Description

[Technical Field]

[0001] The present invention relates to a wireless tag authentication test system, and more particularly to specifying a position within an authentication area where an authentication test is to be performed. [Background technology]

[0002] There is a system form that uses a hands-free authentication device as an access control system introduced to facilities such as buildings. In this access control system, a hands-free antenna (hereinafter referred to as "HFA") having an antenna part and a controller part is installed near the door of a room in the facility, and a wireless tag that stores unique identification information and has the function of transmitting that unique identification information is carried by facility users.

[0003] When a facility user approaches within a specified range of the door, the wireless tag sends back a response signal in response to the inquiry signal from the HFA. The response signal contains the unique identification information held by the wireless tag, so the HFA performs authentication based on the unique identification information received from the wireless tag. If the authentication is successful, the door is unlocked.

[0004] In this way, facility users can simply approach the door and it will automatically unlock, eliminating the need to hold an IC card over a card reader. For this reason, hands-free authentication devices are suitable for use in facilities where hands are likely to be occupied.

[0005] Incidentally, when a short wave such as the UHF band is used to transmit a signal from a wireless tag to an HFA, even if the wireless tag enters the desired range, i.e., the range where it is necessary to receive the unique identification information recorded in the wireless tag and perform authentication accurately (hereinafter referred to as the "authentication area"), there is a possibility that the HFA will not be able to properly receive the radio signal transmitted by the wireless tag due to the influence of reflected waves, etc. In other words, just because the HFA is close to the HFA, in other words, just because the reception strength is strong, does not necessarily mean that the HFA will be able to properly receive the radio signal from the wireless tag.

[0006] Therefore, conventionally, before the system begins operation, a tester carries a wireless tag and moves around the authentication area to perform a wireless tag authentication test to determine whether authentication is performed correctly within the authentication area. In the authentication test, to confirm that authentication is performed correctly regardless of the wireless tag's position within the authentication area, for example, a marker indicating the position where the test will be performed is placed on the floor of the authentication area in advance. The tester then checks whether authentication is performed correctly when he or she is at the marker's position. Then, if necessary, the HFA installation position is fine-tuned to ensure accurate authentication within the authentication area. [Prior art documents] [Patent documents]

[Figure 2] FIG. 2 is a hardware configuration diagram of a mobile terminal according to the present embodiment. [Figure 3] 1 is a block diagram showing a configuration of a mobile terminal and an HFA according to the present embodiment. [Figure 4] 10 is a flowchart showing a tag authentication test process according to the present embodiment. [Figure 5] FIG. 10 is a conceptual diagram of a part of an authentication area viewed from above in this embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0020] FIG. 1 is a conceptual diagram illustrating a usage form of a RFID tag authentication test system according to this embodiment. FIG. 1 shows a room 2 in which an authentication test of a RFID tag (hereinafter simply referred to as a "tag") 1 is performed by the RFID tag authentication test system according to this embodiment. The tag 1 stores identification information unique to the tag (hereinafter "unique identification information") and has the function of transmitting the unique identification information by radio wave signals. The room 2 is an example of a space provided in a facility such as a building. A hands-free antenna (HFA) 4 is installed near a door 3 that serves as an entrance and exit to the room 2. The installation position of the HFA 4 before the test is performed is a temporary position. The installation position of the HFA 4 is determined by performing an authentication test, which will be described later. The "authentication test" in this embodiment refers to a test to confirm whether the HFA 4 can accurately authenticate the tag 1. The HFA 4 is an example of a reader that reads the unique identification information by receiving a telephone signal transmitted by the tag 1.

[0021] The facility where the authentication test for tag 1 is conducted has installed an access control system that uses a hands-free authentication device that employs HFA 4 and tag 1. When the access control system is in operation, tag 1 is carried by each facility user. The facility user carries tag 1 as they move around the facility. When the facility user approaches within a specified range of door 3 of room 2, HFA 4 acquires unique identification information from the radio signal emitted from tag 1 and authenticates tag 1 based on that unique identification information. If authentication is successful, door 3 is unlocked.

[0022] The detection range of the tag 1 by the HFA 4 can be individually set depending on the space in which the HFA 4 is installed. This detection range is basically specified by a facility manager or the like, but it is necessary that the HFA 4 can reliably detect the tag 1 within the specified range and accurately authenticate the tag 1 based on the unique identification information. In this embodiment, this detection range is referred to as the "authentication area," which indicates the range within which the HFA 4 performs an authentication test on the tag 1. The RFID tag authentication test system in this embodiment is used to perform tests so that the HFA 4 can accurately authenticate the tag 1 when the tag 1 is located within the authentication area. In other words, the authentication test on the tag 1 is performed before the access control system begins operation, and this authentication test determines the installation position of the HFA 4 to be a position that can accurately authenticate the tag 1 regardless of where the tag 1 is located in the authentication area.

