The display D is connected to the information management apparatus 101 via a terminal and cable conforming to standards such as HDMI (High-Definition Multimedia Interface: registered trademark), DisplayPort, and D-Sub.

Note that the output means is not limited to the display D as long as it is a device or device that outputs information to be managed. The output unit may be, for example, a printing device that prints the managed information in response to a request from the information management device 101 .

The camera C is a device that captures an image in a predetermined imaging range IR and generates imaging data representing the captured image. The camera C is connected to the information management apparatus 101 via a terminal and cable conforming to standards such as USB (Universal Serial Bus), for example.

The camera C includes an imaging range IR that includes a range in which the management target information MO1 displayed on the display D is visible. Thereby, the camera C captures an image of the viewer V1 (for example, the face of the viewer V1) of the management target information MO1 displayed on the display D, as shown in FIG. Such a camera C is an example of imaging means for imaging the viewer V1.

In the present embodiment, an example in which the imaging data is data representing a moving image will be described, but it may be data representing a still image. good too.

Note that FIG. 1 shows an example in which the camera C as the imaging means is attached above the display D, but the location where the imaging means is installed is not limited to this. The imaging means only needs to include the visible range of the managed information MO1 displayed on the display D in the imaging range IR, and the information management device 101 can acquire the imaging data. The imaging means may be built in the information management device 101 or the output means, for example, or may be a monitoring camera attached to the room installed in the information management device 101, or the like.

The information management device 101 is a device that manages management target information based on image data generated by the camera C. FIG.

For example, the information management device 101 generates a viewing log. Further, the information management apparatus 101 determines whether or not the viewer V1 included in the imaging data is a registrant, and performs various functions such as controlling the output of the management target information MO1 to the display D according to the determination result. process.

Here, the viewing log is data indicating the history of viewing of the managed information MO1.

A registrant is a person who has the authority to browse the managed information MO1, and is registered in the information management apparatus 101, for example, by a company that manages the managed information MO1, which is determined for each piece of managed information. .

The server device 102 is a personal computer, a general-purpose computer, or the like connected to the information management device 101 via the network N so as to be able to communicate with each other.

The network N is a network constructed by a line that is wired, wireless, or an appropriate combination thereof. The network N includes, for example, a part or all of networks called LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network), the Internet, and the like.

(Functional Configuration of Information Management Device 101)
As shown in FIG. 2, the information management apparatus 101 functionally includes an output control unit 110, an imaging data acquisition unit 111, a history image generation unit 112, a history image storage unit 113, and a management information storage unit 114. , a determination unit 115 , a log storage unit 116 , a log generation unit 117 , an instruction reception unit 118 , a registration management unit 119 , a log transmission unit 120 , and a log search unit 121 .

The output control unit 110 controls display of the management target information MO1 on the display D. FIG.

For example, when the managed information MO1 is output to the display D, the display D can display the managed information MO1. cannot be displayed. Therefore, the output control unit 110 can control display and non-display of the management target information on the display D by controlling whether or not to output the management target information MO1 to the display D, for example.

Specifically, for example, the managed information MO1 is stored in the management information storage unit 114 . The output control unit 110 acquires the managed object information MO1 from the managed information storage unit 114 based on the managed object ID (identifier) specified by the user. When the output control unit 110 outputs the acquired managed information MO1 to the display D, the managed information MO1 is displayed on the display D. FIG.

Note that the output control unit 110 may shut down the information management apparatus 101 when an unregistered person for the managed information MO1 being displayed on the display D is included in the imaging data. This can also stop the display of the managed information MO1.

The imaging data acquisition unit 111 acquires imaging data generated by the camera C. FIG.

For example, the captured data acquisition unit 111 acquires captured data representing an image captured by the camera C when the management target information MO1 is displayed on the display D from the camera C in real time. As a result, the imaging data acquisition unit 111 acquires imaging data including the viewer V1 of the management target information MO1 in real time.

The history image generator 112 generates history image data.

The history image data is data that includes the management target information MO1 and the imaging data that are displayed by the display D and captured by the camera C at the same time, respectively, in association with each other. The history image data may further be associated with time information indicating the date and time corresponding to the display and image capturing times of the display D and the camera C, respectively.

Specifically, for example, the history image generation unit 112 acquires image data including the management target information MO1 from the output control unit 110 in real time. Also, the history image generation unit 112 acquires the captured data from the captured data acquisition unit 111 in real time. The history image generator 112 associates the image data acquired at the same time with the imaging data. Then, the history image generation unit 112 generates history image data by further associating time information indicating the date and time when the image data and the captured data were acquired.

The management target information MO1 included in the history image data may be included in the image data showing temporally continuous images showing only the management target information MO1 displayed on the display D, or may be an image of the entire screen of the display D. may be included in the image data that temporally continuously represents the .

Note that the image data included in the history image data may be a still image. Also, the image data may be an image showing a screen snapshot of the display D. FIG. A screen snapshot is an image showing the display state of the display D, and is also generally called a screen shot, a screen capture, or the like.

The history image storage unit 113 is a storage unit that stores history image data. The history image data is stored in the history image storage unit 113 by the history image generation unit 112 .

The management information storage unit 114 is a storage unit that stores information regarding the management target information MO1.

Specifically, for example, the management information storage unit 114 stores management target information MO1, registration data 122, and employee data 123. FIG.

