Description

The present invention relates to a remote operation system for remotely operating a computer terminal (remote operation). More specifically, the present invention relates to a remote operation system in which operation restriction of remote operation is performed according to the state of the operated computer terminal.

  In recent years, many computer terminals are used in organizations such as companies, and are indispensable for business. Computer terminals are widely used even for individuals. As described above, computer terminals are used in various situations, but problems may occur. In this case, it is often dealt with by remote operation.

  In general, during remote operation, the operating computer terminal obtains the operating authority of the operated computer terminal, and the operation screen of the operated computer terminal is displayed on the operating computer terminal. In the remote control process.

  Therefore, it is often possible to operate all of the operated computer terminals from the operating computer terminal. For example, when the computer terminal of an officer of a company is malfunctioning and the system administrator remotely controls the computer terminal of the officer, the system administrator stores all the information stored in the computer terminal of the officer (operated computer terminal) You may be able to access this information.

  However, the officer's computer terminal may contain a lot of confidential information that the system administrator is not allowed to contact. Although the system administrator normally does not permit access to the confidential information due to access restrictions, the system administrator's computer terminal (operating computer terminal) is remotely connected to the officer's computer terminal (operated computer terminal). By executing the operation, the officer's computer terminal can be directly operated, and it is assumed that the access restriction does not function.

  This is not preferred for security, but remote control may be necessary in some cases and depends on the conscience of the system administrator.

  However, there is no denying the possibility that the system administrator can remotely operate the system maliciously. Therefore, assuming such a case, when performing remote operation, a remote control system that copes with different operators monitoring the operation, leaving a system log, and performing predetermined operation restrictions is described in the following patent It is disclosed in Document 1.

JP 2006-108947 A

  In the case of the remote control system disclosed in Patent Document 1, a method has been proposed in which a different operator monitors the operation or leaves a system log when performing a remote operation. Although illegal operations can be tracked, illegal operations themselves cannot be prevented. In other words, there is no choice but to expect a deterrent effect by monitoring and logs.

  Also, a remote operation restriction item table is provided in the server, and for each combination of the user ID of the operated computer terminal and the operator ID of the operating computer terminal, there is a terminal application program that can be used by the operator. It has been proposed to perform operation restriction by storing identification information such as identification information and functions in an application program.

  However, it is not practical to set predetermined operation restrictions according to application programs or the like. This is because it is very difficult to make settings assuming every situation because it is not known what kind of trouble occurs in the computer terminal on the operated side. In addition, the environment of the computer terminal is often different for each computer terminal, and such advance settings often do not make much sense.

  Therefore, in the remote control system of the above-mentioned patent document 1, it is practically difficult to prevent unauthorized operation during remote operation. Therefore, there is a demand for a remote operation system that can perform operation restrictions so that unauthorized operations are not performed during remote operation, and that can be practically operated.

  In view of the above problems, the present inventor has invented a remote operation system that can perform operation restrictions during remote operation and that can be practically operated.

  A first aspect of the present invention is a remote operation system for performing a remote operation on a computer terminal, and the remote operation system is based on operation log information of an operated computer terminal that is an object of remote operation. An operable object determination unit that identifies an application and / or file that is running on a computer terminal, and that determines an application and / or file that satisfies a predetermined condition from among the identified application and / or file as an operable object; The remote operation system includes a remote operation processing unit that enables remote operation of the operable computer terminal of the operated computer terminal and executes remote operation processing.

  According to the configuration of the present invention, it is possible to perform remote operation on an application or file that is activated on the operated computer terminal and satisfies a predetermined condition. This eliminates the need to set operations for restricting operations in advance as in the case of conventional remote operation control, and also allows remote operations to be performed because the remote operation target can be operated as it is. It becomes. Accordingly, it is possible to perform a remote operation that can be practically operated and solves a security problem.

