Description

  The present invention relates to a transfer device, a transfer method, and a transfer program.

  Conventionally, a mail system is often used for sending and receiving electronic files such as electronic documents, images, and moving images over the Internet. In a mail system, a user can easily send and receive an electronic file by attaching the electronic file to an electronic mail.

  However, the mail system generally has a limitation on the size of a file that can be transmitted and received, and thus has a problem that it cannot cope with an increase in the size of an electronic file as digital technology develops. For this reason, in recent years, there has been an increasing demand for services for sending and receiving electronic files using a file transfer server arranged on the Internet. As a system that meets this need, a base system capable of transmitting and receiving a large-capacity electronic file is known, as in the technique described in Non-Patent Document 1 or Non-Patent Document 2.

  The above-mentioned infrastructure system also responds to social demands for information leakage, makes it possible to send and receive large-capacity electronic files, and retains history information related to transmission / reception processing. In other words, when this infrastructure system is used, a user can send and receive a large-capacity electronic file with security secured. In addition, for example, the administrator obtains history information held in the base system, thereby monitoring whether the confidential information is transmitted to outsiders and whether the receiver acquires the confidential information. can do.

  However, the technique of monitoring by acquiring history information has a problem that the number of monitoring steps by an administrator increases. Specifically, every time the administrator performs a monitoring operation, the administrator needs to access the base system and acquire history information. For example, when monitoring whether the electronic file transmitted from the user A to the user B is received by the user B from the infrastructure system, the administrator periodically acquires history information from the infrastructure system and uses it. It is confirmed whether the user B has acquired the electronic file from the base system. Such a thing causes the problem of increasing the monitoring man-hour of the administrator.

  The present invention has been made in view of the above, and an object thereof is to provide a transfer device, a transfer method, and a transfer program that can reduce the monitoring man-hours by an administrator.

  Hereinafter, embodiments of a transfer device, a transfer method, and a transfer program according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by this Example.

  First, the transfer apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating a configuration example of a transfer apparatus according to the first embodiment. As illustrated in FIG. 1, the transfer device 10 according to the first embodiment includes a data storage unit 11, a history information storage unit 12, a storage unit 13, a history information registration unit 14, a monitoring unit 15, and history information transmission. Part 16.

  The data storage unit 11 stores data received by the transfer device 10 from an external terminal or the like. The history information storage unit 12 stores history information regarding data transmission / reception for each data stored in the data storage unit 11.

  When receiving a data transmission request from an external terminal or the like, the storage unit 13 stores data included in the transmission request in the data storage unit 11. At this time, the storage unit 13 according to the first embodiment adds the destination information of the manager corresponding to the data sender to the data destination. Here, the “manager corresponding to the data sender” refers to, for example, an upper manager or a security manager who monitors the sender.

  For example, it is assumed that the upper Y of the user X monitors data transmission / reception performed by the user X. In such a case, when the user X receives a transmission request for data that is a transmission source of the user X, the storage unit 13 adds the upper long Y destination to the transmission destination of the data and then stores the data in the data storage unit 11. To store. Thereby, since the upper manager Y can receive the data transmitted by the user X, the data transmission / reception by the user X can be monitored.

  When the storage unit 13 stores data in the data storage unit 11, the history information registration unit 14 registers history information regarding transmission / reception of such data in the history information storage unit 12. For example, the history information registration unit 14 registers data transmission source information, transmission destination information, transmission date and time, and the like in the history information storage unit 12.

  The monitoring unit 15 monitors whether the storage period of the data stored in the data storage unit 11 exceeds a predetermined threshold value. For example, the monitoring unit 15 monitors whether or not the time from the data transmission date and time to the current date and time exceeds a predetermined storage period for each data stored in the data storage unit 11.

  The history information transmitting unit 16 includes, in the history information corresponding to the data determined by the monitoring unit 15 that the storage period has exceeded, the history of the destination information including the administrator's destination added by the storage unit 13 Information is extracted from the history information storage unit 12. Then, the history information transmission unit 16 transmits the history information extracted from the history information storage unit 12 for each administrator destination.

