Description

  The present invention relates to a technique for transmitting or receiving content using a computer.

  One purpose of content distribution is to direct a user to a desired location, for example, as part of a marketing activity. For marketing, for example, the technique of Patent Document 1 is known.

Japanese Patent No. 5313091

  As one method of guiding a user to a desired store, a method of distributing coupons usable at the store to the user is known. For example, the user downloads a coupon from the server to the user's mobile terminal and goes to the store for the purpose of receiving the service described in the coupon. The user can receive the service described in the coupon by, for example, showing the display screen of the coupon to a store clerk.

  Generally, it is considered that a user near the store is easier to guide to the store than a user far from the store. As a method for the server to know whether or not the user is near the store, the server uses the mobile terminal's position data (for example, the latitude and longitude detected by the position detection unit of the mobile terminal) from the user's mobile terminal. A method is conceivable in which the determination is based on the distance between the user position represented by the latitude and longitude data and the store position. The position detection unit of the mobile terminal is a device (module) that receives a GPS signal emitted from a GPS (Global Positioning System) satellite and detects the current position based on the GPS signal, for example.

  However, if the location data from the mobile terminal to the server is eavesdropped, the location of the user of the mobile terminal will be known to the eavesdropper. For this reason, there exists a possibility that a user's residence may be known to an eavesdropper.

  This type of problem is not limited to the case where the user's destination is a store, and the case where the user-guided content that is digital content for guiding the user to a defined place is a coupon.

  This type of problem is not limited to the case where the content to be distributed is user-guided content such as a coupon. That is, this type of problem is not limited to the case where the purpose of content distribution guides the user to a defined place.

  Furthermore, this type of problem is not limited to the case where the determination material data (data used by the server for determining content distribution) transmitted from the mobile terminal to the server is position data. For example, when the target detected by the mobile terminal is a time expressed in year / month / day / hour / minute / second, the time data representing the time is transmitted from the mobile terminal to the server, but the time data is wiretapped. In this case, since the time data is generally associated with other types of data such as position data, the eavesdropper knows at what time the position specified from the other type of data is. It will be. Further, the determination material data may include other data instead of or in addition to at least one of the position data and the time data. The determination material data may include data related to the attributes of the user of the mobile terminal. Therefore, if the determination material data is wiretapped, the user may be identified as an eavesdropper.

  An object of the present invention is to realize secure content transmission / reception.

  The application executed on the user terminal having the situation detection unit is metadata of information set by the supplier providing the product or service, and is metadata stored in the user terminal including a combination of the condition and the ID The ID management metadata is referred to using at least one of the detected situation and information input to the user terminal, and if the satisfied condition is in the ID management metadata, the ID management metadata is satisfied. A condition matching ID that is an ID corresponding to a certain condition is transmitted to the server. The server receives the condition conformance ID, and transmits the content corresponding to the condition conformance ID among the plurality of contents to the application. As the “situation” mentioned here, various objects such as time (for example, year / month / day / hour / minute / second) and position (for example, latitude / longitude) can be adopted. The “content” here may be user-guided content (for example, a coupon) for guiding the user to a defined place, or may be content other than the user-guided content. For example, in the case where the content is an advertisement, the advertisement may be non-user-guided content that includes information on the provision timing of the advertisement target (product or service) and does not include information on the provision location, or at least the provision of the advertisement target It may be user-guided content including a place.

  FIG. 1 shows an overview of a system according to an embodiment.

  A computer (hereinafter referred to as a supplier computer) 1 used by a supplier (typically a company) that provides goods or services at a store has a coupon (electronic coupon), and an ID and a condition associated with the coupon. The combination is registered in the server 2. A coupon is a coupon which can be used in a predetermined store, for example. Moreover, since ID is linked | related with a coupon, it is possible to identify a coupon uniquely using ID. Conditions are also associated with coupons and typically correspond to coupon distribution conditions. The coupon distribution condition is defined by one or more condition elements among a plurality of condition elements (for example, the user's position range, sex, moving speed, age, type of credit card possessed, etc.). At least a part of the information registered by the supplier is transmitted to and stored in the user terminal 3 as metadata (hereinafter, ID management metadata) 322. Therefore, the ID management metadata 322 stored in the user terminal 3 is not data defined from the user viewpoint but data defined from the supplier viewpoint.