The registration data 122 is data in which a registrant who has viewing authority for the managed information MO1 is registered. As an example is shown in FIG. 3, in the registration data 122a, the managed object ID and the registrant ID are associated with each other. The registration data 122a and each of the registration data 122b to 122c exemplified below are examples of the registration data 122, and the registration data 122 is a general term when the registration data 122a to 122c are not particularly distinguished.

The registrant ID is information for identifying the registrant of the managed information MO1 identified by the associated managed object ID. The registrant ID according to this embodiment is the employee ID of the registrant.

An employee ID is information for identifying each employee in a company that manages managed information in the present embodiment.

Note that the registrant ID may be a unique number or combination of alphabets for the registrant, a face image of the registrant, information indicating characteristics of the face image of the registrant, or the name of the registrant.

The registration data 122a illustrated in FIG. 3 includes two managed object IDs "M1" and "M2."

The managed object ID "M1" is information for identifying the managed object information MO1, and two registrant IDs "V1" and "V3" are associated with the managed object ID "M1". That is, the employees identified by "V1" and "V3" are registered as registrants for the managed information MO1.

One registrant ID "V2" is associated with the managed ID "M2". That is, the employee identified by "V2" is registered as a registrant for the managed information identified by the managed ID "M2".

The employee data 123 is data for managing employees of a company that manages managed information. As an example is shown in FIG. 4, in the employee data 123, the above-mentioned employee ID, affiliation information, face information, and name are associated.

The affiliation information is information indicating an organizational unit (so-called department, section, etc.) in the company that manages the managed information MO1 in the present embodiment, and is the organization to which the employee identified by the associated employee ID belongs. Indicates units.

The face information is information for identifying the face of the employee identified by the associated employee ID, and is, for example, information indicating a face image, information indicating features of the face image, and the like.

Note that in the present embodiment, the registration data 122 and the employee data 123 associate the managed information with the registrant's face information. Instead of the employee ID of the registrant, face information of the registrant may be employed as the registrant ID of the registration data 122. In this case, the employee data 123 does not need to be stored in the management information storage unit 114. good.

A determination unit 115 acquires a viewer based on the imaging data. The determination unit 115 determines whether or not the acquired viewer is a registrant. This registrant is identified in the registration data 122 by the registrant ID associated with the managed information MO1 displayed on the display D when the imaging data is acquired.

The timing for determination by the determination unit 115 is, for example, when the management target information MO1 is started to be displayed on the display D, or when there is a change in the viewer V1 included in the imaging data.

The log storage unit 116 is a storage unit that stores browsing logs.

The log generation unit 117 generates a viewing log in which the viewer information is associated with the management target information MO1 displayed on the display D when imaging data including the viewer identified by the viewer information is acquired.

The viewer information is information for identifying the viewer. The viewer information according to the present embodiment is information for identifying a viewer obtained based on the imaging data (that is, the viewer 9 included in the imaging data. In the present embodiment, the viewer information is , is the employee ID of the viewer.

It should be noted that the viewer information is preferably defined so that it can be determined when the viewer identified by the viewer information and the registrant identified by the registrant ID are the same person. For example, the viewer information includes a combination of numbers and alphabets unique to each person that are used in common with the registrant ID, the facial image of the viewer, information indicating the characteristics of the facial image of the viewer, the name of the viewer, and the like. may

Instruction accepting unit 118 determines whether or not an instruction from the user has been accepted.

Instructions received by the instruction receiving unit 118 are, for example, a start instruction, an end instruction, a cancellation instruction, and a setting instruction.

The start instruction is an instruction to start the process for displaying on the display D the managed object information MO1 identified by the managed object ID, including the managed object ID. The end instruction is an instruction to end the process for displaying the managed information MO1 on the display D started based on the start instruction.

The cancellation instruction is an instruction for canceling the suspension of the display of the managed information MO1 on the display D when the display of the managed information MO1 on the display D is suspended by the output control unit 110 . The setting instruction is an instruction for registering the viewer included in the imaging data acquired by the imaging data acquisition unit 111 as a registrant in the registration data 122 for the management target information MO1 related to the start instruction.

Registration management unit 119 registers a registrant in registration data 122 . The registration management unit 119 includes, as shown in FIG. 5, a registration setting unit 119a and a registration update unit 119b.

Upon receiving a setting instruction, the registration setting unit 119a registers, in the registration data 122, the viewer included in the imaging data acquired when the setting instruction is received as a registrant of the management target information.

When the instruction receiving unit 118 receives the cancellation instruction, the registration updating unit 119b updates the unregistered person included in the imaging data when the display of the management object information related to the cancellation instruction is stopped to the management object information. Register in the registration data 122 as a registrant for MO1.

Again, refer to FIG.
Log transmission unit 120 transmits the browsing log to server device 102 as a predetermined device.

The log search unit 121 performs processing for searching for a viewer of the managed information MO1 based on the viewing log.

(Physical Configuration of Information Management Device 101)
From here, the physical configuration of the information management device 101 will be described.
The information management device 101 physically has a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input/output interface 1050, and a network interface 1060, as shown in FIG. Such an information management apparatus 101 is, for example, a personal computer, a tablet terminal, or the like.

A bus 1010 is a data transmission path through which the processor 1020, the memory 1030, the storage device 1040, the input/output interface 1050, and the network interface 1060 mutually transmit and receive data. However, the method of connecting processors 1020 and the like to each other is not limited to bus connection.