  The predetermined condition may be, for example, an application or file for which a predetermined operation has been performed, an application or file that is being used, or the like. Here, the predetermined operation includes, for example, whether a specific operation has been performed or whether an alert has occurred. For example, the active application or file, the application or file in the latest operation log information, the application or file that has been operated for the longest time, the application or file that has been active for the longest time, or the operation Examples are the application and file that are displayed the largest in the screen information. However, the present invention is not limited to these.

  The above-described invention may be configured as the following invention. That is, a remote operation system that performs a remote operation on a computer terminal, the remote operation system from a storage area that stores operation log information of an operated computer terminal that is an object of remote operation, An operation log information acquisition unit that acquires operation log information of a computer terminal, and an application and / or file that is running on the operated computer terminal based on the acquired operation log information, and the specified application And / or an operable target determination unit for determining an application and / or file satisfying a predetermined condition as an operable target among files, and remote operation of the operable target of the computer terminal on the operated side is enabled. A remote control processing unit for executing remote control processing It may be configured as that the remote control system.

  The remote operation system in the above-described invention can be realized by reading and executing the remote operation program of the present invention on a computer terminal. That is, the operating computer terminal that performs remote operation is identified based on the operation log information of the operated computer terminal that is the target of remote operation, and the application and / or file that is running on the operated computer terminal is identified. An operable target determining unit that determines an application and / or file satisfying a predetermined condition as an operable target among the identified applications and / or files, and remote operation of the operated computer terminal with respect to the operable target It may be configured as a remote operation program that enables operation and functions as a remote operation processing unit that executes remote operation processing.

In the conventional remote operation system, it is necessary to set a predetermined operation restriction according to an application program or the like, but such a prior setting is not required by the remote operation system of the present invention. Further, since the remote operation is restricted according to the operation state on the operated side, a remote operation system that can be practically operated is obtained.

  An example of an overall conceptual diagram of the remote control system 1 of the present invention is shown in FIG. An example of a conceptual diagram of the system configuration of the remote operation system 1 is shown in FIG.

  The remote operation system 1 of the present invention shows a case where the system is implemented by one administrator terminal 4 in FIG. 2, but each function of the system is distributed and arranged in a plurality of computer terminals (including servers). In addition, the processing may be realized by a plurality of computer terminals and servers.

  The remote operation system 1 of the present invention includes a computer program or a server (hereinafter referred to as “manager terminal 4”) used by an administrator who remotely operates a client terminal 3 that is a target of remote operation. This is realized by processing. Therefore, in the client terminal 3, information such as a program and a file executed in the client terminal 3 is periodically or at a predetermined timing such as when a new program or file is executed or terminated. A function of transmitting information such as programs and files from the terminal 3 to the management server 2 and a screen displayed on the display device 22 of the client terminal 3 are captured, and the management server 2 and the administrator terminal 4 are regularly or irregularly captured. It is preferable to have a function of transmitting to the network. The function of transmitting information such as a program or file can be extracted by extracting information such as a program or file being executed by the computing device 20 of the client terminal 3, or by extracting information such as a program or file in the memory. That's fine. That is, so-called operation log information may be transmitted from the client terminal 3 to the management server 2. In order to capture the operation screen displayed on the display device 22, for example, the displayed operation screen information is read from a display information storage device that stores information to be displayed on the display device 22 such as a VRAM, and the operation screen information is operated. What is necessary is just to transmit as screen information.

  The operation log information and the operation screen information may be associated with each other at the same time or may not be associated with each other. The operation log information and the operation screen information may be transmitted from the client terminal 3 to the management server 2 at the same timing, or may be transmitted at different timings.

