FIG. 1 is a diagram showing the configuration of an embodiment of a file transfer system according to the present invention. Referring to FIG. 1, in the first embodiment of the present invention, an information distribution server 100 for distributing update files, a portable communication terminal 120 connected to the server 100 via the Internet 110, and a PC not connected to the Internet. (Personal computer) terminal 130. The PC terminal 130 that is not connected to the Internet is a terminal that is used in, for example, a company's mission-critical business system, and is configured so that it cannot be connected to a wide area network such as the Internet from the viewpoint of preventing virus infection and information leakage. However, in the present invention, the PC terminal 130 may be connected to a small-scale network such as a corporate LAN in which access to the outside is restricted. Further, in this embodiment, the file to be transferred is, for example, a pattern file of security countermeasure software. However, the present invention is not limited to this example, and can be applied to all data files necessary for a PC terminal. .

The information distribution server 100 includes a master data storage unit 101 that stores update files to be distributed, a data distribution unit 102 that distributes master data to users, and a registered user data storage unit 103. The registered user data storage unit 103 stores user data registered in advance for the application related to the update file. In this user data, at least the mail address of the portable communication terminal 120 possessed by the user of the PC terminal 130 or its system administrator is registered. In addition, although many users are assumed in the application concerning an update file , when the said user is using the PC terminal (not shown) connected to the internet, the address of the said PC terminal is registered. . As a user registration method, a known method can be used, such as online registration or a method of acquiring a registration card by mail and inputting it to the information distribution server 100. When a new update file used in an application running on the PC terminal 130 is registered in the master data storage unit 101, the information distribution server 100 updates the update file addressed to the mail address registered in the registered user data storage unit 103. Will be sent from time to time.

The mobile communication terminal 120 is a mobile phone with a data communication function possessed by the user of the PC terminal 130 or its system administrator, for example, and can receive data from the information distribution server 100 regardless of location. It is. The portable communication terminal 120 stores a receiving unit 121 for receiving the update file sent, a notification unit 123 for notifying the information of the received update file to a user, the update file received from the information distribution server 100 The data storage unit 124, the data transfer unit 125 that transfers the update file to the PC terminal 130, and the reception information processing unit 122 that controls these elements. The receiving unit 121 performs wireless communication with a wireless base station (not shown) of a mobile phone company connected to the Internet 110 to transmit / receive data. For example, the notification unit 123 includes a display screen and a voice output unit that indicate to the user that a new update file has been received. For these means or functions, a display screen or a speaker employed in a conventional mobile phone can be used.

The data storage unit 124 is an internal storage unit of the portable communication terminal 120, and has a sufficient capacity to store the received update file . As will be described later, the data transfer unit 125 is configured as an output terminal when directly connected to the PC terminal 130 with a cable, as will be described later, and is connected to the PC terminal 130 by infrared communication or Bluetooth (registered trademark). When using the memory card, it is configured as an infrared port or the like, and when using a memory card or the like, it is configured as a drive of the memory card. Receiving information processing section 122 is a program installed in the mobile communication terminal 120 is realized by being read from the memory of the mobile communication terminal 120 to the CPU running. This program may be configured as a partial module of the operating system of the portable communication terminal 120. As will be described later, the operating system of the portable communication terminal 120 is assumed to be different from the operating system of the PC terminal 130 that transfers the update file , so that virus infection from the portable communication terminal 120 to the PC terminal 130 is prevented. To.

The PC terminal 130 that is not connected to the Internet controls the application 131 that is developed from the memory of the PC terminal 130 to the CPU, the storage unit 132 that stores data used by the application 131, and the data update of the storage unit 132. A data update processing unit 133 that receives the update file from the portable communication terminal 120. The application 131 in this embodiment is computer security countermeasure software, and executes a virus check of the PC terminal 130 and detection and prevention of unauthorized access from the outside with reference to a virus pattern file registered in the storage unit 132. The data update processing unit 133 is a program installed in the PC terminal 130 and is realized by being read from the memory of the PC terminal 130 and executed by the CPU. The data update processing unit 133 receives the update file from the portable communication terminal 120 and updates the data in the storage unit 132. The transfer receiving unit 134 is data transmission / reception means corresponding to the data transfer unit 125 of the portable communication terminal 120 described above, that is, configured as a cable terminal, an infrared port, or a memory card drive. As described above, the operating system of the PC terminal 130 is different from the portable communication terminal 120.

