Among the file configurations that existed on the day and time, transition information consisting of information files that differ from the file configuration of the current date and time, and information that has operated the files such as “delete” and “move” as the information that has led to the difference It has a structure in which displayed file confirmation areas 64 are arranged in parallel vertically.

  In the present embodiment, processing related to information that has resulted in differences in information files is described, but the present invention is not intended to process only the file structure included in the directory, and processes folders included in the directory. It is included in the subject. Since the processing target includes a folder in this way, if it differs from the folder existing at the current date and time among the folders existing at the past date and time specified in the directory, it has become different from the different folder. As information, transition information including character information such as “delete” and “move” is displayed. Note that when a folder and an information file are mixed in the directory, processing is performed for the folder and the information file. When they are different at different dates, transition information is displayed for the folder and the information file. .

  Information displayed in the file display area 54 and the file confirmation area 64 is acquired from the management server A. In the management server A, when information specifying the storage directory and information specifying two different dates and times are received from the communication terminal C, the file configuration existing at the specified date and time in the specified directory is already stored. If it is obtained from the obtained operation log and it is determined that there is a difference in the file structure of the two specified dates and times, the information leading to the difference is specified, and the transition information corresponding to the specified situation is acquired. Processing to transmit to the communication terminal C is performed.

  In this embodiment, the processing mode in the situation where the current date and the previous date and time are specified as different dates and times will be described. However, as the different date and time, a past date and a past date and time may be specified. It is also possible to specify three or more dates as different dates. The configuration for realizing these processes and the control mode will be described below.

[Management server]
The management server A includes an information transmission / reception unit 21 that transmits / receives information to / from the communication network L, and an operation screen acquisition unit 22A that acquires an operation screen G from operation information received by the information transmission / reception unit 21; A history acquisition unit 22 including an operation log acquisition unit 22B for acquiring a log is provided, and a memory or a hard disk is stored so as to store history information acquired by the history acquisition unit 22 (superordinate concept of the operation screen G and operation log).

And a management screen generation unit 24.

  The history information storage unit 23 has a function of storing the operation screen G acquired by the history acquisition unit 22 in association with an operation log. In this example, the function is stored in association with each other, but the association may be performed by date information or the like and may be explicitly associated. Further, the association may be performed when the association becomes necessary. The operation log includes information indicating the contents of the operation performed by the operator at the communication terminal C. This operation log includes the directory and the information file when the communication terminal C is connected to the storage directory or information file. Operation information (information such as movement and change) and information (for example, directory name (folder name), file name, attribute information, update information, etc.) that can specify the directory and information file. Further, the history information storage unit 23, when requested from the communication terminal C, determines whether or not a directory exists at a specified date and time, and if a directory exists, sets the folder and file structure included in the directory. It has a function of acquiring specific information that can specify an included file.

  The storage directory information stored in the history information storage unit 23 and the information that can specify the file structure are assumed to be acquired from the operation log as described above. For example, a storage may be accessed and acquired directly from the storage.

  The management server A includes a specific information acquisition unit 25 (an example of a specific information acquisition function), a transition information acquisition unit 26 (an example of a transition information acquisition function), and an information transmission unit / information display unit 27 (an information transmission function / information An example of a display function) and an information specifying unit X are provided.

  The specific information acquisition unit 25 designates a storage directory from the communication terminal C and, based on an operation log saved in the history information saving unit 23, is given information specifying a different date and time. In the designated directory, the file name, attribute information, and update information of the information file included in the file structure at the designated date and time are acquired as specific information. A specific processing form in the specific information acquisition unit 25 will be described in [File display processing] described later.

  When the transition information acquisition unit 26 determines that the file configurations are different at different dates and times by comparing the specific information in the directories at different dates and times acquired by the specific information acquisition unit 25, the transition information acquisition unit 26 makes a difference. Information is acquired as transition information from the history information (superordinate concept of the operation screen G and operation log) of the history information storage unit 23.

