Description

  The present invention relates to an information processing apparatus, a data exchange method, and an information processing system.

  In recent years, with the spread of networks such as the Internet, information processing systems capable of sharing data among a plurality of devices via servers on the network have appeared.

  Under such circumstances, techniques relating to data sharing among a plurality of devices have been developed. For example, as a technology related to a server that selects users belonging to the same group based on a viewing information request transmitted from a content viewing device and transmits viewing information corresponding to the selected user to the content viewing device, for example, Patent Document 1 is cited.

JP 2009-124606 A

For example, the case where data (image data) of a photograph taken at an event such as a wedding is exchanged between users at a later date of the event is contrary to the potential needs for the exchange of data. Not many. The above is assumed to be due to the absence of means for directly transferring data between information processing apparatuses such as PCs (Personal Computers) owned by each user for the following reasons.
・ E-mail addresses are not necessarily exchanged between users ・ E-mail address of a device that is not suitable for receiving data even if the e-mail address of the transmission target user who wants to send data is known (for example, e-mail address of a mobile phone)・ It is practically impossible to send large amounts of data attached to e-mails. ・ Settings that allow data transmission / reception between information processing devices such as PCs owned by users ( For example, opening up services with each other) is not realistic

  In recent years, it has become possible to perform data with a larger capacity between devices by using a proximity wireless communication technology such as TransferJet (registered trademark). Therefore, when data is exchanged between users at the time of the event, there is a possibility that the frequency of data exchange at a later date of the event may be reduced. However, at the time of the event, it is practically difficult for the user who passes the data to select the data and transmit it to the user who receives the selected data. In addition, even if the proximity wireless communication technology as described above is used, there is a limit to the communication speed, so there is a possibility that the user may be forced to wait for a long time to complete transmission and reception of a large amount of data. There is a risk of reducing the convenience for the user.

  Therefore, even if it becomes possible to exchange data between users at the time of the event by using the proximity wireless communication technology, eventually, the data to be delivered or the data to be requested is not exchanged between the users. It will be. Therefore, a mechanism for assisting data exchange between users has been desired.

  Here, as the above-described mechanism, for example, communication with an information processing apparatus owned by each user is possible as in a conventional technique related to data sharing among a plurality of apparatuses (hereinafter referred to as “conventional technique”). Data transmission / reception may be performed through a server. As described above, since data transmission / reception is performed via the server, there is no need to directly transmit / receive data between information processing apparatuses owned by each user. There is a possibility that data transmission / reception using data can be assisted.

  However, since the conventional technique is a technique for sharing viewing information of users in the same group registered in advance, when using the conventional technique, each user who exchanges data registers with the server. There must be. Therefore, when the conventional technique is used, the user registration operation to the server is forced to exchange data, which may reduce the convenience for the user. Therefore, even if the conventional technique is used, it is not desirable to assist the exchange of data between users.

  The transmission candidate setting unit sets a priority for each data that is a candidate for data to be transmitted based on the promise information, and a transmission screen on which data candidates to be transmitted are displayed according to the set priority. May be displayed on the display screen.

  The auxiliary information is image data including a user's face part to which the data is exchanged, and the transmission candidate setting unit adds the auxiliary information to the image data that is a candidate for data to be transmitted. Face detection may be performed using an image of the included face portion, and the priority may be set for each of the image data that is a candidate for data to be transmitted based on the result of face detection.

  In addition, the transmission candidate setting unit identifies image data including a user to whom data is to be exchanged by the face detection, and assigns the priority of the image data including the user to which the data is to be exchanged to a person May be set higher than the priority of image data that does not include the user to whom the data is to be exchanged.

  In addition, the transmission candidate setting unit identifies image data including a user to whom the data is exchanged by the face detection, and the person includes the priority of the image data not including the person. May be set higher than the priority of the image data that does not include the user to whom the data is exchanged.

  Further, the promise information may include information on a time when the exchange information is exchanged, and the transmission candidate setting unit may set a candidate for data to be transmitted based on the time information. .

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

In the following, description will be given in the following order.
1. 1. Approach according to an embodiment of the present invention 2. Information processing system according to an embodiment of the present invention Program according to the embodiment of the present invention

(Approach according to the embodiment of the present invention)
Information processing apparatus (hereinafter, collectively referred to as “information processing apparatus 100”) that constitutes an information processing system according to an embodiment of the present invention (hereinafter may be referred to as “information processing 1000”). Before explaining the configuration of a server (hereinafter sometimes referred to as “server 200”), a data transfer assistance approach according to an embodiment of the present invention will be described.

[Outline of Data Transfer Support Approach]
As described above, there is a possibility that data exchange between users can be assisted by transmitting and receiving data between information processing apparatuses owned by each user via a server. In addition, when the user is forced to register with the server as in the case of using the conventional technology, there is a possibility that the user's convenience may be reduced. Therefore, it is desirable to assist the exchange of data between users. Not possible.

