In any case, it serves as an incentive to promote the creation and distribution of content for the user, and for the system provider, for example, in the latter case, the use of facilities is activated by the spread of points through the distribution of content Can be achieved.

[Action]
FIG. 4 is a flowchart showing a processing procedure for distributing content between the mobile terminals 2 in the system 1 configured as described above. An example of specific display corresponding to this processing procedure is shown in the conceptual diagram of FIG.

<Processing procedure of portable terminal 2a>
A processing procedure of the mobile terminal 2a will be described. Note that the processing procedure of the mobile terminals 2a and 2b described below is performed when the arithmetic control unit 21 of the mobile terminals 2a and 2b executes a program such as an application or script stored in the storage unit 22. This program is provided to the portable terminal 2 by the provider of the system 1 being transmitted from the server 3 via the network.

  First, the mobile terminal 2a performs content creation processing (step S11). In the content creation process, the mobile terminal 2a displays a creation form (not shown) on the display unit 25, and accepts input of various elements such as text and images constituting the content by the user. When an input is performed by the user via the input unit 24, content data including various elements for which the input has been performed is created.

  In the content creation process, the mobile terminal 2a accepts designation input of elements in the content to be invisible by the user. For example, a designation input may be received by displaying a pointer or the like on the display unit 25 and allowing the user to designate the range or area via the input unit 24. In other words, the invisibility target is an element such as a text area or an image, an element part such as a part of text or a part of an image, a combination of a plurality of elements, or an arbitrary shape specified by a rectangle or an ellipse, for example. Arbitrary designation is possible such as an element included in the range or a part of the element. Also, as the creation form of the display unit 25, an input field that is not to be invisible (for example, a title field) and an input field that is to be invisible (for example, a text input field) are displayed, and various elements for the input field that is to be invisible The designation input may be accepted with the input of. The portable terminal 2a creates invisibility target data that designates an element to be invisible based on a designation input by the user via the input unit 24.

  In the content creation process, the mobile terminal 2 a accepts input of price points by the user via the input unit 24.

  Next, the portable terminal 2a transmits the content data created in the content creation process, the invisible data, and the price point to the server 3 (step S12). In this processing procedure, the user of the mobile terminal 2a has already entered an authentication key such as a user ID or an authentication ID acquired exclusively through the input unit 24 and transmits the authentication key to the server 3, whereby login authentication is performed on the server side. Is assumed to have been performed.

<Processing procedure of server 3>
Next, the processing procedure of the server 3 will be described. In addition, the process procedure of the server 3 demonstrated below is performed when the calculation control part 31 of the server 3 runs the program memorize | stored in the memory | storage part 32. FIG.

  First, the server 3 receives the content data, the invisible data, and the price point transmitted from the mobile terminal 2a (step S21).

  Next, the server 3 performs invisibility processing, processes the content data, and creates invisible content data (step S22). Invisibility processing is performed by rewriting or masking elements such as text and images of content data specified by the data to be invisible to different replacement elements such as text and images, deleting from content data, encryption, etc. By performing this process, it is processed into other information to make it invisible. For example, the replacement element may be dynamically generated by the invisibility processing unit 34 performing image processing such as mosaic processing or blackening processing on the element to be invisible, or stored in the storage unit 32 in advance. May be. By performing the invisibility process, the content can be distributed while a part of the content cannot be visually recognized by the user.

  When the invisibility processing is completed, the server 3 issues the content data, the invisible content data, and the price point issued to the data area assigned to the user ID of the user of the mobile terminal 2a in the content DB 4 (FIG. 2). Store it linked to.

  Next, the server 3 transmits the invisible content data to the mobile terminal 2a (step S23). A content ID is associated with the invisible content data.

<Processing procedure of portable terminal 2a>
Next, the processing procedure of the mobile terminal 2a will be described. The portable terminal 2a receives the invisible content data from the server 3 and stores it in the storage unit 22 (step S13). Next, the portable terminal 2a searches for another portable terminal that is an opponent for ad hoc communication, and when the other portable terminal 2b that is the partner can be identified, transmits the invisible content data to the portable terminal 2b. (Step S14). The invisible content data to be transmitted can be determined in advance by receiving input from the user via the input unit 24 from the invisible content data stored in the storage unit 22.

<Processing procedure of portable terminal 2b>
Next, the processing procedure of the mobile terminal 2b will be described. The portable terminal 2b receives the invisible content data from the portable terminal 2a specified as the partner that performs the ad hoc communication, and stores it in the storage unit 22 (step S31).

  Next, the portable terminal 2b performs an invisible content display process (step S32). The portable terminal 2b displays the invisible content on the display unit 25 based on the invisible content data. The display unit 25 displays content that does not partially disclose elements such as text and images that are to be invisible. The user of the portable terminal 2b is made to determine whether to browse all of the content by checking elements such as text and images that are not made invisible and price points.

  In the invisible content display process, the mobile terminal 2b receives an input requesting browsing of all the content by the user. For example, an input can be received by displaying a browse request button or the like on the display unit 25 and causing the user to specify via the input unit 24.

