[0042] Various types of information are stored in the storage unit 11. The various types of information include, for example, group information (to be described later), terminal information (to be described later), videos, one or more attribute values ​​associated with the videos, and map information.

[0043] The attribute value is, for example, the attribute value of the video. The attribute value of the video is, for example, environmental information. Environmental information is information about the environment in which the video was shot. Environmental information is, for example, location information, time information, weather information, temperature information, seasonal information, and a location identifier, which will be described later. Time information is information that identifies the time when the video was shot. The time when the video was shot may be a time around the time the video was shot, and accuracy is not required. Time information is, for example, the time, year / month / date / time, year / month / date / time / minute, year / month / date / time / minute / second, year / month / date, and month / day. In other words, the granularity of the time indicated by the time information does not matter. Weather information is information that identifies the weather at the location (or region) where the video was shot. Weather information is, for example, "sunny," "rain," "snow," or "cloudy." Temperature information is information that identifies the temperature at the location where the video was shot. Temperature information is, for example, "25 degrees" or "above 30 degrees." Seasonal information is information that identifies the season at the location where the video was shot. The season information is, for example, “spring,” “summer,” “early summer,” or “winter.” The road attribute value is the attribute value of the road on which the mobile terminal 2 has traveled.

[0044] Map information is used to obtain, for example, a location identifier corresponding to location information. The map information is, for example, in KIWI format, but the data structure is not critical. Location information is information that identifies a location. Location information is usually (latitude, longitude) or (latitude, longitude, altitude), but it may also be a location identifier, which will be described later.

[0045] A location identifier is information that identifies a location. The location identifier is, for example, the name of the location or the ID of the location. However, the location identifier may also be (latitude, longitude) or (latitude, longitude, altitude).

[0046] The group management unit 111 stores one or more pieces of group information. Group information is information that identifies multiple locations to be compared. The group information includes, for example, a location identifier for each of the multiple locations to be compared. The group information includes, for example, location information for each of the multiple locations to be compared.

[0047] The group information may be associated with a user identifier. That is, a group of multiple locations to be compared that each user desires may be managed. The group information associated with a user identifier is, for example, information registered by a user identified by the user identifier.

[0048] The terminal management unit 112 stores one or more pieces of terminal information. The terminal information is information relating to the mobile terminal 2. The terminal information here typically includes a terminal identifier, which is an identifier for the mobile terminal 2, and terminal communication information. The terminal information has, for example, the latest location information for the mobile terminal 2. The mobile terminal 2 here is typically a terminal capable of transmitting video. The terminal information is associated with the mobile terminal 2. The terminal information in the terminal management unit 112 is accumulated, for example, by transmission of terminal communication information and the like from the mobile terminal 2 when the mobile terminal 2 is in a state where it can transmit video.

[0049] The terminal identifier is information that identifies the mobile terminal 2. The terminal identifier may be a rights holder identifier that identifies the rights holder who is the user of the mobile terminal 2. The terminal identifier is, for example, the ID of the mobile terminal 2, the user identifier of the user of the mobile terminal 2, the name of the mobile terminal 2, the IP address of the mobile terminal 2, or the MAC address of the mobile terminal 2.

[0050] A rights holder is a person who has some right to a video shot by the mobile terminal 2. A rights holder is, for example, the owner of the video, the copyright holder of the video, the owner of the mobile terminal 2 that shot the video, or the person with the right to dispose of the video. A rights holder is, for example, the initial rights holder of the video. The rights holder is usually the owner of the mobile terminal 2, but it may be any person who has the rights to the video shot by the mobile terminal 2.

[0051] The right holder identifier may be a terminal identifier. The right holder identifier is, for example, the right holder's ID, name, email address, or telephone number. The right holder's ID is, for example, a user identifier.

[0052] The terminal communication information is information for communicating with the mobile terminal 2. The terminal communication information is, for example, the IP address of the mobile terminal 2, the MAC address of the mobile terminal 2, and the ID of the communication application installed in the mobile terminal 2.

[0053] The receiving unit 12 receives various types of information and instructions. The various types of information and instructions are, for example, location information, an inquiry (described later), a video, and a video associated with one or more attribute values. Note that a video associated with one or more attribute values ​​is appropriately referred to as an additional video. Note that the term "video" is a concept that includes the additional video.

[0054] The location receiving unit 121 receives location information from each of the multiple mobile terminals 2. Note that each of the multiple mobile terminals 2 here is a terminal capable of transmitting video. A terminal capable of transmitting video is, for example, a terminal currently shooting video, but it may also be a terminal that starts shooting video in response to receiving an instruction from the information processing device 1. The location receiving unit 121 normally receives location information from each of the multiple mobile terminals 2 continuously. Receiving continuously means receiving the information two or more times, for example, receiving the information constantly, receiving the information periodically, or receiving the information irregularly 22 or more times.