The processor 1020 is a processor realized by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

The memory 1030 is a main memory implemented by RAM (Random Access Memory) or the like.

The storage device 1040 is an auxiliary storage device such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), a memory card, or a ROM (Read Only Memory). The storage device 1040 implements the functions of the storage units of the information management apparatus 101 (for example, the history image storage unit 113, the management information storage unit 114, and the log storage unit 116). In addition, the storage device 1040 performs each function of the information management apparatus 101 (for example, the output control unit 110, the imaging data acquisition unit 111, the history image generation unit 112, the determination unit 115, the log generation unit 117, the instruction reception unit 118, the registration management 119, log transmission unit 120, and log search unit 121). Each function corresponding to the program module is realized by the processor 1020 reading each program module into the memory 1030 and executing it.

The input/output interface 1050 is an interface for connecting the information management apparatus 101 and various input/output devices (for example, camera C, display D, input unit 1070). The input unit 1070 is a device for user input, and includes, for example, a keyboard, a mouse, and a touch sensor provided on the display screen of the display D. FIG.

A network interface 1060 is an interface for connecting the information management apparatus 101 to the network N. FIG. A printing device (not shown) may be connected via the input/output interface 1050 or the network interface 1060 .

The physical configuration of the server device 102 is also the same as the physical configuration of the information management device 101 shown in FIG.

From here, the operation of the information management apparatus 101 according to this embodiment will be described with reference to the drawings.

(Information management processing)
7 and 9 are flowcharts showing an example of information management processing according to Embodiment 1 of the present invention. The information management process is started, for example, when a start instruction is received by the instruction receiving unit 118 . The start instruction includes the managed ID as described above.

An example in which a start instruction related to the managed information MO1 is accepted, that is, an example in which the accepted start instruction includes the managed object ID "M1" corresponding to the managed information MO1 will be described below. An example in which the registration data 122a shown in FIG. 3 is stored in the management information storage unit 114 at the start of the information management processing will be described.

Please refer to FIG.
The determination unit 115 determines whether or not the registration data 122a includes a registrant associated with the managed information MO1 related to the start instruction (step S101).

For example, the registration data 122a has a registrant ID associated with the managed ID "M1". Therefore, the determination unit 115 determines that the registrant is in the registration data 122a.

Again, refer to FIG.
When it is determined that a registrant exists in the registration data 122 (step S101; Yes), the determination unit 115 determines whether or not all viewers included in the imaging data are registrants (step S102). Here, the fact that all viewers are registrants means that the viewers do not include non-registrants.

Specifically, for example, the determination unit 115 refers to the latest image data among the image data acquired in real time by the image data acquisition unit 111 after receiving the start instruction. Then, the determination unit 115 determines that the human face included in the referenced imaging data is the face of the viewer V1, and extracts the face information of the viewer V1. As a result, the face information of the viewer V1 of the managed information MO1 related to the start instruction can be obtained based on the imaging data.

In the process of extracting the viewer V1 from the imaging data, it is preferable to employ conventional image processing techniques using pattern matching, machine learning, and the like. Further, when extracting the viewer V1 from the imaging data, the face orientation is used to determine whether the viewer V1 is within a predetermined range from the display D and whether the line of sight is directed toward the display D. is within a predetermined range may be adopted as a face extraction condition.

Then, the determination unit 115 acquires the face information of the registrants V1 and V3 associated with the management target ID related to the start instruction in the registration data 122 and the employee data 123 .

Based on the face information of the registrants V1 and V3 acquired based on the registration data 122 and the face information of the viewer V1 extracted from the imaging data, the determination unit 115 determines whether or not all of the viewer V1 is a registrant. determine whether Conventional image processing techniques using pattern matching, machine learning, etc. may be employed in the process of determining whether or not all viewers V1 are registrants.

The determination processing (step S102) by the determination unit 115 is sequentially performed substantially in real time based on the imaging data acquired by the imaging data acquisition unit 111 in real time.

Note that the determination processing (step S102) described here is an example, and may be changed as appropriate.

For example, as shown in FIG. 1, it is assumed that the viewer at the start of the information management process MO1 is only the viewer V1. In the registration data 122a, the registrant ID associated with the managed ID "M1" includes "V1" corresponding to the viewer V1. In this case, the determination unit 115 determines in step S102 that all viewers V1 are registrants (that is, viewers V1 do not include unregistered users).

If all viewers are determined to be registrants (step S102; Yes), the output control unit 110 acquires the managed information MO1 related to the start instruction from the management information storage unit 114, and outputs it to the display D. . As a result, the output control unit 110 causes the display D to display the managed information MO1 (step S103).

The log generation unit 117 generates a viewing log regarding viewing of the managed information MO1 from the reception of the start instruction to the present (step S104).

An example of the browsing log 116a created here is shown in FIG.

As shown in the figure, the browsing log 116a includes the managed object ID "M1" of the managed information MO1 related to the start instruction and the user ID "V1" for identifying the user. A user ID according to this embodiment is an employee ID of a user of the information management device 101 .

The viewing log 116a also includes information about the start instruction. In the information about the start instruction, the date and time when the start instruction was accepted, the viewer information of the viewer included in the imaging data acquired at that time, and the determination result of the determination unit 115 regarding the viewer are associated.