  Therefore, in the information processing system 1000 to which the data transfer assist approach is applied, each information processing apparatus 100 owned by the user who transmits and receives data generates authentication information based on the promise information. In the information processing system 1000, each information processing apparatus 100 records data in the server 200 and / or receives data from the server 200 using the generated authentication information.

  Here, the promise information according to the embodiment of the present invention is information for exchanging data promised between users. The promise information includes, for example, exchange information exchanged in advance between users, information on the time when the exchange information was exchanged, and an information processing apparatus 100 (hereinafter referred to as “information processing apparatus 100A”) used by one user to exchange data. Identification information (hereinafter, sometimes referred to as “first identification information”).

  The first identification information according to the embodiment of the present invention is appropriately generated in an apparatus used by one user when exchanging exchange information, for example, when exchanging exchange information. Here, as the first identification information, for example, hash information generated from image data arbitrarily selected from image data stored in an apparatus used by the one user when exchanging the exchange information can be cited. For example, a device used by the one user when exchanging exchange information uses hash information generated from arbitrary stored data as first identification information. Needless to say, the apparatus used by the one user when exchanging exchange information may be, for example, the information processing apparatus 100A.

  Further, as the exchange information, for example, the server 200 identifies the information processing apparatus 100 (hereinafter, also referred to as “information processing apparatus 100B”) used by other users who are data transmission / reception objects for data transmission / reception. It includes identification information (hereinafter sometimes referred to as “second identification information”) and auxiliary information for specifying other users to whom data is exchanged.

  The second identification information according to the embodiment of the present invention is appropriately generated in, for example, an apparatus used when another user exchanges exchange information when exchanging exchange information. Here, as the first identification information, for example, the second identification information is generated from image data arbitrarily selected from the image data stored in the device used by the other user when exchanging the exchange information. Hash information. Needless to say, the apparatus used by other users when exchanging exchange information may be, for example, the information processing apparatus 100B.

  In addition, as auxiliary information according to the embodiment of the present invention, for example, character data corresponding to a secret word between users who exchange data, or image data (hereinafter referred to as “compound image”) serving as a secret word. May be called)). By exchanging auxiliary information according to the embodiment of the present invention between users (strictly, between devices owned by the user), which user has promised to exchange data (i.e. It is possible to uniquely identify a user to whom data is exchanged. Note that the combined image according to the embodiment of the present invention serves as a business card, for example. Examples of the combined image according to the embodiment of the present invention include image data created in advance by the user.

  More specifically, the information processing apparatus 100 generates authentication information based on the first identification information and the second identification information. Here, the exchange information exchanged between users includes identification information generated on the other user side to which data is exchanged. Therefore, each information processing apparatus 100 can use the same first identification information and second identification information by using the promise information including the exchange information. For example, the information processing apparatus 100 generates hash information based on the first identification information and the second identification information, and uses the generated hash information as authentication information. As described above, the first identification information and the second identification information according to the embodiment of the present invention are hash information generated from arbitrary data, and thus are based on the first identification information and the second identification information. It is difficult for a third party other than the user who exchanges data to copy the hash information. Accordingly, each information processing apparatus 100 records data in the server 200 and / or receives data from the server 200 using the authentication information generated as described above, thereby allowing a specific information device 100 to Indirect data transmission / reception can be realized.

  In addition, when transmitting data to the server 200 (corresponding to passing data to another user), the information processing apparatus 100 transmits the data to be transmitted and authentication information in association with each other. Then, the server 200 that has received the data and the authentication information transmitted from the information processing apparatus 100 records the received data and the authentication information in association with each other. In addition, when the information processing apparatus 100 transmits the data and the authentication information, the information transmitted to the server 200 is transmitted from which information processing apparatus by transmitting the identification information for identifying the own apparatus together. It can be recorded together. Here, the identification information corresponds to first identification information when viewed from the information device 100 on the data transmission side, and corresponds to second identification information when viewed from the information processing device 100 on the data reception side.

  Further, when receiving data from the server 200 (corresponding to receiving data from another user), the information processing apparatus 100 sends a data transmission request for requesting the server 200 to transmit data and authentication information. Send to server 200. Then, the server 200 that has received the data transmission request and the authentication information transmitted from the information processing apparatus 100 detects data that matches the authentication information from the stored data, and transmits the detected data to the data transmission The request is transmitted to the information processing apparatus 100 that has transmitted the request. Here, the selective transmission of data matching the authentication information in the server 200 corresponds to an authentication process using the authentication information. The data transmission request includes, for example, identification information that identifies the information processing apparatus 100 that transmits the data transmission request. Here, the identification information included in the data transmission request corresponds to the first identification information when viewed from the information device 100 on the transmission side of the data transmission request, and from the other information processing device 100 that has transmitted data to the server 200. Corresponds to second identification information.

