  On the other hand, as shown in FIG. 5A, the search screen displayed for the active user running the personal server software is not limited to the configuration of the search screen for inactive users, A desktop search button 55 for instructing execution is added.

  The service providing server 20 determines whether or not the accessing user terminal device 10 is active based on detection / management of the active user management means 21 and displays the desktop search button 55 on the screen. Determine whether or not.

  FIG. 6 is a flowchart showing a flow of desktop search processing by the desktop search module 15a.

  First, when the user accesses the service providing server 20 from the user terminal device 10, in response to the access, the service providing server 20 transmits web page information including the search expression input box 53 (S110). At this time, the service providing server 20 detects whether or not the user terminal device 10 is active, and if it is active, sends the web page information including the desktop search button 55 to the user terminal device 10.

  Here, when the user terminal device 10 is not active, the desktop search button 55 is not displayed as shown in FIG. 5B, and at this time, the same processing as in the conventional case continues.

  On the other hand, when the user terminal device 10 is active, a web page as shown in FIG. 5A is displayed on the user terminal device 10 based on the received web page information. Here, after inputting a search expression such as a keyword in the input box 53, the user clicks the desktop search button 55 to instruct the service providing server 20 to execute desktop search (S111).

  Upon receiving the desktop search execution instruction, the service providing server 20 transmits information related to the search result display frame screen to the user terminal device 10, and uses the search formula input in the input box 53 as the user terminal device 10. The data is transmitted to the desktop search module 15a (S112).

  Based on the search formula received from the service providing server 20, the search execution unit 52 of the desktop search module 15a searches for an index file created in the background locally by the indexing unit 51 of the user terminal device 10, and The desktop search of the user terminal device 10 is executed, and the result of the desktop search is passed to the local web server 13 (S113). Then, the web browser 11 generates a screen combining the search result display frame screen 56 received from the service providing server 20 and the desktop search result 57 received from the local web server 13 and displays it as a desktop search result screen. Let

  FIG. 7 is an example of a desktop search result screen. As shown in FIG. 7, the user terminal device 10 displays a screen in which the search result display frame screen 56 received from the service providing server 20 is incorporated with the desktop search result 57 received from the local web server 13. Is done. This process inserts the information received from the local web server 13 using Java (registered trademark) script, iFrame, or the like into the portion where the desktop search result 57 is to be inserted in the data related to the search result display frame screen 56. This can be realized by setting so that

In this way, the user can input a search expression for desktop search and instruct execution of the search on the web page of the service providing server 20 when performing desktop search (search for local files). In addition, the result of the desktop search can be displayed by being incorporated in a screen frame provided by the service providing server 20.
That is, the domain name of the service providing server 20 is included in the URL of the page that displays the search result when the desktop search is performed, for example, “http://mixi.jp/.

  When receiving the web information acquisition page, the user terminal device 10 receives at least one or more contents registered in advance by the content acquisition unit 62 according to a description such as Java (registered trademark) script or iFrame embedded in the page. Content is acquired from another service providing server 30 (S121). Then, a screen obtained by synthesizing the content acquired from the other service providing server 30 on the content display frame screen included in the web information acquiring page received from the service providing server 20 is generated and used as a result screen of the web acquiring process. Display.

  FIG. 10 is an example of the result screen of the web acquisition process. As shown in FIG. 10, the user terminal device 10 displays content 67 and 67 (for example, CNN news articles) received from other service providing servers 30 on a content display frame screen 66 received from the service providing server 20. A screen with a headline and a free mail inbox) is displayed.

  In this way, any content acquired from a web service provided by another service providing server 30 can be displayed by being incorporated in a screen frame provided by the service providing server 20. As a result, the user can obtain the content of any other web service only by accessing the service providing server 20, and the convenience of the user is improved.

  Next, as another example of the module 15, a file sharing module 15c will be described. The file sharing module 15 c is a module for sharing files among members of the service providing server 20.

  Here, in this embodiment, the service providing server 20 is a server (hereinafter referred to as “SNS server 25”) that provides a social networking service (hereinafter referred to as “SNS”), and shares files among SNS members. It is preferable. The SNS server 25 includes a member information database (hereinafter referred to as “member DB”) 26. In the member DB 26, for each user, human relationship information indicating the degree of connection between the user and other users is recorded. Based on the human relationship information recorded in the member DB 26, the SNS server 25 establishes a friendship relationship such that the user A and the user B are “friends” or the user A and the user C are “friends of friends”. It can be recognized (extracted / calculated). In this embodiment, the data structure of the member DB 26 and the method for recognizing the friendship are not particularly shown, but any data structure and method for recognition can be adopted as long as the friendship between the users can be recognized. Needless to say.

  FIG. 11 is a block diagram illustrating a functional configuration of the file sharing module 15c. The file sharing module 15 c includes a shared folder 71 and a sharing processing unit 72.

