Description

Technical Field

[0001] The present disclosure relates to a terminal device, an information processing system, a method, and a computer program.

Background Art

[0002] The spread of the novel coronavirus disease has led to the rapid spread of remote work. For example, company employees who perform remote work participate in online meetings from a terminal at home or access the company's computer through a remote desktop. Under such circumstances, companies or other organizations have a need to grasp the activities of members who perform remote work, for example, the status of participation in online meetings.

[0003] Some vendors that provide applications for online meetings disclose an application programming interface (API) for reference to information related to online meetings or extension of functions. By utilizing such an API, it is possible to acquire and record information such as when an online meeting is held and who participated in the meeting.

[0004] Patent Document 1 proposes a technique for recording the activities of participants and creating a transcript that can be reproduced in chronological order in a client-server type online meeting system. This online meeting system can automatically record the times of entry and exit of each participant to an online meeting.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The online conferencing system proposed in Patent Document 1 has the disadvantage of requiring a dedicated server machine, resulting in high system construction costs and low versatility. Furthermore, if other types of applications are used for online conferencing, the functions of the system in Patent Document 1 will not work.

[0007] The choice of application for online meetings is at the discretion of the user (e.g., meeting organizer or participant), and it is common for a single user to use multiple types of online meeting applications. Adding functionality to record each user's activity using publicly available APIs for all possible applications that may be used is not practical from a cost and effort standpoint. In addition, some applications do not have publicly available APIs. While it is conceivable to directly monitor the content of transmitted data to understand user activity, this method is also disadvantageous in terms of versatility and cost, given the diversity of data formats and communication methods.

[0008] In light of these circumstances, this disclosure aims to provide a general-purpose, application-independent mechanism for understanding user activity in remote work environments. [Means for solving the problem]

[0009] From one perspective, a terminal device is provided comprising: a communication unit that communicates over a network; and a monitoring unit that monitors the use of a port for communication between the communication unit and an external device, and records historical information regarding user activity associated with the communication on a recording medium based on the open time when the port is opened and the close time when the port is closed, wherein the monitoring unit determines the open time or the close time of the port based on the state of the port associated with the packet when the destination of the packet communicated by the communication unit is included in a predefined destination list. Corresponding information processing systems, methods, and computer programs are also provided. [Effects of the Invention]

[0010] The technology disclosed herein allows for the monitoring of user activity during remote work using a general-purpose mechanism that is not dependent on a specific application. [Brief explanation of the drawing]

[0012] The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features from the multiple features described in the embodiments may be combined arbitrarily. Furthermore, identical or similar configurations will be given the same reference numeral, and redundant descriptions will be omitted.

[0013] <1. First Embodiment> <1-1. System Configuration> First, an overview of the information processing system configuration will be described. Figure 1 is a schematic diagram showing an example of the configuration of information processing system 1 according to the first embodiment. Referring to Figure 1, information processing system 1 includes a plurality of application servers 20a, 20b, 20c and a plurality of client terminals 100a, 100b, 100c. Network 10 interconnects the application servers 20a, 20b, 20c and the client terminals 100a, 100b, 100c. Network 10 may be any combination of a public network (e.g., the Internet) and a private network (e.g., a home network). Network 10 may consist of a plurality of network segments, and each network segment may be a wired network or a wireless network.

[0014] Application server 20a is a server device that provides a first type of online meeting service. For example, with the support of application server 20a, client terminal 100a can host its own online meeting or remotely access an online meeting hosted by another client terminal. Application server 20b is a server device that provides a second type of online meeting service, which is different from the first type. The first and second types of online meeting services may be services provided by different vendors, for example. Application server 20c is a server device that provides online services other than online meetings (for example, online games).

[0015] Client terminals 100a, 100b, and 100c are terminal devices used by different users. Each of client terminals 100a, 100b, and 100c may be any type of information processing device, such as, for example, a personal computer (PC), a smartphone, or a mobile phone.