  The management server 2, the administrator terminal 4, the client terminal 3, and the like include an arithmetic device 20 such as a CPU that executes program arithmetic processing, a storage device 21 such as a RAM or a hard disk that stores information, and processing results of the arithmetic device 20. And a communication device 24 that transmits and receives information stored in the storage device 21 via a network such as the Internet or a LAN. Each function (each unit) realized on the management server 2, the administrator terminal 4, and the client terminal 3 is executed when a unit (program, module, etc.) that executes the process is read into the arithmetic unit 20. The When using the information stored in the storage device 21 in the processing, each function reads the corresponding information from the storage device 21 and uses the read information for processing in the arithmetic device 20 as appropriate. Further, the management server 2, the administrator terminal 4, the client terminal 3, and the like may further include a display device 22 such as a display and an input device 23 such as a keyboard, a mouse, and a numeric keypad. FIG. 3 schematically shows an example of the hardware configuration of the computer terminal.

  Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area.

  The client terminal 3 is a computer terminal used by the user, and has a function of transmitting the above-described operation log information, a function of transmitting operation screen information, and the like. Further, it has a remote operation function, receives a remote operation instruction from the administrator terminal 4, executes processing corresponding to the instruction, and displays operation screen information to be displayed on the display device 22 of the client terminal 3. 4 (may also be sent to the management server 2). Based on the operation screen information transmitted here, the administrator of the administrator terminal 4 who performs the remote operation can check what kind of display is performed on the client terminal 3.

  The management server 2 is a server that receives and stores operation log information from each client terminal 3. In response to an inquiry from the administrator terminal 4, the corresponding operation log information is retrieved and transmitted to the administrator terminal 4.

  The operation log information may be information indicating the operation content in the client terminal 3, the processing content in the client terminal 3, and the like. For example, “file copy”, “file selection”, “drive addition”, “pointing device operation” , “Screen control (window size change, scroll, etc.)”, “print”, “copy”, “paste”, and the like indicate information indicating the operation of the user of the client terminal 3. The operation log information includes information for identifying the client terminal 3 (computer name and the like), information for identifying the user (login name and the like), information indicating the operation content, the name of the file or application that is the operation target, the file, It includes information indicating the storage location of the application, date and time, or information obtained by digitizing the date and time. FIG. 5 shows an example of operation log information. The operation log information is preferably stored for each client terminal 3 or its user (login name or the like). In addition, when associating the information indicating the operation content with the date and time, it may be performed at the client terminal 3, when the operation log information is acquired by the management server 2, or stored in the management server 2. You may go when you do.

  The administrator terminal 4 is a computer terminal used by an administrator who remotely operates the client terminal 3. Further, the administrator terminal 4 has a function of controlling a remote operation, and uses the operation screen information acquired from the client terminal 3 and the operation log information acquired from the management server 2 or the client terminal 3. The remote operation processing in the remote operation system 1 is executed. The administrator terminal 4 may be provided integrally with the management server 2 or may be provided as a separate computer terminal.

  The remote operation system 1 includes an operation log information acquisition unit 5, an operable target determination unit 6, and a remote operation processing unit 7.

  The operation log information acquisition unit 5 uses the administrator terminal 4 to request remote operation of the client terminal 3 and identification information of the client terminal 3 that is the target of remote operation (or identification information of a user who operates the client terminal 3). Is received, the operation log information corresponding to the identification information of the client terminal 3 (or the identification information of the user who operates the client terminal 3) is acquired from the management server 2 or the client terminal 3.

  When acquiring the operation log information, all the operation log information stored in the management server 2 or the client terminal 3 may be transmitted, but preferably, until a predetermined time (for example, 10 minutes before). It is good to acquire operation log information. Or you may make it acquire only the newest operation log information (when the 1st determination method is used in the operation possible object determination part 6 mentioned later).

  When the operation log information acquisition unit 5 acquires the operation log information of the client terminal 3 that is the target of remote operation, the operable target determination unit 6 performs a remote operation from the administrator terminal 4 based on the operation log information. Only the applications and files that are active on the client terminal 3 that is the target of remote operation, for example, the target of remote operation (first determination method), or the client that is the target of remote operation Among the applications and files running on the terminal 3, it is determined that only applications and files for which a specific operation is performed are targeted for remote operation (second determination method).

