Modes for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[0013] (Configuration of Finger Authentication Pre-Approval Determination System) FIG. 1 is a diagram showing an example in which a finger authentication pre-approval determination system 100 according to the present invention is applied near the entrance to the building of a power plant P. As shown in FIG. 1, the finger authentication pre-approval determination system 100 includes a server 1, a guiding device 2, a finger authentication approval determination device 3 (3A, 3B), a finger authentication device 4 (4A, 4B), and gates 5 (5A, 5B). The server 1 is connected to at least the finger authentication device 4 and the gates 5 via a communication network N.

[0014] Those permitted to enter (enter) the power plant P are divided into permanent visitors, such as employees of the power plant P, and temporary visitors, such as workers. Both types of visitors can enter the power plant P building only after their identity has been verified through fingerprint authentication. However, in winter, the low temperature often causes the temperature of the hands to drop, leading to poor blood circulation and making fingerprint authentication difficult. Permanent visitors are aware that fingerprint authentication is required, so many take measures such as warming their hands beforehand, resulting in relatively few instances of authentication failure. However, temporary visitors are often unaware that fingerprint authentication is required, leading to long queues and congestion. Therefore, in this embodiment, the fingerprint authentication pre-failure determination system 100 pre-determines whether a visitor can be authenticated by fingerprint authentication in the passageway 10 before the entrance to the power plant P building. If it is determined that fingerprint authentication is not possible, the visitor is guided to warm their hands before returning to the queue, thereby alleviating congestion caused by waiting for fingerprint authentication upon entry. Furthermore, by guiding permanent visitors and temporary visitors to separate lanes and conducting pre-screening and fingerprint authentication separately, congestion and delays caused by waiting for fingerprint authentication upon entry will be further reduced.

[0015] As shown in FIG. 1, in the present embodiment, a passage 10 leading to the entrance of the building of the power plant P is provided with a lane L1 (first lane) for permanent visitors and a lane L2 (second lane) for temporary visitors. Permanent visitors and temporary visitors enter the power plant P from different lanes. The passage 10, the lane L1 for permanent visitors, and the lane L2 for temporary visitors are provided with heaters 7 so that visitors can warm their fingers and the like. Near the branch point between the lane L1 for permanent visitors and the lane L2 for temporary visitors, a guiding device 2 equipped with a camera 24 (see FIG. 3) is provided. The guiding device 2 photographs the access permit held by the visitor with the camera 24, analyzes the obtained photographed image, and determines whether the visitor is a permanent visitor or a temporary visitor. Here, the access permit is described with identification information (for example, characters, codes (numbers, etc.), barcodes, two-dimensional codes, etc.) for identifying whether the visitor is a permanent visitor or a temporary visitor. Then, the guiding device 2 guides the visitor determined to be a permanent visitor to the lane L1 for permanent visitors and the visitor determined to be a temporary visitor to the lane L2 for temporary visitors.

[0016] In the lane L1 for permanent visitors and the lane L2 for temporary visitors, on the way from the lane entrance to the installation location of the fingerprint authentication device 4 and the gate 5, a fingerprint authentication availability determination device 3 for determining the availability of fingerprint authentication in advance is provided before fingerprint authentication is performed. Here, the fingerprint authentication availability determination device 3 provided in the lane L1 for permanent visitors is referred to as the fingerprint authentication availability determination device 3A, and the fingerprint authentication availability determination device 3 provided in the lane L2 for temporary visitors is referred to as the fingerprint authentication availability determination device 3B. Also, the fingerprint authentication device 4 provided in the lane L1 for permanent visitors is referred to as the fingerprint authentication device 4A, and the fingerprint authentication device 4 provided in the lane L2 for temporary visitors is referred to as the fingerprint authentication device 4B. Also, the gate 5 provided in the lane L1 for permanent visitors is referred to as the gate 5A, and the gate 5 provided in the lane L2 for temporary visitors is referred to as the gate 5B.

[0017] Finger authentication eligibility determination devices 3A and 3B detect the temperature of the fingers of visitors (persons to be authenticated) passing through the permanent visitor lane L1 and the temporary visitor lane L2, respectively, and determine whether the temperature of the visitor's fingers is above a predetermined threshold based on the detection results. If it is determined that the temperature of the visitor's fingers has not reached the predetermined threshold, the finger authentication eligibility determination devices 3A and 3B determine that finger authentication is not possible and guide the visitor to warm their fingers before returning to the lane. If it is determined that the temperature of the visitor's fingers is above the predetermined threshold, the finger authentication eligibility determination devices 3A and 3B determine that finger authentication is possible and guide the visitor to the finger authentication device 4 near the entrance of gate 5.