The operation of the first embodiment of the data distribution system configured as described above will be described with reference to the flowchart of FIG. In the following description the information distribution server 100, although depicted as operation of the portable communication terminal 120, PC terminals 130, actual data transmission unit 102 of the information delivery server 100 in charge of these operations, the mobile communication terminal 120 The received information processing unit 122 and the data update processing unit 133 of the PC terminal 130.

  When a new computer virus is found, update data to which the virus pattern is added is registered in the information distribution server 100 by the operator. The virus pattern file is a file containing a virus-specific byte pattern, and the application 131 (anti-virus software) recognizes the virus pattern with reference to this pattern file, and the search engine detects the virus. It is said that hundreds of new viruses appear every month, and it is necessary to update (upgrade) the search engine of anti-virus software to search for new complex viruses. Can detect newly appearing viruses by updating the virus pattern file. This information distribution server 100 is operated by a company that develops and sells security countermeasure software to distribute pattern files including the latest virus information to users who have purchased the software via the Internet. Web server.

  The data transmission unit 102 of the present embodiment extracts the update file from the master data storage unit 101, and transmits it to the e-mail address registered in the user data storage unit 103 as an attachment to the e-mail (step 201). This mail delivery may be automatically performed when the data transmission unit 102 detects that new update data has been registered in the master data storage unit 101, or may be executed with the input operation of the operator as a trigger. It may be configured. In addition, the electronic mail may be sent to a plurality of mail addresses registered in the user data storage unit 103 at once, or may be repeatedly sent individually or in a predetermined number of mails.

This update file is distributed to the portable communication terminal 120 via the Internet 110. The portable communication terminal 120 receives the communication file at the receiving unit 121, and the reception information processing unit 122 controls the notification unit 123 to notify the user (step 211), and the received update file is sent to the data storage unit 124. Registration is performed (step 212), and then preparation for transfer to the PC terminal 130 is performed. Here, the reception information processing unit 122 is always activated when the portable communication terminal 120 is powered on, checks the contents of the received e-mail each time, and determines a predetermined character string (transmission of the update file) ( When there is an identification code) or when an attached file is confirmed as an update file from the identifier or the like, a series of processing can be started. By this processing, it is displayed on the display screen of the portable communication terminal 120 that a new update file has been received, and the user is prompted to transfer the received update file to the PC terminal 130. When an update file is received, a beep sound or the like may be generated together with the screen display to attract the user's attention.

The user who sees the message prepares for transfer from the portable communication terminal 120 to the PC terminal 130, and operates the portable communication terminal 120 to execute data transfer (step S212). Specifically, in the case of the embodiment in which the PC terminal 130 is connected with a cable, the user connects the portable communication terminal 120 and the PC terminal 130 with a cable, and the “transfer start” button displayed on the portable communication terminal 120 is displayed on the screen. Click to start data transfer. Further, in the embodiment that performs near field communication such as infrared communication and Bluetooth (registered trademark) with the PC terminal 130, the portable communication terminal 120 is appropriately arranged at a position where it can communicate with the PC terminal 130, and data transfer is started. . In addition, when transferring data via a storage medium such as a memory card, a memory card with sufficient free space is loaded in the portable communication terminal 120, and the update file is stored in the memory card by clicking the button displayed on the screen. Configure to be copied. Here, since the operating systems of the portable communication terminal 120 and the PC terminal 130 are different, the possibility of virus infection due to this data transfer is minimized.

The PC terminal 130 not connected to the Internet receives the update file at the transfer reception unit 134, and the data update processing unit 133 updates the data file in the storage unit 132 searched by the application 131 (step 221). Here, the data update may be configured to overwrite the data file as it is when the latest virus pattern file contains all the past virus pattern data, and the pattern when it has only the latest virus pattern data. The configuration may be such that the latest data is added to the file. Conventionally, many anti-virus software has taken the former form, using a mobile phone often towards the update file that contains only the addition / change portion can be reduced the amount of transfer data, in particular to the mobile communication terminal 120 It is suitable for the case where

  A specific update process will be described with reference to FIG. This figure is a diagram showing a configuration image of an update file. As shown in this figure, items of a processing content 61, a processing index 62, and an updating content 63 are provided for each record. The processing content 61 records the processing method of this record, which includes “add” for “add”, “chg” for “update”, “del” for deletion, and the like. A search key in data to be processed is recorded in the process index 62, and the contents of a pattern file to be newly added / updated are recorded in the update contents 63. The data update processing unit 133 reads this update file for each record, and executes addition / update / deletion processing on the data stored in the storage unit 132. In addition, in the explanation of this processing procedure, addition / update / deletion processing is possible so that it can be applied to other embodiments. However, in the case of virus pattern file update, it is difficult to think of “deletion”. You may comprise so that the processing function only of an update may be provided.

