In addition, the information transaction apparatus, the information transaction method, and the information transaction program according to the present application are not limited by this embodiment. In the following embodiments, the same portions are denoted by the same reference numerals, and redundant description is omitted.

[1. Information transaction processing)
First, an example of information transaction processing according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of an information transaction process according to the embodiment. In FIG. 1, information transaction processing will be described by taking the information distribution system 1 as an example.

As shown in FIG. 1, the information distribution system 1 includes provider terminals 10 ₁ to 10 ₃ , a user terminal 20, and an information transaction apparatus 100. The information transaction device 100 is communicably connected to the provider terminals 10 ₁ to 10 ₃ and the user terminal 20 via a network (not shown) (for example, the Internet). Note that the number of provider terminals 10 ₁ to 10 ₃ and user terminals 20 included in the information distribution system 1 is not limited to the example shown in FIG.

Provider terminals 10 ₁ to 10 ₃ are information processing devices used by information providers U ₁ to U ₃ , respectively. The user terminal 20 is an information processing device used by the information user R. The provider terminals 10 ₁ to 10 ₃ and the user terminal 20 are, for example, mobile terminals such as smartphones, tablet terminals and PDAs (Personal Digital Assistants), desktop PCs (Personal Computers), and notebook PCs. In the case of the example of FIG. 1, the provider terminals 10 ₁ to 10 ₃ are assumed to be mobile terminals.

Here, information providers U1-U3 are general users who have a smart phone etc., for example, and profit is provided by providing user information to information user R for a fee. The information user R is, for example, a company or an organization that analyzes user information purchased from the information providers U1 to U3. Hereinafter, when there is no need to distinguish between the information providers U1 to U3, they may be collectively referred to as “information provider U”. Further, in the following, when it is not necessary to distinguish the provider terminals 10 ₁ to 10 ₃ , they may be collectively referred to as “provider terminal 10”.

  The information transaction apparatus 100 is a server apparatus that performs information transaction processing. Specifically, the information transaction apparatus 100 performs transaction processing of user information between the information provider U and the information user R as described below.

  In the example illustrated in FIG. 1, the information transaction apparatus 100 accumulates user information received from the provider terminal 10 in the storage unit 120 as a data asset. Here, the user information is information related to the provider terminal 10 and information related to the information provider U. As will be described in detail later, the user information corresponds to, for example, position information acquired by the provider terminal 10.

  Then, the user terminal 20 transmits a user information acquisition request to the information transaction apparatus 100 in accordance with the operation by the information user R (step S11). In this case, the information transaction apparatus 100 determines whether or not the user information corresponding to the acquisition request is held by searching the storage unit 120 (step S12). If the information transaction apparatus 100 does not hold even part of the user information corresponding to the acquisition request, the information provider that provides the user information so that all user information corresponding to the acquisition request can be collected. U candidates are determined. In other words, the information transaction apparatus 100 determines a candidate for the information provider U in order to acquire user information that is not stored in the storage unit 120 among user information corresponding to the acquisition request. In the following description, “candidate information provider U providing user information” determined by the information transaction apparatus 100 may be referred to as “collection target person”. That is, the information transaction apparatus 100 determines at least one information provider U as a collection target person so that at least user information corresponding to the acquisition request can be collected when user information can be acquired from all collection target persons. To do.

  Then, the information transaction apparatus 100 acquires user information from the collection target person. Specifically, the information transaction apparatus 100 transmits request information including an acquisition condition for insufficient user information to the provider terminal 10 (step S13). As will be described in detail later, the user information acquisition condition indicates, for example, the type of user information, the accuracy of user information, the acquisition frequency of user information, and the like.

  Subsequently, as a response to the request information, the provider terminal 10 transmits consent information indicating whether or not to consent to the provision of user information to the information transaction apparatus 100 according to an operation by the information provider U (step S14).

  Subsequently, when the information transaction apparatus 100 receives consent information indicating consent from the provider terminal 10, an information providing application (an example of an information providing program) that is an application program for acquiring user information is provided. It transmits to the provider terminal 10 (step S15). At this time, the information transaction apparatus 100 transmits to the provider terminal 10 an acquisition application that acquires user information according to the acquisition conditions transmitted in step S13. This acquisition application is installed in the provider terminal 10 to acquire user information (for example, position information) according to the acquisition condition. That is, the provider terminal 10 transmits user information to the information transaction apparatus 100 according to control by the acquisition application (step S16).

  Subsequently, the information transaction apparatus 100 stores the user information received from the provider terminal 10 in the storage unit 120 (step S17). In this way, the information transaction apparatus 100 acquires from the provider terminal 10 user information that is not stored in the storage unit 120 among user information corresponding to the acquisition request.

  Subsequently, the information transaction apparatus 100 refers to the storage unit 120 to determine whether or not all of the user information corresponding to the acquisition request that has not been stored in the storage unit 120 has been acquired. judge. And the information transaction apparatus 100 produces | generates newly acquisition conditions according to the acquisition condition of user information, when not acquiring all the user information (step S18).

  For example, when the information transaction apparatus 100 has a low probability of collecting all user information by the delivery date, which is the date and time when user information is provided to the user terminal 20, many provider terminals 10 receive user information. Relax the acquisition conditions so that they can be collected. In addition, for example, the information transaction apparatus 100 tightens the acquisition conditions when there is a high probability that all user information can be collected before the delivery date. Thus, the information transaction apparatus 100 adjusts the acquisition conditions according to the acquisition status of the user information. Note that the information transaction apparatus 100 may change the acquisition condition only when an approval is obtained from the information user R.

  And the information transaction apparatus 100 performs the process in step S15 and S16, after producing | generating a new acquisition condition in step S18. Here, the information transaction apparatus 100 transmits only new acquisition conditions to the provider terminal 10 in which the information providing application is already installed. Specifically, the information transaction apparatus 100 controls the information providing application to acquire user information according to the new acquisition condition by notifying the information providing application that the acquisition condition has been changed. That is, the information transaction apparatus 100 dynamically controls the behavior of the information providing application according to the acquisition state of the user information.

  In this way, the information transaction apparatus 100 repeats the processes in steps S15 to S18 until all the shortage of user information is acquired. And when all the user information is acquired, the information transaction apparatus 100 provides the user information corresponding to an acquisition request to the user terminal 20 (step S19).