  In the information processing system 1000, for example, data transmission / reception is performed between the information processing apparatus 100A and the information processing apparatus 100B via the server 200 as described above. Here, in the information processing system 1000, transmission / reception of data between the information processing apparatus 100A and the information processing apparatus 100B via the server 200 is performed using authentication information based on the promise information. Therefore, in the information processing system 1000, even if the user does not perform another registration related to data transmission / reception with respect to the server 200, the data transmitted by another user to whom data is to be transmitted / received using the information processing apparatus 100. Can be received indirectly via the server 200.

  When the information processing system 1000 is used, for example, exchange information (data) exchanged between devices owned by a user who promises to exchange data at an event venue is second identification information and auxiliary information, for example. Therefore, the user can save time and effort for selecting data to be transmitted, compared to transmitting a photograph (image data) taken at an event venue, for example. In addition, since the second identification information is hash information and the auxiliary information is character data or image data, for example, by using the proximity wireless communication technology, a short time is required between devices possessed by a user who promises to exchange data. Transmission / reception is completed in (for example, several seconds). Therefore, when the information processing system 1000 is used, for example, even if exchange information is exchanged between devices owned by a user who promises to exchange data at an event venue or the like, the user is not forced to have a special waiting time. Therefore, there is no fear of reducing the convenience for the user.

  Therefore, the information processing system 1000 including the information processing apparatus 100 and the server 200 can assist data exchange between users.

[Processing related to data transfer assistance approach]
Next, an example of processing related to the data exchange assistance approach according to the embodiment of the present invention described above in the information processing system 1000 will be described. FIG. 1 is an explanatory diagram showing an example of an information processing system 1000 according to an embodiment of the present invention. The information processing system 1000 includes an information processing apparatus 100A, an information processing apparatus 100B, and a server 200.

  Hereinafter, a case where data is exchanged between the user A and the user B will be described as an example. The information processing apparatus 100 used by the user A for data exchange is the information processing apparatus 100A, and the user B Description will be made assuming that the information processing apparatus 100 used for data exchange is the information processing apparatus 100B. In FIG. 1, the information processing terminal 300A is shown as an apparatus used by the user A for exchanging exchange information at an event venue or the like, and the information processing terminal 300B is shown as an apparatus used by the user B for exchanging exchange information. In FIG. 1, the information processing apparatus 100 </ b> A and the information processing terminal 300 </ b> A used by the user A are illustrated as different apparatuses, but the present invention is not limited to the above. For example, the information processing apparatus 100A and the information processing terminal 300A may be the same apparatus. The same applies to the information processing apparatus 100B and the information processing terminal 300B used by the user B. Hereinafter, the information processing terminal 300A and the information processing terminal 300B may be collectively referred to as “information processing terminal 300”.

  Hereinafter, processing related to the data transfer assistance approach in the information processing system 1000 illustrated in FIG. 1 will be described. In the following, when user A transmits data to server 200 using information processing apparatus 100A and user B receives data from server 200 using information processing apparatus 100B (that is, user A passes the data). The side where the user B receives data) will be mainly described as an example. Note that both of the information processing apparatus 100A and the information processing apparatus 100B according to the embodiment of the present invention may perform data transmission / reception via the server 200 by performing processing related to the data exchange assist approach described below. Needless to say, what you can do.

  FIG. 2 is an explanatory diagram illustrating an example of processing related to the data transfer assistance approach in the information processing system 1000 according to the embodiment of the present invention. FIG. 2 also shows processing related to transmission / reception of exchange information (exchange information exchange) between the information processing terminal 300A and the information processing terminal 300B at an event venue or the like. Further, FIG. 2 shows a case where data (data exchanged between the user A and the user B) transmitted and received by the information processing apparatus 100A and the information processing apparatus 100B via the server 200 is image data. Note that data transmitted and received by the information processing apparatus 100A and the information processing apparatus 100B via the server 200 is not limited to image data. For example, the information processing apparatus 100A and the information processing apparatus 100B can transmit and receive various data such as document data and audio data (or music data) via the server 200.

  When the exchange of image data is promised between the user A and the user B and the information processing terminal 300A and the information processing terminal 300B are communicable, the information processing terminal 300A includes the first identification information and the first auxiliary information. Information is transmitted to the information processing terminal 300B (S100). Here, the information processing terminal 300 </ b> A generates the first identification information based on, for example, arbitrary data (for example, image data) stored in a recording medium included in the apparatus or a removable external recording medium. Further, the information processing terminal 300A transmits, for example, data preset as auxiliary information as the first auxiliary information. Note that the first identification information and the first auxiliary information transmitted from the information processing terminal 300A in step S100 correspond to the second identification information and the second auxiliary information when viewed from the information processing terminal 300B side. In addition, the information processing terminal 300 </ b> A can also transmit auxiliary information selected by a user operation among the set auxiliary information as first auxiliary information. When a plurality of pieces of auxiliary information are set in the information processing terminal 300A, for example, each user uses the information processing system 1000 while sharing the information processing terminal 300A with a plurality of users (for example, family members and groups). Data can be transmitted and received.