The file update timing may be such that when the transfer request from the portable communication terminal 120 is received, the data update processing unit 133 automatically performs the reception process, and when the reception is completed, the data update is performed. When the request is received, a message to that effect may be displayed on the PC terminal 130 so that the user can receive the update data and confirm the actual update process.

Thus, according to this embodiment, obtain the latest update file in the information distribution server 100 in the mobile communication terminal 120 notifies its availability to the user, transfer from here to the PC terminal 130 is not connected to the Internet Therefore, the virus pattern file of the PC terminal 130 that cannot be connected to a wide area network such as the Internet can be easily updated. In addition, when a new update file is registered in the information distribution server 100, the file is distributed by e-mail, so that the user of the PC terminal 130 not connected to the Internet can detect the presence of the latest pattern, Virus pattern file can be updated in a timely manner. In addition, since it is possible to update virus patterns on the PC terminal 130 without connecting to the Internet or the like, security in terms of virus infection, information leakage, etc., compared to when updating files by connecting to the Internet. Risk is reduced. In addition, the latest update file is obtained through a terminal such as a mobile phone that has an operating system different from that of the PC terminal 130 to be updated. Most computer viruses are stored in the mobile phone operating system. Since it is not infected, the risk of virus infection when transferring files can be greatly reduced. Further, for example, when the PC terminal 130 is a notebook personal computer that an employee carries on a business trip, the update data is received by the mobile phone while moving, and the latest update file is stored in the PC terminal 130 after reaching the purpose. The update file can be obtained efficiently.

Next, a second embodiment will be described. FIG. 4 is a diagram for explaining the operation of the second embodiment of the data distribution system according to the present invention. The configuration of the present embodiment is almost the same as the system shown in FIG. 1, but the file distribution procedure performed between the information distribution server 100 and the portable communication terminal 120 is different, and the data transmission unit 102 of the information distribution server 100 is different. The process is different from the process of the reception information processing unit 122 of the portable communication terminal 120.

When a new virus is found, the operator of the information distribution server 100 registers the update file that contains a novel virus pattern in the master data storage section 101, not distributed to the mobile communication terminal 120 at this time (step 501) . On the other hand, the reception information processing unit 122 of the portable communication terminal 120 periodically connects to the information distribution server 100 and inquires whether a new update file exists (step 511). In this inquiry, the version information of the update file transferred last time is registered in the data storage unit 124 by the portable communication terminal 120, and this version information is included in the notification to the information distribution server 100. The data transmission unit 102 of the information distribution server 100 compares the received version information with the latest update data version information registered in the master data storage unit 101, and if both are different, a new file is created. Is returned (step 502). In another embodiment, the portable communication terminal 120 inquires about the version of the latest update data currently registered in the information distribution server 100, and the portable communication terminal 120 is stored in the own terminal based on the return information. The necessity of updating may be determined by comparing with the version of the previously updated file.

Here, if a new update file exists, the portable communication terminal 120 makes a download request to the information distribution server 100 (step 512), and the information distribution server 100 responds to the latest update from the master data storage unit 101 accordingly. A file is extracted and transmitted to the portable communication terminal 120 (step 503). The subsequent processing is the same as that of the first embodiment shown in FIG. 2, and the same step numbers as those in FIG.

Next, a third embodiment of the present invention will be described with reference to FIGS. In the present embodiment, description will be made assuming that the application 331 of the PC terminal 330 not connected to the Internet is dictionary search software. In the case of dictionary software, when a new buzzword is born, a new word and its meaning are added, when a new meaning occurs in an existing word, the meaning of the existing word is updated, or a temporary buzzword It is effective to update the dictionary data, such as deleting words that are no longer used in, and the version number of the updated dictionary data is managed. Referring to the system of FIG. 5, in addition to the system of FIG. 1, the reception information processing unit 322 of the portable communication terminal 330 further includes an accumulated data management unit 324. The stored data management unit 324 is configured as a program module of the portable communication terminal 320 and manages information on the update file received by the terminal 320.

