FIG. 5 is a diagram for explaining the outline of the process for displaying information on the electronic paper. Assume that the electronic paper 2 is not displaying character information or image information. The authentication device 3 displays the arrangement image 30 shown in FIG. As shown by the tip of the arrow in the figure, when the user correctly overlays the electronic paper 2 on the arrangement image 30 displayed on the authentication device 3, character information, image information, etc. are displayed on the electronic paper 2. .

FIG. 6 is a diagram for explaining the outline of the information non-display process on the electronic paper. It is assumed that character information, image information, etc. are displayed on the electronic balance 2. The authentication device 3 displays the arrangement image 30 shown in FIG. As shown by the tip of the arrow in the figure, when the user correctly overlays the electronic paper 2 on the arrangement image 30 displayed on the authentication device 3, the electronic paper 2 The text information and image information displayed on paper 2 are hidden.

FIG. 7A, FIG. 7B, and FIG. 8 are diagrams for explaining detection of counterfeiting of electronic paper using the information display device of the present invention. It is assumed that the electronic paper 2 includes a position detection unit 21 and an information processing unit 22, and the authentication device 3 includes a position detection unit 31, an information processing unit 32, and a determination processing unit 33. Further, it is assumed that the determination processing means 33 of the authentication device 3 performs position authentication processing based on the position detection result by the position detection means 31. Assume that electronic paper 100 is forged from genuine electronic paper 2 as shown in FIG. Since the result of position authentication processing for the electronic paper 100 by the judgment processing means 33 of the authentication device 3 is authentication (A: Available), it cannot be detected that the electronic paper 100 has been forged.

According to one embodiment of the present invention, for example, as shown in FIG. 7B, the electronic paper 2 includes a determination processing unit 23 in addition to the position detection unit 21 and the information display unit 22.

If the electronic paper 2 is genuine, the position authentication processing result and the device authentication processing result for the electronic paper 2 by the judgment processing means 33 of the authentication device 3 are authentication (A: Available).

For the counterfeited electronic paper 101 shown in FIG. 8, the result of the position authentication processing by the judgment processing means 33 of the authentication device 3 is authentication (A). However, since the judgment processing means 23 of the real electronic paper 2 shown in FIG. 7B is realized by, for example, a TCG chip or the like, it is difficult to forge. In addition, since the device HD information of genuine electronic paper 2 is stored, for example, in the judgment processing means 23, the device authentication processing result for forged electronic paper 101 is not certified (NZA : Not Available) and it can be detected that the electronic paper 101 is forged. Similarly, the device authentication processing result for the electronic paper 102 shown in FIG. 8 is also unauthenticated (NZA), and it can be detected that the electronic paper 102 has been forged. It should be noted that forgery of the authentication device 3 can be detected by a method similar to the forgery detection method of the electronic paper 2 described above.

[0040] FIG. 9 is a diagram showing an example of a data flow according to an embodiment of the present invention. The position detection means 21 of the electronic balance 2 and the position detection means 31 of the authentication device 3 are connected to the electronic paper 2. The relative position of the authentication device 3 is detected.

[0045] FIGS. 14A and 14B are diagrams illustrating examples of cross sections of electronic paper and an authentication device. The position detection means 21 of the electronic paper 2 shown in FIG. 14 (A) is a passive RFID tag. Further, the position detection means 31 of the authentication device 3 is an RFID tag reader. FIGS. 14A and 14B show an example in which the electronic paper 2 is stacked on the authentication device 3. An RFID tag reader (position detection means) 31 shown in FIG. 14 (A) transmits an electromotive wave to the position detection means (RFID tag) 21. For electromotive waves, the size and thickness of the RFID tag 21 are reduced. For example, in order to avoid interference with radio waves when the information transmission / reception means 25 and the information transmission / reception means 35 perform wireless LAN communication, for example, a frequency of 13.56 MHz is used. The RFID tag 21 that has received the electromotive wave from the R FID tag reader 31 returns a signal radio wave including identification information (for example, an ID number) of the RFID tag 21 to the RFID tag reader 31, and the RFID tag reader 31 receives the RFID tag 21.

[0047] Returning to FIG. 14A, the TCG chip 201 in the authentication device 3 has the ID number read by each RFID tag reader 31 set in advance, and the electronic paper 2 is correctly placed on the authentication device 3. When it is overlaid on each other, it is determined whether each RFID tag reader 31 matches the ID number of the RFID tag to be read. When the ID number power read by each RFID tag reader 31 matches the preset ID number, the TCG chip 201 authenticates the position of the electronic paper 2. Note that, according to one embodiment of the present invention, in FIG. 14A, the electronic paper 2 may include an RFID tag reader as the position detection means 21, and the authentication device 3 may include an RFID tag as the position detection means 31. ,.