  Although not shown in FIG. 1, after step S <b> 19, the information user R pays a predetermined fee to the administrator of the information transaction apparatus 100 as a user information usage fee. Then, the administrator or the like of the information transaction apparatus 100 sends a part of the usage fee obtained from the user terminal 20 to the information provider U that is the transmission source of the user information provided to the user terminal 20 in step S19 or Pay everything as a reward.

  As described above, the information transaction apparatus 100 according to the embodiment acquires the missing user information from the user terminal 20 when the user information corresponding to the acquisition request received from the user terminal 20 is not held. . For this reason, the information transaction apparatus 100 can provide the information user R with user information desired by the information user R. Furthermore, the information transaction apparatus 100 dynamically adjusts the acquisition conditions for user information acquired from the user terminal 20 according to the acquisition status of user information. For this reason, the information transaction apparatus 100 can increase the accuracy with which user information can be provided to the information user R. That is, the information transaction apparatus 100 can provide a trading service useful for the information user R. As a result, the information transaction apparatus 100 can promote an increase in the number of information users R who use the trading service provided by the information transaction apparatus 100. This increases the number of sales destinations of user information stored in the information transaction apparatus 100. Therefore, the information transaction apparatus 100 promotes an increase in the number of information providers U who make a profit by providing user information. can do. From the above, the information transaction apparatus 100 can activate the distribution of user information.

[2. (Configuration of provider terminal)
Next, the configuration of the provider terminal 10 according to the embodiment will be described using FIG. FIG. 2 is a diagram illustrating a configuration example of the provider terminal 10 according to the embodiment. As shown in FIG. 2, the provider terminal 10 includes a communication unit 11, an input unit 12, a display unit 13, a detection unit 14, a storage unit 15, and a control unit 16.

  The communication unit 11 is connected to a network by wire or wireless, and transmits / receives information to / from the information transaction apparatus 100. For example, the communication unit 11 is realized by a NIC (Network Interface Card) or the like.

  The input unit 12 is an input device that receives various operations from the user. For example, the input unit 12 is realized by a hard key or the like provided on the side wall of the provider terminal 10 or the like. The display unit 13 is a display device for displaying various information. For example, the display unit 13 is realized by a liquid crystal display or the like. In addition, when a touch panel is employ | adopted for the provider terminal 10, a part of input part 12 and the display part 13 are integrated.

  The detection unit 14 detects various information related to the provider terminal 10. Specifically, the detection unit 14 detects the physical state of the provider terminal 10 as user information. In the example illustrated in FIG. 2, the detection unit 14 includes a positioning unit 14a and a pressure sensor 14b.

  The positioning unit 14a acquires the current position of the provider terminal 10. Specifically, the positioning unit 14a receives radio waves transmitted from a GPS (Global Positioning System) satellite, and position information (for example, latitude and longitude) indicating the current position of the provider terminal 10 based on the received radio waves. To get. The pressure sensor 14b detects the atmospheric pressure around the provider terminal 10.

  In addition, the detection part 14 is not restricted to the positioning part 14a and the pressure sensor 14b, You may have various apparatuses which detect the physical state of the provider terminal 10. FIG. For example, the detection unit 14 is a microphone that collects sound around the provider terminal 10, an illuminance sensor that detects illuminance around the provider terminal 10, and an acceleration sensor that detects physical movement of the provider terminal 10. (Or a gyro sensor, etc.), a humidity sensor that detects the humidity around the provider terminal 10, a geomagnetic sensor that detects a magnetic field at the location of the provider terminal 10, and the like. Moreover, the detection part 14 may have a microphone, an illumination intensity sensor, a humidity sensor, a geomagnetic sensor, etc., without having the positioning part 14a and the pressure sensor 14b.

  Further, the detection unit 14 described above may calculate the accuracy in the user information acquisition process. For example, when the positioning unit 14a acquires position information, the positioning unit 14a calculates the accuracy indicating the accuracy of the acquired position information. Such an accuracy calculation function is often mounted on a general sensor.

  The storage unit 15 is realized by, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

  The storage unit 15 stores user information acquisition conditions and user information detected by the detection unit 14. The user information acquisition condition may be transmitted together with the information providing application from the information transaction apparatus 100, or may be updated as needed by the information transaction apparatus 100 after the information providing application is transmitted.

  The control unit 16 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like executing various programs stored in the storage device inside the provider terminal 10 using the RAM as a work area. Is done. Moreover, the control part 16 is implement | achieved by integrated circuits, such as ASIC (Application Specific Integrated Circuit) and FPGA (Field Programmable Gate Array), for example.

  As shown in FIG. 2, the control unit 16 includes a confirmation unit 17 and a provision control unit 18, and realizes or executes information processing functions and operations described below. The internal configuration of the control unit 16 is not limited to the configuration illustrated in FIG. 2, and may be another configuration as long as the information processing described later is performed. In addition, the connection relationship between the processing units included in the control unit 16 is not limited to the connection relationship illustrated in FIG. 2, and may be another connection relationship.

  When the confirmation unit 17 receives the request information from the information transaction apparatus 100, the confirmation unit 17 displays the received request information on the display unit 13, thereby allowing the information provider U to confirm whether or not to agree to the provision of the user information. . And the confirmation part 17 produces | generates the consent information which shows consent, when the operation to the effect of consent is performed by the information provider U, and transmits the produced | generated consent information to the information transaction apparatus 100. FIG. At this time, the confirmation unit 17 transmits a provider identifier for identifying the information provider U or the provider terminal 10 to the information transaction apparatus 100 in addition to the consent information.

  In addition, when the information provider U agrees to provide user information, the confirmation unit 17 may receive an information providing application and user information acquisition conditions from the information transaction apparatus 100. In this case, the confirmation unit 17 stores the acquisition condition received from the information transaction apparatus 100 in the storage unit 15.

  In addition, the confirmation unit 17 may receive only acquisition conditions from the information transaction apparatus 100. For example, when the process of step S18 shown in FIG. 1 is performed by the information transaction apparatus 100, the confirmation unit 17 receives only the acquisition condition. In this case, the confirmation unit 17 updates the acquisition condition stored in the storage unit 15 to the acquisition condition received from the information transaction apparatus 100.

  The provision control unit 18 is realized by, for example, a CPU, an MPU, or the like executing the information provision application received by the confirmation unit 17 using the RAM as a work area. The information providing application may be installed in the provider terminal 10 in advance, or a server apparatus other than the information transaction apparatus 100 (for example, providing various applications) according to an operation by the information provider having the provider terminal 10. It may be installed in the provider terminal 10 by being downloaded from the server device.