  The shared folder 71 has a function as a shared folder for managing files shared with other users. The user designates a file to be shared and a sharing range of the file, and stores them in the shared folder 71. The sharing range indicates the degree of friendship of the SNS member who wants to share the file. For example, only the “friend” can share the file, the “friend of the friend” can share the file, It is possible to specify that “all members” are allowed to share files.

  The sharing processing unit 72 has a function of executing a process of sharing a file stored in the shared folder 71 with another user in cooperation with the SNS server 25. In particular, the SNS server 25 is notified of information about the file and the shared range stored in the shared folder 71, and the shared file is sent to the user terminal device 10 of the user in response to an instruction from the user that satisfies the shared range. Send.

  FIG. 12 is a flowchart showing the flow of file sharing processing by the file sharing module 15c. Here, a case where the user A opens the file sharing page of the SNS server 25 will be described as an example.

  First, each user preferably stores a file to be shared in the shared folder 71 of the user terminal device 10 used by each user. At this time, for each shared file, the shared range of the file is designated and stored in the shared folder 71.

  When the user A accesses the file sharing page of the SNS server 25 (S130), the SNS server 25 responds to the access from the shared folder 71 of all active users on the network N to the user A. On the other hand, files that are permitted to be shared are extracted, and a file list of the shared files is generated (S131). Then, the file list is transmitted to the user terminal device 10 (S132).

  FIG. 13 is an example of a file sharing screen. As shown in FIG. 13, the user terminal device 10 displays a screen in which a file list 77 of shared files is incorporated in the frame screen 76 received from the service providing server 20.

  Next, the file sharing process in the present embodiment will be described in detail with reference to FIGS.

  FIG. 14 is a diagram illustrating an example of a human relationship between members registered in the SNS server 25. Each node in FIG. 14 represents a user name, and a side connecting the nodes indicates that users at both end nodes of the side are in direct friendship. Therefore, in the example of FIG. 14, the user A is a friend with the user B, the user B is a friend with the users A, C, and E, and the user C is a friend with the users B and D. Further, the user A and the user C are in a relationship of “friends of friends”.

  FIG. 15 is a diagram illustrating an example of a file stored in the shared folder 71 of each of the users A to E illustrated in FIG. For example, three files are stored in the shared folder 71 of the user A, and the sharing ranges of “A1.doc” are only shared by friends, “A2.jpg” is only shared by friends of friends, “A3.mp3 Is set to be shared by all members. Further, the files stored in the shared folders 71 of the users B to D and their sharing ranges are set as shown in FIG. Furthermore, since the personal server software is not activated and the user E is not active, the shared folder 71 does not exist.

  16 is displayed to the user A when the user A opens the file sharing page of the SNS server 25 in the registration status of the shared folder 71 shown in FIG. 15 on the assumption of the human relationship shown in FIG. It is a figure which shows the file list 77 of the shared file to be performed. The SNS server 25 generates a list (file list 77) of files that the user A is allowed to share based on the shared files recorded in the shared folder 71 of each user (user terminal device 10) and the sharing range. To do.

  In the example shown in FIGS. 14 to 16, since the user A and the user B are direct friends, even if the sharing range is “friend”, “friend of friend”, or “entire”, the shared folder 71 Files stored in are shared. On the other hand, since the user A and the user C are “friends of friends”, the user A cannot share the file “C1.jpg” that the user C can share only with “friends”. Among the files stored in the shared folder 71 of the user C, the user A can share a file whose sharing range is “friends of friends” or “whole”. Further, since the user A and the user D are in a relationship of “friends of friends”, the user A can share only “D3.doc” that is permitted to be shared by all members. Also, since user E is not active, the file is not shared.

  In this way, file sharing between members registered in the SNS server 25 becomes possible. Further, it becomes possible to designate a file sharing range for each individual file based on friendship information between the members. This makes it easy to share files only between specific friends. Furthermore, since the user can set the file sharing range for each file, it becomes possible to control the risk of leakage of personal information of the user.

  As described above, according to the present embodiment, by operating personal server software, a local web server and one or more modules are configured in the user terminal device, and the local web server and modules provide online services. By performing processing in cooperation with the web server that performs the processing, it becomes possible to provide an online service that seamlessly cooperates with the user terminal device.

  The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the said embodiment is only a mere illustration in all points, and is not interpreted limitedly. For example, the above-described processing steps can be executed in any order or in parallel as long as there is no contradiction in the processing contents.

  For example, in the present embodiment, the personal server software is downloaded from the service providing server 20 and installed in the user terminal 10. However, the personal server software may be downloaded from another web server. Alternatively, the DVD may be distributed to users by storing it on a recording medium such as a DVD.

  In the third embodiment, the service providing server 20 is described as the SNS server 25. However, the service providing server 20 is not limited to the SNS server 25, and is applied to various web servers that provide other web services. It goes without saying that it is possible. Conversely, in the first and second embodiments, the service providing server 20 may be an SNS server.

  Furthermore, in the present embodiment, a desktop search module, a web acquisition module, and a file sharing module are illustrated as examples of modules, but it goes without saying that modules for providing other online services can be arbitrarily configured.