Furthermore, the browsing log 116a includes information about the start of browsing. In the information about the start of browsing, the date and time when browsing started is associated with the history image ID.

Since the viewing start date and time is, for example, substantially the same as the date and time when the managed information MO1 started to be output from the output control unit 110 to the display D, it is preferable to adopt this date and time as the viewing start date and time.

The history image ID is information for identifying the history image data, and indicates, for example, the storage location in the history image storage unit 113, the file name of the history image data, and the like.

The history image ID associated with the viewing start date and time is information for identifying history image data generated by the history image generation unit 112 from the viewing start date and time.

The instruction receiving unit 118 determines whether or not an end instruction has been received (step S105).

When it is determined that the end instruction has not been received (step S105; No), the determination unit 115 determines whether or not there is a change in the viewer included in the imaging data (step S106).

If it is determined that there is no change in the viewer (step S106; No), the process of step S105 is performed again.

Here, it is assumed that the viewer changes from the state shown in FIG. 1 to the state shown in FIG. 10(a). In FIG. 10(a), a viewer V2 whose employee ID is "V2" joins the viewer V1 shown in FIG. In such a case, since the viewer V2 is added to the viewers included in the imaging data, the determination unit 115 determines that there is a change in the viewers.

Again, refer to FIG.
If it is determined that there is a change in the viewers (step S106; Yes), the determining unit 115 determines that all of the viewers after the change are registrants (that is, the viewers after the change include non-registrants). or not) (step S107).

The determination process in step S107 is preferably performed in substantially the same manner as the determination process in step S102. For example, the determination unit 115 extracts the face information of the viewers V1 and V2 from the latest image data among the image data acquired in real time by the image data acquisition unit 111 while the management target information MO1 is being displayed. Then, the determination unit 115 acquires the face information of the registrants V1 and V3 associated with the management target ID related to the start instruction in the registration data 122 and the employee data 123 . Based on the face information of registrants V1 and V3 and the face information of viewers V1 and V2, determination unit 115 determines whether or not all viewers V1 after change are registrants.

For example, in the registration data 122a shown in FIG. 3, the registrant IDs associated with the managed object ID "M1" related to the start instruction are "V1" and "V3", and the viewer V2 is an unregistered person. Since the unregistered person V2 is included in the viewers V1 and V2 after the change, the determining unit 115 determines that none of the viewers V1 and V2 after the change are registrants (that is, the viewers V1 and V2 are non-registrants). registrant V2 is included).

Again, refer to FIG.
If it is determined that all the viewers after the change are not registrants (step S107; No), the output control unit 110 stops outputting the managed information MO1 related to the start instruction to the display D. As a result, the output control unit 110 stops displaying the managed information MO1 on the display D (step S108).

Again, refer to FIG.
If it is determined that the end instruction has been received (step S105; Yes), the log generation unit 117 generates a viewing log (step S113) and ends the information management process. FIG. 13 shows an example of the browsing log 116c generated in step S113.

In the browsing log 116c shown in FIG. 13, as indicated by the dotted line, the browsing end date and time are added to the browsing log 116a shown in FIG. The viewing end date and time is the date and time at which viewing of the managed information MO1 related to the start instruction ends, and the date and time at which the end instruction is received, for example, is adopted as the viewing end date and time.

Even if it is determined that the cancellation instruction has not been received (step S109 in FIG. 8; No), the log generation unit 117 generates a viewing log to which the viewing end date and time is added as shown in FIG. 7 (step S113). ) to end the information management process.

Again, refer to FIG.
If it is determined in step S107 that all the viewers are registrants (step S107; Yes), the output control unit 110 continues to manage the managed information MO1 on the display D without stopping the display. The target information MO1 is displayed (step S103). Then, the log generation unit 117 generates a viewing log (step S104). Further, when the end instruction is accepted (step S105; Yes), the log generation unit 117 generates a viewing log (step S113). FIG. 14 shows an example of the browsing log 116d generated in steps S104 and S113.

The browsing log 116d shown in FIG. 14 is similar to the browsing log 116b shown in FIG. 12 in that it is a browsing log after the number of browsing users V2 increases as shown in FIG. 10A. is.

The browsing log 116d shown in FIG. 14 is an example of a browsing log when the registrant IDs "V1" and "V2" are registered in association with the managed ID "M1" in the registration data 122b before the number of visitors V2 increases. is. In other words, the viewing log 116d is an example of a viewing log when the managed information MO1 is continuously output to the display D even after the viewer changes.

In the browsing log 116d shown in FIG. 14, information surrounded by a dotted line is added to the browsing log 116a shown in FIG. The added information is described here.

Viewing log 116d includes information about changes in viewers when output continues. This information is generated in step S104.

The information about the change of the viewer included in the viewing log 116d includes the date and time when the viewer changed, whether or not the display in the managed information MO1 was stopped due to the change of the viewer, the viewer information of the viewer after the change, and the history. and an image ID. The changed viewer information of the viewer is associated with the result of determination by the determining unit 115 as to whether or not the viewer is a registrant.

The history image ID associated with the viewer change date and time is information for identifying history image data generated by the history image generator 112 from the viewer change date and time.

The viewing log 116d also includes the viewing end date and time generated in step S113.

Again, refer to FIG.
When it is determined that there is no registrant in the registration data 122 (step S101; No), the instruction receiving unit 118 determines whether or not a setting instruction has been received (step S111). A typical example in which there is no registrant in the registration data 122 is when management target information is created for the first time.