  As shown in FIG. 2, the provision control unit 18 includes an acquisition unit 18a and a transmission unit 18b, and realizes or executes the functions and operations of information processing described below.

  The acquisition unit 18a acquires user information. Specifically, the acquisition unit 18 a controls the detection unit 14 in accordance with the acquisition conditions stored in the storage unit 15. Thereby, the acquisition unit 18a acquires various types of information detected by the detection unit 14 as user information and stores the acquired user information in the storage unit 15. At this time, when the accuracy of the user information is calculated by the detection unit 14, the acquisition unit 18 a stores the user information and the accuracy in the storage unit 15 in association with each other.

  For example, when the acquisition condition stored in the storage unit 15 is “acquisition of position information every 10 minutes”, the acquisition unit 18a controls the positioning unit 14a every 10 minutes. Thereby, the acquisition part 18a acquires the positional information which shows the present position of the provider terminal 10 as user information every 10 minutes. Similarly, the acquisition unit 18a acquires atmospheric pressure information indicating the atmospheric pressure around the provider terminal 10 as user information by controlling the pressure sensor 14b according to the acquisition condition.

  In addition, the acquisition unit 18 a is not limited to the above example, and acquires various types of user information from each device according to a device such as a sensor included in the detection unit 14. For example, when the detection unit 14 includes a microphone, the acquisition unit 18a acquires sound collection information indicating the loudness of sound collected by the microphone as user information. Moreover, the acquisition part 18a acquires the illumination intensity information which shows the illumination intensity around the provider terminal 10 as user information, when the detection part 14 has an illumination intensity sensor. Moreover, the acquisition part 18a acquires the inclination information which shows the inclination of the provider terminal 10 as user information, when the detection part 14 has an acceleration sensor. Moreover, the acquisition part 18a acquires the humidity information which shows the humidity around the provider terminal 10 as user information, when the detection part 14 has a humidity sensor. Moreover, the acquisition part 18a acquires the magnetic field information which shows the magnetic field in the location of the provider terminal 10 as user information, when the detection part 14 has a geomagnetic sensor.

  The transmission unit 18b transmits the user information acquired by the acquisition unit 18a to the information transaction apparatus 100. Specifically, the transmission unit 18b acquires user information that the information provider U has agreed to provide from the storage unit 15. And the transmission part 18b transmits the user information acquired from the memory | storage part 15 to the information transaction apparatus 100. FIG. At this time, when the accuracy of the user information is stored in the storage unit 15 in association with the user information, the transmission unit 18b transmits the accuracy to the information transaction apparatus 100 together with the user information. In addition to the user information, the transmission unit 18b transmits a provider identifier, an acquisition date and time when the user information is acquired by the acquisition unit 18a, and the like to the information transaction apparatus 100.

  In the above example, the example in which the provision control unit 18 acquires user information in accordance with the acquisition condition received from the information transaction apparatus 100 is shown. However, depending on the provider terminal 10, user information may be acquired according to the acquisition conditions set by the information provider U or the like, and the acquired user information may be appropriately transmitted to the information transaction apparatus 100. For example, some information providers U may desire to obtain profits by providing user information to the information transaction apparatus 100 regardless of whether the information transaction apparatus 100 requests it. In this case, the information provider U can periodically obtain user information by transmitting user information to the information transaction apparatus 100 and transacting user information with the information user R. However, even in such a provider terminal 10, when the information provider U agrees to the request from the information transaction apparatus 100 and receives the acquisition condition from the information transaction apparatus 100, the acquisition condition of the storage unit 15 Update.

[3. Configuration of information transaction device]
Next, the configuration of the information transaction apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration example of the information transaction apparatus 100 according to the embodiment. As illustrated in FIG. 3, the information transaction apparatus 100 includes a communication unit 110, a transaction history storage unit 121, a user information storage unit 122, and a control unit 130.

  The communication unit 110 is connected to a network by wire or wireless, and transmits and receives information between the provider terminal 10 and the user terminal 20. For example, the communication unit 110 is realized by a NIC or the like.

  The transaction history storage unit 121 and the user information storage unit 122 are realized by a semiconductor memory element such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk, for example. The transaction history storage unit 121 and the user information storage unit 122 correspond to the storage unit 120 illustrated in FIG.

  The transaction history storage unit 121 stores history information regarding user information transactions between the information provider U and the information user R. Here, FIG. 4 shows an example of the transaction history storage unit 121 according to the embodiment. Note that FIG. 4 shows two states in which information stored in the transaction history storage unit 121 is different. Here, description will be made using the upper example. In the example illustrated in FIG. 4, the transaction history storage unit 121 includes “user identifier”, “request date”, “request target”, “acquisition condition (request target)”, “delivery date”, “provider information”, and the like. Have items.

  The “user identifier” indicates identification information for identifying the information user R or the user terminal 20 that has transmitted the user information acquisition request. “Request date and time” indicates the date and time when the information transaction apparatus 100 received an acquisition request from the user terminal 20. “Request target” indicates user information requested by an acquisition request. “Acquisition condition” indicates a condition of user information to be acquired by the provider terminal 10. “Delivery date” indicates the date and time when the information transaction apparatus 100 provides the user information to the user terminal 20.

  The “provider information” indicates various pieces of information related to the information provider U (that is, the collection target person) that is the transmission destination of the request information. In the example of FIG. 4, “provider information” is divided into items such as “provider identifier” and “consent information”. The “provider identifier” indicates identification information for identifying the collection target person or the provider terminal 10 of the collection target person. The “consent information” indicates whether or not the collection target person who received the request report has agreed to provide user information. In FIG. 4, when the consent information is “OK”, it indicates that the collection target person has agreed. Further, when the consent information is “NG”, it indicates that the collection target person does not agree or the consent information is not received from the provider terminal 10.

  Hereinafter, an information provider whose provider identifier is “UX” may be referred to as “information provider UX”. An information user whose user identifier is “RX” may be referred to as “information user RX”.