[0016] In the following description, when there is no need to distinguish between client terminals 100a, 100b, and 100c from each other, they are collectively referred to as client terminal 100 by deleting the alphabet at the end of the reference numeral. Similarly, application servers 20a, 20b, and 20c are collectively referred to as application server 20.

[0017] FIG. 1 shows an example in which information processing system 1 includes three application servers 20, but information processing system 1 may include any number of application servers 20. Similarly, FIG. 1 shows an example in which information processing system 1 includes three client terminals 100, but information processing system 1 may include any number of client terminals 100. One client terminal 100 may be shared by a plurality of users. In that case, by a user logging in to client terminal 100 (for example, using a user ID and password, or other authentication information), it becomes possible to identify which user is using client terminal 100.

[0018] <1-2. Configuration of Client Terminal> As shown in FIG. 1 in relation to client terminal 100a, client terminal 100 includes a network interface (I / F) 101, a memory 102, an input / output (I / O) device 103, a storage device 104, and a processor 110. <​The network I / F 101 is a communication unit for the client terminal 100 to communicate with other devices via the network 10. The network I / F 101 may include one or both of a wireless communication I / F and a wired communication I / F. In the present embodiment, in the network layer, the network I / F 101 identifies a host involved in communication by an IP (Internet Protocol) address, and in the transport layer, it identifies an application involved in communication by a port number. The IP address of the network I / F 101 is set fixedly in advance or set dynamically when the client terminal 100 is connected to the network 10. The port number used by the network I / F 101 for communication is specified for each application operating in the processor 110 described later.

[0020] The memory 102 may be any combination of a volatile memory (e.g., RAM (Random Access Memory)) and a non-volatile memory (e.g., ROM (Read-Only Memory)). The RAM provides a temporary storage area for operations by the processor 110. The ROM stores in advance computer programs (e.g., a boot program, BIOS, OS, and a plurality of application programs) to be executed by the processor 110. Some of these computer programs may be stored in the storage device 104 described later.

[0021] The I / O device 103 includes an input device for inputting information to the client terminal 100 and an output device for outputting information from the client terminal 100. The input device includes, for example, one or more of a touch sensor, a keyboard, a pointing device, a button, a switch, and a microphone. The output device includes, for example, one or more of a display, a speaker, a light, and a vibrator. Note that the I / O device 103 may include a voice processing module for recognizing input voice and synthesizing output voice. The I / O device 103 functions as a user interface for the client terminal 100 to interact with the user.

[0022] The storage device 104 is a storage device capable of storing large amounts of data. The storage device 104 may include, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive). In this embodiment, the storage device 104 stores, for example, a destination list, port monitoring results, and user activity history information (hereinafter referred to as activity history information), which will be described later.

[0023] The processor 110 implements all the functions of the client terminal 100 by executing computer programs stored in the memory 102. The processor 110 may include any processing circuit, such as a central processing unit (CPU), a microprocessor, or a microcontroller. The client terminal 100 may have a variety of functions that a typical user terminal has. However, for the sake of simplicity, only functions related to user activities involving communication with external devices will be described here. Referring to Figure 1, the functions implemented by the processor 110 include multiple applications 120a, 120b, ..., and a monitoring unit 130.

[0024] Application 120a is a first type of online meeting application. For example, application 120a is launched as a result of a user calling application 120a from the operating system's application menu via I / O device 103. When the user specifies a pre-issued URL (Uniform Resource Locator) for a specific online meeting, application 120a opens the port associated with application 120a and accesses the corresponding application server 20a. This allows the user to participate in the online meeting (after undergoing authentication procedures if necessary). While the port associated with application 120a is open on client terminal 100, an external device (e.g., application server 20a or another client terminal) can deliver video, audio, and other data of the online meeting to application 120a on client terminal 100. Communication between application 120a and the external device may be conducted using any TCP / IP-based communication protocol, such as HTTP (Hypertext Transfer Protocol) or WebSockets. When the user leaves the online meeting, application 120a closes the port that was open.