If it is determined that none of the viewers are registered users (that is, the viewers include non-registered users) (step S102; No), the instruction receiving unit 118 also executes the process of step S111. .

When determining that the setting instruction has not been received (step S111; No), the instruction receiving unit 118 terminates the information management process.

If the setting instruction is accepted (step S111; Yes), the registration setting unit 119a registers the viewer included in the imaging data acquired when the setting instruction is accepted in the management target information MO1 related to the start instruction. The user is registered in the registration data 122a as a person (step S112). Then, the processes after step S103 are executed.

So far, the information management processing according to the present embodiment has been described.

According to the information management processing according to the present embodiment, it is possible to generate a viewing log for each managed information.

The log search unit 121 determines whether or not a search instruction has been received based on whether or not the search button 130d has been pressed by the user (step S202).

If it is determined that the search instruction has not been received (step S202; No), the log search unit 121 determines whether or not the search end instruction has been received based on whether the end button 130e has been pressed by the user. (Step S203).

If it is determined that the search end instruction has been received (step S203; Yes), the log search unit 121 ends the search process. If it is determined that the search end instruction has not been received (step S203; No), the log search unit 121 continues the search instruction determination process (step S202).

Thereby, the user can input search conditions on the search screen 130 until the user issues a search instruction or a search end instruction.

If it is determined that the search instruction has been received (step S202; Yes), the log search unit 121 displays the search result of the browsing log on the display D based on the search conditions input to the search screen 130 displayed in step S201. is displayed (step S204).

Specifically, the log search unit 121 acquires from the log storage unit 116 the browsing log that satisfies the search conditions input to the search screen 130 displayed in step S201. Then, the acquired browsing log is displayed on the display D as a search result.

In the search screen 130 illustrated in FIG. 16, the managed object ID of the managed object information MO1 is entered in the first input field 130a. No information has been entered in the second entry field 130b. Information for identifying the A part is entered in the third entry field 130c.

In this case, the log search unit 121 causes the display D to display the browsing log 116c or 116d including the information of the browsing person who has the management target ID "M1" and belongs to "A section" as the search result. The log search unit 121 may refer to the employee data 123 as necessary.

Again, refer to FIG.
The log search unit 121 determines whether or not a search end instruction has been received based on whether or not the end button 130e has been pressed by the user (step S205).

If it is determined that the search end instruction has been received (step S205; Yes), the log search unit 121 ends the search process. If it is determined that the search end instruction has not been received (step S205; No), the log search unit 121 keeps the display D displaying the search results. Thereby, the user can refer to the search result on the display D. FIG. Note that the log search unit 121 may be included in the server device 102 .

So far, the configuration and operation of the information management system 100 according to Embodiment 1 of the present invention have been described.

Therefore, by referring to the productivity log, the work efficiency of the user can be managed.

(Modification 3)
In the first embodiment, an example has been described in which display of the managed information MO1 is stopped when an unregistered person of the managed information MO1 is included in the viewers. However, even when a non-registered person of the managed information MO1 is included in the viewers, the managed information MO1 may continue to be displayed.

In the case of this modification, the log generation unit generates a viewing log that further includes information (non-registered person viewing time information) regarding the time when the managed information MO1 was viewed by the unregistered person.

FIG. 19 shows an example of the browsing log 116f according to this modification. The browsing log 116f is the browsing log 116f obtained when the user V1 browsed the managed information MO1 from 10:00 on January 22, 2021, and then an unregistered person joined as a browsing person at 10:30 on the same day. For example. The process up to this point is the same as the browsing log 116a shown in FIG.

In the browsing log 116f, the information enclosed by the dotted line is added to the browsing log 116a. The added information corresponds to the fact that the non-registered person joined as a viewer until 10:50 on the same day and was viewed by only user V1 from 10:50 to 11:00 on the same day.

As can be seen by referring to FIG. 19, the viewing log 116f includes information about changes in viewers, which is different from that in the first embodiment. The information regarding the change of viewers according to this modification includes the viewer change date and time, the viewer information of the viewer after the change, whether or not each viewer is a registrant, and the history image ID.

The history image ID associated with the viewer change date and time is information for identifying history image data generated by the history image generator 112 from the viewer change date and time.

The browsing log 116f also includes non-registered person browsing time information. In the browsing log 116f shown in FIG. 19, the non-registered person browsing time information includes the date and time (start date and time and end date and time) and the length of time of browsing by the non-registered person.

The browsing time information for non-registered users may further include browsing information for non-registered users, and the browsing information may be associated with information regarding the browsing time of the browsing user identified by the browsing information. Since the non-registered person browsing time information can be created from the history included in the browsing log 116f other than the relevant information, it does not have to be included in the browsing log 116f according to this modification.

According to this modification, the viewing log includes information about the time when the managed information MO1 was viewed by the unregistered person. As a result, for example, when the possibility of leakage of information related to the managed information MO1 becomes a problem, by referring to the browsing log of the managed information MO1, it is possible to easily identify the point in time when the risk of leakage is high. be able to.

In addition, the output control unit 410 stops displaying the managed information MO1 on all the displays D and RD when the viewer included in the imaging data and the remote viewing information is unregistered. The output control unit 110 resumes the stopped display of the managed information MO1 on the display D when the cancellation instruction is accepted.