  As a specific example of this transition information, as described above, in the file confirmation area 64 of the file display screen 50 shown in FIG. 3, an information file that can be grasped as a difference from the current file configuration, “delete”, “move”, etc. It consists of character information. Further, an operation screen corresponding to the information leading to the difference is acquired as the transition information, and is displayed on the reproduction screen 70 shown in the figure at a position near the operation screen. The file display screen 50 displays an information file icon, a file name, and file attribute information.

  As a specific example when the file configurations at different dates and times are different, the information file included in the past file configuration is not included in the current file configuration, or conversely, the information included in the current file configuration If the file is not included in the past file structure, the information file included in the current file structure and the past file structure can be cited as an example. Deletion, movement of information file, editing of information file, etc. can be considered.

  The information transmission unit / information display unit 27 has a function of transmitting the specific information and the transition information to the communication terminal C or displaying it on its own management monitor.

  The information specifying unit X functions to specify a storage directory and specify a different date and time in the management server A. Specifically, the information specifying unit X differs from the directory specification for the management monitor 5. A dialog for specifying the date and time is displayed, and processing for giving the information input in the dialog to the history information storage unit 23 is performed.

Furthermore, the management server A includes a GUI unit 29 that realizes input of operation information while reflecting operation information from the keyboard 3 and mouse M on the server monitor 2.

  The operation screen acquisition unit 22A, the operation log acquisition unit 22B, the management screen generation unit 24, the specific information acquisition unit 25, the transition information acquisition unit 26, and the information transmission unit / information display that constitute the history acquisition unit 22 The unit 27 and the information specifying unit X are configured by software, but may be configured by a combination of software and hardware, or may be configured only by hardware combining logic and the like. good.

[Management terminal]
The management terminal B includes an information processing unit 33 that accesses information with an information transmission / reception unit 32 that transmits / receives information to / from the communication network L, and displays processed information on the management monitor 5. A GUI unit 34 is provided which implements input to the information processing unit while reflecting operation information from the mouse M or the like on the management monitor 5.

  In FIG. 2, the management terminal B receives processing information in the management server A and displays it on the management monitor 5. However, the management terminal B includes a part of the configuration shown in FIG. A part of the processing may be performed by the server A, and the remaining part of the processing may be performed by the management terminal B.

  The information processing unit 33 is configured by software, but may be configured by a combination of software and hardware, or may be configured only by hardware combining logic and the like. .

[File display processing]
In this information management system, processing is performed according to the flowchart shown in FIG. That is, when a storage directory is specified in the information specifying unit 16 of the communication terminal C and a date and time different from the current date and time before this is specified, this information is transmitted from the information transmitting / receiving unit 15 via the communication network L. It is transmitted to the management server A (Step # 101).

  The information specifying unit 16 displays an input dialog (not shown) on the monitor 8 of the communication terminal C. In this input dialog, the operator arbitrarily specifies a storage directory and arbitrarily specifies a different date and time. The operation is permitted and the input information is transmitted to the management server A.

  In the management server A, the information management program provided in the management server A sets display information based on information from the communication terminal C (step # 200). This processing can be shown as shown in the flowchart of FIG.

  In other words, the management server A receives information from the communication terminal C via the information transmission / reception unit 21 so that the specific information acquisition unit 25 has a new date and time (current date and time in the embodiment) among the specified date and time. The directory file configuration specifying information in the directory is acquired from the operation log stored in the history information storage unit 23 and set in the display information, and the directory file configuration specifying information at the oldest date and time among the specified date and time Is acquired from the operation log stored in the history information storage unit 23 (steps # 201 and # 202).

