<First embodiment>
(System configuration)
FIG. 1 is a diagram illustrating an example of an information analysis system. The information analysis system includes a plurality of terminal devices 11a and 11b, a log management server 12, and an information analysis device 13. The terminal devices 11a and 11b are examples of terminals arranged in a company. The log management server 12 manages an operation log (operation history) of an application program executed on a terminal device arranged in the company and a position history described later. The information analysis device 13 is an example of an information analysis device that analyzes an operation history of an application program in a terminal device arranged in a company. These devices are connected via various networks 50 such as an intranet including a LAN (Local Area Network) and the Internet. When the matters common to the terminal devices 11a and 11b are described, they are simply referred to as the terminal device 11.

  The log management server 12 may be arranged in a company where the terminal device 11 is installed, or may be arranged in another company. Similarly, the information analysis apparatus 13 may be arranged in a company where the terminal device 11 is installed, or may be arranged in another company. Further, the log management server 12 and the information analysis device 13 may be managed by the same company, or may be managed by another company.

  The terminal device 11 includes a monitoring unit 14 and a receiver 16. The monitoring unit 14 monitors the name of the application program running on the terminal device, the user's man-hours for the input device of the terminal device when the application program is running, and records it as an operation history. The operation history may include, for example, the following information.

-Terminal device identification information: Computer name, IP address, MAC address, etc.-User name-ID of the user logged in to the terminal device-Operation date / time ... Date / time when operation history was acquired-Active Window application name ... process name, etc.-Active window title name ... caption name (name of file being edited, etc.)
・ Number of keystrokes on keyboard ・ Input character code: Full-width / half-width, 2-byte character / single-byte character, Unicode / EUC / ISO / JIS, etc. ・ Input confirmation character: Confirmed through front end processor (FEP) Characters ・ Moving distance of pointing device pointer ・ Number of clicks on pointing device The monitoring unit 14 of the terminal device 11 creates an operation history for each preset monitoring period (e.g., 1 minute) and stores it in the log management server 12. Send.

  The receiver 16 is connected to the USB port of the terminal device 11, and receives a signal including identification information from the transmitter 17 (for example, an active tag or a passive tag) every predetermined period (eg, 2 minutes), Obtain the radio field intensity of the received signal. The identification information is a unique identification number of the transmitter 17 assigned so as not to overlap in the information analysis system. The transmitter 17 is used as an ID card carried by a user (operator) such as an employee, for example.

  Then, the monitoring unit 14 creates a position history every predetermined period (eg, 2 minutes) based on information (unique identification number and radio wave intensity) output from the receiver 16 and transmits the position history to the log management server 12.

  The reception performance of the receiver 16 has a reception performance capable of determining whether or not the transmitter 17 exists within a radius of about 1 m from the receiver 16. Note that the operator position detection method described here is merely an example, and a radio ranging technique, a radio positioning technique, or the like may be used as long as the rough position of the operator can be detected.

  Various conditions for the terminal device 11 to transmit the operation history and the position history acquired in this way to the log management server 12 can be considered. For example, when a predetermined time elapses (for example, every 2 hours), when an operation history and a position history exceeding a predetermined amount are accumulated in the terminal device 11, when the terminal device 11 is activated, the terminal device 11 instructs to shut down. The log management server 12 is requested to transmit the operation history and the position history.

  The log management server 12 is an information processing apparatus (computer) that accumulates operation histories and position histories collected from each of the plurality of terminal apparatuses 11 and transmits the accumulated operation histories and position histories to the information analysis apparatus 13. As shown in FIG. 1, the log management server 12 includes a log management DB 15. DB is an abbreviation for database. The log management server 12 records an operation history for each terminal device (or for each user) in the log management DB 15 based on the operation history and the position history received from the terminal device 11.

  The information analysis device 13 is an information processing device including an analysis unit 18 and an analysis result DB 19. The information analysis device 13 creates and outputs a business analysis based on the operation history and the position history received from the log management server 12 via the network 50.

  For example, the analysis unit 18 creates an analysis result for each user or each terminal device, and records the created analysis result in the analysis result DB 19. The analysis unit 18 outputs the analysis result recorded in the analysis result DB 19 to the display device as a graph or a table, outputs it to a recording medium by a printing device, outputs it as the text of an e-mail, or as a Web page of a Web site Or output.