Here, the remote browsing information is information that can identify a viewer who browses the same managed information MO1 as the managed information MO1 displayed on the display D using the terminal device 440a. The remotely viewed information according to the present embodiment is imaging data generated by a camera RC that captures an image of the viewer of the managed information MO1 displayed on the display RD.

When stopping the display of the managed information MO1, only the displays D and RD viewed by the unregistered person may be stopped.

The history image generation unit 412 generates history image data in the same manner as the history image generation unit 112 according to the first embodiment.

The history image data according to the present embodiment includes management object information MO1 and imaging data that are displayed on the display D and captured by the camera C at the same time, and managed information that is displayed on the display RD at the same time. MO1 is included in association.

Specifically, for example, the history image generation unit 412 acquires image data including the management target information MO1 to be output to the display D and the terminal device 400a from the output control unit 410 in real time. Also, the history image generation unit 412 acquires the imaged data from the imaged data acquisition unit 111 in real time. The history image generator 112 associates the image data acquired at the same time with the imaging data. Then, the history image generation unit 112 generates history image data by further associating time information indicating the date and time when the image data and the captured data were acquired.

The management object information MO1 displayed by the display RD may be included in image data showing temporally consecutive images showing only the management object information MO1 displayed on the display RD. may be included in the image data that temporally continuously represents the .

The managed information MO1 displayed on the displays D and DR is substantially the same. Therefore, also in the present embodiment, as in the first embodiment, the history image data does not need to be associated with the management target information MO1 displayed on the display RD at the same time. As a result, it is possible to reduce the amount of history image data.

The management information storage unit 414 is a storage unit that stores information related to the management target information MO1, as in the first embodiment. In this embodiment, external management data 442 is stored in addition to the managed information MO1, registration data 122, and employee data 123 similar to those in the first embodiment.

In the external management data 442, as an example is shown in FIG. 22, an external ID, affiliation information, face information, and name are associated.

The external ID is information for identifying a viewer outside the company. The affiliation information, face information, and name of the external management data 442 are information indicating the organizational unit to which the viewer identified by the associated external ID (for example, company name), information for identifying the face, This is information indicating a name.

Both the employee data 123 and the external management data 442 are data for managing viewers, and may be combined as viewer management data, for example. Further, when face information of a registrant is used instead of an employee ID of the registrant as the registrant ID of the registration data 122, the employee data 123 and the external management data 442 are stored in the management information storage unit 414. It does not have to be.

A determination unit 415 acquires a viewer based on the imaging data and the remote viewing information. The determination unit 415 determines whether or not the acquired viewer is a registrant. This registrant is identified in the registration data 122 by the registrant ID associated with the managed information MO1 displayed on the display D when the imaging data is acquired.

The timing for determination by the determination unit 415 is, for example, when the display of the managed information MO1 on the displays D and RD is started, or when there is a change in the viewer included in the imaging data and the remote viewing information. .

As in the first embodiment, the log generation unit 417 generates a viewing log in which the viewer information is associated with the managed information MO1.

The viewer information according to the present embodiment is information for identifying the viewer included in the imaging data and the remote viewing information, and is the employee ID or outside company ID of the viewer. In the viewing log according to the present embodiment, the viewer information is associated with the managed information MO1 displayed on the display D when the imaging data and the remote viewing information including the viewer identified thereby are acquired.

Registration management unit 419 registers a registrant in registration data 122 in the same manner as registration management unit 119 according to the first embodiment. The registration management unit 419 includes a registration setting unit 419a and a registration updating unit 419b that replace the registration setting unit 119a and the registration updating unit 119b according to the first embodiment, respectively, as shown in FIG.

When receiving a setting instruction, the registration setting unit 419a registers the viewer included in the imaging data and the remote viewing information acquired when the setting instruction is received as a registrant of the managed information MO1. Register with 122.

When the cancellation instruction is accepted, the registration update unit 419b updates the unregistered person included in the imaging data and the remote viewing information when the display of the managed information MO1 related to the cancellation instruction is stopped, to the management object information. Register in the registration data 122 as a registrant for MO1.

Also, the registration setting unit 419 a and the registration updating unit 419 b register information about the viewer in the external management data 442 when the viewer registered in the registration data 122 is not registered in the external management data 442 .

The remote information acquisition unit 441 acquires remote viewing information specifying a viewer who views the same managed information MO1 as the managed information MO1 displayed on the display D using the terminal device 440 . The remote information acquisition unit 441 acquires imaging data generated by imaging with the camera RC from the terminal device 440 in real time.

The managed information MO1 is displayed on the display D and the display RD at approximately the same time. Therefore, the imaging data acquired at the same time as the transmission of the managed information MO1 from the output control unit 110 to the terminal device 440 (at the time of the transmission or immediately after) contains the managed information MO1 displayed on the display D and the The face of the viewer who views the same managed information MO1 using the terminal device 440 is included.

It should be noted that the terminal device 440 does not have to be equipped with an imaging means. In this case, the user ID of the terminal device 440 may be acquired as the remote viewing information, assuming that the viewer by the output means of the terminal device 440 is the user of the terminal device 440 . The user ID of the terminal device 440 is information for identifying the user. good too. If it is a login ID, it may be registered in the external management data 442 in association with the user's face information acquired by an appropriate method.