  When the portable terminal 2b detects an input requesting browsing of the entire content by the user, the portable terminal 2b transmits a content browsing request to the server 3 (step S33). The content browsing request includes the content ID of the invisible content data. Note that in this processing procedure, the user of the portable terminal 2b has already entered an authentication key such as a user ID or a specially acquired authentication ID via the input unit 24 and transmits it to the server 3, whereby login authentication is performed on the server side. Is assumed to have been performed.

<Processing procedure of server 3>
Next, the processing procedure of the server 3 will be described. First, when the server 3 receives the content browsing request transmitted from the mobile terminal 2b (step S24), the server 3 performs point settlement processing (step S25).

  In the point settlement process, the server 3 acquires the user ID of the user of the mobile terminal 2b that has transmitted the content browsing request and the user ID of the user who created the content data associated with the content ID in the content DB 4. And the server 3 subtracts the price point linked | related with content ID from the possession point linked | related with the user ID of the user of the portable terminal 2b with respect to point management DB5, On the other hand, creation user's The price point associated with the content ID is added to the possession point associated with the user ID. The content ID for which settlement has been completed may be stored as a browsing permission history in the storage unit 32 and referred to when there is a subsequent browsing request.

  Next, the server 3 acquires content data associated with the content ID transmitted from the mobile terminal 2b from the content DB 4 (that is, performs DB collation using the content ID as a key), and the target for which a browsing request has been made. The content data is transmitted to the mobile terminal 2b (step S26).

<Processing procedure of portable terminal 2b>
Next, the processing procedure of the mobile terminal 2b will be described. The portable terminal 2b receives the content data from the server 3 and stores it in the storage unit 22 (step S34). At this time, the portable terminal 2b may delete the invisible content data stored in the storage unit 22, but transmits the invisible content data to the third terminal device (terminal device 2c). In addition, it is preferable not to delete in this case.

  Next, the portable terminal 2b performs content display processing (step S35). The portable terminal 2b displays all of the content on the display unit 25 based on the content data instead of the invisible content. The display unit 25 displays content that discloses elements such as text and images that have been made invisible. Thereby, the user of the portable terminal 2b can browse all the contents.

  When the mobile terminal 2a can receive the invisible content data from the mobile terminal 2b by the ad hoc communication in step S14 (that is, when the mobile terminal 2a has transmitted each other), the above-described steps S31 to S35 are also performed in the mobile terminal 2a. The processing procedure is similarly performed.

  As described above, according to the present embodiment, in the short-range communication performed between the mobile terminals 2 located within a certain communication range, the user of each mobile terminal 2 is a part of the elements including the text constituting the content. Exchanges invisible content that has been made invisible. Then, the mobile terminal 2 that has received the invisible content causes the display unit 10 to display the invisible content, and allows the user to determine whether or not the content is necessary based on elements that are not invisible. . Only when there was an intention to view the entire content, the entire content was displayed, and the price for using the content was paid. As a result, in the method of short-range communication performed between the mobile terminals 2 located within a certain communication range, when incorporating a content trading mechanism, it is possible to realize a transaction with improved soundness and reliability. Become.

  In addition, since the user is allowed to arbitrarily create the information that the user wants to send to other users and the price that the user wants to obtain, there is room for elaboration such as how to show them to attract purchases while hiding them from other users. This is suitable for activating the transaction.

  In addition, the said embodiment is only an illustration and this invention includes what is illustrated below and other embodiment other than that. For example, in this embodiment, the invisibility processing is performed on the server 3 side, but a configuration performed on the mobile terminal 2 side may be employed. In this case, a step for realizing the processing is included in a program such as an application provided to the mobile terminal 2. When it is performed on the mobile terminal 2 side, the load on the server 3 is reduced, and the traffic between the server 3 and the mobile terminal 2 can be reduced.

  In this embodiment, ad hoc communication using Bluetooth, WIFI, or the like is performed to realize near field communication between portable terminals located within a predetermined communication range. The mobile terminal 2 manages position information measured by the GPS (Global Positioning System) function of the mobile terminal 2 by the server 3 (may be a different server), and a mobile terminal located within a predetermined range geographically. It is also possible to adopt a technique for realizing near field communication in a pseudo manner by specifying and mediating the exchange of contents between portable terminals within the range.

  In addition, each element such as means relating to the present invention is not limited to an arithmetic control unit of a computer, but may be realized by other information processing mechanisms such as an electronic circuit based on wired logic or the like. Each configuration diagram, data diagram, flowchart diagram, and the like are merely examples, and the presence / absence of each element, the arrangement order thereof, the execution order of each process, specific contents, and the like can be appropriately changed. For example, the server device of the present invention may be realized by using a plurality of devices such as servers as constituent elements, and a configuration in which individual means are realized by separate and independent server devices is also common. Depending on the function, the configuration can be flexibly changed, for example, by calling an external platform or the like with an API (application program interface) or network computing (so-called cloud or the like).