[0018] Finger authentication devices 4A and 4B are installed near the entrances of gates 5A and 5B, respectively, and acquire the fingerprint authentication information of visitors and transmit it to server 1. Finger authentication device 4 may be a fingerprint authentication device that reads the fingerprints of the fingers to authenticate visitors, or a finger vein authentication device that reads the vein patterns of the fingers to authenticate visitors. Finger authentication information refers to the fingerprint information (finger fingerprint image) of a specific finger on the hand if finger authentication device 4 is a fingerprint authentication device, and to the vein information (finger vein pattern image) of a specific finger on the hand if finger authentication device 4 is a finger vein authentication device.

[0019] Server 1 compares the fingerprint authentication information transmitted from fingerprint authentication device 4A or fingerprint authentication device 4B with the fingerprint authentication information stored in authentication DB 122. If they match, it determines that the person is an authorized visitor to enter power plant P and controls the gate 5A or 5B to open.

As shown in Figure 2, Server 1 is configured to include a control unit 11, a storage unit 12, and a communication unit 13, with each unit connected via a bus 14.

Camera 24 is, for example, a visible light camera. Camera 24 may generate color images using R (red), G (green), and B (blue) image sensors, or it may generate monochrome image data. Camera 24 functions as a reading means in cooperation with the control unit 21.

[0029] Speaker 25 outputs audio instructed by control unit 21.

[0034] The temperature detection unit 34 detects the temperature of a person passing in front of the finger authentication feasibility determination device 3 and outputs the detection result to the control unit 31.

[0035] Speaker 35 outputs audio instructed by control unit 31.

[0036] (Operation of the fingerprint authentication pre-approval system) Next, the operation of each device in the fingerprint authentication pre-approval / approval system 100 will be explained with reference to Figures 5 to 7.

[0037] First, let's explain the operation of induction device 2. Figure 5 is a flowchart showing the flow of the lane guidance process performed in the guidance device 2. The lane guidance process is performed in cooperation with the control unit 21 and the program 221 stored in the memory unit 22. For example, assuming that the camera 24 of the guidance device 2 is constantly taking pictures, the control unit 21 starts the lane guidance process when a person is recognized from the image acquired by the camera 24. The lane guidance process will now be explained with reference to Figure 5.

[0038] First, the control unit 21 causes the camera 24 to acquire an image of the access pass (step S1). As described above, visitors are required to possess an access pass. The control unit 21 outputs an audio guide, such as "Please hold your access pass in front of the camera," via the speaker 25, and causes the camera 24 to capture an image of the access pass. Alternatively, the guidance device 2 may be configured to include a display unit such as a monitor, and the through-image obtained by the camera 24 may be displayed on the display unit so that visitors can confirm whether or not their access pass is in a position where it can be photographed.

[0039] Next, the control unit 21 analyzes the acquired images and determines whether the person entering is a regular visitor or a temporary visitor (step S2). The control unit 21 analyzes the captured image and processes the recognition of identification information indicated on the access pass indicating whether the person is a regular visitor or a temporary visitor. Based on the recognition result, it determines whether the visitor is a regular visitor or a temporary visitor.

[0040] If the analysis determines that the person entering is a regular entrant (Step S3; YES), the control unit 21 guides the person to proceed to the regular entrant lane L1 (Step S4), and terminates the lane guidance process. For example, the control unit 21 outputs a voice message such as "Please proceed to the lane for permanent visitors" through the speaker 25. This allows visitors to be guided to the lane for permanent visitors L1.

[0041] If the analysis determines that the person entering is not a regular visitor (Step S3; NO), the control unit 21 determines whether the person entering is a temporary visitor or not (Step S5). If the control unit 21 determines that the person entering is a temporary visitor (step S5; YES), it guides the person to proceed to the temporary visitor lane L2 (step S6) and terminates the lane guidance process. For example, the control unit 21 outputs a voice message such as "Please proceed to the temporary access lane" through the speaker 25. This allows the person to be guided to the temporary access lane L2.