(Physical Configuration of Information Management Device 401)
The information management device 401 has generally the same physical configuration as the information management device 101 shown in FIG. 6, so detailed description thereof will be omitted for the sake of brevity. The physical configuration of the terminal device 440 is also the same as the physical configuration of the information management device 101 shown in FIG.

(Information management processing)
From here, the operation of the information management device 401 according to this embodiment will be described with reference to the drawings. Among the operations of the information management apparatus 401, search processing may be substantially the same as the search processing according to the first embodiment. Therefore, in the present embodiment, information management processing will be described with reference to the drawings.

23 and 24 are flowcharts showing an example of information management processing according to Embodiment 2 of the present invention. As in the first embodiment, the information management process is started, for example, when a start instruction is received by the instruction receiving unit 118 .

This embodiment will also be described using an example in which the start instruction includes the managed object ID "M1" corresponding to the managed object information MO1. An example in which the registration data 122b shown in FIG. 11 is stored in the management information storage unit 414 at the start of the information management processing will be described.

See FIG.
The determination unit 415 executes the process of step S101 as in the first embodiment.

For example, in step S101 according to the present embodiment, the registration data 122b has a registrant ID associated with the managed object ID "M1". Therefore, the determination unit 415 determines that the registrant is in the registration data 122a (step S101; Yes).

If it is determined that a registrant exists in the registration data 122 (step S101; Yes), the determining unit 415 determines whether or not all viewers included in the imaging data and the remote viewing information are registrants (step S302).

Step S302 is a process that replaces step S102 according to the first embodiment. The viewer related to step S302 is obtained not only based on the imaging data acquired when the setting instruction is accepted, but also based on the remote viewing information acquired when the setting instruction is accepted. The process of step S302 is sequentially performed substantially in real time based on the imaging data and the remote viewing information obtained in real time by the imaging data obtaining unit 111 and the remote information obtaining unit 441, respectively.

For example, as shown in FIG. 20, the viewers at the start of the information management process are viewers V1 and V2 using the information management device 401 and viewer V10 using the terminal device 400a. In the registration data 122b, the registrant IDs associated with the managed ID "M1" include "V1" and "V2" corresponding to the viewers V1 and V2, but there is no registrant ID corresponding to the viewer V10. In this case, the determination unit 415 determines in step S302 that none of the viewers are registrants (that is, the viewers V1, V2, and V10 include the unregistered person V10).

If "No" is determined in step S101 and if "No" is determined in step S302, the instruction receiving unit 118 executes the process of step S111 as in the first embodiment. If "No" is determined in step S111, instruction receiving unit 118 terminates the information management process, as in the first embodiment.

If "Yes" is determined in step S111, the registration setting unit 119a registers the viewer in the registration data 122b as a registrant of the managed information MO1 related to the start instruction (step S312).

Step S312 is a process that replaces step S112 according to the first embodiment. In step S312, not only the imaging data acquired when the setting instruction is accepted, but also the viewer included in the remote viewing information acquired when the setting instruction is accepted is registered in the registration data 122b.

For example, as described above, in the registration data 122b, the registrant ID corresponding to the viewer V10 is not associated with the managed ID "M1". is determined to have been accepted.

In this case, in step S312, the registration setting unit 119a registers the viewer V10 in the registration data 122b. At this time, if the viewer V10 belongs to an organization other than the company A and is not registered in the external management data 442, the registration data 122b registers the viewer V10 in the external management data 442 as well. As a result, the registration data 122c shown in FIG. 26 and the external management data 442 shown in FIG.

When it is determined "Yes" in step S302 and after the process of step S312 is executed, the processes of steps S103 and S104 similar to those of the first embodiment are executed.

Here, as described above, in the registration data 122b, the registrant ID corresponding to the viewer V10 is not associated with the management target ID "M1". is registered. FIG. 27 shows an example of the browsing log 416a created in this case.

The browsing log 416a, like the browsing log according to the first embodiment (for example, the browsing log 116a shown in FIG. 9), is for identifying the managed object ID "M1" of the managed information MO1 related to the start instruction and the user. user ID "V1". In addition, the viewing log 416a includes information regarding each of the start instruction and the viewing start, similar to the viewing log according to the first embodiment.

View log 416a also includes information about registrations. In the registration information, the registration date and time are associated with the registrant ID. The browsing log 416a shown in FIG. 27 shows an example in which the date and time when the registrant V10 was registered in the external management data 442 and the registrant ID of the registrant V10 are associated with each other.

The process of step S105 similar to that of the first embodiment is performed. If "No" is determined in step S105, the determining unit 415 determines whether or not there is a change in the viewers included in the imaging data and the remote viewing information (step S306).

Step S306 is a process that replaces step S106 according to the first embodiment. In step S306, not only the viewers included in the imaging data but also the viewers included in the remote viewing information are referenced to determine whether or not the viewers have changed.

If it is determined that there is no change in the viewer (step S306; No), the process of step S105 is performed again.

Assume that the viewer has changed from the state shown in FIG. 20 to the state shown in FIG. In FIG. 28, viewer V3 who views managed information MO1 using terminal device 440b joins viewers V1, V2, and V10 shown in FIG. In such a case, since the viewer V3 is added to the viewers included in the imaging data and the remote viewing information, the determination unit 415 determines that there is a change in the viewers V1, V2, and V10.

A terminal device 440 b used by viewer V<b>3 is an example of the terminal device 440 . That is, the terminal device 440b is configured in the same manner as the terminal device 440a, and is connected to the information management device 101 via the network N so as to be able to communicate with each other.