  For example, in FIG. 4, the information transaction apparatus 100 corresponds to “position information for 100 people acquired in 2013” from the user terminal 20 of the information user R01 on “November 1, 2013”. An example of receiving a user information acquisition request (here, acquisition request X1) is shown. In FIG. 4, the information transaction apparatus 100 provides the request information including the acquisition condition “location information whose accuracy acquired in 2013 is“ 5 ”” corresponding to the acquisition request X1 to the provider terminal of the information provider U01. 10 shows an example in which agreement information indicating agreement is transmitted. On the other hand, FIG. 4 shows an example in which the information transaction apparatus 100 transmits request information to the provider terminal 10 of the information provider U02 and does not receive consent information indicating consent from the provider terminal 10.

  The user information storage unit 122 stores user information provided from the provider terminal 10. Here, FIG. 5 illustrates an example of the user information storage unit 122 according to the embodiment. In the example illustrated in FIG. 5, the user information storage unit 122 includes items such as “acquisition date”, “provider identifier”, and “user information”.

  “Acquisition date / time” indicates the date / time when the user information was acquired. For example, “acquisition date and time” corresponds to the acquisition date and time transmitted together with the user information by the transmission unit 18 b of the provider terminal 10. The “provider identifier” indicates identification information for identifying the provider terminal 10 or the information provider that has transmitted the user information. For example, the “provider identifier” corresponds to the provider identifier transmitted together with the user information by the transmission unit 18 b of the provider terminal 10.

  “User information” indicates user information received from the provider terminal 10. In the case of the example in FIG. 4, “user information” is classified into types such as “position information” and “atmospheric pressure information”. Although not shown in FIG. 5, the “user information” may have types such as “sound collection information”, “illuminance information”, “gradient information”, and “magnetic field information”.

  The user information shown in FIG. 5 is divided into items such as “value”, “accuracy”, and “granularity” for each type. “Value” indicates user information received from the provider terminal 10. “Accuracy” and “granularity” correspond to characteristic information indicating characteristics of user information. Specifically, “accuracy” indicates the accuracy of user information. “Granularity” indicates the level of detail and fineness of user information. The “accuracy” and “granularity” shown in FIG. 5 store evaluation values indicated by five levels “1” to “5”. In this example, the evaluation value “1” indicates the lowest value, and the evaluation value “5” indicates the highest value.

  For example, user information in which a large value is stored in “accuracy” indicates that the detection unit 14 of the provider terminal 10 has been acquired with high accuracy. As described above, the accuracy of user information may be calculated depending on the detection unit 14 of the provider terminal 10. The information transaction apparatus 100 receives the accuracy of such user information from the provider terminal 10 and updates the accuracy of the user information storage unit 122 according to the received accuracy.

  Further, for example, user information in which a large value is stored in “granularity” indicates that the user information itself is detailed. Explaining by taking the position information as an example, depending on the provider terminal 10, as position information, longitude and latitude capable of specifying the position in detail may be transmitted to the information transaction apparatus 100. Depending on the provider terminal 10, only the prefecture may be transmitted to the information transaction apparatus 100 as the position information. Depending on the provider terminal 10, the prefecture and the city may be transmitted to the information transaction apparatus 100 as the position information. The information transaction apparatus 100 updates the granularity of the user information storage unit 122 according to the granularity of such user information itself.

  For example, in FIG. 5, the position information “A01” and the atmospheric pressure information “B01” are acquired by the provider terminal 10 of the information provider U01 at “November 1, 2013, 12:00:00”. Show. For example, FIG. 5 shows an example in which the location information “A02” is acquired by the provider terminal 10 of the information provider U02 at “November 1, 2013, 12:00:00”. As in the two examples given here, the type of user information acquired by the provider terminal 10 is different for each provider terminal 10.

  FIG. 5 shows an example in which conceptual information such as “A01” is stored in “value” of “position information”, but in actuality, “latitude and longitude” or “address ( For example, “prefectures and municipalities” ”and the date and time when these pieces of information are acquired are stored. Actually, a numerical value indicating the atmospheric pressure is stored in the “atmospheric pressure information”.

  Returning to the description of FIG. 3, the control unit 130 uses, for example, a CPU, an MPU, or the like to store a RAM in which various programs (corresponding to an example of the information transaction program) stored in the storage device inside the information transaction apparatus 100 are stored in the RAM This is realized by being executed as The control unit 130 is realized by an integrated circuit such as an ASIC or FPGA, for example.

  As illustrated in FIG. 3, the control unit 130 includes a request reception unit 131, an acquisition unit 132, an acquisition control unit 133, and a provision unit 134, and realizes functions and operations of information processing described below or Run. Note that the internal configuration of the control unit 130 is not limited to the configuration illustrated in FIG. 3, and may be another configuration as long as the information processing described below is performed. Further, the connection relationship between the processing units included in the control unit 130 is not limited to the connection relationship illustrated in FIG. 3, and may be another connection relationship.

  The request receiving unit 131 receives a user information acquisition request from the user terminal 20. Specifically, the request receiving unit 131 receives an acquisition request including a user identifier, a delivery date, and an acquisition condition for user information to be acquired. For example, the request reception unit 131 receives an acquisition request including an acquisition condition for specifying the type of user information. For example, the request reception unit 131 receives an acquisition request including an acquisition condition for specifying a period of acquisition date and time when the user information is acquired. For example, the request reception unit 131 receives an acquisition request including an acquisition condition for specifying the number of information providers U corresponding to user information to be acquired. For example, the request receiving unit 131 has the type of user information “location information”, the acquisition date and time “2013”, and the maximum accuracy of the user information “5”. An acquisition request for requesting user information for 100 people satisfying the above condition is accepted.

  When the request reception unit 131 receives a user information acquisition request, the request reception unit 131 collects user information corresponding to the acquisition request based on the user information stored in the user information storage unit 122. To decide. Specifically, the request receiving unit 131 determines whether or not user information that matches the acquisition condition included in the acquisition request is stored in the user information storage unit 122. Then, if even part of the user information that matches the acquisition condition is insufficient, the request reception unit 131 determines the information provider U necessary for collecting the insufficient user information as the collection target person. . In addition, the request reception part 131 can grasp | ascertain the user information which each provider terminal 10 provided in the past with reference to the user information storage part 122. FIG. That is, since the information transaction apparatus 100 can grasp user information that can be provided by the provider terminal 10 based on the provision results, the information transaction apparatus 100 can easily determine the collection target person.