  As described above, when the transfer device 10 according to the first embodiment receives a data transmission request, the transfer device 10 retains data in which a manager who monitors a data sender is added as a destination for a predetermined storage period. The transfer device 10 holds history information related to data transmission / reception, and transmits the data history information to the administrator after the data storage period has expired.

  In general, data whose storage period has been exceeded is not transmitted or received between users thereafter. That is, the history information of data whose storage period has exceeded will not change thereafter. Since the transfer device 10 according to the first embodiment transmits history information of such data to the administrator after the data storage period has expired, it is possible to provide the administrator with history information that is unlikely to change thereafter. it can. In other words, since the administrator can automatically receive history information that is not likely to fluctuate from the transfer device 10, the administrator can perform monitoring work without performing the work of acquiring history information from the transfer device 10 many times. it can. For example, when the administrator monitors whether or not the user B has received the electronic file transmitted from the user A to the user B, the administrator need only confirm the history information transmitted from the transfer device 10. Thereafter, it is not necessary to acquire history information from the transfer device 10. From the above, the transfer apparatus 10 according to the first embodiment can reduce the monitoring man-hours for the administrator.

  Next, in the second embodiment, a case where the transfer device disclosed in the present application is applied to a file transfer system will be described as an example. In the following, the configuration of the file transfer system, the configuration of the transfer device, and the processing procedure by the transfer device will be described in order.

[Configuration of file transfer system]
First, a file transfer system to which the transfer apparatus according to the second embodiment is applied will be described with reference to FIG. FIG. 2 is a diagram illustrating a configuration example of a file transfer system to which the transfer apparatus according to the second embodiment is applied. As illustrated in FIG. 2, the file transfer system 1 according to the second embodiment includes a transfer device 100 and terminals 210 and 220.

  In the example shown in FIG. 2, it is assumed that the transfer device 100 and the terminal 210 are connected by a secure line. Similarly, it is assumed that the transfer device 100 and the terminal 220 are connected by a secure line. Hereinafter, file transfer processing by the file transfer system 1 shown in FIG. 2 will be described. Hereinafter, a case where the terminal 210 transmits an electronic file or the like to the terminal 220 will be described as an example.

  In the second embodiment, the terminals 210 and 220 send and receive electronic files such as electronic documents, images, and moving pictures together with the body of the electronic mail, send and receive only electronic mail, and send and receive only electronic files. Hereinafter, an electronic mail, an electronic file, or the like transmitted / received by the terminal 210 or the like may be referred to as “container”. For example, a single container may include a plurality of electronic files, or may include only electronic mail.

  When transmitting a container to the terminal 220, the terminal 210 transmits a transmission request including the transmission source information, the transmission destination information, and the container to the transfer apparatus 100. Here, the transmission source information is information for identifying a sender who transmits a container. The transmission destination information is information for identifying a recipient who receives the container. For example, the transmission source information and the transmission destination information are user accounts of the sender and the receiver. The user account is assigned to a user who uses the file transfer system 1, for example.

  When the transfer apparatus 100 receives a transmission request from the terminal 210, the transfer apparatus 100 adds a destination of an administrator who monitors the sender of the container to the transmission destination information of the container included in the transmission request. The transfer apparatus 100 holds the container and holds the transmission source information, the transmission destination information, and the transmission date / time of the container as history information. Note that the transfer device 100 according to the second embodiment holds the container only for a predetermined storage period. For example, when a predetermined storage period has elapsed after receiving a container from the terminal 210, the transfer apparatus 100 discards the container or moves it to a data backup area or the like.

  When receiving a container from the terminal 210, the terminal 220 accesses the transfer apparatus 100 and acquires the container from the transfer apparatus 100. Specifically, the terminal 220 transmits an acquisition request including acquisition source information to the transfer apparatus 100. Here, the acquisition source information is information for identifying a recipient who receives the container, for example, a user account of the recipient.

  When the transfer apparatus 100 receives an acquisition request from the terminal 220, the transfer apparatus 100 determines whether or not the acquisition source information of the acquisition request is included in the transmission destination information of the acquisition request target container. Then, the transfer device 100 transmits the container to the terminal 220 when the acquisition source information is included in the transmission destination information.