  The information processing terminal 300B that has received the first identification information and the first auxiliary information transmitted from the information processing terminal 300A in step S100 performs the same processing as in step S100 in the information processing terminal 300A, and the second identification information and the first information 2 The auxiliary information is transmitted to the information processing terminal 300A (S102). Note that the second identification information and the second auxiliary information transmitted from the information processing terminal 300B in step S102 correspond to the first identification information and the first auxiliary information when viewed from the information processing terminal 300B side.

  By performing the processing of Step S100 and Step S102, the information processing terminal 300A and the information processing terminal 300B store the first identification information and the second identification information, respectively, and exchange auxiliary information stored by each other. be able to.

  The information processing terminal 300A transmits the first identification information, the second identification information, the second auxiliary information, and one or more image data that are candidates for transmission to the server 200 to the information processing apparatus 100A (S104). . Here, the first identification information, the second identification information, and the second auxiliary information correspond to the promise information used by the information processing apparatus 100A for processing. Also, the information processing apparatus 100A uses, for example, a time stamp indicating the time when the first identification information is generated as information about the time when the exchange information is exchanged. Note that the information processing apparatus 100A can also use, for example, the time stamp of the second auxiliary information as information on the time when the exchange information is exchanged.

  Although FIG. 1 shows an example in which the information processing terminal 300A transmits the first identification information, the second identification information, and the second auxiliary information to the information processing apparatus 100, it is not limited to the above. For example, the information processing terminal 300 </ b> A can transmit the first identification information, the second identification information, and the second auxiliary information to the information processing apparatus 100 as one data object (an example of promise information). In the above case, the information processing apparatus 100A uses, for example, the time stamp of the data object as information on the time when the exchange information is exchanged.

  When the first identification information, the second identification information, the second auxiliary information, and the image data are received in step S104, the information processing apparatus 100A generates authentication information based on the first identification information and the second identification information ( S106).

  The information processing apparatus 100A displays a transmission screen on which the content of the auxiliary information and the candidate data to be transmitted are displayed on the display screen. Then, the information processing apparatus 100A determines whether or not to transmit image data to the server 200 based on, for example, a user operation on the transmission screen (S108; transmission determination process).

  FIG. 3 is an explanatory diagram illustrating an example of a transmission screen displayed on the display screen by the information processing apparatus 100A according to the embodiment of the present invention. As illustrated in FIG. 3, the information processing apparatus 100 </ b> A includes, for example, an image (A in FIG. 3, an example of the content of auxiliary information) indicating a user to whom data is exchanged, and a list of image data that is transmission candidates ( B. An example of a candidate for data to be transmitted), a transmission button (C in FIG. 3) serving as a trigger for the information processing apparatus 100A to transmit data is displayed on the transmission screen.

  Here, FIG. 3 shows an example of a transmission screen when the second auxiliary information is image data (combined image), and the information processing apparatus 100A displays the combined image indicated by the second auxiliary information in FIG. The data shown in A is displayed as an image showing a user to whom data is exchanged. When the second auxiliary information is not a password image but, for example, character data indicating a secret word, the information processing apparatus 100A displays the character (password) indicated by the second auxiliary information on the transmission screen.

  In addition, the information processing apparatus 100A sets, for example, a priority for each data that is a candidate for data to be transmitted based on the promise information, and a transmission screen on which data candidates to be transmitted are displayed according to the set priority. Is displayed on the display screen. Here, as a transmission screen on which candidates for data to be transmitted according to the set priority are displayed, for example, image data having a high priority is displayed in a list of image data to be transmission candidates shown in FIG. Examples include a transmission screen displayed at the top and a transmission screen in which high-priority image data is emphasized. As a method for emphasizing image data having a high priority, for example, as shown in F1 and F2 in FIG. 3, a frame is set for image data candidates displayed in a list.

  The information processing apparatus 100A sets the priority based on, for example, auxiliary information. More specifically, in the information processing apparatus 100A, for example, when the second auxiliary information is image data (composite image) including the face portion of the user who is the object of data transfer as shown in A of FIG. Image data including a user to be exchanged is specified by face detection using an image of a face portion included in the combined image. Then, the information processing apparatus 100A determines the priority of the image data including the user who is the object of data transfer, and the priority of the image data including the person but does not include the user who is the object of data transfer. Set higher than. In addition, even if image data does not include a user to whom data is to be exchanged, even if image data that does not include a person such as a landscape is transmitted, there is no particular problem. For example, 100A sets the priority of image data that does not include a person higher than the priority of image data that includes a person but does not include a user to whom data is exchanged.

