Description

[Technical field]

[0001] The present invention relates to a technique for transmitting information, and more particularly to a technique for confirming whether information has been transmitted. [Background technology]

[0002] At a construction site, the communication of safety-related information is important. Safety-related information is communicated, for example, through a document called a safety log. The safety log is prepared, for example, by an employee of the construction company who manages the construction site, and communicated to the person in charge of supervising the workers at the construction site.

[0003] The contents of the safety logbook need to be communicated reliably. However, it takes a lot of time to distribute documents to the people in charge of managing the workers at each location within the vast grounds of a construction site in person and to confirm whether they have read the information contained in the documents. Therefore, it is desirable to have a technology that can easily communicate the necessary information and confirm that the communication has been carried out. As a technology for communicating the necessary information and confirming that the communication has been carried out, for example, a technology such as that disclosed in Patent Document 1 has been disclosed.

[0004] The system in Patent Document 1 has a function of sending an inspection work report to a customer's mobile terminal device and receiving approval of the report via the mobile terminal device. In the system in Patent Document 1, approval is given when the customer presses an approval button on the display screen of the mobile terminal device. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2018-43836 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology of Patent Document 1 is insufficient in the following respects. In Patent Document 1, a report is sent to a mobile terminal device carried by a customer, and the report is considered to have been approved when an approval button is pressed. However, the technology of Patent Document 1 does not allow for confirmation that the customer to whom the report is to be transmitted has actually viewed the contents of the report. Therefore, the technology of Patent Document 1 is insufficient as a technology for confirming whether the person to whom information is to be transmitted has viewed the information.

[0007] SUMMARY OF THE PRESENT DISCLOSURE In order to solve the above problems, an object of the present invention is to provide an information management device and the like that can confirm whether a person to whom information is to be transmitted has viewed the information. [Means for solving the problem]

[0008] In order to solve the above problems, the information management device of the present invention includes an output unit and an authentication unit. The output unit outputs display data generated based on input data inputted in a first terminal device to a second terminal device. The authentication unit determines whether a user of the second terminal device when the second terminal device displays the display data matches a person specified in the input data by biometric authentication. Furthermore, when the user of the second terminal device matches a person specified in the input data as a transmission destination of the display data, the output unit outputs information indicating that the user of the second terminal device has confirmed the display data to the first terminal device.

[0009] The information management method of the present invention outputs display data generated based on input data inputted in a first terminal device to a second terminal device. The information management method of the present invention determines whether a user of the second terminal device when the second terminal device displays the display data matches a person specified in the input data by biometric authentication. Furthermore, the information management method of the present invention outputs information indicating that the user of the second terminal device has confirmed the display data to the first terminal device when the user of the second terminal device matches a person specified in the input data as a destination of the display data.

[0010] The information management program of the present invention causes a computer to execute a process of outputting display data generated based on input data inputted in a first terminal device to a second terminal device. The information management program of the present invention causes a computer to execute a process of determining, by biometric authentication, whether a user of a second terminal device when the second terminal device is displaying the display data matches a person specified in the input data. The information management program of the present invention also causes a computer to execute a process of outputting, to a first terminal device, information indicating that the user of the second terminal device has confirmed the display data when the user of the second terminal device matches a person specified in the input data as a destination of the display data. Effect of the Invention

[0011] According to the present invention, it is possible to confirm whether a person to whom information is to be transmitted has viewed the information. [Brief description of the drawings]

[0013] (First embodiment) A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing an outline of the configuration of an information management system of this embodiment. The information management system of this embodiment includes an information management device 10, a site management server 20, a first terminal device 30, and a second terminal device 40. The information management device 10 is connected to the site management server 20, the first terminal device 30, and the second terminal device 40 via a network.

[0014] The information management system of this embodiment is a system that manages the creation of a safety log, the transmission of the safety log, and confirmation of viewing of the safety log at a construction site. Since the work content at a construction site and the people working at the construction site change depending on the construction site and the work day, a safety log is created for each day work is performed. The safety log is created, for example, by an employee of a construction company that manages a construction site, and transmitted to a supervisor who supervises workers at the construction site. Transmission of the safety log to the supervisor at the construction site is recorded by information indicating that the supervisor at the construction site has confirmed the contents of the safety log. The supervisor who supervises workers at a construction site is also called a foreman.

[0015] A safety logbook is a document that contains information necessary to maintain safety at a construction site. For example, the safety logbook contains one or more of the following items: creator, safety goals, precautions to take at the construction site, work content, name of the work manager, number of workers, work precautions, information on dangerous work, qualification information, recipient, and person who checks the safety logbook. The safety logbook may contain items other than those listed above.