[0025] Application 120b is a second type of online meeting application, distinct from the first type. That is, on the client terminal 100, two or more types of online meeting applications can operate by having the processor 110 execute the corresponding application program stored in memory 102. Similar to application 120a, when a user joins an online meeting, application 120b opens the port associated with application 120b and accesses the corresponding application server 20b. Also, when a user leaves the online meeting, application 120b closes the port associated with application 120b.

[0026] Applications 120a and 120b may each run as a web application in a web browser, or they may provide their own application screens. The program code for running as a web application may be dynamically downloaded from the corresponding application server 20 instead of being pre-stored in memory 102.

[0027] The client terminal 100 may have further applications that involve communication with external devices. For example, the client terminal 100 may have a game application that communicates with the application server 20c using a specific port and enables the user to participate in an online game. The port for communicating with the application server 20c is also opened when the user joins the online game and closed when the user leaves the online game.

[0028] The monitoring unit 130 is a functional module introduced to manage user activity performed on the client terminal 100. The monitoring unit 130 is implemented as a software module, for example, by the processor 110 executing a corresponding computer program (e.g., a client program) stored in memory 102.

[0029] The monitoring unit 130 monitors the use of ports for communication between the client terminal 100 and external devices, and records the open time when each port is opened and the close time when each port is closed. The ports here are typically TCP (Transmission Control Protocol) ports or UDP (User Datagram Protocol) ports.

[0030] In this embodiment, the communications monitored by the monitoring unit 130 may be remote access to destinations included in a predefined destination list. Figure 2 shows an example of the configuration of a destination list 121 that defines destinations to be monitored. The destination list 121 includes at least one destination entry, each consisting of a "destination URL" and a "service name". The "destination URL" represents the URL of the application server 20 to be accessed, which may be written in the header of the request packet for remote access. The "service name" represents the name of the online service identified by the "destination URL". The first destination entry in the destination list 121 in Figure 2 indicates that access to an online meeting service named "Online MTG" is made with the URL "https: / / onlinemeeting.com" as the destination. The second destination entry indicates that access to an online meeting service named "Web MTG" is made with the URL "https: / / webmeeting.net" as the destination. Thus, in this embodiment, the destination list 121 can define destinations associated with two or more online conferencing applications (and destinations for other online services). In the actual request packet, the destination URL may include additional parts such as a path name, query string, and destination port number after the hostname.

[0031] The recipient list 121 may be stored in any format, such as a configuration file or a database table, by the storage device 104. The monitoring unit 130 may add, edit, or delete entries in the recipient list 121 according to settings received via the network interface 101 (for example, from other users with administrator privileges).

[0032] The monitoring unit 130 determines the open time of the port associated with a packet communicated via the network interface 101, based on the port's state, if the destination of the packet is included in the destination list 121. Similarly, the monitoring unit 130 determines the close time of a port based on the state of the monitored port. For example, if a packet specifying a destination URL included in the destination list 121 is detected, and the port associated with that packet changes from a closed state to an open state, the monitoring unit 130 records the port's open time as a monitoring result. Also, if a packet specifying the same destination URL is detected, and the port associated with that packet changes from an open state to a closed state, the monitoring unit 130 records the port's close time as a monitoring result. For example, when a user joins and leaves an online meeting, the online meeting application sends notifications of these actions to the application server. By capturing these notification packets and determining the corresponding port state changes, the timing of the start and end of user activity, such as a user attending an online meeting, can be determined.

[0033] Figure 3 shows an example of port monitoring results by the monitoring unit 130. The port monitoring results 123 shown in Figure 3 include four entries, each indicating a change in the state of a port on the client terminal 100. The first entry indicates that at 10:00 on April 1, 2022, a port identified by port number "1234" was opened for activity by a user named "UserA". This port is for an online service identified by the destination URL "https: / / onlinemeeting.com". The second entry indicates that at 10:30 on April 1, 2022, a port identified by port number "3456" was closed. The third entry indicates that at 11:10 on April 1, 2022, a port identified by port number "3456" was opened for activity by a user named "UserA". This port is for an online service identified by the destination URL "https: / / webmeeting.net". The fourth entry indicates that the port identified as port number "3456" was closed at 11:50 AM on April 1, 2022.