As shown in the flowchart of FIG. 6, the data transmission unit 302 of the information distribution server 300 extracts the latest update file to be searched for the application from the master data storage unit 301 and transmits it to the portable communication terminal 320 (steps). 401). It is assumed that this distribution process is performed according to any of the procedures in the first and second embodiments described above. The portable communication terminal 320 receives the update file from the information distribution server 300 at the reception unit 321, and the reception information processing unit 322 notifies the user of the update file information using the notification unit 323, and the data storage unit 325. The received update file is registered in (Step 411). At this time, the accumulated data management unit 324 registers the information of the update file in the management table shown in FIG. 7 (step 412).

This confirmation table is stored and managed in the data storage unit 325 and is updated when a new update file is received or when each file is transferred to the PC terminal 330. As shown in FIG. 7, a record is created for each update file in the confirmation table, and each record has at least items of file name 52, version information 53, update terminal identification information 54, and update flag 55. In the file name 52 and the version information 53, the file name and version information of the update file are registered, and in the update terminal identification information 54, the portable communication terminal 320 updates the latest dictionary data of the dictionary search software. And the flag indicating whether or not the dictionary data has been updated is registered in the update flag 55.

  In the embodiment shown in FIG. 7, in the record of REC01, the dictionary data with the file name “jdata60” in the sixth edition (version 060) was registered in the data storage unit 325 in the sixth edition (version 060). Since the update flag to the PC terminal (PC terminal 330) having the identifier “0” is “0”, data transfer is not yet performed. On the other hand, in the record of REC02, similarly, the fifth version of the dictionary data has the update flag to the PC terminal 330 with the identifier “abcd001” being “1”, and the dictionary data is being updated. I understand. The information of the update data obtained this time is added to this as REC003 (seventh edition data).

  Next, the accumulated data management unit 324 confirms the information of the update file of the dictionary search software including the data accumulated in the data accumulation unit 325 in the past, and determines the update file that needs to be added / updated this time ( Step 412). In this process, the update data whose update flag is “0” (unupdated) is specified with reference to the data stored in the data storage unit 325, and the update data specified here is read from the data storage unit 325. Extract and transfer to the PC terminal 330. In the embodiment of FIG. 7, REC03 (seventh version dictionary data) and REC02 (sixth version dictionary data) are extracted and transferred to the PC terminal 330 with the identifier abcd001. Since this transfer and subsequent processing are the same as those in the first and second embodiments described above, the subsequent description is omitted.

  According to the present embodiment, for example, as described above, when the PC terminal 330 is a notebook personal computer carried on a business trip and two or more update files are released in a relatively short period of time, the first The second and subsequent files are received and stored even when the update is not performed by the file, and when the corresponding time is reached, the unupdated file is extracted and transferred to the PC terminal, and the dictionary data Can be updated. This embodiment is particularly effective for an application in which an update file is released without a relatively long interval, for example, educational software teaching material data in which a new curriculum is transmitted daily or weekly.

Although several embodiments of the present invention have been described in detail, the present invention is not limited to the above-described embodiments, and various other embodiments can be considered. In particular, applications on PC terminals and their reference files (data files to be updated) are, for example, dictionary data files in dictionary search software, law / case data in law / case search software, map data in map search software, various education If it is search target data or content data that is used in an application with functions such as search and attendance in the area, such as educational content data that has different contents every time in the software, the content is added / updated as necessary. It can be applied to various examples. Further, the data transfer procedure between the information distribution server and the portable communication terminal is not limited to the above embodiment. For example, when a new update file is registered in the information distribution server, an email to that effect is distributed to each user's portable communication terminal without attaching the file, and the information is distributed from the portable communication terminal that receives this It may be configured to access the server and download the update file.

  The present invention restricts connection to a wide area network such as the Internet due to security problems, and an update file that needs to be obtained from the Internet on a PC terminal connected to a network where access is managed locally or within a company. It is made available in a safe and timely manner, and can be used in the information communication industry and other industries using computers.