[0016] The following explanation will be given for the case where the safety log is created on a first terminal device 30, i.e., the items to be recorded in the safety log are entered, and the safety log is viewed on a second terminal device 40 used at the destination of the safety log.

[0017] The following describes the configuration of the information management device 10. Fig. 2 is a diagram showing an example of the configuration of the information management device 10. The information management device 10 includes a data acquisition unit 11, an authentication unit 12, a data extraction unit 13, a data generation unit 14, an output unit 15, and a storage unit 16.

[0018] The data acquisition unit 11 acquires image data of a facial photograph of a user of the first terminal device 30 from the first terminal device 30. In addition, the data acquisition unit 11 acquires image data of a facial photograph of a user of the second terminal device 40 from the second terminal device 40. The data acquisition unit 11 acquires input data input by user operation from the first terminal device 30 and the second terminal device 40. The data acquisition unit 11 acquires input data of items to be described in the safety log from the first terminal device 30. In addition, the data acquisition unit 11 acquires information indicating that the user has checked the safety log from the second terminal device 40.

[0019] The authentication unit 12 identifies the users of the first terminal device 30 and the second terminal device 40 by face authentication. The authentication unit 12 compares face photo data of the user of the first terminal device 30 acquired from the first terminal device 30 with face photo data acquired from the site management server 20, and identifies the users of the first terminal device 30 and the second terminal device 40 by well-known image authentication processing.

[0020] The authentication unit 12 compares the facial photo data of the user of the second terminal device 40 acquired from the second terminal device 40 with the facial photo data of the person specified in the safety log acquired from the site management server 20, and determines whether the persons match by a well-known image authentication process. The person specified in the safety log is a person who is written in the safety log as a recipient of the safety log. The person designated as a recipient of the safety log is, for example, a person in charge at the construction site.

[0021] The authentication unit 12 may identify the users of the first terminal device 30 and the second terminal device 40 using a biometric authentication technique other than face authentication. The authentication unit 12 may identify the users of the first terminal device 30 and the second terminal device 40 using vein authentication, iris authentication, fingerprint authentication, palm print authentication, voice print authentication or other biometric authentication techniques. The authentication unit 12 may also identify the users of the first terminal device 30 and the second terminal device 40 by combining a plurality of types of biometric authentication techniques. The authentication unit 12 may also identify the users using different types of biometric authentication techniques in the first terminal device 30 and the second terminal device 40. That is, the authentication unit 12 may identify the users using different types of biometric authentication techniques when creating the safety logbook and when confirming the viewing of the safety logbook. When using a biometric authentication technique other than face authentication, the data acquisition unit 11 acquires biometric data for biometric authentication according to the biometric authentication technique used.

[0022] The data extraction unit 13 acquires face photo data for face authentication and data for the safety log from the site management server 20. The data extraction unit 13 acquires, for example, detailed information of the worker as data for the safety log.

[0023] The data generating unit 14 generates display data for an input screen for the entry items in the safety logbook to be output to the first terminal device 30. The format of the safety logbook is preset, for example, for each construction site or each construction company that manages the construction site. The data generating unit 14 generates display data for the safety logbook to be output to the second terminal device 40 based on the input data acquired from the first terminal device 30 and the data acquired by the data extracting unit 13 from the site management server 20. In addition, when the selection of displaying detailed information is selected in the first terminal device 30 and the second terminal device 40 and input data is acquired via the data acquiring unit 11, the data generating unit 14 generates display data according to the input data.

[0024] The output unit 15 outputs the display data generated by the data generation unit 14 to either the first terminal device 30 or the second terminal device 40, whichever is the output destination terminal device.

[0025] The storage unit 16 stores data acquired from the site management server 20, the first terminal device 30, and the second terminal device 40. The storage unit 16 also stores data generated by the data generation unit .

[0026] The site management server 20 stores in a storage device information related to work on the construction site, detailed information on the manager and workers, and facial photo data of construction company employees, the manager and workers used for face authentication.

[0027] Information about work at a construction site includes, for example, the work schedule at the construction site, the company in charge of each process, the group in charge of each process, the names of the person in charge and workers for each process, information on qualified personnel, work records, and safety records. Information about work at a construction site may also include information on other items. Detailed information about the person in charge and workers includes, for example, the name of the company they belong to, the name of the group they belong to, the construction site they are in charge of, the process they are in charge of, the qualifications they hold, the date they entered, the time they entered, the number of days they worked, and the hours they worked. Detailed information about the person in charge and workers may also include information on items other than those listed above.