[0034] When each monitored port is closed, the monitoring unit 130 determines that user activity involving communication has ended and generates activity history information based on the open and close times of the port. For example, the activity history information may include a combination of the start and end times of the user activity, where the start time corresponds to the open time of the relevant port and the end time corresponds to the close time of the relevant port. By recording the start and end times of such user activities, it becomes possible to objectively grasp the specific progress of remote work, such as when each user performed communication-related activities and for how long. Additionally or alternatively, the activity history information may include the duration of the user activity, for example, where the duration corresponds to the difference between the open and close times of the relevant port. By recording the duration of such user activities, it becomes possible to objectively grasp the actual workload of each user, such as how long they performed communication-related activities.

[0035] Figure 4 shows an example of the configuration of activity history information generated by the monitoring unit 130. The activity history information 125 shown in Figure 4 includes five data items: "start time," "duration," "user," "service name," and "terminal." "Start time" indicates the date and time when each user activity started. "Duration" indicates the duration of each user activity (for example, the duration the user attended an online meeting). "User" indicates the name of the user who performed each user activity. "Service name" indicates the name of the online service used in each user activity. "Terminal" indicates the name or identifier of the client terminal 100 on which each user activity was performed. The name or identifier of each client terminal 100 may be stored in the storage device 104 in advance.

[0036] The monitoring unit 130 determines, for example, from the time difference between the first and second entries in the port monitoring result 123 shown in Figure 3, that the port identified by port number "1234" was open for a period of 30 minutes starting at 10:00 on April 1, 2022. The user for these entries is "UserA". The destination URL for these entries, "https: / / onlinemeeting.com", is associated with the service name "Online MTG" in the destination list 121. The first record in the activity history information 125 in Figure 4 shows the history information generated by the monitoring unit 130 for this user activity. Similarly, the monitoring unit 130 determines, from the time difference between the third and fourth entries in the port monitoring result 123 shown in Figure 3, that the port identified by port number "3456" was open for a period of 40 minutes starting at 11:10 on April 1, 2022. The user for these entries is also "UserA". Furthermore, the destination URL for these entries, "https: / / webmeeting.net", is associated with the service name "WebMTG" in the destination list 121. The second record of the activity history information 125 in Figure 4 shows the history information generated by the monitoring unit 130 for this user activity. The monitoring unit 130 records this activity history information on a recording medium. For example, the activity history information may be recorded in a predetermined storage area of ​​the memory 102 or storage device 104, or it may be output to an external database (for example, a database where activity history information collected from multiple client terminals 100 is stored) and recorded there.

[0037] Note that the data configurations shown in Figures 2 to 4 are merely examples. Each of the destination list 121, port monitoring results 123, and activity history information 125 may have additional data items, or may not have some of the data items shown. For example, the destination list 121 may have an additional data item indicating the port number associated with each destination URL (or each online service). Also, the destination of communication by the client terminal 100 may be identified by an IP address instead of a URL.

[0038] <1-3. Processing Flow> Figure 5 is a flowchart showing an example of the flow of communication monitoring processing performed by the client terminal 100 in this embodiment. The illustrated communication monitoring processing can be continuously repeated while the client terminal 100 is operating. In the following description, processing steps will be abbreviated as S (step).

[0039] First, in S101, the monitoring unit 130 monitors packets communicated between the network interface 101 and an external device. If the monitoring unit 130 detects a communication packet, the process proceeds to S103. In S103, the monitoring unit 130 determines whether the destination URL specified in the header of the detected communication packet is included in the predefined destination list 121. If the specified destination URL is not included in the destination list 121, the detected communication packet is not subject to monitoring, and the process returns to S101. If the specified destination URL is included in the destination list 121, the process proceeds to S105.