  The first determination method will be described.

  FIG. 6 schematically shows an example of operation log information acquired by the operation log information acquisition unit 5 from the management server 2 or the client terminal 3 that is a target of remote operation. In the case of the first determination method, only the application or file that is active on the client terminal 3 that is the target of remote operation is determined as the target of remote operation, so the most recent operation log among the acquired operation log information By determining the application or file in the information (the latest operation log information can be specified by the date / time information in the operation log information), it becomes possible to determine the application or file to be remotely operated. When the operation log information includes active / inactive switching information, an active application or file can be specified based on the operation log information. In addition, as a method to identify the active application (active) and file name, start such as “Start”, “End”, “File open”, “File close” in the operation contents of the operation log information By determining whether or not information indicating the state is included, it is possible to determine a running application and a file name.

  For example, when the operation log information is shown in FIG. 6, the latest operation log information is a “print” operation for the file “order book” of the application “word processing software C”. Therefore, the operable target determination unit 6 determines that only remote operation is possible for the file “order book” of the application “word processing software C”. At this time, it may be determined that only the remote operation for the application “word processor software C” is possible (the file name is not limited. Therefore, if the application is “word processor software C”, the file “order” Other files can also be remotely controlled). This determination process is schematically shown in FIG.

  Problems with computer terminals are likely to occur for applications and files currently used. That is, applications and files currently used are often active in computer terminals. Therefore, as in the first determination method, the remote operation can be performed only on the application or file in the active state, so that the problem can be solved, and the client terminal 3 on the operated side can be operated. On the other hand, since unnecessary operations cannot be performed from the administrator terminal 4 on the operation side, security problems can be solved. In such a case, the first determination method is effective.

  Next, the second determination method will be described.

  In the case of the second determination method, among the applications and files that are activated on the client terminal 3 that is the target of remote operation, only the application or file that is performing a specific operation is determined as the target of remote operation. Among the acquired operation log information, the operation log information whose operation content is a “specific operation” that is set in advance is specified. Then, by determining the application or file in the specified operation log information, it becomes possible to determine the application or file to be remotely operated.

  For example, it is assumed that the operation log information is in FIG. 6 and “print”, “copy”, and “paste” are set as specific operations. The specific operation is stored in advance in the administrator terminal 4 as shown in FIG. In this state, the operable target determination unit 6 identifies operation log information whose operation contents are “print”, “copy”, and “paste” among the operation log information acquired by the operation log information acquisition unit 5. . Then, the operation content is “Copy”, the operation log information of the application “Spreadsheet Software A” and the file “Customer Information”, and the operation content is “Paste” and the operation log of the application “Spreadsheet Software A” is the file “Customer Information”. The operation log information of the file “Purchase Order” is specified by the application “Word Processor Software C” with the information and operation content “print”.

  When the operation log information is specified in this way, the operable target determination unit 6 determines the file “customer information” and the application “word processing software” of the application “spreadsheet software A” based on the application name and file name of the operation log information. It is determined that only the remote operation for the file “Order Form” of “C” is possible. At this time, it may be determined that only remote operation for the applications “spreadsheet software A” and “wordprocessor software C” is possible (the file name is not limited. Therefore, “spreadsheet software A” or “word processor software”). If it is an application of “Software C”, files other than the files “Customer Information” and “Order Form” can be remotely operated. This determination process is schematically shown in FIG.

  Problems with computer terminals are more likely to occur when specific operations are performed in addition to applications and files currently used. Therefore, as in the second determination method, the remote operation can be performed only on the application or file for which a specific operation has been performed, so that the problem can be solved, and the operated client terminal 3, since unnecessary operations cannot be performed from the administrator terminal 4 on the operation side, security problems can be solved. In such a case, the second determination method is effective.