  The information processing apparatus 100A displays on the display screen a transmission screen on which data candidates to be transmitted according to the set priority are displayed. Can assist with selection.

  Also, the information processing apparatus 100A sets data candidates to be transmitted based on, for example, information on the time when the exchange information included in the promise information is exchanged. More specifically, the information processing apparatus 100A, for example, based on the time information included in the promise information and a time stamp of data stored in a storage unit (described later) included in the information processing apparatus 100A, for example, Data that matches the date indicated by the time information and the date of the time stamp is set as a data candidate to be transmitted. The information processing apparatus 100A can also set data stored in an external recording medium from which the information processing apparatus 100A can read data as a candidate for data to be transmitted (hereinafter the same).

  Note that the method of setting candidates for data to be transmitted in the information processing apparatus 100A is not limited to the above. For example, the information processing apparatus 100A can set data including a date of a time stamp within a predetermined period including the date indicated by the time information as a candidate for data to be transmitted.

  Further, the method for setting the candidate for data to be transmitted in the information processing apparatus 100A is not limited to setting the candidate for data to be transmitted based on the information on the time when the exchange information included in the promise information is exchanged. For example, the information processing apparatus 100A can also set data candidates to be transmitted for each set period or date based on the period or date set by the user operation of the user A. As described above, the information processing apparatus 100A can set data candidates to be transmitted by grouping, for example, for each specific event.

  FIG. 4 is an explanatory diagram illustrating another example of a transmission screen displayed on the display screen by the information processing apparatus 100A according to the embodiment of the present invention. Here, FIG. 4 illustrates an example of a transmission screen when the information processing apparatus 100A sets data candidates to be grouped and transmitted for each specific event. As illustrated in FIG. 4, when setting data candidates to be grouped and transmitted for each specific event, the information processing apparatus 100 </ b> A, for example, sets a set period or date as illustrated in D of FIG. 4. Can be selected by the cursor SEL. Then, the information processing apparatus 100A sets the transmission candidate corresponding to the selected period or date to the transmission candidates shown in B of FIG. 4 in the same manner as the list of image data to be transmission candidates shown in B of FIG. Is displayed in the list of image data.

  In addition, the information processing apparatus 100A includes the person in each set period or the like by face detection using the face information of the person included in the combined image (an example of auxiliary information) illustrated in A of FIG. It is possible to determine whether there is image data to be displayed, and to change a display method such as a set period according to the determination result. For example, FIG. 4D shows an example in which an event “2011.03.24” having no image data corresponding to the combined image shown in A of FIG. 4 is displayed separately from other events.

  In the transmission determination process in step S108, the information processing apparatus 100A displays, for example, the transmission screen illustrated in FIG. 3 or 4 on the display screen, and determines whether to transmit data based on a user operation. Needless to say, the transmission screen displayed on the display screen by the information processing apparatus 100 </ b> A according to the embodiment of the present invention is not limited to the examples illustrated in FIGS. 3 and 4.

[Example of transmission determination processing]
Here, an example of the transmission determination process in the information processing apparatus 100A will be described more specifically. FIG. 5 is a flowchart showing an example of the transmission determination process in the information processing apparatus 100A according to the embodiment of the present invention, and shows an example of the transmission determination process when the information processing apparatus 100A transmits image data. In the following description, it is assumed that the information processing apparatus 100A performs the process shown in FIG. 5, but the information processing apparatus 100B can perform the same process.

  The information processing apparatus 100A groups, for example, image data stored in a storage unit (described later) (S200). Here, the information processing apparatus 100 </ b> A performs the process of step S <b> 200 by classifying (for example, event clustering) based on the type stamp of the image data, for example. In addition, the information processing apparatus 100A assigns a sequential group number to each group.

  When grouping is performed in step S200, the information processing apparatus 100A sets a value of m (m is an integer) indicating a group number to m = 1 (S202). Here, the process of step S202 corresponds to an initialization process of the value of m.

The information processing apparatus 100A sets an evaluation value for each of the image data classified into the m groups based on the auxiliary information (S204). Here, the information processing apparatus 100A sets the evaluation value by performing face detection on the image indicated by each image data, for example, by performing face detection using the image of the face part included in the combined image as auxiliary information. . Also, the information processing apparatus 100A sets, for example, the following evaluation values for each image data.
An image including a user to be exchanged (a person corresponding to the face image included in the combined image): evaluation value = 1
-Image not including a person: Evaluation value = 2
An image that includes a person but does not include a user to be exchanged: Evaluation value = 0

  When an evaluation value is set for each image data of m groups in step S204, information processing apparatus 100A determines whether or not “m ≧ number of groups” (S206).