[0040] In S105 and S107, the monitoring unit 130 determines a change in the state of the port associated with the online service identified by the destination URL of the detected communication packet. For example, if the port changes from a closed state to an open state (S105-YES), the process proceeds to S109, and the monitoring unit 130 records the open time of the port as a port monitoring result. If the port changes from an open state to a closed state (S105-NO, S107-YES), the process proceeds to S111, and the monitoring unit 130 records the closed time of the port as a port monitoring result. If the port that was in an open state remains open (S105-NO, S107-NO), the process returns to S101.

[0041] In S111, the monitoring unit 130 records the port's closing time, and then in S113, calculates the duration of user activity equal to the difference between the port's open time and closing time. Then, in S115, the monitoring unit 130 records the activity history information, including the calculated duration, onto the recording medium.

[0042] <1-4. Summary of the First Embodiment> According to the first embodiment described above, the use of ports for communication with external devices is monitored in the terminal device, and historical information regarding user activity involving the above communication is generated and recorded on a recording medium based on the open time when the port is opened and the close time when the port is closed. Therefore, even if multiple types of applications may be used for user activity in the terminal device, the status of user activity can be understood from the historical information recorded by a general mechanism that is not dependent on a specific application. In other words, organizations such as companies that want to manage the activities of members working remotely can collect historical information on members' activities without forcing them to use a single dedicated system. This is beneficial not only in that it reduces the cost and effort of implementing management functions, but also in that it allows for the flexible use of a variety of convenient applications, thereby contributing to improved efficiency of remote work.

[0043] Furthermore, according to the first embodiment, the port open time and close time are determined based on the state of the port associated with the packet, provided that the destination of the packet being communicated is included in a predefined destination list. In other words, since the state of the port only needs to be determined when a communication packet destined for a predefined destination is detected, monitoring of port usage can be achieved with minimal processing within the terminal device.

[0044] Furthermore, according to the first embodiment, the user activity includes the user's attendance at an online meeting, and the destination list defines at least one destination associated with an online meeting application. For example, a terminal device may be capable of running two or more types of online meeting applications, each of which opens a unique port when a user joins an online meeting and closes that unique port when the user leaves the online meeting. By capturing the open and close times of these ports using a common mechanism, a general-purpose activity tracking function that is not dependent on a specific online meeting application is realized. Since the destination list can define destinations associated with two or more types of online meeting applications, users or administrators can easily expand the scope of activity tracking simply by adding candidate destinations to the destination list.

[0045] <2. Second Embodiment> <2-1. System Configuration> In the first embodiment, an example was mainly described in which a client terminal 100 performs a series of processes from port monitoring to recording activity history information. However, in order to conserve the computing resources of the client terminal, some of these processes may be performed by other devices that communicate with the client terminal. In the second embodiment described below, an example is described in which a server device generates the activity history information.

[0046] Figure 6 is a schematic diagram showing an example of the configuration of the information processing system 2 according to the second embodiment. Referring to Figure 6, the information processing system 2 includes a plurality of application servers 20 (20a, 20b, 20c), a plurality of client terminals 200 (200a, 200b, 200c), and a management server 300.

[0047] Client terminals 200a, 200b, and 200c are terminal devices used by different users. Each client terminal 200 may be any type of information processing device, such as a PC, smartphone, or mobile phone. The management server 300 is an information processing device connected to each client terminal 200 via the network 10. The management server 300 centrally manages historical information regarding user activity involving communication performed on each client terminal 200.

[0048] <2-2. Client Terminal Configuration> As shown in Figure 6 in relation to client terminal 200a, client terminal 200 includes a network I / F 101, memory 102, I / O device 103, storage device 104, and processor 210.