As processing for acquiring this specific information, the specific information acquisition unit 25 searches the history information stored in the history information storage unit 23 for information related to the specified directory (for example, based on the directory name). Filtering). As a result of this search, the specified 2 based on the information when the information file is generated in the directory, the information when the information file existing in the directory is deleted, the information on the access to the information file in the directory, etc. Specific information that can specify an information file existing in the directory at one date and time is acquired. This specific information includes the file name of the information file, attribute information, and update information.
From

  In particular, when acquiring the specific information of the current information file included in the file structure of the directory specified in this way, connect to the storage, and specify the specific information of the information file included in the file structure of the directory from this storage. You may employ | adopt the processing form to acquire.

  Next, the acquired two types of specific information are given to the transition information acquisition unit 26. The transition information acquisition unit 26 compares the two types of specific information, and if the number of information files is different, the contents of the information file are A difference is determined when different. If it is determined that there is a difference, transition information indicating a different situation is acquired from the operation log stored in the history information storage unit 23, and this transition information is set as display information. The transition information acquisition unit 26 further acquires a corresponding operation screen G from the history information storage unit 23 as transition information corresponding to a different situation, and sets it in the display information (steps # 203 to # 206).

  In this process, the transition information acquisition unit 26 compares the specific information acquired by the specific information acquisition unit 25 to determine whether there is a difference. As an example of the difference, when it is determined that the number of information files is different, an operation log corresponding to the specific information is acquired from the history information storage unit 23 based on the specific information of the information file that exists only on one side. Based on the operation log, transition information indicating a situation that leads to a difference is generated. Further, as the transition information indicating the situation leading to the difference, a multi-frame operation screen G indicating the situation leading to the difference is acquired from the history information storage unit 23.

  That is, the transition information acquired from the operation log is composed of character information such as “delete” and “move” as shown in FIG. 3, and the transition information acquired from the operation screen G is an image in which information indicating the difference is displayed in the form of a moving image. Consists of information.

  The display information set in this way is transmitted to the communication terminal C that has requested this process, and the communication terminal C monitors the information excluding the operation screen G from the display information transmitted from the management server A. (Steps # 206 and # 102).

  In this process, the file display screen 50 shown in FIG. As described above, the file display screen 50 has a structure in which the file display area 54 and the file confirmation area 64 are arranged in parallel vertically. In the file display area 54, icons Fb, file names, and attribute information corresponding to all information files included in the currently existing file structure in the specified directory are listed and displayed in the file display area 54. In the file confirmation area 64, an icon Fc of a past information file not included in the current file configuration among information files included in the file configuration existing at the specified past date in the specified directory is set as the file name. Displayed together with the attribute information, and further, in the vicinity thereof, character information such as “delete” and “move” is displayed as transition information indicating a situation leading to a difference. A scroll bar 54S is formed on the side of the file display area 54, and a scroll bar 64S is formed on the side of the file confirmation area 64.

  By adopting such a display form, by displaying only past information files that do not exist in the current file configuration in the file confirmation area 64, it is possible to easily grasp information files that do not exist at present visually. The situation when the information file that does not exist now disappears can be grasped by the character information.

  Next, when the user selects and clicks the icon Fc displayed in the file confirmation area 64 with the cursor Cu, a reproduction screen 70 is displayed, and the internal area of the display frame E of the reproduction screen 70 is displayed. The operation screen G indicating the situation in which the clicked icon Fc is different is displayed as a moving image so that the situation at the time of disappearance can be grasped visually, and this display continues until the operator ends (# 103- # 105 steps).

  Information for identifying the communication terminal C is displayed on the information display section Ea of the display frame E, and based on this identification information, it is possible to identify the communication terminal C and the operator who deleted or moved the information file. Yes.

[Another Embodiment of File Display Processing]
As the file display screen 50, as shown in FIG. 6, a screen that displays the current file configuration in the storage in comparison with the past file configuration may be used.