  As described above, in the file transfer system 1 in which containers are transmitted and received between terminals, the transfer apparatus 100 according to the second embodiment periodically monitors the reception status of containers, and the period during which no containers are received is a predetermined threshold. If it is longer, a warning that the container has not been received is notified to the administrator added to the destination of the container.

  Furthermore, when there is a container whose storage period has exceeded, the transfer apparatus 100 according to the second embodiment transmits the history information of the container to the administrator added to the transmission destination of the container. Hereinafter, the warning notification process and the history information transmission process performed by the transfer apparatus 100 will be described in detail.

[Configuration of transfer device]
Next, a transfer apparatus according to the second embodiment will be described with reference to FIG. FIG. 3 is a block diagram illustrating a configuration example of the transfer apparatus according to the second embodiment. As illustrated in FIG. 3, the transfer device 100 according to the second embodiment includes a container storage unit 111, a user information storage unit 112, a history information storage unit 113, a monitoring information storage unit 114, a transmission / reception control unit 121, A history information management unit 122, a history information transmission unit 123, and a non-reception monitoring unit 124 are included.

  The container storage unit 111 stores a container transmitted from the terminal 210 or the like. Specifically, the container storage unit 111 stores containers by a transmission / reception control unit 121 described later. The container storage unit 111 corresponds to the data storage unit 11 shown in FIG.

  The user information storage unit 112 stores various types of information related to users who use the file transfer system 1. FIG. 4 shows an example of the user information storage unit 112. As shown in FIG. 4, the user information storage unit 112 includes items such as “user account”, “forced broadcast flag”, and “forced broadcast destination account”.

  “User account” is information for identifying a user who uses the file transfer system 1. This “user account” is used, for example, when a user logs in to the transfer apparatus 100.

  The “forced broadcast flag” is information indicating whether or not a user account to be forcibly added exists at the transmission destination of the container whose transmission source is the corresponding user account. In the example shown in FIG. 4, when the “forced broadcast flag” is “ON”, it indicates that there is a destination to be forcibly added, and when the “forced broadcast flag” is “OFF”. Indicates that there is no destination to be forcibly added.

  The “forced broadcast destination account” indicates a user account that is forcibly added to a transmission destination of a container whose corresponding user account is a transmission source. In the “forced broadcast destination account”, for example, a user account such as an administrator who monitors transmission / reception of a container by a corresponding user account is stored.

  For example, the user information storage unit 112 illustrated in FIG. 4 indicates that the forced broadcast destination account “audit_001” is added to the transmission destination of the container whose user account “user_001” is the transmission source. Further, for example, the user information storage unit 112 illustrated in FIG. 4 indicates that the forced broadcast destination account is not added to the transmission destination of the container whose transmission source is the user account “user_002”.

  The history information storage unit 113 stores history information related to container transmission / reception. FIG. 5 shows an example of the history information storage unit 113. As illustrated in FIG. 5, the history information storage unit 113 includes “transmission ID”, “sender account”, “transmission date / time”, “attached file name”, “recipient account”, “reception history”, “history update”. Items such as “date and time”, “end processing status”, and “history transmission status” are included.

  “Transmission ID” indicates identification information for identifying a transmission request received from the terminal 210 or the like. In other words, the “transmission ID” is also identification information for identifying the container. That is, each time the transfer apparatus 100 receives a transmission request from the terminal 210 or the like, the history information storage unit 113 adds a record corresponding to the newly issued transmission ID.

  “Sender account” indicates the user account of the sender who sent the container. “Transmission date and time” indicates the date and time when the container is transmitted, for example, the date and time when the container is transmitted from the terminal 210 or the like. FIG. 5 shows an example in which the year, month, and date are stored in “transmission date and time”. “Attached file name” indicates the name of the electronic file included in the container. The “recipient account” indicates a user account of a container transmission destination.

  “Reception history” indicates whether or not the container is received by the user indicated by the recipient account. In the example shown in FIG. 5, when “Reception history” is “Received”, it indicates that the container is received by the user indicated by the corresponding recipient account, and “Reception history” is “Not received”. ", The container is not received by the user indicated by the corresponding recipient account.