  If it is not determined in step S206 that “m ≧ number of groups”, the information processing apparatus 100A updates the value of m to m = m + 1 (S208), and repeats the processing from step S204.

  If it is determined in step S206 that “m ≧ number of groups”, the information processing apparatus 100A performs a priority setting process for setting a priority for each image data (S208).

<Example of priority setting process>
FIG. 6 is a flowchart showing an example of priority setting processing in the information processing apparatus 100A according to the embodiment of the present invention. In the following description, it is assumed that the information processing apparatus 100A performs the process illustrated in FIG. 6, but the information processing apparatus 100B can perform the same process.

  The information processing apparatus 100A determines whether there is image data including a user to be exchanged (a person corresponding to the face image included in the combined image) (S300). Here, the information processing apparatus 100 </ b> A performs the determination in step S <b> 300 based on the evaluation value set in step S <b> 204 in FIG. 5, for example. Note that the information processing apparatus 100 </ b> A can perform the determination in step S <b> 300 by performing face detection based on auxiliary information again for each image data stored in a storage unit (not shown), for example.

  If it is not determined in step S300 that there is image data including the user to be exchanged, the information processing apparatus 100A sets the priority of all image data that are candidates for data to be transmitted to “low” (S320). ). Then, the information processing apparatus 100A ends the priority setting process.

  When it is determined in step S300 that there is image data including the user to be exchanged, the information processing apparatus 100A sets the value of n (n is an integer) indicating a value serving as a counter to n = 1 is set (S302). Here, the process of step S302 corresponds to an initialization process of the value of n.

  The information processing apparatus 100A selects the nth image data from, for example, a storage unit (not shown) (S304). When image data is selected in step S304, the information processing apparatus 100A determines whether the selected image data is image data belonging to a group based on promise information (the information on the time included in the promise information). Determination is made (S306).

  If it is determined in step S306 that the image data belongs to the group based on the promise information (the time information included in the promise information), the information processing apparatus 100A determines the evaluation value set in step S204 of FIG. The priority is set based on (S308). For example, the information processing apparatus 100 sets the priority to “high” when the evaluation value is “1” or “2”, and sets the priority to “low” when the evaluation value is “0”. Set.

  When the priority is set in step S308, the information processing apparatus 100 determines whether the value of n is “n ≧ number of image data” (S310). Here, the number of image data in step S310 is, for example, the number of image data stored in a storage unit (described later) (that is, the number of data serving as transmission candidates).

  If it is determined in step S310 that “n ≧ the number of image data”, the information processing apparatus 100A ends the priority setting process.

  If it is determined in step S310 that “n ≧ the number of image data”, the information processing apparatus 100A updates the value of n to n = n + 1 (S312), and step S304. Repeat the process from.

  If it is not determined in step S306 that the image data belongs to the group based on the promise information (the time information included in the promise information), the information processing apparatus 100A determines whether the image data has been transmitted. It is determined whether or not (S314). Here, for example, every time data is transmitted to the server 200, the information processing apparatus 100A associates data to be transmitted with information on a user to be transmitted (for example, auxiliary information itself or information on a face portion). Record history information. Then, the information processing apparatus 100A performs the determination in step S314 by using the history information, for example.

  If it is determined in step S314 that the image data has already been transmitted, the information processing apparatus 100A sets the priority based on the evaluation value set in step S204 of FIG. 5 (S316). Then, the information processing apparatus 100A performs the process of step S310. For example, the information processing apparatus 100 sets the priority to “medium” when the evaluation value is “1” or “2”, and sets the priority to “low” when the evaluation value is “0”. Set.

  If it is not determined in step S314 that the image data has been transmitted, the information processing apparatus 100A sets the priority to “low”. Then, the information processing apparatus 100A performs the process of step S310.

  The information processing apparatus 100 </ b> A can set a priority for each image data that is a transmission candidate, for example, by performing the processing illustrated in FIG. 6. Needless to say, the priority setting process in the information processing apparatus 100A according to the embodiment of the present invention is not limited to the process illustrated in FIG.

  With reference to FIG. 5 again, an example of the transmission determination process in the information processing apparatus 100A according to the embodiment of the present invention will be described. When the priority setting process is performed in step S208, the information processing apparatus 100A displays, for example, a transmission screen as illustrated in FIGS. 3 and 4 on the display screen based on the set priority (S212).

  When the transmission screen is displayed on the display screen in step S212, the information processing apparatus 100A determines whether a transmission operation (an example of a user operation) has been detected (S214). Here, the information processing apparatus 100 determines that a transmission operation (an example of a user operation) has been detected when an operation signal generated by an operation unit (described later) in response to a user operation is detected. Then, the information processing apparatus 100A determines that transmission is performed when it is determined that a transmission operation has been detected (S216), and the transmission determination process ends.