  Then, the request reception unit 131 stores the user identifier, the acquisition condition, and the delivery date included in the acquisition request in association with the provider identifier of the collection target person in the transaction history storage unit 121. At this time, the request reception unit 131 stores the date and time when the acquisition request is received in the “request date and time” of the transaction history storage unit 121, and sets the condition of user information requested in the acquisition request as “request” of the transaction history storage unit 121. Store in "Target". Further, the request receiving unit 131 determines an acquisition condition for the provider terminal 10 to acquire user information based on the user information stored in the transaction history storage unit 121, and the determined acquisition condition is set to the transaction history storage unit 121. To store. For example, when there is a small amount of user information that is insufficient, the request reception unit 131 stores the acquisition conditions set with high accuracy and granularity in the transaction history storage unit 121, and there is a large amount of user information that is insufficient. In some cases, the acquisition condition in which accuracy and granularity are set low is stored in the transaction history storage unit 121.

  Then, the request reception unit 131 transmits request information including the acquisition conditions stored in the transaction history storage unit 121 to the provider terminal 10 of the collection target person. Then, the request reception unit 131 receives, from the provider terminal 10, consent information indicating whether or not to agree to the provision of user information as a response to the request information. In this case, the request receiving unit 131 stores the consent presence / absence indicated by the received consent information in the transaction history storage unit 121.

  The acquisition unit 132 acquires user information corresponding to the user information acquisition request regarding the information provider U or the provider terminal 10 of the information provider U received from the user terminal 20 of the information user R. Specifically, the acquisition unit 132 provides user information corresponding to the acquisition request received by the request reception unit 131 based on the acquisition conditions and provider information stored in the transaction history storage unit 121. Get from. For example, the acquisition unit 132 acquires user information based on the acquisition condition updated by the acquisition control unit 133. The acquisition unit 132 according to the embodiment acquires the user information corresponding to the acquisition request from the provider terminal 10 by transmitting the acquisition condition to the provider terminal 10.

  The acquisition control unit 133 dynamically controls the acquisition process of the user information in the acquisition unit 132 according to the acquisition status of the user information in the acquisition unit 132. Specifically, the acquisition control unit 133 dynamically updates the acquisition condition transmitted to the provider terminal 10 by the acquisition unit 132 according to the acquisition status in the acquisition unit 132.

  Hereinafter, an example of processing in the acquisition unit 132 and the acquisition control unit 133 will be described. First, the acquisition unit 132 sets an acquisition request whose current date and time is before the delivery date among the acquisition requests stored in the transaction history storage unit 121 as a processing target. And the acquisition part 132 extracts the provider identifier by which the consent information which shows consent in the transaction history memory | storage part 121 is memorize | stored. And the acquisition part 132 transmits an information provision application with respect to the provider terminal 10 corresponding to the extracted provider identifier. At this time, the acquisition unit 132 transmits an information providing application that acquires user information in accordance with the acquisition conditions stored in the transaction history storage unit 121. Thereby, the acquisition part 132 acquires user information from the provider terminal 10 which operate | moves according to control of an information provision application. Then, when acquiring the user information from the provider terminal 10, the acquisition unit 132 stores the acquired user information in the user information storage unit 122. In addition, the acquisition part 132 transmits only the acquisition conditions memorize | stored in the transaction log | history memory | storage part 121 with respect to the provider terminal 10 in which the information provision application is already installed.

  Here, when the accuracy of the user information is received together with the user information from the provider terminal 10, the acquisition unit 132 may determine the quality of the received user information. For example, it is assumed that the acquisition condition stored in the transaction history storage unit 121 includes accuracy. In this case, the acquisition unit 132 determines whether the accuracy received together with the user information from the provider terminal 10 satisfies the accuracy included in the acquisition condition. And the acquisition part 132 does not need to store the user information received from the provider terminal 10 in the user information storage part 122, when the precision of acquisition conditions is not satisfy | filled. Similarly, the acquisition unit 132 may determine whether or not the user information satisfies the granularity of the acquisition condition every time user information is received.

  In addition, the acquisition control unit 133 periodically monitors whether the user information corresponding to the acquisition request can be acquired by referring to the transaction history storage unit 121 and the user information storage unit 122. And the acquisition control part 133 adjusts the acquisition conditions memorize | stored in the transaction history memory | storage part 121 according to the probability which can collect the user information corresponding to an acquisition request. Specifically, the acquisition control unit 133 stores in the transaction history storage unit 121 when the accuracy with which user information can be collected by the delivery date is low or when the accuracy with which user information can be collected earlier than the delivery date is high. Update the acquired acquisition condition. Then, the acquisition control unit 133 controls the acquisition unit 132 to transmit the updated new acquisition condition to the provider terminal 10 after updating the acquisition condition of the transaction history storage unit 121. Thereby, the acquisition part 132 acquires the user information based on the updated acquisition conditions from the provider terminal 10 by notifying the information provision application in the provider terminal 10 of the acquisition conditions updated by the acquisition control part 133. To do.

  This point will be described using the example shown in FIG. Hereinafter, an acquisition request received from the information user R01 is referred to as an acquisition request X11, and an acquisition request received from the information user R02 is referred to as an acquisition request X12. In the example in the upper part of FIG. 4, it is assumed that the acquisition control unit 133 determines that the accuracy with which user information corresponding to the acquisition request X11 can be collected by the delivery date is low. In this case, the acquisition control unit 133 updates the acquisition condition from “accuracy: 5” to “accuracy: 4” as in the example illustrated in the lower part of FIG. As described above, the acquisition control unit 133 can improve the accuracy with which the user information corresponding to the acquisition request X11 can be collected by the delivery date by relaxing the acquisition conditions of the user information.

  In the example in the upper part of FIG. 4, it is assumed that the acquisition control unit 133 determines that the user information corresponding to the acquisition request X12 is highly likely to be collected a predetermined number of days earlier than the delivery date. In this case, the acquisition control unit 133 updates the acquisition condition from “granularity: 4” to “granularity: 5” as in the example illustrated in the lower part of FIG. As described above, the acquisition control unit 133 can acquire high-quality user information by tightening the acquisition condition of the user information, and thus the satisfaction of the information user R can be improved.

  The providing unit 134 provides user information corresponding to the acquisition request to the user terminal 20 that is the transmission source of the acquisition request received by the request receiving unit 131. Specifically, the providing unit 134 acquires user information satisfying the acquisition condition stored in the transaction history storage unit 121 from the user information storage unit 122 and provides the acquired user information to the user terminal 20. At this time, the providing unit 134 may provide not only user information but also a combination of user information and a provider identifier to the user terminal 20. In this case, the providing unit 134 converts the provider identifier, not the provider identifier stored in the user information storage unit 122, into other information, and provides the converted provider identifier to the user terminal 20. Also good.