  “History update date / time” indicates the date / time when the corresponding record was updated. “End processing status” indicates whether the container has exceeded a predetermined storage period. In the example shown in FIG. 5, when the “end processing status” is “ON”, it indicates that the container transmitted at the time of the transmission request specified by the corresponding transmission ID has exceeded the storage period, When the “end processing status” is “OFF”, it indicates that the storage period has not been exceeded.

  “History transmission status” indicates whether history information has been transmitted to the forced broadcaster. In the example illustrated in FIG. 5, when “history transmission status” is “ON”, it indicates that history information has been transmitted to the forced broadcaster, and “history transmission status” is “OFF”. Indicates that the history information is not transmitted to the forced broadcaster.

  For example, in the history information storage unit 113 illustrated in FIG. 5, the transmission source of the container specified by the transmission ID “0001” is the sender account “user_001”, and the transmission destinations are the receiver accounts “user_aaa” and “user_bbb”. And “audit_001”. Further, in the history information storage unit 113 illustrated in FIG. 5, the container with the transmission ID “0001” is transmitted at “13:45 on February 15, 2010”, and the attached file names “AAA” and “BBB” are used. It shows that two electronic files are included. In the history information storage unit 113 illustrated in FIG. 5, the container having the transmission ID “0001” is received by the receiver accounts “user_aaa” and “audit_001”, but is not received by the receiver account “user_bbb”. It shows no. The history information storage unit 113 corresponds to the history information storage unit 12 illustrated in FIG.

  The monitoring information storage unit 114 stores setting information used during monitoring processing by a history information transmission unit 123 and a non-reception monitoring unit 124 described later. FIG. 6 shows an example of the monitoring information storage unit 114. As shown in FIG. 6, the monitoring information storage unit 114 includes “forced broadcast destination account”, “history transmission flag”, “history transmission destination”, “unreceived warning flag”, “unreceived warning period”, “unreceived warning period”, It has an item such as “reception warning transmission destination”.

  The “forced broadcast destination account” corresponds to the forced broadcast destination account shown in FIG. The “history transmission flag” indicates whether or not the corresponding forced broadcast destination account is a user account that receives history information. In the example shown in FIG. 6, when the “history transmission flag” is “ON”, it indicates that the corresponding forced broadcast destination account receives history information, and the “history transmission flag” is “OFF”. If there is, it indicates that the corresponding forced broadcast destination account does not receive history information. “History transmission destination” indicates a transmission destination of history information when the corresponding forced broadcast destination account is a user account that receives history information.

  The “unreceived warning flag” indicates whether or not the corresponding forced broadcast destination account is a user account that receives a warning notification when the container is not received. In the example shown in FIG. 6, when the “unreceived warning flag” is “ON”, it indicates that the corresponding forced broadcast destination account receives a warning notification, and the “unreceived warning flag” is “OFF”. "Indicates that the corresponding compulsory broadcast account does not receive a warning notification.

  “Non-reception warning period” indicates a threshold of a period during which the container is not yet received. Specifically, the non-reception monitoring unit 124 described later notifies a warning when the period during which the container is not received is longer than the period stored in the “non-reception warning period”. “Non-reception warning transmission destination” indicates a warning notification destination.

  For example, in the monitoring information storage unit 114 illustrated in FIG. 6, the forced broadcast destination account “audit_001” receives history information addressed to “audit_001”, and receives a warning notification when “container is not received” addressed to “audit_001”. Indicates a user account. Further, for example, the monitoring information storage unit 114 illustrated in FIG. 6 indicates that the forced broadcast destination account “audit_002” is a user account that does not receive history information and receives a warning notification addressed to “audit_002”. ing. Further, for example, the monitoring information storage unit 114 illustrated in FIG. 6 indicates that the forced broadcast destination account “audit_003” is a user account that receives history information to “audit_999” and does not receive a warning notification. Yes.

  Note that, as in the example of the forced broadcast destination account “audit_003”, the user account “audit_003” that receives the container and the user account “audit_999” that receives the history information may be different user accounts. Thereby, for example, even when the terminal corresponding to the user account that receives the container is out of order, the user account corresponding to the terminal that is not out of order is set to “history transmission destination” or “non-reception warning transmission destination”. By setting to, the administrator can receive history information and warning notifications. Further, for example, even when the administrator cannot use such a terminal due to a long-term business trip or the like, by setting the user account corresponding to the terminal on the business trip destination to “history transmission destination” or “unreceived warning transmission destination” The administrator can receive history information and warning notifications.