[0023] 1 is an example of a mobile object, and is a worker who performs an authentication test on the tag 1. The tester 5 carries the tag 1 and a portable terminal 6 when performing the authentication test on the tag 1.

[0024] FIG. 1 also shows the authentication area 7 described above. In this embodiment, the room 2 is not provided with any markers or other markings to indicate the authentication area 7, but is shown for ease of explanation. In this embodiment, the authentication area 7 is shown as a rectangle, as shown in FIG. 1. The shape, size, and positional relationship of the authentication area 7 with respect to the HFA 4 are individually determined depending on the space in which the HFA 4 is installed, as described above. However, for convenience, the authentication area 7 is shown as a rectangle. In this embodiment, the authentication area 7 is divided into a plurality of rectangular cells 71 on a two-dimensional plane. The size of the cells 71 is determined according to the body size of the tester 5. In this embodiment, a size of, for example, 50 cm square is assumed, but this size is not necessarily required. The authentication area 7 is divided into a grid pattern as shown in FIG. 1. As will be described in detail later, in this embodiment, the test positions where the authentication test of the tag 1 is performed are identified by grid points 72.

[0025] In addition, since the HFA 4 is installed inside the room 2 in Figure 1, the case where the exit HFA 4 performs the authentication test of the tag 1 is illustrated. However, the HFA may be installed outside the room 2, in which case the entry HFA performs the authentication test of the tag.

[0026] 2 is a hardware configuration diagram of the mobile terminal 6 in this embodiment. The mobile terminal 6 in this embodiment is an example of an information processing device used to proactively perform an authentication test. In this embodiment, a smartphone is assumed as the mobile terminal 6, but a tablet terminal, a portable PC, or the like may also be used.

[0027] The mobile terminal 6 is configured by a camera 61, a distance measurement sensor 62, a communication interface (IF) 63, a storage 64, a user interface (UI) 65, and a control device 66, all connected via a bus 67. The camera 61 is provided as an imaging means capable of capturing still and moving images. The distance measurement sensor 62 measures the distance from the mobile terminal 6 to a target object. The method for measuring the distance does not need to be particularly limited, but for example, an optical LiDAR (Light Detection and Ranging) may be used. In recent years, smartphones equipped with a LiDAR function as standard have appeared, and it is convenient to use such models. If the mobile terminal 6 does not have a distance measurement sensor, the tester 5 may separately prepare a distance measurement sensor when conducting the certification test.

[0028] The communication interface 63 performs wireless communication with the HFA 4. The wireless communication method does not need to be particularly limited. The storage 64 is provided as a storage means. The user interface 65 is realized by a touch-type liquid crystal panel that serves as both an input means and a display means. The control device 66 is a control means that controls the operation of the components 61 to 65. The control device 66 is realized by a CPU that executes programs stored in ROM and RAM.

[0029] Fig. 3 is a block diagram showing the configuration of the portable terminal 6 and the HFA 4 in this embodiment. The portable terminal 6 has the control device 66 as shown in Fig. 2, and the control device 66 has an image data acquisition unit 661, an AR (Augmented Reality) processing unit 662, a display control unit 663, and a test execution control unit 664. Note that components not used in the description of this embodiment are omitted from the figure.

[0030] The image data acquisition unit 661 acquires image data captured by the camera 61 (hereinafter referred to as "captured data").

[0031] When the AR processing unit 662 acquires, using AR technology, image data from the image data acquisition unit 661 in which the HFA 4 and the entire authentication area 7 fall within the image capture range as described below, the AR processing unit 662 generates a grid image as a digital image with the HFA 4 shown in the image capture data as the origin of coordinates, and links the grid image to the authentication area 7. When the camera 61 is capturing an image of the authentication area 7, the AR processing unit 662 functions as a data generation means that generates video data by superimposing the grid image on the authentication area 7 in the image capture data. The AR processing unit 662 also detects that the tag 1 matches the position of a grid point in the grid image.

[0032] The display control unit 663 controls the display on the user interface 65. In this embodiment, the user interface 65 is mainly used as a display means, and therefore, for convenience of explanation, it will be referred to as the "display unit 65" in the following description.