  The user terminal 3 possessed by the user is a portable (mobile type) information processing terminal collectively referred to as a smart device, and is a smartphone in this embodiment. A smartphone is a type of smart device. A smart device is a multifunctional device that can be used not only for calculation processing but also for a wide variety of applications. Typically, a smart device such as an iPhone (registered trademark) and an iPad (registered trademark) are used. Tablet PC (Personal Computer), including a wearable information processing terminal. Of course, the user terminal 3 may be a smart device other than a smartphone, a smart device that is not a smart device, a mobile phone that does not belong to the category of smart devices, or another mobile information processing terminal.

  The coupon management application 321 is stored in the storage device 32 of the user terminal 3 and executed. Further, the storage device 32 of the user terminal 3 stores the ID management metadata 322 as described above. As described above, the ID management metadata 322 is data defined from the supplier's viewpoint, and includes a combination of an ID and a condition associated with a coupon. The coupon management application 321 receives the ID management metadata 322 from the server 2 and stores the received ID management metadata 322 in the storage device 32.

  Among the situations detected by the coupon management application 321 by the situation detector 39 of the user terminal 3 (at least one of the situation inside and outside the user terminal 3) and the information input to the storage device 32 of the user terminal 3 The ID management metadata 322 is referred to using at least one of the following. The situation detection unit 39 includes, for example, one or more sensors, specifically, for example, a position sensor, an illuminance sensor, an inclination sensor, an acceleration sensor, a magnetic sensor, a proximity sensor, a temperature sensor, a gyro sensor, a pressure sensor, and an atmospheric temperature sensor. In addition, one or more of a humidity sensor, a rotation trajectory sensor, and a gravitational acceleration sensor are included, and the detected condition is a detection result of the one or more sensors. The situation detection unit 39 includes a timer that measures time. The information input to the storage device 32 of the user terminal 3 may be, for example, information input manually to the user terminal 3, or as illustrated in FIG. 1, the other application group 34 (other than the coupon management application 321). It may be information acquired from one or more other predetermined applications. If the satisfied condition is in the ID management metadata 322, the coupon management application 321 transmits a condition matching ID, which is an ID corresponding to the satisfied condition, to the server 2. For example, the above position sensor is a sensor that detects a position by receiving a GPS signal emitted from a GPS (Global Positioning System) satellite, and the detected position is expressed using latitude and longitude. However, the position sensor is not limited to this, and may be any position detection means such as a means for detecting a position by communicating with a base station of a mobile terminal or Wi-Fi (Wireless Fidelity). The data representing the position is not limited to the latitude / longitude data, and may be position data expressed by the employed position detecting means.

  The server 2 receives the condition matching ID from the user terminal 3, and transmits the coupon 323 associated with the condition matching ID among the plurality of coupons to the user terminal 3. The coupon management application 321 of the user terminal 3 receives the coupon 323 from the server 2 and stores the received coupon 323 in the storage device 32. The coupon management application 321 displays the coupon 323. The user can go to a store that can use the coupon 323 by looking at the display screen of the coupon 323.

  FIG. 2 illustrates a system configuration according to the embodiment.

  A plurality of supplier computers 1 and a plurality of user terminals 3 communicate with the server 2 via a communication network (for example, the Internet) 4.

  The supplier computer 1 includes a communication interface device (I / F) 14 for communicating via the communication network 4, a storage device 12, a display device 13, an input device (for example, a keyboard and a pointing device) 15, A CPU (Central Processing Unit) 11 is connected.

  The server 2 includes a communication interface device (I / F) 24 for communicating via the communication network 4, a storage device 22, and a CPU 21 connected thereto.