  That is, an address bar 51, a plurality of tool icons 52, and the like are arranged in the upper part, and a file designation area 53 (tree view) and a file display area 54 are arranged in the lower position, and on the right side thereof. As a file confirmation unit 60, a search date / time input area 61 for inputting a search date / time at an upper position, an OK button 62 corresponding to the search date / time, a cancel button 63, and a past file configuration are displayed below the file confirmation unit 60. The file confirmation area 64 is arranged. Further, in this lower position, a date change button 65 for confirming the file structure of the previous day and the next day based on the date input in the search date input area 61 and the time input in the search date input area are used as a reference. A time change button 66 is arranged to confirm the file structure one hour before and after one hour.

  A scroll bar 54S is formed on the side of the file display area 54, and a scroll bar 64S is formed on the side of the file confirmation area 64.

  In this file display screen 50, the user inputs information into the address bar 51, operates the icon 52 with the cursor Cu, or selects one of the folders displayed in the file designation area 53 by operating the mouse M. By specifying with Cu, it is possible to specify a predetermined directory of the storage, and an icon corresponding to the file structure of the specified directory is displayed in the file specification area 53 in a tree format, and the information file includes The corresponding icon Fb, file name, and attribute information are displayed in the file display area 54, and the file name and the like are further displayed in the vicinity of the icon Fb.

  In this file display screen 50, it is assumed that the display is performed based on the specific information acquired by the specific information acquisition unit 25 from the operation log stored in the history information storage unit 23. Specific information of an information file included in the file structure of a specified directory may be acquired and displayed in the file display area 54.

  When the user inputs past date information to the search date input area 61 and selects and clicks the OK button 62 with the cursor Cu, the specified past date information and directory Is transmitted to the management server A. Based on the information transmitted in this way, the specific information acquisition unit 25 transmits the specific information at the designated past date and the transition information (character information and the operation screen G) to the communication terminal C. As a result, the file In the confirmation area 64, an icon Fc corresponding to an information file existing at the designated past date and time, a file name, and attribute information are displayed.

  In this display, the icon Fc of the information file that has existed in the past is displayed. For the information file corresponding to the icon Fb of the current information file (the file name and the attribute information match), the file display area 54 is displayed. Is displayed at a position parallel to the information file icon Fb.

  Further, by comparing the current information file with the past information file, information files that exist only on one side are not displayed in parallel. In particular, as shown in FIG. 6, when there is a past information file, but there is no corresponding information file as the current information file, an information file icon Fx is displayed in the file display area 54. As transition information, information on the date and time when the information file was deleted is displayed in the vicinity of the icon Fx. Note that since the icon Fx does not currently exist, the icon Fx is displayed in a semi-transparent manner or the image of the icon Fx is deformed so that it can be visually grasped that the icon Fx does not currently exist.

  Then, among the past information file icons Fc displayed in the file confirmation area 64, the user selects an icon that does not exist in the current information file icon Fb displayed in the file display area 54 with the cursor Cu. When clicked, the playback screen 70 is displayed in the vicinity of the file confirmation area 64, the display frame E is displayed inside the playback screen 70, and an operation is performed as transition information with respect to the inside of the display frame E. Screen G is displayed. By displaying information for identifying the communication terminal C on the information display section Ea of the display frame E, it is possible to specify the communication terminal C or operator who has deleted or moved the information file based on the identification information. It is possible.

[Concept of the Invention]
As described above, in the present invention, in the communication terminal C, when a storage directory is specified and a different date and time is specified, the directory is specified at the specified different date and time based on the operation log stored in the management server A. When the specific information acquisition unit 25 acquires specific information corresponding to the existing file structure and determines that the two types of acquired specific information are different, transition information indicating a situation that has led to a difference is obtained. The transition information acquisition part 26 acquires. This transition information includes character information such as “delete” and “move” and an operation screen G displayed in a moving image format.