  The transfer of the operation history from the log management server 12 to the information analysis apparatus 13 is executed via the network 50. Therefore, the network interface of the information analysis device 13 is an example of an input unit that inputs an operation history and a position history in the terminal device 11. Further, the operation history may be transferred from the log management server 12 to the information analysis apparatus 13 using an external storage medium (FD, MO, USB memory, CD-R, DVD-RAM, etc.). The information analysis device 13 includes such a drive device for an external storage medium, and functions as an input means for inputting an operation history in the terminal.

  As shown in FIG. 10, the information analysis system may include a network camera 60 that captures an operator as image information. The network camera 60 may be a camera connected to a network and assigned an IP address, or may be a Web camera provided in the terminal device 11. The network camera 60 is installed toward the user's seat so that an image or a moving image of the user who is operating the terminal device 11 to be monitored can be acquired. The monitoring unit 14 may control the network camera 60 in response to a request from the information analysis device 13 to acquire an image and transmit the image to the information analysis device 13, or acquire an image at a constant period and log management server 12 to send. This image may be transmitted as a position history together with the identification information described above, or may be transmitted as an operation history.

(Log management database)
The CPU 21 of the terminal device 11 transmits the operation history and the position history to the log management server 12 via the network interface 24 according to the monitoring program 28. The CPU 31 of the log management server 12 receives the operation history and the position history via the network interface 34 and records them in the log management DB 15 in the HDD 45.

(Information analysis processing)
FIG. 5 is a flowchart showing the flow of information analysis processing. The CPU 41 of the information analysis device 13 executes this information analysis processing according to the information analysis program 47. The CPU 41 functions as the analysis unit 18 by executing each process shown in this flowchart.

  The CPU 41 inputs an operation history to the memory 43 (S501). For example, the CPU 41 may receive an operation history from the log management DB 15 of the log management server 12 or may read the operation history from a data storage medium such as a CD-ROM. Therefore, the network interface 44 and the CD-ROM drive device used for reception function as input means. Note that the unit for reading the operation history can be freely set such as a user name, a PC name, and an operation start date and time. As described above, the CPU 41 and the analysis unit 18 function as an acquisition unit that acquires an operation history indicating an operation content of the operator with respect to the terminal device 11.

  The CPU 41 determines whether or not a record exists in the operation history of the memory 43 (S502). The record also includes non-operation information (for example, the number of keystrokes is 0, and the pointer movement distance is 0 pixels).

  If the record does not exist (NO in S502), the CPU 41 ends the task analysis process. On the other hand, when the record exists (YES in S502), the CPU 41 reads the record from the memory 43 (S503). The CPU 41 executes an operation status analysis process for the read record (S504). In this analysis process, for example, it is determined as “operating” when either the number of keyboard strokes or the pointer movement distance is equal to or greater than a predetermined value, and “unoperated” when it is equal to or less than the predetermined value. As described above, the CPU 41 and the analysis unit 18 function as a determination unit that determines an operation situation from the acquired operation history.

  Then, the CPU 41 records the analysis result of the operation status in the analysis result DB 19 (S505).

  Next, the CPU 41 inputs the position history to the memory 43 (S506). As described above, the position history includes the unique identification number obtained from the signal transmitted by the transmitter 17 carried by the operator, and information indicating the signal strength of the signal. Note that the position history input method is the same as the operation history input method. Thus, the CPU 41 and the analysis unit 18 function as an acquisition unit that acquires a position history indicating position information about the operator.

  The CPU 41 extracts corresponding operation history information based on the PC name, associates the position history information with the operation history information, and records it in the analysis result DB 19 (S507).

  FIG. 6 shows an example of a user management table stored in the HDD 45. The CPU 41 reads the unique identification number of the position history information shown in FIG. 4, and acquires the PC name corresponding to the unique identification number from the user management table shown in FIG. Thereby, the CPU 41 identifies the operation history information corresponding to the unique identification number, and records the position history information in the analysis result DB 19 in association with the operation history information.