Again, refer to FIG.
If it is determined that there is a change in the viewers (step S306; Yes), the determination unit 115 determines that all the viewers after the change are registrants (that is, the viewers after the change include non-registered users). It is determined whether or not (step S307).

Step S307 is a process that replaces step S107 according to the first embodiment. The determination process in step S307 is preferably performed in substantially the same manner as the determination process in step S302.

Here, as described above, the viewers of the managed information MO1 change from the state shown in FIG. 20 (viewers V1, V2, V10) to the state shown in FIG. 28 (viewers V1, V2, V3, V10). Suppose 26 is stored in the management information storage unit 414 at this time.

In this case, in the registration data 122c, the registrant IDs "V1", "V2", "V3" and "V10" of all viewers V1, V2, V3 and V10 are associated with the managed ID "M1". . Therefore, in step S307, the determining unit 115 determines that all of the viewers after the change are registrants (that is, the viewers V1, V2, V3, and V10 do not include non-registrants).

When it is determined that all the viewers after the change are registrants (step S307; Yes), as shown in FIG. 23, the processes of steps S103 and S104 are performed again.

FIG. 29 shows an example of the browsing log 416b created here.

In the browsing log 416b shown in FIG. 29, the information enclosed by the dotted line is added. The added information is described here.

Viewing log 416b includes information about changes in viewers as the display continues. The information about the registration included in the viewing log 416b is for the case where all of the viewers V1, V2, V3, and V10 after the change are registrants. It is different from the information about the registration that is included.

The information regarding changes in viewers included in the viewing log 416b differs from the information regarding changes in viewing users included in the viewing log 116b shown in FIG. 12 in that it further includes history image IDs. The history image ID associated with the viewer change date and time is information for identifying the history image data generated by the history image generation unit 412 from the viewer change date and time.

If "Yes" is determined in step S105, the log generation unit 117 generates a browsing log (step S113) as in the first embodiment, and ends the information management process. FIG. 30 shows an example of the browsing log 416c generated in step S113.

In the browsing log 416c shown in FIG. 30, the viewing end date and time are added to the browsing log 416b shown in FIG. 29, as indicated by the dotted line.

If "No" is determined in step S307, the output control unit 410 stops outputting the managed information MO1 related to the start instruction to the display D and the display RD. As a result, the output control unit 410 stops displaying the managed information MO1 on the display D and the display RD (step S308).

Step S109 similar to that of the first embodiment is performed. If "No" is determined in step S109, as shown in FIG. 23, the log generation unit 117 executes the process of step S113 similar to that of the first embodiment, and ends the information management process.

If it is determined "Yes" in step S109, the registration updating unit 119b registers the viewer determined as the unregistered person in step S307 in the registration data 122 as a registrant (step S310).

Step S310 is a process that replaces step S110 according to the first embodiment. In step S310, not only the imaging data acquired when the setting instruction is accepted, but also the viewer included in the remote viewing information acquired when the setting instruction is accepted is included in the registration data 122 if the viewer is an unregistered person. be registered.

After the process of step S310 is performed, as shown in FIG. 23, the processes after step S103 are performed again.

So far, the information management processing according to the present embodiment has been described.

According to the information management processing according to the present embodiment, it is possible to generate a viewing log for each managed information viewed using not only the information management device 401 but also the terminal device 440 . For example, when the possibility of leakage of information related to the managed information MO1 becomes a problem, by referring to the browsing log of the managed information MO1, it is possible to prevent leakage, including the case where the information is browsed via the network N. High risk points can be easily identified. In addition, it is possible to easily check the details by looking at the history image data corresponding to that point in time. Therefore, information can be managed more appropriately.

So far, the configuration and operation of the information management system 100 according to Embodiment 1 of the present invention have been described.

According to the present embodiment, the viewer information for identifying the viewer included in the imaging data and the remote viewing information is associated with the management target information MO1 that is output to the display D when the imaging data is captured. A log is generated. As a result, a browsing log can be generated for each managed information browsed not only by the information management apparatus 401 but also via the network N. FIG. Therefore, as described above, information can be managed more appropriately.

According to the present embodiment, based on the registration data 122, it is further determined whether or not the viewer specified by the remote viewing information is the registrant. Further, in the browsing log, for example, by associating the determination result of each viewer, the determination result is associated with the managed information MO1.

As a result, for example, by searching the browsing log, it is possible to easily search for the managed information MO1 that may have been browsed by an unregistered person via the network N. Therefore, information can be managed more appropriately.

According to the present embodiment, when an unregistered person is included in the viewers, the output of the managed information MO1 on the display D and the output of the managed information MO1 to the terminal device 440 are all stopped. This can reduce the possibility of an unregistered person browsing the managed information MO1. Therefore, information can be managed more appropriately.

When an unregistered person is included in the viewers, out of the output of the managed information MO1 on the display D and the output of the managed information MO1 to the terminal device 440, the output used for browsing by the unregistered person is may be stopped.

Here, the output used for browsing by the unregistered person is the display on the display D when the unregistered person is using the display D to browse the managed information MO1. Also, when the unregistered person is viewing the managed information MO1 using the display RD, the display is on the display RD.

This also makes it possible to reduce the possibility of unregistered persons viewing the managed information MO1. Therefore, information can be managed more appropriately.
