not executed, and the authentication processing ends.

  In this embodiment, it is assumed that the server 5b stores the correct password in advance, but the password setting method is “set for each electronic pen form”, “set for each pen ID”, “monthly”. And various methods such as “set weekly”. That is, the password setting method in the present invention is arbitrary. The latest password is always disclosed to the authorized user, and the latest password is always stored in the server 5b.

  In this embodiment, the entry information determined to be unauthorized data is registered in the unauthorized registration DB 6, but the present invention is not limited to this and is used for predetermined data processing. It is good also as deleting.

As described above, according to the present embodiment , the electronic pen form 3 is provided with the password entry item 60 for designating the password, and the correct password is disclosed only to the authorized user. Therefore, when the password specified in the password entry item 60 is a correct password, the server 5b authenticates that the entry information is regular data, and executes predetermined data processing based on the entry information. On the other hand, if the password specified in the password entry item 60 is not a correct password, it is determined that the entry information is unauthorized data, and the entry information is separately registered in the unauthorized registration DB 6 as unauthorized entry information. Thereby, the server 5b can prevent the process based on the entry information by an unauthorized third party. In other words, by verifying the validity of the password, it is possible to eliminate unauthorized processing and unauthorized registration of entry information.

  In the first embodiment and the second embodiment, the server 5 has various functions. However, the present invention is not limited to this, and the terminal device 25 has a part or all of the functions. It is good as well. That is, the authentication process may be performed by a process completed by the terminal device 25 itself. In this case, the terminal device 25 does not need to be connected to the network 2 and may be a stand-alone device.