[0033] The test execution control unit 664 controls the execution of an authentication test on the tag 1. For example, when the test execution control unit 664 detects that the positions of the tag 1 and the lattice point 72 match, the test execution control unit 664 functions as a test request means that requests an authentication test on the tag 1. Furthermore, when the test execution control unit 664 acquires result information of the authentication test on the tag 1 that was performed in response to the authentication test request, the test execution control unit 664 functions as a recording means that associates the result information with test position information that indicates the position of the lattice point 72 whose position matches that of the tag 1 and records the result information. Specifically, the test execution control unit 664 registers a pair of the result information and the test position information in the test result information storage unit 641 realized by the storage 64.

[0034] Each of the components 661 to 664 in the control device 66 is realized by the cooperative operation of a CPU forming the control device 66 and a program running on the CPU. The program used in this embodiment can be provided not only by communication means, but also by being stored on a readable recording medium. The program provided from the communication means or recording medium is installed on the mobile terminal 6, and various processes are realized by the CPU sequentially executing the program.

[0035] The HFA 4 has a wireless communication processing unit 41, an authentication processing unit 42, and an authentication information storage unit 43. The wireless communication processing unit 41 performs wireless communication between the portable terminal 6 and the tag 1. The authentication information storage unit 43 stores, as authentication information, the unique identification information recorded in the tag 1 carried by the tester 5, and the authentication processing unit 42 performs authentication processing by comparing the unique identification information included in the radio signal received from the tag 1 with the authentication information.

[0036] During system operation, if authentication is successful, door 3 is unlocked, but since this is an authentication test, it does not matter whether door 3 is unlocked or not. Also, while the unique identification information used for the test is stored in authentication information storage unit 43 of HFA 4, it is not limited to this, and the information may be stored in a management server of the access control system or the like, and the management server or the like may be inquired about the success or failure of authentication during the authentication test. In any case, the HFA 4 can utilize existing devices that are used during system operation.

[0037] Next, the operation of this embodiment will be described.

[0038] In this embodiment, the HFA 4 receives unique identification information transmitted by a tag 1 located within the authentication area 7 and verifies whether authentication can be performed accurately based on the unique identification information. As described above, when a short wave such as a UHF band is used to transmit a radio signal from the tag 1 to the HFA 4, there is a possibility that the HFA 4 will not be able to properly receive the radio signal transmitted by the tag 1 due to the influence of reflected waves, etc. In other words, just because the reception strength is strong does not necessarily mean that the HFA will be able to correctly receive the unique identification information from the tag 1. For this reason, at each test position in the authentication area 7, an authentication test of the tag 1 is performed to determine whether authentication can be performed correctly using the unique identification information received from the tag 1 by the HFA 4. The process of performing the authentication test of the tag 1 in this embodiment will be described below using the flowchart shown in FIG. 4. Note that the term "authentication test" of the tag 1 may refer, in a narrow sense, to an authentication test performed at a single test position, or, in a broad sense, to tests performed at each test position collectively referred to as "authentication test." The process performed in response to a request in step 160 corresponds to the former, and the authentication test process shown in FIG. 4 corresponds to the latter.

[0039] First, the examiner 5 operates the camera 61 to take a photograph, a so-called still image, from a position where the HFA 4 and the entire authentication area 7 are within the shooting range. The image data acquisition unit 661 acquires from the camera 61 the photographed data generated by the examiner 5 taking the photograph (step 110).

[0040] Next, when the AR processing unit 662 acquires the photographed data from the image data acquisition unit 661, it generates a grid image as a digital image by drawing lines in a grid pattern, using the HFA 4 shown in the photographed data as the starting point of coordinates (step 120). A grid (also called a "grid") represented on a two-dimensional plane, which corresponds to this grid image, is shown in FIG.

[0041] In this embodiment, as described above, a grid of, for example, 50 cm square is formed to fit the body size of the examinee 5. The grid image is synthesized with the photographed data so that it is projected at a height of, for example, 130 cm from the floor.

[0042] Next, when conducting the authentication test, the tester 5 moves within the authentication area 7, while capturing the direction of movement (progression) with the camera 61. At this time, the AR processing unit 662 uses AR technology to superimpose the grid image generated in step 120 onto the authentication area 7 included in the real-world captured data generated by the camera 61, and generates video data to be displayed on the display unit 65 in real time. More specifically, as the tester 5 moves, the AR processing unit 662 detects the direction and speed of movement of the tester 5, which can be measured by an acceleration sensor or the like (not shown) provided in the mobile terminal 6, as well as the capturing range of the camera 61, and generates video data to be displayed on the display unit 65 in real time, as described above. The display control unit 663 displays the video data generated by the AR processing unit 662 on the display unit 65 (step 130). As a result, when the tester 5 looks at the display unit 65, it appears as if a grid is drawn in the authentication area 7, even though it is not actually drawn.