[0028] The configuration of the first terminal device 30 will be described. Fig. 3 is a diagram showing an example of the configuration of the first terminal device 30. The first terminal device 30 includes an image capturing unit 31, a communication unit 32, a display unit 33, and an operation unit 34. The first terminal device 30 includes a computer circuit including a processor and a memory (not shown). The processor executes a program stored in the memory, and controls the image capturing unit 31, the communication unit 32, the display unit 33, and the operation unit 34.

[0029] The photographing unit 31 photographs a face photograph of the user of the first terminal device 30. The photographing unit 31 is configured by, for example, a camera using a CMOS (Complementary Metal Oxide Semiconductor) image sensor. In addition, when the user of the first terminal device 30 is identified by biometric authentication other than face authentication, the first terminal device 30 further includes a function of acquiring biometric data used for biometric authentication. When the user of the first terminal device 30 is identified by biometric authentication other than face authentication, the first terminal device 30 may include a function of acquiring biometric data used for biometric authentication instead of the photographing unit 31.

[0030] The communication unit 32 communicates with the information management device 10 via the network.

[0031] The display unit 33 displays on a display device the display data acquired from the information management device 10. The display device may be formed as a device integrated with the first terminal device 30, or may be a device installed separately from the first terminal device 30.

[0032] The operation unit 34 accepts input from the user of the first terminal device 30 to the display screen displayed by the display unit 33 as input data. The operation unit 34 sends the accepted input data to the information management device 10 via the communication unit 32. For example, in a case where the display of more detailed information can be selected from the items displayed on the display screen, the operation unit 34 accepts data or commands related to the item selected by the user to be displayed as input data, and outputs the input data to the communication unit 32. The communication unit 32 sends the input data to the information management device 10. The operation unit 34 may be an input / output device integrated with the display unit 33, such as a touch panel type display device.

[0033] The configuration of the second terminal device 40 will be described. FIG. 4 is a diagram showing an example of the configuration of the second terminal device 40. The second terminal device 40 includes an image capturing unit 41, a communication unit 42, a display unit 43, and an operation unit 44. The configurations and functions of the image capturing unit 41, the communication unit 42, the display unit 43, and the operation unit 44 of the second terminal device 40 are similar to those of the first terminal device 30 with the same names. The second terminal device 40 also includes a computer circuit including a processor and memory (not shown). The processor executes a program stored in the memory to control the image capturing unit 41, the communication unit 42, the display unit 43, and the operation unit 44.

[0034] The information management device 10 and the first terminal device 30 may be integrated into one device. For example, a construction company employee may create a safety logbook by operating the information management device 10. The information management device 10 and the site management server 20 may be integrated into one device.

[0035] The operation of the information management system of this embodiment will be described below. Figures 5 and 6 are diagrams showing an example of the operation flow of the information management device 10 of this embodiment.

[0036] When input data for starting use of the first terminal device 30 is input to the operation unit 34 in response to an operation by the user, the photographing unit 31 of the first terminal device 30 takes a facial photograph of the user of the first terminal device 30. When the facial photograph of the user is taken, the photographing unit 31 generates image data of the facial photograph. When the image data of the facial photograph is generated, the communication unit 32 sends the image data of the facial photograph to the information management device 10.

[0037] 5, the data acquisition unit 11 of the information management device 10 acquires image data of a facial photograph of a user of the first terminal device 30 from the first terminal device 30 (step S11). When the image data of the facial photograph of the user of the first terminal device 30 is acquired, the authentication unit 12 identifies the user of the first terminal device 30 (step S12). The authentication unit 22 compares the image data of the user's facial photograph acquired from the first terminal device 30 with the image data acquired from the site management server 20, and identifies the user of the first terminal device 30 by a well-known image authentication process.

[0038] When the user of the first terminal device 30 is identified, the data extraction unit 13 acquires information corresponding to the identified user from the site management server 20 (step S13). The data extraction unit 13 acquires, for example, information on input items of a safety logbook corresponding to a construction site in charge of the identified user from the site management server 20.

[0039] When the information corresponding to the user is acquired, the data extraction unit 13 generates data for an input screen for the safety log (step S14). When the data for the input screen for the safety log is generated, the output unit 15 outputs the data for the input screen for the safety log to the first terminal device 30 (step S15).

[0040] The communication unit 32 of the first terminal device 30 acquires data for the input screen of the safety log from the information management device 10 via the network. When the data for the safety log is acquired, the display unit 33 displays the data for the input screen of the safety log on the display device.