[0042] If it is not possible to determine whether the person entering is a permanent visitor or a temporary visitor (step S3; NO, step S5; NO), the control unit 21 outputs an error notification through the speaker 25 (step S7) and terminates the lane guidance process. For example, the control unit 21 outputs an error message via the speaker 25, such as, "Could not make a determination. Please hold the access card in front of the camera again."

[0043] Generally, access passes for permanent entrants have a photograph attached. Therefore, if the control unit 21 cannot determine from the captured image whether the entrant is a permanent entrant or a temporary entrant, it may extract the photograph from the access pass from the captured image, send the extracted photograph to the server 1, and request the server 1 to determine whether the entrant is a permanent entrant or not. The server 1 compares the facial image received from the guidance device 2 with the facial images of permanent entrants stored in the authentication information DB 122. If a matching facial image is found, it determines that the entrant is a permanent entrant; if no matching facial image is found, it determines that the entrant is a temporary entrant and sends the determination result to the guidance device 2. Since temporary entrants' access passes do not have photographs, if the control unit 21 cannot extract the facial image from the access pass from the captured image, it determines that the entrant is a temporary entrant. This minimizes errors and allows entrants to move smoothly to the appropriate lane.

[0044] Next, we will explain the operation of the finger authentication feasibility determination device 3. Figure 6 is a flowchart showing the flow of the finger authentication feasibility determination process performed in the finger authentication feasibility determination device 3. The finger authentication feasibility determination process is performed in cooperation with the control unit 31 and the program 321 stored in the storage unit 32. The control unit 31 starts the finger authentication feasibility determination process, for example, when infrared radiation due to human body temperature is detected by the temperature detection unit 34. The finger authentication feasibility determination process will now be described with reference to Figure 6.

[0045] First, the control unit 31 causes the temperature detection unit 34 to detect the temperature of the person (entrant) who comes in front of the finger authentication feasibility determination device 3, and obtains the temperature detection result (step S21). For example, the control unit 31 and the temperature detection unit 34 acquire a temperature distribution image of a person passing in front of the finger authentication feasibility determination device 3 and output it to the control unit 31. Alternatively, the finger authentication feasibility determination device 3 may be equipped with a platform or similar device on which the hand is placed within the detection range of the temperature detection unit 34, and the control unit 31 may output a voice prompting the user to place their hand on the platform via the speaker 35 to ensure reliable acquisition of the temperature of the fingers.

[0046] Next, the control unit 31 obtains the temperature of the visitor's fingertips based on the temperature detection result from the temperature detection unit 34 (step S22). For example, the control unit 31 recognizes the hand region from the acquired temperature distribution image and obtains the temperature of the fingers.

[0047] Next, the control unit 31 determines whether the temperature of the fingers is above a predetermined threshold (step S23). The specified threshold referred to here is the temperature value at which fingerprint authentication is possible, and below this temperature value, fingerprint authentication may fail. This value is determined experimentally or empirically.

[0048] If the control unit determines that the temperature of the fingers has not reached a predetermined threshold (step S23; NO), it determines that finger authentication is not possible, guides the person to warm their fingers before returning to the lane (step S24), and terminates the finger authentication feasibility determination process. For example, the control unit 31 outputs a voice message via the speaker 35 such as, "Finger authentication failed. Please warm your hands and return to the lane."

[0049] If the control unit 31 determines that the temperature of the fingers is above a predetermined threshold (step S23; YES), it determines that finger authentication is possible, guides the user to proceed to gate 5 (step S25), and terminates the finger authentication feasibility determination process. For example, the control unit 31 outputs voice messages such as "Please proceed to the gate" through the speaker 25.

[0050] Next, we will explain the operation of Server 1. Figure 7 is a flowchart showing the flow of the fingerprint authentication process performed on Server 1. The fingerprint authentication process is performed in cooperation with the control unit 11 and the program 121 stored in the storage unit 12. The control unit 11 starts the fingerprint authentication process when it receives fingerprint authentication information from the fingerprint authentication device 4 via the communication unit 13. The fingerprint authentication process will now be described with reference to Figure 7.

[0051] First, the control unit 11 compares the received finger authentication information with the finger authentication information stored in the authentication information DB 122 (step S31).

[0052] If the verification results show that the received finger authentication information matches any of the finger authentication information stored in the authentication information DB122 (step S32; YES), the control unit 11 determines that authentication is OK, sends an instruction to the gate 5 via the communication unit 13 to open the gate (step S33), and terminates the finger authentication process.