[0043] The examiner 5 moves through the authentication area 7 holding the tag 1 while watching the video data displayed on the display unit 65. The examiner 5 then aligns the position of the tag 1 he or she is carrying with the grid points displayed virtually on the screen.

[0044] FIG. 5 is a conceptual diagram of a portion of the authentication area 7 viewed from above, and shows only a part of the grid image 8. Furthermore, the tester 5 shown in FIG. 1 is omitted from FIG. 5, and only the tag 1 held by the tester 5 is shown. Furthermore, in FIG. 5, the tag 1 is shown transparently for the sake of convenience, so that the positions of the grid points 82a, 82b, and 82c can be confirmed. When the grid points 82a, 82b, and 82c are described without distinction, they will be collectively referred to as "grid point 82."

[0045] The examiner 5 moves through the authentication area 7 and adjusts the position of the tag 1 so that it aligns with one of the grid points 82 identified by the grid image. Note that the display unit 65 displays video data corresponding to the shooting range of the camera 61, and the examiner 5 aligns the tag 1 with the grid point 82 displayed on the display unit 65, so that the tag 1 is also photographed by the camera 61 and displayed on the display unit 65. Therefore, the examiner 5 attempts to align the position of the tag 1 displayed on the display unit 65 with the position of one of the grid points 82 also displayed on the display unit 65. In other words, the examiner 5 moves while looking at the display unit 65 so that the position of the tag 1 overlaps with the position of the grid point 82.

[0046] The AR processing unit 662 appropriately updates the image data displayed on the display unit 65 until the tester 5 matches the position of the tag 1 with the position of the lattice point 82 (N in step 140). Then, when the image of the tag 1 displayed on the display unit 65 overlaps with the image of one of the lattice points 82, detecting that the tester 5 has matched the position of the tag 1 with the position of one of the lattice points 82 (Y in step 140), the AR processing unit 662 notifies the tester 5 that it has detected a match between the position of the tag 1 and the position of the lattice point 82, i.e., the test position, by displaying a message on the display unit 65 (step 150). This allows the tester 5 to stand still while maintaining the position of the tag 1 so that it does not deviate from the position of the lattice point 82, until the authentication test at the position of that lattice point 82 (test position) is completed.

[0047] In this embodiment, the AR processing unit 662 functions as a notification means for notifying the examiner 5 by displaying on the display unit 65, but the method of notifying the examiner 5 is not limited to this, and for example, the AR processing unit 662 may function to notify the examiner 5 by outputting sound or light to the mobile terminal 6.

[0048] When the tester 5 learns from the notification from the AR processing unit 662 that the position of the tag 1 matches the test position, the test execution control unit 664 requests test communication from the HFA 4 by sending a predetermined authentication test request via the communication interface 63 in response to a predetermined operation by the tester 5 (step 160).

[0049] In this embodiment, the test communication is requested in response to an instruction from the tester 5, but the request may also be made automatically when it is detected that the position of the tag 1 coincides with the position of the lattice point 82.

[0050] When the authentication processing unit 42 in the HFA 4 receives a request from the portable terminal 6 via the wireless communication processing unit 41, it starts an authentication test of the tag 1. The authentication test is performed, for example, as follows.

[0051] First, the authentication processing unit 42 transmits an inquiry signal to the tag 1. The tag 1 returns a response signal in response to the inquiry signal from the HFA 4. This response signal includes its own unique identification information.

[0052] When the authentication processing unit 42 receives a response signal from the tag 1, it compares the unique identification information included in the response signal with the unique identification information set in the authentication information storage unit 43, and if they match, it determines that the authentication has been successful. This signal exchange with the tag 1 is repeated a specified number of times. Then, if the number of successful authentications out of the specified number of times is equal to or greater than a predetermined threshold, it ultimately determines that the authentication has been successful. The authentication processing unit 42 transmits result information including the results of this authentication test to the mobile terminal 6. Note that the authentication processing unit 42 may include in the transmitted result information not only the authentication result but also information such as the specified number of times signals were exchanged and the number of successful exchanges out of the specified number of times.