[0041] FIG. 7 is a diagram showing an example of an input screen for a safety log. The input screen in FIG. 7 shows the date of the day covered by the safety log, the name of the construction site, the work area, the name of the creator of the safety log, and the name of the person in charge to whom the log is to be transmitted. In addition, in the safety log of FIG. 7, safety goals, safety instructions, and workers are set as input items. The input screen for the safety log may include items other than those mentioned above. In the safety log of FIG. 7, information on whether or not the person in charge to whom the safety log is to be transmitted has confirmed the log is displayed. In the safety log of FIG. 7, since the log is in the creation stage, information on whether or not the person in charge to whom the log is to be transmitted has confirmed the log is displayed as "unapproved," which indicates that the person in charge has not confirmed the log. In addition, in the input screen of FIG. 7, each item may be input by selecting from a pull-down menu.

[0042] The operation unit 34 accepts, as input data, an input from the user of the first terminal device 30 to the display screen displayed by the display unit 33. The operation unit 34 sends the accepted input data to the information management device 10 via the communication unit 32.

[0043] The data acquisition unit 11 of the information management device 10 acquires input data for the safety log from the first terminal device 30 via the network. The data extraction unit 13 acquires data corresponding to the input data from the site management server 20. The data extraction unit 13 acquires, for example, information on workers supervised by the person in charge set in FIG. 7 from the site management server 20.

[0044] When the information corresponding to the input data is acquired, the data generating unit 14 stores the acquired input data in the storage unit 16 in association with the data on the input screen of the safety log.

[0045] When input data for starting viewing the safety log on the second terminal device 40 is input into the operation unit 44 in response to operation by the user, the display unit 43 sends a request for the safety log data to the information management device 10 via the communication unit 42.

[0046] The data acquisition unit 11 of the information management device 10 receives a request for the safety logbook data from the second terminal device 40. Upon receiving the request for the safety logbook data, the data generation unit 14 generates display data for the safety logbook.

[0047] When the display data of the safety log is generated, in FIG. 6, the output unit 15 outputs data of the input screen for the safety log to the second terminal device 40 (step S21).

[0048] The communication unit 42 of the second terminal device 40 acquires display data for the safety log from the information management device 10 via the network. When the display data for the safety log is acquired, the display unit 43 displays the safety log on the display device.

[0049] Fig. 8 is a diagram showing an example of display data of the safety log. Data including the safety goal, safety instruction contents, and workers inputted to the input screen of Fig. 7 is displayed as the display data of the safety log.

[0050] When the safety log data is displayed, the photographing unit 41 photographs a face photograph of the user of the second terminal device 40, i.e., the person viewing the safety log data on the second terminal device 40. When the face photograph of the user is photographed, the photographing unit 41 generates image data of the face photograph. When the image data of the face photograph is generated, the communication unit 42 sends the image data of the face photograph to the information management device 10.

[0051] The data acquisition unit 11 of the information management device 10 acquires image data of a facial photograph of the user of the second terminal device 40 from the second terminal device 40 (step S22). When the image data of the facial photograph of the user of the second terminal device 40 is acquired, the authentication unit 12 compares the image data of the facial photograph of the user acquired from the second terminal device 40 with the image data acquired from the site management server 20, and identifies the user by a well-known image authentication process (step S23).

[0052] When the user of the second terminal device 40 is identified, the authentication unit 12 judges whether or not the user of the second terminal device 40 matches the approver of the safety logbook. When the user of the second terminal device 40 matches the approver of the safety logbook, the authentication unit 12 determines that the user of the second terminal device 40, who is the person specified in the safety logbook, has checked the safety logbook (step S24). When it is determined that the safety logbook has been checked, the data generation unit 14 records that safety has been checked, and saves the date and time when it was checked in the storage unit 16 (step S25).

[0053] When the data generating unit 14 records that safety has been confirmed, the output unit 15 adds information indicating that the safety log has been confirmed to the data of the safety log, and outputs the data to the first terminal device 30 (step S26).

[0054] The communication unit 32 of the first terminal device 30 acquires the safety log data from the information management device 10 via the network. When the safety log data is acquired, the display unit 33 displays the safety log data indicating that it has been confirmed on the display device.

[0055] Fig. 9 is a diagram showing an example of display data of a safety log showing that it has been confirmed. In Fig. 9, it is assumed that the person in charge who viewed the safety log in Fig. 8 has confirmed the contents, and information showing the date and time when the contents were confirmed and that they have been confirmed is displayed.

[0056] It may be recorded by image authentication whether a worker shown in the safety logbook in Fig. 8 is actually present at the construction site. Fig. 10 is a diagram showing an example of a display screen when recording by image authentication whether a worker shown in the safety logbook is actually present at the construction site. When the worker's field is selected by the user of the second terminal device 40 on the display screen in Fig. 8, the operation unit 44 accepts the user's selection as input data. When the selection is input, the display unit 43 displays a photographed screen of the worker.