  In addition, a plurality of user accounts may be set in the “history transmission destination” and “non-reception warning transmission destination”. For example, in the example illustrated in FIG. 6, user accounts such as “audit_001” and “audit_100” may be set in “history transmission destination” corresponding to the forced broadcast destination account “audit_001”. In addition, for example, user accounts such as “audit_001” and “audit_100” may be set in “unreceived warning transmission destination” corresponding to the forced broadcast destination account “audit_001”. Thereby, the administrator can receive the history information and the warning notification by a plurality of user accounts.

  The transmission / reception control unit 121 controls container transmission / reception processing when a transmission request or an acquisition request is received from the terminal 210 or the like. Specifically, when receiving a container transmission request from the terminal 210 or the like, the transmission / reception control unit 121 acquires, from the user information storage unit 112, a record in which the container transmission source matches the user account. When the forced broadcast flag acquired from the user information storage unit 112 is “ON”, the transmission / reception control unit 121 sets the forced broadcast destination account acquired from the user information storage unit 112 as the container transmission destination. After the addition, the container is stored in the container storage unit 111. On the other hand, when the forced broadcast flag acquired from the user information storage unit 112 is “OFF”, the transmission / reception control unit 121 stores the container in the container without adding the forced broadcast destination account to the container transmission destination. Stored in the unit 111.

  Further, when receiving a container acquisition request from the terminal 210 or the like, the transmission / reception control unit 121 receives, from the history information storage unit 113, a receiver account corresponding to the transmission ID for identifying the acquisition request target container, and the termination processing status. To get. The transmission / reception control unit 121 rejects the container acquisition request when the receiver account acquired from the history information storage unit 113 does not include the user account of the container receiver who transmitted the acquisition request. On the other hand, when the receiver account acquired from the history information storage unit 113 includes the user account of the container receiver who transmitted the acquisition request, the transmission / reception control unit 121 indicates that the end processing status is “OFF” or “ON”. It is determined which one is. When the end process status is “OFF”, the transmission / reception control unit 121 indicates that the acquisition request target container has not exceeded the predetermined storage period, and transmits the container to the terminal 210 or the like. . At this time, the transmission / reception control unit 121 also transmits a transmission ID for identifying the container together with the container. On the other hand, when the end process status is “ON”, the transmission / reception control unit 121 indicates that the acquisition request target container has exceeded the predetermined storage period, and therefore rejects the container acquisition request.

  The transmission / reception control unit 121 notifies the history information management unit 122 of the results of various processes after the container storage process, transmission process, and the like are completed. As a result, various information stored in the history information storage unit 113 is updated by the history information management unit 122.

  Here, various processes by the transmission / reception control unit 121 will be described with examples. In the following, various information stored in the user information storage unit 112 is in the state illustrated in FIG. 4, and various information stored in the history information storage unit 113 is in the state illustrated in FIG. To do.

  For example, it is assumed that the transmission / reception control unit 121 receives a transmission request having the transmission source “user_001” from the terminal 210 or the like. In such a case, the transmission / reception control unit 121 acquires the forced flag “ON” corresponding to the user account “user_001” and the forced broadcast destination account “audit_001” from the user information storage unit 112. Since the forced flag is “ON”, the transmission / reception control unit 121 adds the forced broadcast destination account “audit_001” to the destination of the container included in the transmission request, and the container storage unit 111 adds the container after the destination is added. To store.

  For example, it is assumed that the transmission / reception control unit 121 receives a transmission request having the transmission source “user — 002” from the terminal 210 or the like. In such a case, the transmission / reception control unit 121 acquires the forced flag “OFF” corresponding to the user account “user — 002” and the forced broadcast destination account “−” from the user information storage unit 112. Then, since the forced flag is “OFF”, the transmission / reception control unit 121 stores the container in the container storage unit 111 without adding the forced broadcast destination account to the transmission destination of the container included in the transmission request.