  The information processing apparatus 100A can determine whether or not to transmit image data to the server 200 based on a user operation, for example, by performing the processing illustrated in FIG. Note that the transmission determination process in the information processing apparatus 100A according to the embodiment of the present invention is not limited to the process illustrated in FIG. For example, although not shown in FIG. 5, the information processing apparatus 100 </ b> A determines that transmission is not performed based on a transmission cancel operation by the user in the transmission determination process, and changes the transmission screen displayed on the display screen to another It is possible to transition to a screen (for example, a desktop screen). Further, even when the transmission screen is transitioned to another screen as described above, the information processing apparatus 100A causes the transmission screen to be displayed again on the display screen based on a user operation for displaying the transmission screen. It goes without saying that we can do it.

  With reference to FIG. 2 again, an example of processing related to the data transfer assistance approach in the information processing system 1000 according to the embodiment of the present invention will be described. If it is determined in step S108 that image data is to be transmitted to the server 200, the information processing apparatus 100A sends the first identification information, the authentication information, and the image data (the image data selected on the transmission screen) to the server 200. Transmit (S110). Here, the information processing apparatus 100A may encrypt each data to be transmitted using, for example, authentication information based on the promise information as an encryption key, and transmit the encrypted data to the server 200. As described above, the information processing apparatus 100B generates the same authentication information as the information processing apparatus 100A by using the promise information. That is, the information processing apparatus 100B has the same encryption key as the encryption key related to the encryption of the information processing apparatus 100A. Therefore, the information processing apparatus 100A transmits the data encrypted with the authentication information as the encryption key in step S110 to the server 200, so that the security can be further improved.

  The information processing apparatus 100 </ b> A can transmit, to the server 200, image data that the user A desires to pass to the user B, for example, by performing the processes of steps S <b> 106 to S <b> 110.

  The server 200 that has received the first identification information, the authentication information, and the image data transmitted from the information processing apparatus 100A in step S110 records the received authentication information and the image data in association with each other (S112). Further, the server 200 further records the image data and the first identification information in association with each other, for example. Here, the server 200 stores, for example, received image data in a storage unit (described later) included in the server 200. Note that the server 200 can also store received image data or the like in a removable external recording medium, an external storage device connected via a network, or the like (hereinafter the same).

  Next, processing in which the information processing apparatus 100B receives image data recorded in the server 200 will be described. The information processing terminal 300B transmits the first identification information, the second identification information, and the first auxiliary information to the information processing apparatus 100B (S114). Here, the first identification information, the second identification information, and the first auxiliary information correspond to the promise information used by the information processing apparatus 100B for processing. In addition, the information processing apparatus 100B uses, for example, a time stamp indicating the time when the second identification information is generated as information about the time when the exchange information is exchanged, but is not limited thereto. For example, the information processing apparatus 100B can use the time stamp of the first auxiliary information as information about the time when the exchange information is exchanged. Although not shown in FIG. 2, the information processing terminal 300 </ b> B can also transmit one or more image data that are candidates for transmission to the server 200 to the information processing apparatus 100 </ b> B.

  The information processing apparatus 100B that has received the first identification information, the second identification information, and the first auxiliary information transmitted from the information processing terminal 300B in step S114 receives the first identification in the same manner as the process of step S106 in the information processing apparatus 100A. Authentication information is generated based on the information and the second identification information (S116).

  The information processing apparatus 100B transmits a reception candidate transmission request for requesting transmission of information related to data that is a reception candidate and the authentication information generated in step S116 to the server 200 (S118). Here, the information processing apparatus 100B performs the process of step S118 based on, for example, a user operation, but is not limited to the above, and can be automatically performed after the process of step S116.

  The server 200 that has received the reception candidate transmission request and the authentication information transmitted from the information processing apparatus 100B in step S118 determines whether to transmit candidate data corresponding to the reception candidate transmission request (S120). Here, for example, based on the authentication information received in step S118, the server 200 selects image data that matches the authentication information from among image data stored in a storage unit (described later) provided in the server 200. To detect. Then, when image data that matches the authentication information is detected, the server 200 determines to transmit candidate data corresponding to the reception candidate transmission request.

  If it is determined in step S120 that candidate data corresponding to the reception candidate transmission request is transmitted, the server 200 transmits the candidate data to the information processing apparatus 100B (S122). Here, for example, the server 200 generates a thumbnail image based on the image data detected in step S120, and transmits the generated thumbnail image data as candidate data to the information processing apparatus 100B.

  The information processing apparatus 100B that has received the candidate data transmitted from the server 200 in step S122 displays a reception screen on which the received candidate data and the content of auxiliary information corresponding to the candidate data are displayed on the display screen. The information processing apparatus 100B determines whether or not to receive image data from the server 200 based on, for example, a user operation on the reception screen (S124; reception determination process).