[0057] FIG. 10 is a diagram showing an example of a photographing screen. In the example of FIG. 10, a photographing button and a list of workers are displayed. When the person in charge photographs a worker using the second terminal device 40, the photographing unit 41 generates image data of the worker and sends the generated image data to the information management device 10 via the communication unit 42. The authentication unit 12 of the information management device 10 identifies the person in the image data. When the identified person is a worker described in the safety logbook, the data generation unit 14 records the identified worker as having been confirmed, and stores the date and time of confirmation in the storage unit 16. In the example of FIG. 10, information that has been confirmed for workers C and D is sent to the second terminal device 40 and reflected on the display screen as the confirmation date and time.

[0058] Further, more detailed information may be displayed on the display screen as shown in FIG. 8. FIG. 11 is a diagram showing an example of detailed information displayed when selecting work on the display screen of the safety log in FIG. 8. When the user of the second terminal device 40 selects the work instruction content on the display screen of FIG. 8, the operation unit 44 accepts the selection result by the user as input data. When the selection result is input, the communication unit 42 transmits the input data to the information management device 10. When the data generation unit 14 of the information management device 10 receives the information of the selection result via the data acquisition unit 11, it generates display data of the detailed information and transmits the display data to the second terminal device 40 via the output unit 15. When the display unit 43 of the second terminal device 40 receives the display data via the communication unit 42, it displays detailed information of the work instruction content on the screen. In FIG. 11, safety confirmation items necessary for scaffolding assembly work are displayed.

[0059] In the example of FIG. 10, an example of checking the presence or absence of a worker has been described, but in the example of FIG. 11, image authentication may be used to check that a safety check item is being performed using image data of the worker and that a qualified worker is actually present at the construction site. For example, when the safety check item specifies the worker's clothing or equipment, the authentication unit 12 of the information management device 10 identifies whether the worker is wearing the specified clothing or equipment by image authentication based on image data of the worker's whole body taken by the second terminal device 40. The authentication unit 12 compares the characteristics of the specified clothing or equipment with the characteristics of the image data of the worker's whole body photo, and determines that the worker is wearing the specified clothing or equipment when the degree of match of the characteristics is equal to or greater than a preset standard.

[0060] In the case of a configuration in which the presence or absence of a worker, the presence or absence of a qualified person, the presence or absence of a designated clothing, or the presence or absence of a designated equipment is confirmed, the information management device 10 may send a notification to one or both of the first terminal device 30 and the second terminal device 40 when there is an item that has not been confirmed. By adopting such a configuration, it is possible to more reliably confirm the items that need to be confirmed. In addition, the information management device 10 may store the confirmation result of the presence or absence of a person who needs to be confirmed as statistical data, and periodically send a notification to one or both of the first terminal device 30 and the second terminal device 40. By adopting such a configuration, the users of the first terminal device 30 and the second terminal device 40 can obtain information indicating whether the contents specified in the safety log are being observed at the construction site.

[0061] In the above example, the transmission of the safety log at a construction site has been described, but the information management system of this embodiment may be used to transmit safety information at places other than construction sites. The information management system of this embodiment may also be used to transmit documents other than the safety log and to check whether the documents have been viewed. The information management system of this embodiment can be used to transmit documents such as caution notes, instructions, circulars, warning letters, situation explanation documents or reports, and to check whether the documents have been viewed. The application of the information management system of this embodiment is not limited to the above example, as long as it requires the transmission of documents and the confirmation of whether the documents have been viewed.

[0062] In the information management system of this embodiment, the information management device 10 outputs display data of the safety journal generated based on input data inputted via the first terminal device 30 to the second terminal device 40. The information management device 10 acquires image data of the user of the second terminal device 40 when the second terminal device 40 displays the display data of the safety journal, and determines whether the person specified in the input data matches the user of the second terminal device 40 by image authentication. That is, the information management device 10 can determine whether the person specified in the safety journal actually views the safety journal. With this configuration, the information management system of this embodiment can record whether the user of the second terminal device 40 has checked the safety journal while transmitting information of the safety journal to the second terminal device 40. As a result, the information management system of this embodiment can transmit information to a person in a remote location and confirm whether the person to whom the information is transmitted has viewed the information.

[0063] Second Embodiment The second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 12 is a diagram showing an outline of the configuration of the information management device of this embodiment. The information management device 100 of this embodiment includes an output unit 101 and an authentication unit 102. The output unit 101 outputs display data generated based on input data inputted in the first terminal device to the second terminal device.