  As described above, the user terminal 3 is, for example, a smartphone, and includes a touch panel 33, a storage device 32, a communication interface device (I / F) 34 for communicating via the communication network 4, a situation detection unit 39, CPU 31 connected to them. Instead of the touch panel 33, an input device and a display device may exist separately. The situation detection unit 39 is a mechanism that detects the situation of the user terminal 3, and includes a timer and one or more sensors as described above.

  FIG. 3 shows a program stored in the storage device 12 of the supplier computer 1.

  For example, a Web browser 121 is stored in the storage device 12 as a program executed by the CPU 11. The supplier can register a coupon and an ID / condition combination (a combination of an ID and a condition) associated with the coupon in the server 2 via the Web browser 121.

  FIG. 4 shows data and programs stored in the storage device 22 of the server 2.

  For example, a coupon management database (DB) 223 and an area ID management DB 224 are stored in the storage device 22 as data. The DBs 223 and 224 may be stored in an external storage device (not shown) of the server 2. Further, the storage device 22 stores, for example, a coupon registration program 221 and a coupon provision program 223 as programs to be executed by the CPU 21.

  The coupon management DB 223 includes information representing a coupon and an ID / condition combination for each coupon. The area ID management DB 224 includes one or more IDs (IDs associated with coupons) for each area ID. The server 2 can receive the area ID from the user terminal 3 and transmit ID management metadata of the ID to the user terminal 3 for the received area ID. That is, not all information registered in the coupon management DB 223 but only the coupon ID management metadata associated with the area to which the position of the user terminal 3 belongs can be transmitted to the user terminal 3, and the user terminal 3 The ID management metadata is stored. A DB may exist for each supplier, and DBs 223 and 224 corresponding to the supplier may be included in the DB of each supplier.

  The coupon registration program 221 receives a coupon and ID / condition combination from the supplier computer 1 and registers them in the coupon management DB 223. The coupon providing program 223 receives an ID from the user terminal 3, acquires a coupon corresponding to the ID from the coupon management DB 223, and provides the coupon to the user terminal 3.

  FIG. 5 shows data and programs stored in the storage device 32 of the user terminal 3.

  In the storage device 32, for example, ID management metadata 322, a coupon 323, an area table 324, and a user behavior table 325 are stored as data. The storage device 32 stores, for example, a coupon management application 321 as a program executed by the CPU 31.

  The ID management metadata 322 has a combination of an ID and a condition. The coupon 323 is an electronic coupon distributed (downloaded) from the server 2. The coupon 323 includes information (name, address, etc.) regarding a store where the coupon 323 can be used, information indicating a service that can be received, a validity period, and the like. The area table 324 has an area ID and area information (information defining an area range) for each area. The user behavior table 325 is information related to the user's behavior and represents the detection result by the situation detection unit 39 (for example, a position obtained from the situation detection unit 39, an estimated movement state (for example, a state specified based on an acceleration sensor), And time). The user behavior table 325 includes, for example, user situation information and an identification code for specifying the information. The identification code may include information representing the detection time of the user situation information associated with the identification code. By including the information representing the detection time, the identification code serves as a log of the user situation information, and each user situation information is By uniquely specifying, the user status information can be matched with other information. For example, based on one of information (for example, time) represented by time information in information obtained by other than the situation detection unit 39 and information (for example, detection time) in an identification code associated with user situation information. In addition, information associated with the other can be identified.

  The coupon management application 321 is an application program executed on the user terminal 3, and may be installed from the server 2, a server of another institution, a portable storage medium, or the like. The coupon management application 321 periodically acquires the detection result of the situation detection unit 39 and registers information (for example, user situation information and detection time) indicating the acquired detection result in the user behavior table 325. The coupon management application 321 acquires an ID corresponding to a condition satisfied by at least one of the detection result and information input to the user terminal 3 from the ID management metadata 322, and transmits the acquired ID to the server 2. To do. Then, the coupon management application 321 receives the coupon 323 corresponding to the ID from the server 2 and stores the coupon 323 in the storage device 32. Note that the process of registering the user status information and the detection time in the user behavior table 325 may be performed by an application program different from the coupon management application 321 or an OS (operating system) of the user terminal 3. Moreover, the coupon management application 321 estimates a user's action by the coupon management application 321 from the history of the detection time and the user situation information represented by the user action table 325, and transmits the area ID according to the estimated action. It is possible to control whether or not. Instead of or in addition to the user behavior table 325, the user behavior may be estimated from user schedule data managed by the user terminal 3 (for example, data in which a calendar and a user's schedule are recorded).