The optical signal from the force LED 21 is detected only by the optical sensor 31 indicated by the shaded area without detecting the optical signal from the force. The determination processing means 33 (not shown in FIG. 17) of the authentication device 3 is such that the optical sensor 31 that detects the optical signal is a preset optical sensor, and the electronic paper 2 is correctly arranged image 30 of the authentication device 3. Judge whether the optical signal matches the optical sensor that should be detected when overlaid. When the optical sensor 31 that has detected the optical signal matches the preset optical sensor, the determination processing means 33 authenticates the position of the electronic paper 2.

FIG. 19 is a diagram showing the authentication device 3 overlaid on the RFID tag reader 31) shown in FIG. 18 (B), which is shown in black, and the ID number of the RFID tag 21 is read. When the RFID tag reader 31 that has read the ID number of the RFID tag 21 is a preset RFID tag reader and the electronic paper 2 is correctly superimposed on the arrangement image 30 of the authentication device 3, the authentication device 3 The ID number of the RFID tag 21 should be read. Judge whether it matches the RFID tag reader. When the RF ID tag reader 31 that has read the ID number of the RFID tag 21 matches the preset RFID tag reader, the determination processing unit 33 authenticates the position of the electronic paper 2.

As shown in FIG. 19 (B), when the rectangular arrangement image 30 is displayed on the authentication device 3, for example, the user authenticates the electronic paper 2 shown in FIG. 19 (A) with the authentication shown in FIG. 19 (B). The electronic paper 2 is overlapped on the authentication device 3 by moving in the direction of the device 3 so that the side of the electronic paper 2 matches the outline of the arrangement image 30 displayed on the authentication device 3. As a result, the electronic paper 2 and the authentication device 3 are overlapped as shown in FIG. In the overlapping state as shown in FIG. 19C, the RFID tag 21 provided in the electronic paper 2 and the RFID tag reader 31 provided in the authentication device 3 are in the positional relationship as shown in FIG. 19D.

That's right! / In this case, the three RFID tag readers 31 surrounded by the dotted line in the upper left figure in Fig. 22 do not read the ID number of the RFID tag 21 provided in the electronic paper 1 2 and Is not displayed.

[0056] When the electronic paper 2 in which the RFID tags 21 are arranged in the arrangement shown in the lower right diagram of FIG. 22 is placed on the authentication device 3 shown in the upper left diagram of FIG. The side of 2 must be tilted and stacked with respect to the side of authentication device 3. That's right! / In this case, the three RFID tag readers 31 surrounded by the dotted line in the upper left figure in Fig. 22 do not read the ID number of the RFID tag 21 provided in the electronic paper 1, and the information is sent to the electronic paper 2. Is not displayed.

Further, according to one embodiment of the present invention, for example, as shown in the upper right diagram of FIG. 22, the RFID tag reader 31 is attached to the authentication device 3 with a predetermined angle with each side of the authentication device 3. They are arranged in a line. Also, for example, when the three RFI D tag readers 31 surrounded by the dotted line in the upper right figure in FIG. 22 read the ID number of the RFID tag 21 included in the electronic paper 2 in advance. In addition, the authentication device 3 is set to send display instruction information to the electronic paper 2.

[0058] Here, when the electronic balance 2 in which the RFID tags 21 are arranged in the arrangement shown in the lower right diagram of FIG. 22 is placed on the authentication device 3 shown in the upper right diagram of FIG. The side of the electronic paper 2 and the side of the authentication device 3 must be stacked in parallel. Yes, in the case of Fig. 22, the three RFID tag readers 31 surrounded by the dotted line in the upper right figure in Fig. 22 do not read the ID number of the RFID tag 21 provided in the electronic paper 1, and the information is stored in the electronic paper 2. Is not displayed.

In addition, when the electronic paper 2 in which the RFID tags 21 are arranged in the arrangement shown in the lower left diagram of FIG. 22 is stacked on the authentication device 3 shown in the upper right diagram of FIG. 22, the electronic paper 2 The side must be tilted with respect to the side of the authentication device 3 and stacked. Yes, in the case of Fig. 22, the three RFID tag readers 31 surrounded by the dotted line in the upper right figure in Fig. 22 do not read the ID number of the RFID tag 21 provided in the electronic paper 1, and the information is stored in the electronic paper 2. Is not displayed.