  Further, when providing the user information to the user terminal 20, the providing unit 134 notifies the user terminal 20 of a user information usage fee. Specifically, the providing unit 134 calculates the price of the user information to be provided to the user terminal 20 based on factor information that affects the value of the user information. For example, the providing unit 134 calculates a higher price for user information with higher accuracy and granularity. In addition, for example, the providing unit 134 determines that the user information stored in the user information storage unit 122 has less scarce user information, and calculates higher price as the scarce user information. Then, the providing unit 134 notifies the user terminal 20 of the price of the user information calculated in this way as a usage fee. Further, the providing unit 134 notifies the provider terminal 10 that is the transmission source of the user information provided to the user terminal 20 of the amount of consideration for providing the user information. Specifically, the providing unit 134 notifies a price corresponding to a part or all of the usage fee notified to the user terminal 20 as a reward amount.

  Note that the information transaction apparatus 100 may calculate the price of the user information at the time when the user information acquisition request is received from the user terminal 20 and notify the user terminal 20 of the calculated user information usage fee. . And the information transaction apparatus 100 may start the acquisition process of user information, when the reply to the effect of accepting payment of this usage fee is received from the user terminal 20.

[4. (Information transaction processing procedure)
Next, the procedure of the information transaction process by the information transaction apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing an information transaction processing procedure by the information transaction apparatus 100 according to the embodiment.

  As illustrated in FIG. 6, the information transaction apparatus 100 determines whether a user information acquisition request has been received from the user terminal 20 (step S <b> 101). And the information transaction apparatus 100 waits until an acquisition request is received, when the acquisition request is not received (step S101; No).

  On the other hand, when the information transaction apparatus 100 receives the acquisition request (step S101; Yes), the information transaction apparatus 100 determines the collection target person by referring to the transaction history storage unit 121 and the user information storage unit 122 (step S102). .

  Subsequently, the information transaction apparatus 100 generates an acquisition condition to be transmitted to the collection target person determined in step S102 (step S103). Here, the information transaction apparatus 100 uses the acquisition condition included in the acquisition request.

  Subsequently, the information transaction apparatus 100 transmits request information including acquisition conditions and the like to the provider terminal 10 of the collection target person (step S104). Subsequently, after transmitting the request information, the information transaction apparatus 100 determines whether or not the consent information is received from the provider terminal 10 (step S105). And the information transaction apparatus 100 waits until consent information is received, when consent information is not received (step S105; No).

  On the other hand, when the information transaction apparatus 100 receives the consent information (step S105; Yes), the information providing application together with the acquisition condition generated in step S103 is sent to the provider terminal 10 that has transmitted the consent information indicating consent. Is transmitted (step S106). Thereby, the information transaction apparatus 100 acquires user information from the provider terminal 10 (step S107).

  Subsequently, the information transaction apparatus 100 determines whether or not all user information corresponding to the acquisition request received in step S101 has been acquired (step S108). And when all the user information is not acquired (step S108; No), the information transaction apparatus 100 determines whether adjustment of acquisition conditions is required (step S109). For example, the information transaction apparatus 100 determines that the acquisition condition needs to be adjusted when the accuracy with which user information can be collected by the delivery date is low or when the accuracy with which user information can be collected more than a predetermined number of days earlier than the delivery date is high.

  And when it determines with the information transaction apparatus 100 requiring adjustment of acquisition conditions (step S109; Yes), user information is provided from the provider terminal 10 based on the new acquisition conditions according to the acquisition condition of user information. It acquires (step S110) and returns to the process in step S108. On the other hand, if the information transaction apparatus 100 determines that the adjustment of the acquisition condition is not required (step S109; No), the information transaction apparatus 100 returns to the process in step S108 without calculating a new acquisition condition.

  Moreover, when all the user information corresponding to an acquisition request is acquired, the information transaction apparatus 100 (step S108; Yes) with respect to the user terminal 20 which is the transmission source of the acquisition request received in step S101, User information corresponding to the acquisition request is provided (step S111).

[5. (Modification)
Each embodiment mentioned above may be implemented with various different forms other than the above-mentioned embodiment. Accordingly, other embodiments will be described below.

[5-1. (Acquisition conditions)
In the above-described embodiment, the acquisition conditions have been described by taking the accuracy of user information, the granularity of user information, the delivery date for providing user information to the user terminal 20 as examples. That is, in the above-described embodiment, an example in which the acquisition control unit 133 adjusts accuracy, granularity, delivery date, and the like according to the acquisition status of user information by the acquisition unit 132 has been described. However, the acquisition control unit 133 may adjust information other than the above example.

  Specifically, the acquisition control unit 133 may change the acquisition frequency indicating the time interval at which the provider terminal 10 acquires the user information according to the acquisition state of the user information by the acquisition unit 132.

  Further, the acquisition control unit 133 may change the collection target person according to the acquisition state of the user information by the acquisition unit 132. For example, the acquisition control unit 133 may increase the number of persons to be collected when the probability that user information can be collected by the delivery date is low. At this time, the acquisition control unit 133 collects the information provider U that holds the user information corresponding to the acquisition request as in the collection target person determination process performed by the request reception unit 131 when the acquisition request is received. As a person.

  Further, depending on the provider terminal 10, the user information that matches the acquisition condition may not be provided to the information transaction apparatus 100 even though the consent information indicating consent is transmitted. In this case, the acquisition control unit 133 may exclude the provider terminal 10 that does not provide user information that matches the acquisition condition from the collection target person, and may set the new information provider U as the collection target person.

  In addition, the acquisition control unit 133 may control the provider terminal 10 to interrupt or resume the user information acquisition process according to the acquisition state of the user information by the acquisition unit 132. Specifically, the acquisition control unit 133 generates an acquisition condition indicating that the user information acquisition process is interrupted and an acquisition condition indicating that the user information acquisition process is resumed. As a result, the acquisition control unit 133 dynamically controls the acquisition process of user information in the acquisition unit 132 as a result. For example, if there is a high probability that the user information can be collected by the delivery date, the acquisition control unit 133 can collect the user information, and the information providing application installed in some of the provider terminals 10 Control to interrupt the user information acquisition process. After that, when the probability that user information can be collected by the delivery date becomes low, the acquisition control unit 133 controls the information providing application to resume the user information acquisition process.