  Hereinafter, data in the server 2 and the user terminal 3 will be described. First, the DBs 223 and 224 managed by the server 2 will be described.

  FIG. 6 shows the configuration of the coupon management DB 223.

  The coupon management DB 223 has a record for each coupon, and each record has an ID 701 that is an ID associated with the coupon, a condition 703 that is information representing a condition associated with the coupon, and a coupon that is transmitted to the user terminal. And a coupon 702 which is information including information constituting the H.323. The condition 703 includes a plurality of condition elements and a rule defined by one or more condition elements selected from the plurality of condition elements. With this configuration, once the supplier has defined a plurality of condition elements, the supplier can edit the conditions associated with the coupon simply by editing the rule (combination of condition elements). The plurality of condition elements may be, for example, the area where the user is, the gender of the user, the moving speed of the user, the type of credit card possessed by the user, and the like. The area registered in the coupon management DB 223 may be an area ID, or an area range expressed in latitude and longitude (for example, the latitude and longitude and radius of the center position).

  FIG. 7 shows the configuration of the area ID management DB 224.

  The area ID management DB 224 has a record for each area, and each record has an area ID 602 that is an ID of the area and one or more IDs 603 corresponding to one or more coupons associated with the area.

  Next, the tables 324, 322, and 325 stored in the user terminal 3 will be described.

  FIG. 8 shows the configuration of the area table 324.

  The area table 324 is a kind of metadata and may be stored in advance in the storage device 32 of the user terminal 3. The area includes a plurality of sub areas, and the plurality of sub areas may be grouped. An area can be used as a sub-area group in which a plurality of sub-areas are grouped according to usage frequency for each supplier. Alternatively, an area in which a plurality of suppliers bundles a plurality of sub-areas can be shared. The area table 324 may exist for each supplier, but in this embodiment, the area table 324 is a table common to all suppliers. The area table 324 has a record for each area, and each record has an area ID 801 that is an area ID and an area range 802 that is information defining the area range. The area range 802 may be information using latitude and longitude values, or may be described in a predetermined unit such as a prefecture. The area where the user terminal 3 exists can be detected based on the address detected based on the latitude and longitude detected by the situation detection unit 39 and the map information (not shown) of the user terminal 3. Good.

  FIG. 9 shows the configuration of the ID management metadata 322.

  The ID management metadata 322 is a table distributed from the server 2 and corresponds to a part of the area ID management DB 224, specifically, the area ID transmitted from the user terminal 3 to the server 2 in the coupon management DB 223. This is the part associated with the ID. Therefore, the ID management metadata 322 has a combination (record) of the ID 902 and the condition 903. The ID 902 and the condition 903 are the same as the ID 701 and the condition 703 shown in FIG.

  FIG. 10 shows the configuration of the user behavior table 325.

  The user behavior table 325 has a record for each time when the position or the like of the user terminal 3 is detected, and each record has a detection time 1001 that represents the time, and a detection position 1002 that represents the detected position of the user terminal 3. And a sensor value 1003 representing user situation information from sensors other than the position sensor in the situation detection unit 39. The user behavior table 325 is updated regularly or irregularly by the coupon management application 321 (or another program).

  Hereinafter, the processing flow performed in the present embodiment will be described.

  FIG. 11 shows an overall processing flow in the embodiment.