Another embodiment of the present invention will be described with reference to FIGS. 23 (A) to 23 (D).

FIGS. 23A to 23D illustrate cross sections of the electronic paper and the authentication device in a state where the electronic paper is overlapped with the authentication device. According to one embodiment of the present invention, for example, as shown in FIG. 23 (A), when the authentication device 3 is placed between the RFID tag 21 and the RFID tag reader 31 when the electronic paper 2 is stacked on the authentication device 3, A curved surface is formed so that there is a gap between them. Immediately after the electronic paper 2 is overlaid on the authentication device 3, as shown in the portion surrounded by the dotted ellipse in FIG. 23 (A), the RFID tag reader 31 placed at a position away from the central force of the authentication device 3 The distance from the RFID tag 21 provided in the electronic paper 2 is large. Therefore, the RFID tag reader 31 cannot read the ID number of the RFID tag 21. Here, when the user increases the pressure in the direction of the upper force authentication device 3 of the electronic paper 2, the electronic paper 2 is pressed against the authentication device 3, and the electronic paper 2 and the authentication device 3 are shown in FIG. The overlapping state is as shown in B). In the overlapping state as shown in FIG. 23 (B), the distance between the RFID tag reader 31 and the RFID tag 21 provided in the electronic bar 2 in the portion surrounded by the dotted ellipse in FIG. RFID tag reader 31 is RFID tag 21 This is a predetermined interval at which it can be detected. Therefore, the RFID tag reader 31 can read the ID number of the RFID tag 21 included in the electronic paper 2. The same applies when the electronic paper 2 is pressed against the authentication device 3 by the weight of the electronic paper 2 superimposed on the authentication device 3.

Further, according to one embodiment of the present invention, for example, the authentication device 3 is bent at a plurality of portions as shown in FIG. 23 (C). Immediately after the electronic paper 2 is stacked on the authentication device 3, the gap between the RFID tag reader 31 and the RFID tag 21 in the portion surrounded by the dotted line in FIG. 23 (C) is large. Therefore, the RFID tag reader 31 cannot read the ID number of the RFID tag 21. Here, when the user applies pressure from above the electronic paper 2 toward the authentication device 3, the electronic paper 2 is pressed against the authentication device 3, and the electronic paper 2 and the authentication device 3 are shown in FIG. ) As shown in FIG. Accordingly, the distance between the RFID tag reader 31 and the RFID tag 21 provided in the electronic paper 2 in the portion surrounded by the dotted ellipse in FIG. 23 (D) is small, and the RFID tag reader 31 is provided in the electronic paper 2. The ID number of the RF ID tag 21 can be read. The same applies when the electronic paper 2 is pressed against the authentication device 3 by the weight of the electronic paper 2 stacked on the authentication device 3.

[0062] In FIGS. 23A to 23D, the case where the authentication device 3 has a curved surface has been described as an example. However, when the electronic paper 2 overlaps the authentication device 3, the RFID is used. A curved surface configured to have a gap between the tag 21 and the RFID tag reader 31 may be formed. The case where the electronic paper 2 has a curved surface is the same as that shown in FIGS. 23 (A) to 23 (D). That is, for example, when the interval between the RFID tag reader 31 and the RFID tag 21 becomes a predetermined interval at which the RFID tag reader 31 can detect the RFID tag 21, the RFID tag reader 31 reads the ID number of the RFID tag 21.

FIG. 24 is a diagram showing an example of a display instruction information transmission process flow of the authentication apparatus. When the electronic paper 2 is stacked on the authentication device 3, the position detection means 31 of the authentication device 3 detects the position of the electronic vapor 2 (step Sl). For example, as indicated by SI-1 in FIG. 26, the position detection means 31 of the authentication device 3 makes a request for reading the identification information of the position detection means 21 provided in the electronic paper 2!識 The information contained in the response data sent from Electronic Paper 2 Read other information (see SI-2 and SI-3 in Fig. 26). Next, the determination processing means 33 determines whether or not the electronic paper 2 has been placed at a predetermined position based on the position detection result in step S1 (position authentication process) (step S2, S2-1 in FIG. 26). . If the electronic paper 2 is not stacked at the predetermined position, the process returns to step S1. When the electronic paper 2 is stacked at a predetermined position, the judgment processing means 33 performs device authentication processing with the electronic paper 2 (step S3). For example, as shown in S3-1 in FIG. 26, the determination processing means 33 encrypts the device ID and password of the authentication device 3 and transmits them to the electronic paper 2. As shown in S11-1 of FIG. 26, the electronic pair 2 decrypts the data received from the authentication device 3 and compares it with preset data to perform device authentication processing for the authentication device 3. Yeah. Further, for example, the judgment processing means 33 decrypts the data in which the device ID and the password of the electronic paper 1 transmitted from the electronic paper 2 are encrypted, compares the data with the preset data, and performs electronic verification. Device authentication processing for paper 2 is performed (S11-2 and S3 2 in Fig. 26).