  Further, the acquisition control unit 133 may change the type of user information to be acquired by each collection target person according to the acquisition status of the user information by the acquisition unit 132. For example, the type of user information that can be acquired with high accuracy may differ depending on the provider terminal 10. In this case, the acquisition control unit 133 determines the type of user information that each provider terminal 10 can acquire with high accuracy based on the acquisition result of the user information by the acquisition unit 132. Then, the acquisition control unit 133 dynamically changes the type of user information to be acquired by each provider terminal 10 so that the user information can be acquired with high accuracy. Thereby, the information transaction apparatus 100 can collect highly accurate user information efficiently.

  Moreover, the acquisition control unit 133 may generate more detailed acquisition conditions. For example, the acquisition request transmitted from the user terminal 20 may specify a region from which user information is acquired, such as “location information in region E” or “barometric information in region E”. In this case, the acquisition control unit 133 may generate an acquisition condition including a region where user information is acquired.

[5-2. (Consent information)
Moreover, in the said embodiment, when the provider terminal 10 agrees with provision of user information like the example shown to step S13 and S14 of FIG. 1, the example which the information transaction apparatus 100 transmits an information provision application is shown. Indicated. However, the information transaction apparatus 100 may receive the consent information from the provider terminal 10 in advance. In this case, the information transaction apparatus 100 transmits the information providing application to the provider terminal 10 that has already transmitted the consent information indicating consent without performing the process in step S13 of FIG.

  In the above embodiment, the consent information indicates whether or not the user information is agreed to be provided. However, the consent information may be in an arbitrary format. For example, the information transaction apparatus 100 may receive consent information indicating that the user information is provided and the acquisition condition is changed from the provider terminal 10. In this case, the information transaction apparatus 100 dynamically changes the acquisition condition in the information providing application of the provider terminal 10 as in the processing described above. For example, the information transaction apparatus 100 may accept consent information indicating that the user information is provided but not agreed to change the acquisition condition from the provider terminal 10. In this case, when it is necessary to change the acquisition condition, the information transaction apparatus 100 notifies the new acquisition condition from the provider terminal 10, for example. And the information transaction apparatus 100 changes a new acquisition condition, when the consent information which shows consenting to the change to a new acquisition condition is received from the provider terminal 10. FIG.

  Moreover, in the said embodiment, the example which provides the user information stored in the user information storage part 122 to the user terminal 20 unconditionally was shown. However, before providing user information to the user terminal 20, the information transaction apparatus 100 may inquire whether or not to agree to provide user information from each information provider U corresponding to the user information. . In this case, the information transaction apparatus 100 may receive consent information from the provider terminal 10 in advance. For example, the information transaction apparatus 100 receives the agreement information from the provider terminal 10 when the provider terminal 10 is determined to use the information transaction apparatus 100. In this case, the information transaction apparatus 100 provides the user information corresponding to the provider terminal 10 to the user terminal 20 based on the consent information received in advance. Furthermore, the consent information that the information transaction apparatus 100 receives in advance may be in an arbitrary format. For example, the information transaction apparatus 100 receives from the provider terminal 10 consent information indicating that the provision of user information to the user terminal 20 is permitted unconditionally. In this case, the information transaction apparatus 100 provides user information corresponding to the provider terminal 10 to the user terminal 20 unconditionally. For example, the information transaction apparatus 100 receives consent information including the type of user information permitted to be provided to the user terminal 20 from the provider terminal 10. In this case, the information transaction apparatus 100 provides only the user information corresponding to the type included in the consent information to the user terminal 20. Further, for example, the information transaction apparatus 100 receives from the provider terminal 10 consent information including the business type of the information user R serving as the user information providing destination. In this case, the information transaction apparatus 100 holds in advance a business type for each information user R, or accepts a business type of the information user R from the user terminal 20 together with an acquisition request for user information. When the business type included in the consent information matches the business type of the information user R, the information transaction apparatus 100 sends the user information corresponding to the provider terminal 10 that transmitted the consent information to the user terminal 20. provide.

[5-3. Change acquisition conditions)
Further, when it is determined that it is difficult to collect user information corresponding to the acquisition request received from the user terminal 20, the information transaction apparatus 100 notifies the user terminal 20 of an acquisition condition change request. May be. This point will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of information transaction processing according to the modification.

  Steps S21 to S28 shown in FIG. 7 are the same as steps S11 to S18 shown in FIG. In the example of FIG. 7, the information transaction apparatus 100 determines that it is difficult to collect user information corresponding to an acquisition request as a result of acquiring user information while adjusting acquisition conditions. In this case, the information transaction apparatus 100 notifies the user terminal 20 of an acquisition condition change request (step S29).

  Then, the user terminal 20 transmits a new acquisition request to the information transaction apparatus 100 in accordance with the operation by the information user R (step S30). Thereby, the information user R can reconsider the acquisition conditions. For example, the user terminal 20 can extend the delivery date or reduce the required number of user information.

  And the information transaction apparatus 100 repeats the process in step S22-S28 according to a new acquisition request. And the information transaction apparatus 100 provides the user information corresponding to a new acquisition request to the user terminal 20 (step S31). In this way, the information transaction apparatus 100 may prompt the information user R to reconsider the acquisition conditions.

  In addition, the information transaction apparatus 100 may notify in step S29 when the probability that user information can be collected more than a predetermined number of days earlier than the delivery date is high. Thereby, the information user R can shorten a delivery date or can increase the required number of user information.

[5-4. (Presentation of compensation amount)
Moreover, in the said embodiment, the information transaction apparatus 100 showed the example which transmits the request information containing acquisition conditions to the provider terminal 10 (step S13 of FIG. 1). However, the information transaction apparatus 100 may transmit request information including not only the acquisition conditions but also information on the amount of reward to the provider terminal 10. Thereby, the information provider U can determine whether to provide user information based on the amount of reward.

  Moreover, in the above example, the information transaction apparatus 100 may change the reward amount together with the acquisition condition according to the acquisition state of the user information. For example, when the probability that user information can be collected by the delivery date is low, the information transaction apparatus 100 transmits request information including information on a reward amount higher than the initial reward amount to the provider terminal 10, thereby enabling the user The number of information providers U who agree to provide information may be increased.