[0049] The processor 210 implements all the functions of the client terminal 200 by executing computer programs stored in memory 102. The processor 210 may include any processing circuit, such as a CPU, microprocessor, or microcontroller. The client terminal 200 may have a variety of functions that a typical user terminal has. However, for the sake of simplicity, only functions related to user activities involving communication with external devices will be described here. Referring to Figure 6, the functions implemented by the processor 210 include multiple applications 120a, 120b, ..., and a monitoring unit 230.

[0050] The monitoring unit 230 is a functional module introduced to manage user activity performed on the client terminal 200. The monitoring unit 230 is implemented as a software module, for example, by the processor 210 executing a corresponding computer program stored in memory 102.

[0051] The monitoring unit 230 monitors the use of ports for communication between the client terminal 200 and external devices, and records the open time when each port is opened and the close time when each port is closed. In this embodiment, the communication monitored by the monitoring unit 230 may be remote access to destinations included in the predefined destination list 121, as explained with reference to Figure 2.

[0052] The monitoring unit 230 determines the open time of the port associated with a packet communicated via the network interface 101, based on the state of that port, if the destination of the packet is included in the destination list 121. Similarly, the monitoring unit 230 determines the close time of the port being monitored, based on the state of that port. The monitoring unit 230 then generates the port monitoring results as explained using Figure 3. The monitoring unit 230 periodically (for example, once every few hours or once a day) or in response to a request from the management server 300, sends the port monitoring results to the management server 300.

[0053] <2-3. Configuration of the Management Server> As shown in Figure 6, the management server 300 includes a network interface 301, memory 302, I / O device 303, storage device 304, and processor 310.

[0054] The network interface 301 is a communication unit for the management server 300 to communicate with other devices via the network 10. The network interface 301 may include either or both a wireless communication interface and a wired communication interface. The memory 302 may be any combination of volatile memory and non-volatile memory. The RAM provides a temporary storage area for calculations performed by the processor 310. The ROM pre-stores computer programs to be executed by the processor 310. Some of these computer programs may be stored in the storage device 304, which will be described later. The I / O device 303 includes an input device for inputting information to the management server 300 and an output device for outputting information from the management server 300. For example, a user with administrator privileges (also called an administrator user) can give various instructions to the management server 300 via the I / O device 303. The storage device 304 is a storage device capable of storing large amounts of data. The storage device 304 may include, for example, an HDD or an SSD. In this embodiment, the storage device 304 stores, for example, the same destination list 121 as stored in each client terminal 200, port monitoring results received from each client terminal 200, and activity history information for each user.

[0055] The processor 310 may include any processing circuit, such as a CPU, microprocessor, or microcontroller. Referring to Figure 6, the functions implemented by the processor 310 include an information recording unit 340. The information recording unit 340 is a functional module introduced for the user activity management function of the management server 300. The information recording unit 340 is implemented as a software module, for example, by the processor 310 executing a corresponding computer program (e.g., a server program) stored in memory 302.

[0056] The information recording unit 340 receives the port monitoring results generated at each client terminal 200 via the network interface 301 and stores the received port monitoring results in the storage device 304. The information recording unit 340 may periodically receive port monitoring results from each client terminal 200. Additionally or alternatively, when the I / O device 303 receives instructions from an administrator user, the information recording unit 340 may send a request to a designated client terminal 200 for the provision of port monitoring results and receive the port monitoring results provided by the client terminal 200 in response to the request.

[0057] The information recording unit 340 analyzes the port monitoring results provided by each client terminal 200 and generates history information regarding user activity performed at each client terminal 200. Specifically, the information recording unit 340 determines that user activity began at the open time when each monitored port was opened and ended at the close time when the port was closed. Based on these port open and close times, the information recording unit 340 generates activity history information as explained with reference to Figure 4. The information recording unit 340 records the generated activity history information on a recording medium. For example, the activity history information may be recorded in a predetermined storage area of ​​the memory 302 or storage device 304, or it may be output to an external database and recorded there.