[0064] Next, the determination processing means 33 determines whether the electronic paper 2 and the authentication device 3 have been mutually authenticated (step S4). If the electronic paper 2 and the authentication device 3 are not mutually authenticated, the process ends. If the electronic paper 2 and the authentication device 3 are mutually authenticated, the judgment processing means 33 sends display instruction information to the electronic paper 2 (step S5, S5-1 in FIG. 26), Display information on Paper 2 (SI 4 1 in Figure 26).

Note that the processing flow when the authentication device 3 sends the non-display instruction information to the electronic paper 2 is replaced by the determination processing means 33 for the non-display instruction information to the electronic paper 2 instead of step S5. Is the same as the processing flow shown in FIG.

FIG. 25 is a diagram showing an example of an electronic paper information display processing flow. The judgment processing means 23 of the electronic paper 2 performs device authentication processing with the authentication device 3 (step S11). Next, the determination processing means 23 determines whether the electronic paper 2 and the authentication device 3 have been mutually authenticated (step S12). If the electronic paper 2 and the authentication device 3 are not mutually authenticated, the process returns to step S11. When the electronic paper 2 and the authentication device 3 are mutually authenticated, the judgment processing means 23 receives the display instruction information from the authentication device 3. (Step S13). If display instruction information is not received from authentication device 3, the process ends. When the display instruction information is received from the authentication device 3, the determination processing means 23 sends a control signal to the information display means 22 to display character information, image information, etc. (step S14).

[0067] Note that the processing flow when the electronic paper 2 hides information replaces the above step S13 with the judgment processing means 23 judging whether it has received the non-display instruction information from the authentication device 3, and 25 is the same as the process flow shown in FIG. 25 except that the determination processing means 23 sends a control signal to the information display means 22 to hide the character information, the image information, etc. instead of step S14.

FIG. 27 (B) shows the authentication device 3 installed on the upper surface of the device 210 shown in FIG. 27 (A). As shown in FIG. 27B, the authentication device 3 displays a facility layout diagram 211. Each of the nine images with the letters "Equipment S01" to "Equipment S09" included in the equipment layout diagram 211 is an image showing the location of each equipment at the construction site, etc. This is an arrangement image 30 used when 2 is superimposed on the authentication device 3. “Equipment S01” to “Equipment S09” indicate the names of the facilities arranged at the construction site. When a field worker superimposes electronic paper 2 on a certain arrangement image 30, the authentication device 3 performs position authentication processing for all the electronic paper 2, and information on the equipment having the equipment name described in the arrangement image 30 is obtained. Displayed on electronic paper 2.

[0069] For example, as indicated by the arrow in FIG. 27 (B), the site worker fits the upper left corner of the arrangement image in which the characters “upper left corner force ^ equipment S07” of electronic paper 2 are described. Then, the electronic paper 2 is stacked on the authentication device 3. Accordingly, detailed information on the equipment having the equipment name of equipment S 07 is displayed on the electronic paper 2 (for example, failure information of the equipment, work instruction information about the equipment, work history information, information on the equipment) Information on entry procedures).

For example, at a questionnaire venue, the answer to the questionnaire is input to the electronic paper 2 (information storage means 24) as the user's 300 questionnaire shown in Fig. 28 (A), and the response content is displayed on the electronic paper 2 Let Thereafter, as shown in FIG. 28 (B), for example, the user 300 (or the questionnaire sheet collector) is placed on the authentication device 3 set to send the non-display instruction information to the electronic paper 2. Stack two pieces of electronic paper. In response to this, the response content is hidden on the electronic paper 2. Electronic paper 2 whose response contents are hidden can no longer be viewed by outsiders, and security is ensured when electronic paper 2 is carried outside the questionnaire venue. As shown in FIG. 28 (C), when the electronic paper 2 is overlaid on the authentication device 3 set to send display instruction information to the electronic paper 2, the response content is displayed and displayed. The response contents are used for the aggregate analysis process.