  For example, it is assumed that the transmission / reception control unit 121 receives a container acquisition request from the terminal 210 or the like. Here, it is assumed that the acquisition request includes information indicating that the acquisition target container is the transmission ID “0001” and the user account “user_aaa” of the recipient. In such a case, the transmission / reception control unit 121 acquires a record corresponding to the transmission ID “0001” from the history information storage unit 113. Then, since the “user_aaa” is included in the receiver account acquired from the history information storage unit 113, the transmission / reception control unit 121 determines whether the end processing status is “OFF” or “ON”. Here, since the end process status is “ON”, the transmission / reception control unit 121 rejects the container acquisition request to the terminal 210 or the like.

  For example, the transmission / reception control unit 121 receives an acquisition request including information indicating that the acquisition target container is the transmission ID “0002” and the user account “user_bbb” of the recipient from the terminal 210 or the like. And In such a case, the transmission / reception control unit 121 acquires a record corresponding to the transmission ID “0002” from the history information storage unit 113. The transmission / reception control unit 121 includes “user_bbb” in the receiver account acquired from the history information storage unit 113 and the end processing status is “OFF”. The container specified by “0002” is transmitted.

  The history information management unit 122 manages various information stored in the history information storage unit 113. Specifically, when the container is stored in the container storage unit 111 by the transmission / reception control unit 121, the history information management unit 122 pays out a transmission ID for identifying the container. Then, the history information management unit 122 obtains a transmission ID, a sender account that is a container transmission source, a container transmission date and time, an electronic file name included in the container, and a receiver account that is a container transmission destination. Register in the history information storage unit 113. At this time, the history information management unit 122 registers “not received” in the reception history of the history information storage unit 113, registers the current system date and time as the history update date and time, and registers “OFF” as the end processing status. Then, “OFF” is registered in the history transmission status.

  Further, the history information management unit 122 updates the reception history and the history update date / time stored in the history information storage unit 113 when the transmission / reception control unit 121 transmits a container to the terminal 210 or the like.

  Further, the history information management unit 122 periodically monitors the history information storage unit 113 and performs a termination process for invalidating a container whose storage period has been exceeded. Specifically, the history information management unit 122 acquires a record whose end processing status is “OFF” from the history information storage unit 113. Then, the history information management unit 122 calculates a storage period that is a difference between the transmission date / time of the record acquired from the history information storage unit 113 and the current system date / time. Then, the history information management unit 122 updates the end processing status from “OFF” to “ON” when the calculated storage period is longer than a predetermined threshold.

  The history information transmission unit 123 periodically refers to the history information storage unit 113, and when there is a container whose storage period has exceeded, transmits the history information of the container to the administrator. Specifically, the history information transmission unit 123 acquires the forced broadcast destination account and the history transmission destination whose history transmission flag is “ON” from the monitoring information storage unit 114. Then, the history information transmission unit 123 performs the following processing for each forced broadcast destination account acquired from the monitoring information storage unit 114. First, the history information transmission unit 123 acquires all records in which the forced broadcast destination account is included in the recipient account from the history information storage unit 113. Then, the history information transmission unit 123 extracts a record in which the end process status is “ON” and the history transmission status is “OFF” from the acquired records. Then, the history information transmission unit 123 transmits the history information that is the extracted record to the history transmission destination acquired as described above. That is, the history information transmission unit 123 transmits history information collectively for each history transmission destination. Then, after the history information is transmitted, the history information transmission unit 123 updates the history transmission status of the history information transmission unit 123 corresponding to the record transmitted to the history transmission destination from “OFF” to “ON”.

  Here, the history information transmission processing by the history information transmission unit 123 will be described with an example. In the following, the various information stored in the history information storage unit 113 is in the state illustrated in FIG. 5, and the various information stored in the monitoring information storage unit 114 is in the state illustrated in FIG. To do.

  The history information transmission unit 123 receives from the monitoring information storage unit 114 a combination of the forced broadcast destination account “audit_001” with the history transmission flag “ON” and the history transmission destination “audit_001”, and the forced broadcast destination account “ The combination of “audit_003” and the history transmission destination “audit_999” is acquired. Then, the history information transmission unit 123 acquires a record in which “audit — 001” is included in the recipient account from the history information storage unit 113. Here, the history information transmission unit 123 receives, from the history information storage unit 113, a record with a transmission ID “0001”, a record with a transmission ID “0004”, and a record with a transmission ID “0005”. get.