  The CPU 41 refers to the state management table shown in FIG. 7 and determines the presence status (present / separated) (S508). According to FIG. 7, the CPU 41 determines that the operator corresponding to the unique identification number is “present” if the radio wave intensity S exceeds the first threshold value xdBm, and the radio wave intensity S is the first radio wave intensity S. If the threshold value xdBm is not exceeded, it is determined that the operator is “seated”. Note that the CPU 41 may change the predetermined value x for each person to be monitored. This is because the radio wave environment is expected to be different for each person to be monitored, and it is considered that the determination accuracy of the presence status is lowered when the same threshold is used for a plurality of persons to be monitored. In this case, it is assumed that the threshold value x for each person to be monitored is stored in the HDD 45 in association with the user name or the PC name.

  FIG. 8 shows another example of the state management table. In this example, two threshold values x and y (x> y) are used to classify presence information in more detail. According to this example, the CPU 41 determines that the user is present when the radio field intensity S exceeds the predetermined value xdBm, and the CPU 41 determines that the monitoring is performed when the radio field intensity S is less than the predetermined value xdBm and exceeds the predetermined value y. It is determined that the subject is near his / her seat, and when the radio wave intensity S is equal to or less than a predetermined value ydBm, the user is determined to be “seated”. x and y may also be threshold values determined according to the radio wave environment at the subject person's own seat.

  As described above, the CPU 41 and the analysis unit 18 function as a determination unit that determines the presence status from the acquired position history. Furthermore, the CPU 41 and the analysis unit 18 may determine that the operator does not exceed the first threshold value x and the signal strength exceeds the second threshold value y that is smaller than the first threshold value x. May be determined to exist near the user's seat.

  FIG. 9 is a diagram illustrating an example of an analysis result regarding absence from a seat. Here, only necessary data is illustrated, and other data is omitted. In the presence determination column 801, the result of the presence determination executed in S508 is stored. The operation status column 802 stores the analysis result of the operation status acquired in S504. The business analysis result column 803 stores the business analysis result obtained by the CPU 41 from the presence determination result and the analysis result of the operation status. If the CPU 41 is present and operating, the CPU 41 determines that the PC is being operated. In addition, the CPU 41 determines that work other than the PC operation is being performed if the monitoring target person is present near his / her seat and is not operated. Further, the CPU 41 determines that the user is away from the seat if he / she is away from the seat and is not operated. Further, the CPU 41 determines that there is a possibility of impersonation by another person if it is away from the seat and being operated.

  Thus, even if the PC operation status is “not operated”, if the presence status is “present”, it can be analyzed that the work other than the PC operation is being performed, and the presence status is “seated”. In the case of, it can be analyzed that the meeting or going out. As described above, the CPU 41 and the analysis unit 18 function as an analysis unit that analyzes the business situation of the operator from the operation situation and the presence situation.

  The CPU 41 stores the business analysis result (FIG. 9) in the analysis result DB 19 and outputs it to the output unit 46 (S509).

  As described above, more detailed task analysis can be performed by performing task analysis using the operation history and the position history. For example, it can be determined whether the PC is being operated or is away. If a plurality of threshold values for determining the position are prepared, further detailed analysis results can be provided. For example, if the operator's operation status indicates that the terminal device is not operated, and if the presence status indicates that the user is present, the operator uses the terminal device although the operator is present The CPU 41 may analyze what is not performed. As a result, it is understood that the person to be monitored is performing another action such as sleeping or reading. Also, if the operator's operation status indicates that the terminal device is being operated, and if the presence status indicates that the user is away from the desk, another person different from the operator may use the operator's terminal device. If used, the CPU 41 may analyze. There is a security problem when another person is working as a principal. Therefore, measures for improving security, such as protecting the terminal device 11 with a password, can be taken.

  It is also assumed that the transmitter 17 to be carried by a legitimate operator is illegally acquired by another user and the terminal device 11 is operated. As a countermeasure against such impersonation, the image information of the operator photographed by the network camera 60 may be used as the position information of the position history. By checking the image information of the operator photographed by the network camera 60 with the image information of the authorized monitoring subject recorded in advance in the log management DB 15, it is possible to take measures against impersonation. In other words, the CPU 41 of the information analysis device 13 determines that the image is not satisfied if the operator's image matches the image of the monitoring target person, and determines that the image is not satisfied if the both do not match.