  Further, the user terminal 20 may transmit an acquisition request including a budget to the information transaction apparatus 100. In this case, the information transaction apparatus 100 determines the reward amount of the user information based on the budget included in the acquisition request. Further, as in the example shown in FIG. 7, the information transaction apparatus 100 requests not only to change the acquisition condition but also to change the budget when notifying the user terminal 20 of the acquisition condition change request. May be. At this time, the information transaction apparatus 100 determines the remuneration amount of the user information by linear programming or the like according to the user information requested in the acquisition request, the delivery date, the current user information acquisition status, and the budget. An optimal solution can be obtained. Moreover, the information transaction apparatus 100 can obtain | require the parameter | index which shows which of delivery date, a reward amount, and a budget should be changed by using an optimization problem. The information transaction apparatus 100 may notify the user terminal 20 of a change request such as an acquisition condition, a delivery date, and a budget together with such an index.

[5-5. Meta information)
Moreover, in the said embodiment, the information transaction apparatus 100 showed the example which determines a collection target person based on the provision track record of user information. However, the information transaction apparatus 100 may hold meta information indicating what user information each provider terminal 10 has acquired. For example, the information transaction apparatus 100 includes, for each provider terminal 10, meta information including the type of user information that can be acquired at the provider terminal 10, an acquisition period for acquiring user information, an acquisition frequency for acquiring user information, and the like. May be held. Then, the information transaction apparatus 100 may determine the collection target person based on the meta information. In addition, the information transaction apparatus 100 receives meta information from the provider terminal 10, for example, when the provider terminal 10 is determined to use the information transaction apparatus 100.

  Moreover, in the said embodiment, the information transaction apparatus 100 showed the example holding the user information storage part 122. FIG. However, the information transaction apparatus 100 may collect user information from the provider terminal 10 each time an acquisition request is received from the user terminal 20 without accumulating user information. In this case, it is desirable that the information transaction apparatus 100 determines the collection target person who is the acquisition target of the user information by referring to the meta information described above.

[5-6. (User information acquisition processing)
In the said embodiment, the information transaction apparatus 100 showed the example which acquires the user information based on an acquisition condition from an information provision application by transmitting an acquisition condition to the information provision application installed in the provider terminal 10. FIG. However, the information transaction apparatus 100 is not limited to this example, and the information transaction apparatus 100 holds the user information that matches the acquisition condition based on, for example, the provision results of the user information stored in the user information storage unit 122 and the meta information described above. The provider terminal 10 to be identified may be identified, and the identified provider terminal 10 may be requested to provide user information that matches the acquisition conditions. In this case, the provider terminal 10 provides the information transaction apparatus 100 with user information that matches the acquisition condition when the information provider U performs an operation to provide user information.

[5-7. (Collection target)
Moreover, in the said embodiment, the information transaction apparatus 100 accumulate | stores the consent information received from the provider terminal 10 in the past, and each information provider U agrees with provision of user information based on the accumulated consent information. May be obtained (hereinafter, sometimes referred to as consent probability). And the information transaction apparatus 100 is good also considering the information provider U with a high consent probability as a collection object person. Thereby, the information transaction apparatus 100 can acquire user information efficiently from the information provider U with a high probability of consenting.

[5-8. (Change of delivery destination)
Moreover, in the said embodiment, the information transaction apparatus 100 may provide the service from which the information provider U can change the provision destination of user information. Specifically, the information transaction apparatus 100 provides user information for another information user R to an information provider U (that is, the provider terminal 10) who has agreed to provide user information for a predetermined information user R. Request information indicating whether or not to agree with the provision of the request may be transmitted. And the information transaction apparatus 100 may make the information provider U determine whether to change the provision destination of user information. At this time, the information transaction apparatus 100 may transmit request information including information on user information requested by the information user R as the change destination to the provider terminal 10. For example, the information transaction apparatus 100 provides the request information including information indicating that the delivery date is shorter than that of providing user information to the information user R who currently agrees, and that the remuneration amount is high. You may transmit to the terminal 10. Thereby, the information provider U can determine whether or not to change the provision destination of the user information based on the delivery date and the reward amount. For example, it is assumed that the provider terminal 10 is collecting location information based on an acquisition condition such as “location information acquired with accuracy“ 1 ”for one year”. In addition, it is assumed that the information transaction apparatus 100 calculates 3000 yen as a reward amount of user information based on the acquisition condition. Then, while the provider terminal 10 is collecting the location information, the information transaction apparatus 100 determines that the acquisition condition is “location information acquired with accuracy“ 5 ”for one year” from another information user R ”. Assume that a certain acquisition request is received and 5000 yen is calculated as the reward amount of this user information. In this case, the information transaction apparatus 100 transmits to the provider terminal 10 request information including information such as “if the position information is acquired with accuracy“ 5 ”, the reward amount is 5000 yen”. Then, according to the operation by the information provider U, the provider terminal 10 agrees with the newly received request information and transmits consent information indicating that the user information provision destination is changed to the information transaction apparatus 100. Further, in this example, the provider terminal 10 may notify the information transaction apparatus 100 of the accuracy of user information and the like when first transmitting consent information to the information transaction apparatus 100. That is, the provider terminal 10 may notify in advance that there is a possibility that the reward amount or the like may be changed to a new provision destination that is a favorable condition.

[5-9. Reminder)
Moreover, in the said embodiment, although the information transaction apparatus 100 provided the information provision application, you may notify the provider terminal 10 which does not provide user information to provide user information. In addition, the information transaction apparatus 100 restricts the use of the information transaction apparatus 100 to the information provider U of the provider terminal 10 that does not provide the user information even though the information transaction apparatus 100 has notified the user information to be provided. Also good.

[5-10. Processing)
Further, the information transaction apparatus 100 described above may provide the user terminal 20 after processing the user information, instead of providing the user information itself. For example, the information transaction apparatus 100 may obtain the population distribution for each region based on the location information, or may obtain the noise distribution for each region based on the location information and the sound collection information. Or the like may be provided to the user terminal 20. Moreover, when providing the user information after processing to the user terminal 20, the information transaction apparatus 100 may calculate the selling price of the user information as a premium.

[5-11. User information)
In the above-described embodiment, the position information, the atmospheric pressure information, the sound collection information, the illuminance information, the gradient information, and the like have been described as examples of the user information.