  In addition, although the 1st determination method and the 2nd determination method were demonstrated as determination in the operable object determination part 6, other determination methods can also be used. In other words, a method of remote-controlling only applications and files that are active on the client terminal 3 that is the target of remote operation, among applications and files that are running on the client terminal 3 that is the target of remote operation, You may use methods other than the method which makes only the application and file in which specific operation is performed the object of remote operation.

  For example, it may be determined that among the applications and files running on the client terminal 3 that is the target of remote operation, the applications and files that are being used are set as targets of remote operation (third determination method). .

  In the case of the third determination method, in addition to the above-described second determination method, the latest operation log among the operation log information acquired by the operation log information acquisition unit 5 is used as the determination of the application or file being used. The application log and the file in the information are determined, and the operation log information is classified for each application and file among the operation log information acquired by the operation log information acquisition unit 5, and the application or file operated for the longest time is determined. (Time can be calculated from the date and time information in the operation log information), among the operation log information acquired by the operation log information acquisition unit 5, the operation log information is classified for each application and file, and the application that has been active for the longest time Determine file (active in operation log information It is possible to calculate the time by the date and time information in the case of the operation log information), and the like. In addition, it is possible to determine the application or file that is displayed in the largest size in the operation screen information of the operated client terminal 3 as the application or file being used. This is because the coordinate information of each application and file is managed by the window manager of the client terminal 3 on the operated side, and is acquired by the administrator terminal 4 (the coordinate information is included in the operation log information). Or may be acquired separately), and processing is possible by calculating the area based on the coordinate information.

  The remote operation processing unit 7 executes processing when the operated client terminal 3 is remotely operated from the manager terminal 4 on the operation side. The remote control process itself is the same as a normal remote control. That is, for remote operation with the client terminal 3 based on the identification information of the client terminal 3 to be remotely operated (or the IP address or MAC address specified based on the identification information of the client terminal 3). And obtains the operation authority from the client terminal 3. Based on the operation authority, operation screen information to be displayed on the display device 22 of the client terminal 3 is acquired from the client terminal 3 periodically or at a predetermined timing, and the acquired operation screen information is acquired from the administrator terminal 4. Are displayed on the display device 22. While browsing the operation screen information, the administrator performs an operation input to the client terminal 3 from the input device 23. In addition, it is determined whether the operation input here is an operation for an operable application or file determined by the operable object determination unit 6, and in the case of an operation for an operable application or file, the input operation Is transmitted from the administrator terminal 4 to the client terminal 3, and the client terminal 3 that has received it transmits the processing corresponding to the operation. When the input operation is not an operation for an operable application or file, the input operation is not transmitted from the administrator terminal 4 to the client terminal 3. In this case, when an operation other than an operable application or file is performed, the client terminal 3 is notified that an operation other than the input operable application or file has been performed, When permission is selected for the notification, the client terminal 3 can be configured to execute operations other than operable applications and files.

  Here, a case has been described in which the remote operation processing unit 7 determines whether the operation input on the administrator terminal 4 is an operation with respect to an operable application or file. The client terminal 3 may be used. That is, when the network connection for remote operation is established between the administrator terminal 4 and the client terminal 3 and the operation authority is acquired from the client terminal 3, the remote operation processing unit 7 determines with the operable object determination unit 6 Information on applications and files that can be operated from the administrator terminal 4 (in addition to application names and file names, information on storage locations of applications and files may be included. Information on storage locations is specified from operation log information. Can be transmitted to the client terminal 3 and stored in the client terminal 3. The remote operation processing unit 7 transmits the operation input from the administrator terminal 4 to the client terminal 3 from the administrator terminal 4. Upon receiving this operation, the client terminal 3 determines whether the received input operation is an operation for an operable application or file, and if it is determined that the input operation is an operation for an operable application or file, the client terminal 3 In step 3, a process corresponding to the operation is executed. If it is determined that the input operation is not an operation for an operable application or file, the received operation is not executed.