  Specifically, first, the network camera 60 is installed for each terminal device 11. It is assumed that the unique identification information of the operator who should operate the terminal device 11 is recorded in advance for each terminal device 11. The transmitter 17 transmits this unique identification information. The receiver 16 receives the unique identification information from the transmitter 17. The network camera 60 acquires image information of an operator who is operating the terminal device 11. The terminal device 11 transmits image information together with the unique identification information acquired by the receiver 16. The terminal device 11 may transmit only the unique identification information acquired by the receiver 16, and the network camera 60 may transmit image information in parallel therewith. The log management server 12 receives the unique identification information and the image information, and configures and stores a position history as position information. The CPU 41 of the information analysis device 13 extracts unique identification information and image information from the position history read from the log management server 12. Further, the CPU 41 reads out the image information of the authorized monitoring subject stored in advance in the HDD 45 in association with the unique identification information, and compares the received image information with the previously recorded image information. The CPU 41 functions as a determination unit that determines that it has not been completed if they match, and determines that it has not been completed if they do not match. Note that the CPU 41 of the information analysis device 13 may directly receive the information from the terminal device 11 by requesting the terminal device 11 for unique identification information and image information. In addition, the information analysis apparatus 13 may directly communicate with the network camera 60 to acquire image information and the IP address of the network camera 60. The IP address of the network camera 60 and the unique identification information of the monitoring subject are registered in advance in association with the table, and the CPU 41 acquires the IP address from the unique identification number or acquires the unique identification information from the IP address. Or The CPU 41 acquires an IP address from the unique identification information of the monitoring subject and accesses the network camera 60 that captures the monitoring subject to acquire an image.

  Thus, the position history may include image information obtained by photographing the operator as the position information.

  Here, the network camera 60 is a camera system having a network communication function, and may be a camera having a communication function, a computer connected to a web camera, or a smartphone having a camera function. Also good.

  Note that the CPU 41 may execute identity verification using the image information described above when it is determined that the presence status indicates presence. The processing for comparing image information is more computationally intensive than the processing for comparing text data. Therefore, the personal identification process using the image information may be executed with the minimum necessary amount.

Incidentally, the receiver 16 may receive signals (radio waves) from a plurality of transmitters 17. For example, if the unique identification information of the terminal device 11b (user B) is recorded in the position history of the terminal device 11a (user A), the terminal device even if the PC operation status of the terminal device 11a is “not operated” An analysis that user A and user B are having a meeting using 11a may be possible.
<Second embodiment>
The position information about the operator may be acquired from the image information. For example, the network camera 60 may photograph the operator with the photographing function, acquire position information using the positioning function, and embed the position information in the image information as EXIF information. Thereby, the CPU 41 of the information analysis device 13 can acquire the position information of the operator from the image information. The positioning function includes a global positioning system (GPS) reception module. The position where the terminal device 11 is installed can be specified by this position information.

  The network camera 60 may execute shooting at predetermined intervals (eg, every 1 minute), or may execute shooting according to an instruction from the administrator / operator. The acquired position information is stored as a position history.

  The CPU 41 performs business analysis using the position history including the position information and the operation history. For example, the CPU 41 can determine whether or not the operator who is instructed to work from home is actually working (at home) at home. In other words, this is an effective technique for obtaining an operation history of telecommuting.

  The position information described above may be position information determined from, for example, infrared rays transmitted from the terminal device 11, a magnetic sensor, or an ultrasonic sensor, in addition to the position information obtained by the network camera 60.

<Other embodiments>
The log management server 12 and the information analysis device 13 described above may be realized on the same server, or may be executed on different servers. In the former case, there is an advantage that the log management server 12 and the information analysis device 13 do not need to perform data communication through the network 50. In addition, the information analysis device 13 includes a log management DB 15, an analysis unit 18, and an analysis result DB 19. As described above, by realizing the log management server 12 and the information analysis device 13 on the same server, it is possible to manage the operation history and analysis results in the same company. Therefore, analysis considering security can be performed.

  Here, as an example, the present invention has been described using an example in which the present invention is applied to a company. However, the present invention may be adopted in public institutions such as government offices and educational institutions such as schools. Furthermore, a telecommuter in a company or public institution may be employed as a monitoring target. This is because the present invention can be applied by associating the PC name and the user name with the terminal device 11 to be monitored and the person to be monitored in any case.

  The terminal device 11 and the log management server 12 may function as an information recording device.