  Coupon registration is performed (S1101). Specifically, for example, the Web browser 121 executed by the supplier computer 1 accesses the server 2, and the supplier requests the server 2 for coupon registration via the Web browser 121. Upon receiving the registration, the coupon registration program 221 of the server 2 displays a coupon registration screen 1200 as shown in FIG. The coupon registration screen 1200 includes an area registration area 1201, a coupon registration area 1202, an ID input field 1203, a condition input field 1204, and a registration button 1205. In the area registration area 1201, the supplier designates a circle with a radius desired by the supplier centered on the location of the user guidance destination store as a delivery range (area as one condition element) (the delivery range does not necessarily include the user guidance destination). Not necessarily). In addition, the supplier inputs a coupon (for example, information such as the name of a store that can be used, the contents of a service, and a validity period) in the coupon registration area 1202. Further, the supplier inputs an ID to be associated with the coupon in the ID input field 1203, and inputs a condition (a plurality of condition elements and a rule (a combination of one or more of the plurality of condition elements) in the condition input field 1204). The area registration area 1201 does not necessarily have to be used, in which case the area as one condition element is expressed by an area ID, etc. The supplier associates the input ID and condition with the input coupon. When registering, the user presses a registration button 1205. The supplier performs these operations using the input device 15 while viewing the coupon registration screen 1200 displayed on the display device 13 by the web browser 121. , Notify the coupon registration program 221 that the registration button 1205 has been pressed, and register the coupon. Program 221, information inputted from a supplier, i.e., registers ID, and condition and the coupon to the coupon management DB 223 (S1102).

  In the user terminal 3, the coupon management application 321 acquires latitude / longitude data representing the latitude / longitude detected by the situation detection unit 39, and specifies the area range 802 to which the latitude / longitude belongs from the area table 324. The coupon management application 321 acquires the area ID 801 corresponding to the specified area range 802 from the area table 324, and transmits the acquired area ID to the server 2 (S1103). The server 2 receives the area ID, and in the server 2, the coupon providing program 223 specifies the ID 603 corresponding to the received area ID, and records the record portions 701 and 703 corresponding to the specified ID 603 in the coupon management DB 223. The ID management metadata 322 is acquired (S1104), and the acquired ID management metadata 322 is transmitted to the user terminal 3 (S1105). In the user terminal 3, the coupon management application 321 receives the ID management metadata 322 from the server 2 and stores the ID management metadata 322 in the storage device 32. (S1106).

  In the user terminal 3, the coupon management application 321 is input to the situation detected by the situation detection unit 39 of the user terminal 3 (at least one situation inside and outside the user terminal 3) and the storage device 32 of the user terminal 3. The ID management metadata 322 is referred to using at least one of the existing information and it is determined whether or not the ID management metadata 322 satisfies a condition that the used information satisfies (S1107). Specifically, for example, the coupon management application 321 determines whether the position of the user terminal 3 (latitude and longitude from the situation detection unit 39) or the like meets any of the conditions 903 in the ID management metadata 322. . If the result of this determination is true (S1107: Yes), a condition matching ID 902 that is an ID corresponding to the satisfied condition 903 is transmitted to the server 2 by the coupon management application 321 (S1108). Even if the condition 903 is satisfied, the coupon management application 321 satisfies the condition when the user action (user situation) estimated from the user action table 325 satisfies the ID non-notification condition. If it is not present (S1107: No), the condition matching ID 902 may not be transmitted. The ID non-notification condition is also associated with each coupon and may be a condition (supplier viewpoint) defined by the supplier. The ID non-notification condition can be registered, for example, at the time of coupon registration using the screen of FIG. 12 or the like, and may be registered in a record of the coupon management DB 223. Therefore, the ID management metadata may include an ID non-notification condition (non-notification condition defined from the supplier viewpoint) associated with the coupon in addition to the ID and the condition. The ID non-notification condition may be prepared for each coupon or may be common to a plurality of coupons. For example, the ID non-notification condition may be that the moving speed of the user terminal 3 calculated based on the acceleration sensor value history and the latitude and longitude history exceeds a predetermined value. In such a case, even if the coupon is distributed, it is considered that the possibility that the user will come to the store where the coupon can be used is low, and the coupon management application 321 uses an area suitable for the position of the user terminal 3 as one condition element. You may skip transmission of ID corresponding to the conditions to include. In other words, the coupon management application 321 has a condition 903 that is satisfied, and the user behavior estimated from the user behavior table 325 is an ID non-notification condition of an ID (condition matching ID) corresponding to the condition 903. Is not satisfied, the condition matching ID 902 is transmitted to the server 2 (S1108). As another example of the area ID transmission control using the user behavior estimated from the user behavior table 325, for example, (1) the user's behavior history up to the area defined in the condition 903 is sent to the competitor store. If there is a drop-off, it is considered that the coupon is likely to be used, so a condition matching ID is transmitted. (2) It is specified from the user action table 325 that the user stays in a plurality of areas for a relatively long time. In this case, since it is assumed that the user is walking around, it is considered that the store visiting effect is high, so the coupon management application 321 sends the condition matching ID to the server 2, and (3) the user goes straight to the destination area. If it is determined from the user behavior table 325 that the user has moved to Management application 321 does not transmit the condition-satisfying ID to the server 2, examples may be cited such. The “destination-like area” may be, for example, an area to which a location registered in the schedule data referred to by the user terminal 3 belongs, or a destination (for example, use of a navigation function) input to the user terminal 3. Therefore, it may be an area to which the destination (entered) for the purpose belongs. In addition to user behavior, which is dynamic information that fluctuates in time units, the user's static information (gender, place of residence, age, etc.) is referenced to control whether or not to transmit the condition conforming ID. Also good.