  The determination as to whether the input operation is an operation with respect to an operable application or file is based on position information and operation instructions (“file open”) of the input device 23 (pointing device such as a mouse or keyboard) when executing the operation. The application name and file name selected as the processing target or the storage location information is specified based on the application name or file name of the application or file, etc. It is determined whether or not the information matches the storage location information, and if it matches, it is determined that the operation is for an operable application or file. When the determination is made based on the position information, the application or file existing in the position information is the application or file selected as the processing target.

  When the remote operation processing unit 7 performs remote operation on the application or file determined as the target of remote operation in the operable target determination unit 6, only the determined application or file may be the target of remote operation, or the determined application Applications and files used for files and files may also be automatically subject to remote operation.

  For example, when it is determined that an application of a certain word processing software is a target of remote operation, the “printing function” application used in the word processing software is a part of the OS function, and printing is performed by the word processing software. In this case, it is assumed that the function is called. In this case, if only the application or file determined by the operable target determination unit 6 is a target for remote operation, it is possible to use another application or file used (or incorporated) in the word processing software as described above. Remote control will not be possible for functions to be realized. Therefore, it is preferable that other applications and files used in applications and files determined as remote operation targets in the operable object determination unit 6 are automatically determined as remote operation targets. That is, it is preferable that an application or a file related to an application or a file determined as a remote operation target is a remote operation target.

  Next, an example of the processing process of the remote operation system 1 of the present invention will be described with reference to the flowchart of FIG. 4 and the conceptual diagram of FIG.

  The operation log information of the client terminal 3 is transmitted from the client terminal 3 to the management server 2 periodically or at a predetermined timing. This operation log information is stored in the management server 2. In general, the operation log information includes information for identifying the client terminal 3 and date and time information. If the operation log information is not included, the operation log information is acquired together. , Store them in association with each other.

  Then, for some reason, for example, when a malfunction or restricted operation (predetermined operation, etc.) occurs in the client terminal 3 or a remote operation request is generated from the operated client terminal 3, the remote operation of the client terminal 3 is performed. When performing from the administrator terminal 4, the administrator selects the client terminal 3 that performs remote operation from the administrator terminal 4 and starts remote operation (for example, presses a remote operation start icon on a predetermined screen). ). By this operation, the administrator terminal 4 receives a request for starting a remote operation (S100).

  As a result, the operation log information acquisition unit 5 acquires the client terminal identification information of the selected client terminal 3 (or the identification information of the user who operates the client terminal 3), and sends the client terminal identification information to the management server 2. By transmitting information (or identification information of the user who operates the client terminal 3), operation log information or latest operation log information for a predetermined time in the client terminal 3 is acquired from the management server 2 (S110). .

  Then, based on the operation log information acquired by the operation log information acquisition unit 5, the operable object determination unit 6 can be remotely operated from the administrator terminal 4 by the administrator using the first determination method or the second determination method described above. A possible application or file is determined (S120).

  In this way, when the administrator determines an application or file that can be remotely controlled by the administrator, the remote operation processing unit 7 selects the client terminal 3 and the administrator terminal 4 that are selected as targets for remote operation. Establishes a network connection for remote operation, and starts remote operation processing (S130).

  Specifically, by receiving operation screen information from the client terminal 3 to be remotely operated and displaying it on the display device 22 of the administrator terminal 4, the administrator performs an operation input from the input device 23. Then, it is determined whether the operation input is an operation that can be remotely operated. If the operation input is an operation that can be remotely operated, the client terminal 3 executes the operation.

  By executing the processing as described above, the remote operation of the client terminal 3 can be executed, and operations other than the operation determined as an operation that can be remotely operated cannot be executed on the client terminal 3, and thus security can be maintained. It becomes.

  In the first embodiment described above, the operation log information of the client terminal 3 is stored in the management server 2. However, in the present embodiment, the operation log information of the client terminal 3 is stored in the client terminal 3. Will be explained.