[0053] If the verification results in no match between the received fingerprint authentication information and any of the fingerprint authentication information stored in the authentication information DB122 (step S32; NO), the control unit 11 determines that authentication failed and sends a notification that entry is not permitted to the fingerprint authentication device 4, the source of the fingerprint authentication information, via the communication unit 13 (step S34), and terminates the fingerprint authentication process.

[0054] Thus, in the finger authentication pre-failure determination system 100, before finger authentication is performed upon entry, the temperature detection unit 34 of the finger authentication eligibility determination device 3 detects the temperature of the entrant's fingers. If the detected temperature does not reach a predetermined threshold, it is determined that finger authentication is not possible, and the entrant is guided to warm their fingers before undergoing finger authentication. Therefore, errors and re-authentication during finger authentication upon entry can be avoided, thereby alleviating congestion caused by waiting for finger authentication upon entry.

[0055] Furthermore, the passageway 10 leading to the entrance to the building of the power plant P is equipped with a lane L1 for permanent visitors, where fingerprint authentication is determined and performed for permanent visitors, and a lane L2 for temporary visitors, where fingerprint authentication is determined and performed for temporary visitors. The guidance device 2 installed at the branching point between these lanes determines whether a visitor is a permanent visitor or a temporary visitor, and guides visitors determined to be permanent visitors to the permanent visitor lane L1, and visitors determined to be temporary visitors to the temporary visitor lane L2. Therefore, waiting times for both permanent and temporary visitors can be reduced. In particular, waiting times can be significantly reduced for permanent visitors who are accustomed to fingerprint authentication and rarely experience authentication failures.

[0056] (modified version) In the above embodiment, the control unit 21 of the guidance device 2 analyzes the captured images acquired by the camera 24 to determine whether the person entering is a permanent entrant or a temporary entrant, and guides them to the lane using the speaker 25 based on the determination result. However, the above determination and guidance based on the determination result may be performed by the server 1. For example, the control unit 21 of the guidance device 2 transmits the captured image acquired by the camera 24 to the server 1 via the communication unit 23. The control unit 11 of the server 1 analyzes the captured image transmitted from the guidance device 2 to determine whether the person entering is a permanent visitor or a temporary visitor, and based on the determination result, transmits guidance information (lane information) to be output to the speaker 25 to the guidance device 2. Based on the guidance information transmitted from the server 1, the guidance device 2 outputs information about the lane the visitor should proceed in via the speaker 25.

[0057] Similarly, the control unit 31 of the finger authentication feasibility determination device 3 determines whether the temperature of the entrant's fingers is above a predetermined threshold based on the detection result from the temperature detection unit 34, and if it does not reach the predetermined threshold, it guides the entrant to warm their fingers before returning to the lane. However, the determination of whether the temperature of the entrant's fingers is above a predetermined threshold and the guidance based on the determination result may be performed by the server 1. For example, the control unit 31 of the finger authentication eligibility determination device 3 transmits the detection result obtained by the temperature detection unit 34 to the server 1 via the communication unit 33. The control unit 11 of the server 1 analyzes the received detection result to determine whether the temperature of the entrant's fingers is above a predetermined threshold, and based on the determination result, transmits guidance information to the finger authentication eligibility determination device 3 to be output to the speaker 35. Based on the guidance information transmitted from the server 1, the control unit 31 of the finger authentication eligibility determination device 3 outputs guidance information to the speaker 35 either prompting the entrant to warm their fingers before returning to the lane or prompting them to proceed directly to gate 5.

[0058] Furthermore, in the above embodiment, the camera 24 and the control unit 21 cooperate to realize the function of a reading means that reads identification information from the access pass indicating whether the person possessing the access pass is a permanent entrant or a temporary entrant to the power plant P. However, the reading means is not limited to this. For example, the access pass may be an IC card, and the above-mentioned identification information may be written on the IC card, and an IC card reader provided in the guidance device 2 may read the above-mentioned identification information as the reading means.

[0059] Furthermore, although the above embodiment described the case where the fingerprint authentication pre-approval system of the present invention is applied to entry into a power plant, the fingerprint authentication pre-approval system of the present invention can also be applied to entry into other places (including facilities, rooms, venues, etc.) besides power plants.

[0060] While embodiments of the present invention have been described and illustrated in detail above, the disclosed embodiments are illustrative and for illustrative purposes only, and are not limiting. The scope of the present invention should be interpreted in accordance with the appended claims. [Explanation of symbols]