[0058] <2-4. Processing Flow> Figure 7 is a sequence diagram showing an example of the information recording process performed in this embodiment. The illustrated information recording process involves the management server 300, the application server 20a, and client terminals 200a and 200b. For illustrative purposes, the user of client terminal 200a attends an online meeting hosted by the user of client terminal 200b.

[0059] Prior to the online meeting, in S201, the information recording unit 340 of the management server 300 configures the client terminal 200a to monitor the use of a port for communication with an external device. At this time, the information recording unit 340 may also notify the client terminal 200a of destination entries that should be included in the destination list 121. Note that the port monitoring settings may be performed locally on the client terminal 200a, in which case S201 may be omitted. The client terminal 200b may also be configured to monitor port usage, but for the sake of simplicity, only the monitoring on the client terminal 200a will be described here.

[0060] As the scheduled time for the online meeting approaches, the user on client terminal 200b logs in to client terminal 200b and launches application 120a. Then, in S203, application 120a on client terminal 200b initiates communication for the online meeting by sending a request packet to application server 20a. The request packet sent to application server 20a has, for example, a URL specific to the online meeting service provided by application server 20a as its destination. Application 120a on client terminal 200b sets up the online meeting and waits for other users to join the online meeting.

[0061] The user of client terminal 200a logs in to client terminal 200a and launches application 120a. Then, in S205, application 120a on client terminal 200a initiates communication for the online meeting by sending a request packet to application server 20a. The request packet sent to application server 20a also has a URL specific to the online meeting service provided by application server 20a as its destination.

[0062] In S207, application 120a on client terminal 200a opens the port associated with application 120a. This enables application 120a to receive data distributed from application server 20a or client terminal 200b via network I / F 101. The monitoring unit 230 on client terminal 200a detects that the port associated with application 120a has been opened and obtains the open time. The monitoring unit 230 records the obtained open time in the port monitoring results, associating it with the port number of the port, the username of the logged-in user, and the destination URL.

[0063] Subsequently, in S210, with the support of application server 20a, video, audio, and other data of the online meeting are sent and received between client terminal 200a and client terminal 200b.

[0064] In S221, in response to the I / O device 103 detecting a user's exit operation, the application 120a on the client terminal 200a sends a packet to the application server 20a to notify it that the user has exited. This packet also has a URL specific to the online meeting service provided by the application server 20a as its destination. Next, in S223, the application 120a closes the port that was opened when joining the online meeting. The monitoring unit 230 on the client terminal 200a detects that the port has been closed and obtains the close time. The monitoring unit 230 records the obtained close time in the port monitoring results, associating it with the port number of the port, the username of the logged-in user, and the destination URL.

[0065] In S225, the monitoring unit 230 of the client terminal 200a sends the port monitoring results updated in S207 and S223 to the management server 300. The information recording unit 340 of the management server 300 receives the port monitoring results sent from the client terminal 200a. Next, in S227, the information recording unit 340 generates history information regarding user activity performed on the client terminal 200a based on the port monitoring results received from the client terminal 200a. For example, the information recording unit 340 may calculate the duration of user activity equal to the difference between the open time and the close time described in the port monitoring results, and generate activity history information including the calculated duration. Next, in S229, the information recording unit 340 records the generated activity history information on the recording medium.

[0066] In S231, the application 120a on the client terminal 200b sends a packet to the application server 20a to notify it of the end of the online meeting, for example, in response to the user's action to end the online meeting.

[0067] In this example, the management server 300 is responsible for generating and recording activity history information, which is part of a series of processes from port monitoring to recording activity history information. However, the division of functions between the client terminals 200 and the management server 300 is not limited to this example. For example, each client terminal 200 may generate activity history information and send it to the management server 300, and the management server 300 may record the activity history information received from multiple client terminals 200. Alternatively, each client terminal 200 may generate statistical information (e.g., total daily activity time) from the activity history information and send it to the management server 300, and the management server 300 may record the statistical information received from multiple client terminals 200.