  Thereby, in the communication terminal C, the icon, the file name, and the attribute information indicating the current file configuration of the directory (file configuration existing at the new date and time) are displayed on the file display screen 50 displayed on the monitor 8. In addition, the icon that indicates the file structure that exists only at the old date and time, the file name, the attribute information, and the transition information are displayed as character information such as “delete” and “move”, which makes the situation different. Furthermore, when an icon displayed as transition information is selected with the cursor Cu and clicked, transition information indicating a situation in which the information file is different is displayed on the file display screen 50. By doing so, the situation that led to the difference can be grasped more clearly.

  In particular, the icon Fb indicating the current file configuration in the directory and the icon Fc indicating the past file configuration are arranged in parallel as in the file display screen 50 described as [Another Embodiment of File Display Processing]. In addition to displaying the transition information on the file display screen 50, it is possible to easily compare the file structure between the current and the past, and to grasp the situation where the information file is different from the transition information. ing.

  This processing is realized in the communication terminal C connected to the communication network L without using the management server A. That is, the communication terminal C includes the history acquisition unit 22, the history information storage unit 23, the specific information acquisition unit 25, the transition information acquisition unit 26, and the like. That is, the file configuration existing at the new date and time among the specified date and time is displayed on the monitor 8, and among the file configurations existing at the past date and time specified in this directory, the information file that is different from the file configuration at the current date and time, As the information that has led to the difference, it is possible to display the transition information including character information such as “delete” and “move” on the monitor 8.

(B) The information management system is realized by a stand-alone computer that is not connected to the communication network L. In other words, information management is performed so that specific information can be acquired and transition information can be acquired and displayed by specifying an arbitrary directory and specifying a different date and time, using the hard disk provided in the computer itself as storage for information management. Configure the system.

  In order to realize this processing, the computer only needs to include the history acquisition unit 22, the history information storage unit 23, the specific information acquisition unit 25, the transition information acquisition unit 26, and the like. The transition information of the information file deleted by the operation can be displayed on the monitor. In other words, the file structure that exists at a new date and time among the dates and times specified by the computer itself is displayed on the monitor, and the information file that differs from the file structure at the current date and time among the file configurations that existed at the past date and time specified in this directory As for the information that has come to be different, it is possible to display the transition information composed of character information such as “delete” and “move” on the monitor.

(C) As in the case of (b) described above, information management is realized by a program in a stand-alone computer not connected to the communication network L. In other words, information management is performed so that specific information can be acquired and transition information can be acquired and displayed by specifying an arbitrary directory and specifying a different date and time, using the hard disk provided in the computer itself as storage for information management. Provide a program.

  In order to realize this processing, the computer includes a history acquisition unit 22 and a history information storage unit 23, and also includes a specific information acquisition function 25 configured by a program, a transition information acquisition function 26, and an information display function 27. With such a configuration, for example, the transition information of the information file deleted by an erroneous operation can be displayed on its own monitor. In other words, the file structure that exists at a new date and time among the dates and times specified by the computer itself is displayed on the monitor, and the information file that differs from the file structure at the current date and time among the file configurations that existed at the past date and time specified in this directory As for the information that has come to be different, it is possible to display the transition information composed of character information such as “delete” and “move” on the monitor.

(D) The history information storage unit lists and stores the file configuration of each directory in the storage, and is configured to update the file configuration every time the file configuration is changed. The specific information acquisition unit 25 designates the directory. By doing so, the processing form may be set so that the specific information is acquired from the file configuration that is stored in a list.

  In particular, as a storage format when the file configuration of each directory is saved in a list, the date and time information is added every time the file configuration is updated, so that the specific information specifies the date and time of the directory. When acquiring the specific information of the file configuration, it is possible to acquire the file configurations listed and stored in the history information storage unit 23 based on the date / time information.

(E) The communication terminal C or the management server A acquires the access log stored in the storage from the storage, and sets the processing mode so as to acquire the past file configuration based on the access log. In this processing mode, it is possible to easily perform a process of extracting a file structure in a predetermined directory from the acquired access log.