  Here, the record whose transmission ID is “0001” has an end processing status of “ON” and a history transmission status of “OFF”. Further, the record whose transmission ID is “0004” has an end process status of “ON” and a history transmission status of “OFF”. Further, the record whose transmission ID is “0005” has the end process status “OFF” and the history transmission status “OFF”. Therefore, the history information transmission unit 123 transmits the record with the transmission ID “0001” and the record with the transmission ID “0004” to the history transmission destination “audit_001” as the history information. Then, the history information transmission unit 123 updates the history transmission status corresponding to the transmission ID “0001” in the history information storage unit 113 from “OFF” to “ON”, and the history transmission status corresponding to the transmission ID “0004”. Is updated from “OFF” to “ON”.

  Subsequently, the history information transmission unit 123 acquires a record including “audid_003” in the recipient account from the history information storage unit 113. Here, the history information transmission unit 123 acquires a record whose transmission ID is “0003” from the history information storage unit 113. The history information transmission unit 123 does not transmit the history information to the history transmission destination “audid_999” because the history transmission status of the record acquired from the history information storage unit 113 is “ON”.

  In the above example, the history information transmission unit 123 transmits the history information collectively for each history transmission destination. However, the history information transmission unit 123 may transmit history information to the history transmission destination for each transmission ID.

  The non-reception monitoring unit 124 periodically refers to the history information storage unit 113 and notifies the administrator of a warning when the period during which the container is not received is longer than a predetermined threshold. Specifically, the non-reception monitoring unit 124 acquires, from the monitoring information storage unit 114, a forced broadcast destination account whose non-reception warning flag is “ON”, a non-reception warning period, and a non-reception warning transmission destination. Then, the non-reception monitoring unit 124 acquires, from the history information storage unit 113, a record in which the forced broadcast destination account acquired as described above is included in the receiver account. Then, the unreception monitoring unit 124 extracts a record in which the end processing status included in the acquired record is “OFF” and the reception history includes “unreceived”. Then, the non-reception monitoring unit 124 calculates a non-reception period that is the difference between the history update date and time and the current system date and time, and compares the calculated non-reception period with the non-reception warning period acquired above. Then, if the non-reception period is longer than the non-reception warning period, the non-reception monitoring unit 124 notifies the non-reception warning transmission destination of a warning.

  Here, the warning notification process by the non-reception monitoring unit 124 will be described with an example. In the following, the various information stored in the history information storage unit 113 is in the state illustrated in FIG. 5, and the various information stored in the monitoring information storage unit 114 is in the state illustrated in FIG. To do.

  The non-reception monitoring unit 124, from the monitoring information storage unit 114, the forced broadcast destination account “audit_001”, the non-reception warning period “24 hours”, and the non-reception warning transmission destination “audit_001” whose non-reception warning flag is “ON”. And a combination of the forced broadcast destination account “audit_002”, the non-reception warning period “72 hours”, and the non-reception warning transmission destination “audit_002”.

  Then, the non-reception monitoring unit 124 acquires a record in which “audit_001” is included in the recipient account from the history information storage unit 113. Here, the non-reception monitoring unit 124 stores, from the history information storage unit 113, a record with a transmission ID “0001”, a record with a transmission ID “0004”, and a record with a transmission ID “0005”. get. Here, the record whose transmission ID is “0005” has the end process status “OFF” and the reception history corresponding to the recipient account “audit_001” is “not received”.

  Accordingly, the non-reception monitoring unit 124 is the difference between the history update date “February 19, 2010 11:00” corresponding to the recipient account “audit_001” of the record with the transmission ID “0005” and the current system date. Calculate the non-reception period. Then, when the calculated non-reception period is longer than the non-reception warning period “24 hours”, the non-reception monitoring unit 124 notifies the non-reception warning transmission destination “audit_001” of a warning.