  FIG. 7 is an explanatory diagram illustrating an example of a reception screen displayed on the display screen by the information processing apparatus 100B according to the embodiment of the present invention. As illustrated in FIG. 7, the information processing apparatus 100 </ b> B includes, for example, an image (E in FIG. 7, an example of the content of auxiliary information) indicating a user to whom data is exchanged and a list of image data to be received (in FIG. 7. F. An example of the received candidate data), a transmission button (G in FIG. 7) serving as a trigger for the information processing apparatus 100B to receive data from the server 200 is displayed on the reception screen.

  Here, FIG. 7 shows an example of a reception screen when the first auxiliary information is image data (composite image). The information processing apparatus 100B displays the composite image indicated by the first auxiliary information in FIG. It displays as an image which shows the user of the exchange object of the data shown to E. Note that when the first auxiliary information is not a password image but character data indicating a secret word, for example, the information processing apparatus 100B displays the character (password) indicated by the first auxiliary information on the reception screen.

  In the reception determination process in step S124, the information processing apparatus 100B displays, for example, the reception screen illustrated in FIG. 7 on the display screen, and determines whether to receive data from the server 200 based on a user operation. Needless to say, the reception screen displayed on the display screen by the information processing apparatus 100B according to the embodiment of the present invention is not limited to the example shown in FIG.

  If it is determined in step S124 that image data is to be received from the server 200, the information processing apparatus 100B transmits a data transmission request for requesting transmission of the image data selected on the reception screen and authentication information to the server 200. (S126).

  The server 200 that has received the data transmission request and the authentication information transmitted from the information processing apparatus 100B in step S126 determines whether or not to transmit image data corresponding to the data transmission request (S128). Here, for example, based on the authentication information received in step S126, the server 200 selects image data that matches the authentication information from among image data stored in a storage unit (described later) provided in the server 200. To detect. Then, the server 200 determines that image data corresponding to the data transmission request is to be transmitted when image data that matches the authentication information is detected.

  Then, the server 200 transmits the image data detected in step S128 to the information processing apparatus 100B that transmitted the data transmission request (S130).

  The information processing apparatus 100B can receive, from the server 200, image data that the user A desires to pass to the user B by performing the processes of steps S116, S118, S124, and S126, for example.

  In the information processing system 1000, for example, the processing shown in FIG. 2 is performed, whereby indirect data transmission / reception between the information processing apparatus 100A and the information processing apparatus 100B via the server 200 is realized.

  Here, in the information processing system 1000, transmission / reception of data between the information processing apparatus 100A and the information processing apparatus 100B via the server 200 is performed using authentication information based on the promise information. Therefore, in the information processing system 1000, even if the user does not perform another registration related to data transmission / reception with respect to the server 200, the data transmitted by another user to whom data is to be transmitted / received using the information processing apparatus 100. Can be received indirectly via the server 200.

  Further, in the information processing system 1000, the identification information (first identification information, second identification information) used by the information processing apparatus 100A and the information processing apparatus 100B for generating authentication information is as shown in steps S100 and S102 in FIG. For example, it is exchanged between the information processing terminals 300A and 300B at an event venue or the like. Here, as shown in steps S100 and S102 of FIG. 2, since the exchange information exchanged between the information processing terminals 300A and 300B is the identification information and the auxiliary information, the information processing terminals 300A and 300B, for example, at an event venue or the like. Even if exchange information is exchanged between users, user A and user B are not forced to have a special waiting time. Therefore, when exchanging exchange information related to the generation of authentication information, there is no risk of reducing user convenience.

  Therefore, the information processing system 1000 can assist data exchange between users by performing, for example, the processing illustrated in FIG. 2 in the information processing apparatus 100A, the information processing apparatus 100B, and the server 200.

  2 illustrates an example in which the information processing apparatus 100A transmits image data to the server 200 and the information processing apparatus 100B receives image data from the server 200, but the present invention is not limited thereto. As described above, in the information processing system 1000, the information processing apparatus 100B can transmit image data to the server 200, and the information processing apparatus 100A can receive image data from the server 200. In the information processing system 1000, data that is indirectly transmitted and received between the information processing apparatus 100A and the information processing apparatus 100B is not limited to image data, and the information processing apparatus 100A and the information processing apparatus 100 store arbitrary data. It can be transmitted and received indirectly via the server 200.

  Further, the process related to the data transfer assistance approach in the information processing system 1000 according to the embodiment of the present invention is not limited to the process shown in FIG. For example, when the server 200 stores data transmitted from both the information processing apparatus 100A and the information processing apparatus 100B, the server 200 responds to the data transmission request transmitted from the information processing apparatus 100A or the information processing apparatus 100B. Data can also be transmitted to the information processing apparatus 100 that transmitted the data transmission request. In the above case, the server 200 plays a role of mediating so-called barter exchange between the information processing apparatus 100A and the information processing apparatus 100B.