  In the server 2, the coupon providing program 222 receives the condition matching ID from the coupon management application 321 and identifies the coupon 702 associated with the received condition matching ID from the coupon management DB 223. And the coupon provision program 222 transmits the coupon 323 containing the one part or all the information which the specified coupon 702 has to the coupon management application 321 of the user terminal 3 (S1110). The coupon management application 321 receives the coupon 323 and stores the coupon 323 in the storage device 32 (S1111). The user may display the coupon 323 on the touch panel 33 of the user terminal 3 and move to the store where the coupon 323 can be used based on information in the coupon 323 (for example, an address of a usable store, a map, etc.). it can.

  According to the above-described embodiment, the information transmitted from the user terminal 3 to the server 2 is not a latitude / longitude, user personal information, or the like, but a simple ID (for example, information that does not make sense by itself). Even if the ID is wiretapped, accurate information (for example, location) about the user is not known. For this reason, secure user guidance support can be realized. In addition, the user terminal 3 transmits the area ID of the area in which the user terminal 3 is located to the server 2 to acquire metadata related to the area, and does not have the metadata of the area in which the user terminal 3 is not located. The consumed storage capacity can be suppressed. Furthermore, the data stored in the user terminal 3 is relatively small data such as the ID management metadata 322 (and the area table 324), and the coupon 323 itself is not initially stored. For this reason, the memory capacity consumed by the user terminal 3 can be further suppressed.

  In the above-described embodiment, transmission / non-transmission of the condition matching ID is controlled based on the user behavior table 325 (or other data such as the user schedule data described above instead of or in addition to the table 325). Is done. For this reason, the communication load can be reduced by not sending the condition matching ID to the server 2 unnecessarily.

  The above-described embodiments are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to the embodiments. The present invention can be implemented in various other modes without departing from the gist thereof.

  For example, the user's guidance destination is not limited to a store but may be an event venue or other facilities, and the user guidance content is not limited to a coupon, but may be an email, advertisement data, or the like. Further, the e-mail and the advertisement data may be contents other than the user-guided contents.

  Further, the coupon management application 321 predicts a future user position for a predetermined time from the estimated time point (current) from the estimated user behavior, and instead of or in addition to the user position (latitude and longitude) at the estimated time point (current), The ID management metadata 322 may be referred to using the predicted user position (latitude and longitude). Thereby, a coupon corresponding to a condition that a user position in the future for a predetermined time from the estimated time point can be provided to the coupon management application 321 in advance. In addition, such processing may be performed periodically (for example, it may be performed every time latitude / longitude data is periodically acquired), or a satisfied condition is not found in S1107. It may be done only. In the latter case, only when the satisfied condition is not found in S1107, the ID corresponding to the condition that the user position in the future for a predetermined time from the estimated time can be transmitted to the server 2.