[0053] When the result information transmitted from the HFA 4 in response to the test communication request, i.e., the result of the authentication test, is received (step 170), the test execution control unit 664 associates the received result information with test position information indicating the position of the lattice point 82 whose position matches that of the tag 1, and records the result information in the test result information storage unit 641 (step 180). The test position information to be included in the test position information is obtained from the AR processing unit 662.

[0054] In this embodiment, the test results at each test position are recorded in the test result information storage unit 641, so that the test results at each test position can be confirmed after the authentication test of the tag 1 is completed.

[0055] In this embodiment, the test results at each test position are recorded in the test result information storage unit 641, but this is not limited to this, and the results may also be sent to, for example, an administrator's terminal device via a network.

[0056] After recording the results of the authentication test in the above manner, the test execution control unit 664 notifies the tester 5 that the authentication test at one lattice point 83 has been completed by displaying a message on the display unit 65 (step 190). Note that the authentication result may also be displayed in addition to the message that the authentication test has been completed.

[0057] Conventionally, authentication results have been confirmed by visually checking an indicator on the surface of the HFA 4. In other words, to determine whether the authentication test passed or failed, the tester had to visually check the indicator from a position away from the HFA 4 or from a position at an angle. In this embodiment, the indicator is displayed on a portable display unit 65, so the completion of the authentication test and the test results can be checked at hand.

[0058] In this embodiment, the test execution control unit 664 functions as a notification means for notifying the tester 5 by displaying on the display unit 65, but the method of notifying the tester 5 is not limited to this, and for example, the test execution control unit 664 may function to notify the tester 5 by outputting sound or light to the mobile terminal 6.

[0059] The tester 5 is notified by the test execution control unit 664 that the authentication test has ended at the lattice point 82 where the tag 1 is aligned, but if the authentication test has not been performed at all lattice points 82 (N in step 200), the tester 5 moves to align the tag 1 with a lattice point 82 where the test has not yet been performed. The AR processing unit 662 updates the video data in accordance with the movement of the tester 5 and displays it on the display unit 65 (step 130).

[0060] Then, when the authentication test is performed at all the lattice points 82 (Y in step 200), the authentication test for the entire authentication area 7 is completed.

[0061] As described above, according to this embodiment, AR technology is used to superimpose a grid image on the authentication area 7 included in the captured data, so that the authentication area 7 can be identified without placing markers on the floor, and further, the test position can be identified by the grid points of the grid image.

[0062] Incidentally, in the above explanation, it was explained that the tester 5 aligns the position of the tag 1 with the position of one of the lattice points 82 displayed on the display unit 65. However, it is considered that the tester 5 does not select the lattice point 82 at random, but basically starts from the lattice point 82 that forms one corner of the authentication area 7 and searches for the lattice points 82 in order.

[0063] 5, if the tester 5 moves in the direction of arrow A and completes an authentication test at lattice point 82a, and then moves in the direction of arrow B, it is considered that the tester 5 will perform an authentication test at lattice point 82b, which is adjacent in the direction of arrow B. Then, after completing the authentication test at lattice point 82b, it is considered that a typical procedure for performing an authentication test is to move, for example, in the direction of arrow C, which is the same as the directions of arrows A and B, and perform an authentication test at lattice point 82c, which is adjacent in the direction of arrow C. Of course, this is a typical example, and the lattice point 82 on which the authentication test is next performed does not necessarily have to be in an adjacent position, but basically, by performing authentication tests on adjacent lattice points 82 in order, the tester 5 can efficiently perform authentication tests on tags 1 without omission at all test positions included in the authentication area 7.

[0064] The AR processing unit 662 may display a grid image in such a way that grid points 82 for which the authentication test has been completed can be distinguished from grid points 82 for which the authentication test has not been completed, by changing the display format of the grid points 82. Also, a recommended movement direction may be displayed to present to the tester 5, as shown by the arrows in FIG. 5. This allows the tester 5 to easily find grid points 82 for which the authentication test has not been completed.

[0065] In the above explanation, the tester 5 is described as an example of a moving body. However, the tester does not necessarily have to be the tester 5, and it is also possible to use, for example, an autonomously moving robot whose movement is controlled by the tester. In this case, the robot will be equipped with the tag 1 and a photographing means and will move through the authentication area 7, and the tester 5 will control the movement of the robot while watching the display means that displays the video data.

[0066] In addition, in this embodiment, the mobile terminal 6 directly requests test communication from the HFA 4. However, in cases where the HFA 4 does not have a function for wireless communication with the mobile terminal 6, the mobile terminal 6 may indirectly request test communication from the HFA 4 by transmitting a predetermined authentication test request to another device, such as a management server of an access control system.