  Also in the present embodiment, when a remote operation of the client terminal 3 is performed from the administrator terminal 4 due to some reason, for example, a problem occurs in the client terminal 3, the administrator performs the remote operation from the administrator terminal 4. The client terminal 3 to be performed is selected and the remote operation is started (for example, the start icon of the remote operation is pressed on a predetermined screen). By this operation, the administrator terminal 4 receives a request for starting a remote operation (S100).

  Thereby, the operation log information acquisition unit 5 acquires the client terminal identification information of the selected client terminal 3 (or the identification information of the user who operates the client terminal 3), and from the client terminal 3 having the client terminal identification information. The operation log information for the predetermined time or the latest operation log information is acquired (S110).

  Then, based on the operation log information acquired by the operation log information acquisition unit 5, the operable object determination unit 6 can be remotely operated from the administrator terminal 4 by the administrator using the first determination method or the second determination method described above. A possible application or file is determined (S120).

  In this way, when the administrator determines an application or file that can be remotely controlled by the administrator, the remote operation processing unit 7 selects the client terminal 3 and the administrator terminal 4 that are selected as targets for remote operation. Establishes a network connection for remote operation, and starts remote operation processing (S130).

  Specifically, by receiving operation screen information from the client terminal 3 to be remotely operated and displaying it on the display device 22 of the administrator terminal 4, the administrator performs an operation input from the input device 23. Then, it is determined whether the operation input is an operation that can be remotely operated. If the operation input is an operation that can be remotely operated, the client terminal 3 executes the operation.

  In the present embodiment, the case where the functions of the management server 2 and the administrator terminal 4 are substantially integrated, and the case where the function of the management server 2 is provided in the administrator terminal 4 will be described. That is, a case where operation log information of the client terminal 3 is stored in the administrator terminal 4 will be described. In the case of this embodiment, the administrator terminal 4 includes an operation log information storage unit (not shown) that stores operation log information acquired from each client terminal 3.

  Also in the present embodiment, when a remote operation of the client terminal 3 is performed from the administrator terminal 4 due to some reason, for example, a problem occurs in the client terminal 3, the administrator performs the remote operation from the administrator terminal 4. The client terminal 3 to be performed is selected and the remote operation is started (for example, the start icon of the remote operation is pressed on a predetermined screen). By this operation, the administrator terminal 4 receives a request for starting a remote operation (S100).

  Thereby, the operation log information acquisition unit 5 acquires the operation log information from the operation log information storage unit based on the client terminal identification information of the selected client terminal 3 (or the identification information of the user who operates the client terminal 3). (S110).

  Then, based on the acquired operation log information, the operable target determination unit 6 determines an application or file that can be remotely operated by the administrator from the administrator terminal 4 using the first determination method or the second determination method described above. (S120).

  In this way, when the administrator determines an application or file that can be remotely controlled by the administrator, the remote operation processing unit 7 selects the client terminal 3 and the administrator terminal 4 that are selected as targets for remote operation. Establishes a network connection for remote operation, and starts remote operation processing (S130).

  Specifically, by receiving operation screen information from the client terminal 3 to be remotely operated and displaying it on the display device 22 of the administrator terminal 4, the administrator performs an operation input from the input device 23. Then, it is determined whether the operation input is an operation that can be remotely operated. If the operation input is an operation that can be remotely operated, the client terminal 3 executes the operation.

  Each function of the remote operation system 1 of the present invention may be appropriately distributed in the client terminal 3, the management server 2, and the administrator terminal 4.

  Note that there are various patterns of variations in the distributed arrangement, and any arrangement form may be used. In these cases, when using functions of another computer terminal or server during processing in the client terminal 3, the administrator terminal 4, or the management server 2, an inquiry is made to the other computer terminal or server. The result is received and used for processing. Then, the processing result is executed.

The remote operation system 1 of the present invention eliminates the need for presetting operation restrictions according to application programs and the like, which are necessary in the conventional remote operation system 1. In addition, since the remote operation is restricted according to the operation state on the operated side, the remote operation system 1 that can be practically operated is obtained.