  The non-reception monitoring unit 124 determines whether to notify the warning including not only the history update date / time corresponding to the recipient account “audit_001” but also the history update date / time corresponding to another recipient account. Also good. For example, in the above example, the record with the transmission ID “0005” stores three history update dates and times. At this time, the non-reception monitoring unit 124 uses the history update date / time of the three history update dates / times whose reception history is “not received” and the minimum value (the most recent date / time). May be calculated. That is, in this example, the non-reception monitoring unit 124 calculates a non-reception period that is a difference between “February 19, 2010, 10:00” and the current system date and time. Then, when the calculated non-reception period is longer than the non-reception warning period “24 hours”, the non-reception monitoring unit 124 notifies the non-reception warning transmission destination “audit_001” of a warning.

  In addition, the non-reception monitoring unit 124 has a history in which the reception history is “not received” and the maximum value (the most recent date and time) when a plurality of history update dates and times are stored in one record. The non-reception period may be calculated using the update date and time. Further, the non-reception monitoring unit 124 may calculate the non-reception period using the average value of the history update dates and times when the reception history is “not received”.

  Subsequently, the non-reception monitoring unit 124 acquires a record in which “audit — 002” is included in the recipient account from the history information storage unit 113. Here, the non-reception monitoring unit 124 acquires a record whose transmission ID is “0003” from the history information storage unit 113. Then, since the end processing status of the record is “ON”, the non-reception monitoring unit 124 does not notify the non-reception warning transmission destination “audit_002”.

  The history information transmitting unit 123 and the non-reception monitoring unit 124 transmit history information to the administrator or notify a warning using a communication network other than the communication network provided by the file transfer system 1. May be. For example, the history information transmission unit 123 may transmit the history information to the administrator using a communication network such as e-mail or fax. Thereby, for example, even when the communication network connecting the transfer device 100 and the terminal 210 is out of order, the history information transmission unit 123 can transmit the history information to the administrator and has not received it. The monitoring unit 124 can notify the administrator of a warning.

[Effect of Example 2]
As described above, since the transfer device 100 according to the second embodiment transmits history information regarding a container that has exceeded a predetermined storage period to the administrator, the number of monitoring steps for the administrator can be reduced. Specifically, since the transfer device 100 transmits history information that is unlikely to fluctuate to the administrator, it is possible to reduce the work of the administrator who acquires the history information many times. In addition, the transfer apparatus 100 according to the second embodiment sorts history information for each administrator added to the container transmission destination, and transmits the sorted history information to the administrator. Only the administrator can send history information about such containers.

  In addition, since the transfer device 100 according to the second embodiment transmits history information including the reception history to the administrator, the administrator can grasp the reception status of the container. For example, the administrator who has received the history information from the transfer apparatus 100 can monitor whether or not the user B has received an electronic file transmitted from the user A to the user B.

  Further, when receiving an acquisition request, the transfer apparatus 100 according to the second embodiment transmits a container and a transmission ID for identifying the container to the transmission source of the acquisition request. In addition, the transfer device 100 transmits history information including a transmission ID to the administrator. In other words, the administrator acquires a container and a transmission ID for identifying the container from the transfer apparatus 100, and receives history information including the transmission ID from the transfer apparatus 100. As a result, the administrator can associate the container ID indicating the acquired container with the transmission ID included in the history information received from the transfer apparatus 100, so that the monitoring operation can be easily performed. For this reason, the transfer device 100 according to the second embodiment can reduce the number of monitoring steps for the administrator.

  The terminal 210 or the like that receives the container and history information may have a function of automatically associating the container and the history information with the transmission ID as a key. For example, the terminal 210 or the like may automatically generate a directory (folder) for each transmission ID, and store the container and history information in a directory corresponding to the transmission ID.

  Further, the transfer apparatus 100 according to the second embodiment periodically monitors the reception status of the container. If the period during which the container is not received is longer than a predetermined threshold, the container is received by the administrator. Notify that there is no warning. Thereby, the transfer apparatus 100 according to the second embodiment can notify the administrator of a container reception failure or a system failure. For example, an administrator who has received a warning from the transfer apparatus 100 can notify a user who is a container transmission destination to receive a container, and therefore can prevent container reception omission. . For example, when the container receiving system is out of order, the administrator can detect such a failure by receiving a warning from the transfer apparatus 100.

  In the above-described embodiment, each component of each illustrated apparatus is functionally conceptual and does not necessarily need to be physically configured as illustrated.