[0055] The inquiry receiving unit 122 receives inquiries from one or more user terminals 3. An inquiry can be said to be a request for transmission of screens based on videos of multiple locations to be compared. The inquiry includes specific information.

[0056] The specific information is information for identifying multiple locations to be compared. The specific information is, for example, a location identifier (e.g., a location name) that identifies each of the multiple locations, location information (e.g., (latitude, longitude)) that identifies each of the multiple locations, one location identifier, the location identifier of the location where the user terminal 3 is located, one location information, location information indicating the location where the user terminal 3 is located, or a user identifier.

[0057] The processing unit 13 performs various types of processing, such as processing performed by a video acquisition unit 131, a screen composition unit 132, or a rights holder processing unit 133.

[0058] The video acquisition unit 131 acquires videos transmitted from the mobile terminals 2 present at the locations specified by the identification information. The video acquisition unit 131 acquires videos in one of the following methods (1) and (2), for example: (1) When the video acquisition unit 131 determines the mobile terminal 2 to which the video is to be transmitted

[0059] The video acquisition unit 131 transmits a video transmission instruction to the mobile terminal 2 located at each of the multiple locations specified by the specific information, and receives the video from the mobile terminal 2 in response to the transmission of the transmission instruction. In this case, the video acquisition unit 131 includes the following terminal determination means 1311, instruction transmission means 1312, and video reception means 1313.

[0060] The terminal determination means 1311 uses the location information of the mobile terminal 2 received by the location receiving unit 121 to determine the mobile terminal 2 present at each of the multiple locations specified by the identification information.

[0061] The instruction sending means 1312 sends a transmission instruction to each of the plurality of mobile terminals 2 determined by the terminal determining means 1311. The transmission instruction is an instruction to transmit a moving image.

[0062] The video receiving means 1313 receives video from each of the plurality of mobile terminals 2 to which a transmission instruction has been transmitted. (2) When the mobile terminal 2 determines whether to transmit video

[0063] The video acquisition unit 131 includes, for example, an instruction sending unit 1312 and a video receiving unit 1313 described below.

[0064] The instruction sending means 1312 sends an inquiry based on the specific information to the multiple mobile terminals 2. The multiple mobile terminals 2 here are multiple mobile terminals 2 that can send video. The multiple mobile terminals 2 here are typically all mobile terminals 2 that can send video. The multiple mobile terminals 2 here are, for example, multiple mobile terminals 2 that are managed by the terminal management unit 112 as being in a state where they can send video.

[0065] The query based on the identifying information is transmitted to the mobile terminal 2 and may be the same information as the received query or may be different information. The query based on the identifying information may include the received identifying information, may include multiple pieces of location information corresponding to the received identifying information, or may include multiple location identifiers corresponding to the received identifying information.

[0066] In response to the transmission of the inquiry, the video receiving means 1313 receives video from each of the plurality of mobile terminals 2 determined to correspond to the specific information.

[0067] The screen configuration unit 132 configures a screen based on multiple videos acquired by the video acquisition unit 131. It is preferable for a single screen to include multiple videos. It is also preferable for a single screen to include all videos acquired by the video acquisition unit 131. However, a single screen may include thumbnail images based on frames constituting each of the multiple videos, or may include a portion (e.g., one) of the multiple videos and thumbnail images based on frames constituting one or more other videos. It is preferable for a portion (window) of a single screen to include one or more videos. Furthermore, configuring a screen means acquiring screen information that is the basis for displaying the screen. The screen information is described in, for example, HTML, XML, or the like, but the format is not important.

[0068] The ranking means 1321 acquires one or more attribute values ​​of each of the multiple videos and ranks the multiple videos using the attribute values. The attribute values ​​are, for example, the analysis results of the video and the distance from the user terminal 3. The analysis results of the video are, for example, the price of a specific product in the video and the degree of road congestion based on the number of cars. The distance from the user terminal 3 is the distance acquired using the location information corresponding to the video and the location information transmitted from the user terminal 3.

[0069] The ranking means 1321 performs object recognition processing on one frame of a video taken inside each of multiple supermarkets, for example, to determine the object in the frame, and obtains the price, which is a number near the object, through character recognition processing. Next, the ranking means 1321 assigns a rank (for example, any natural number greater than or equal to 1) to the videos in order of lowest price of the same object, for example.

[0070] The ranking means 1321, for example, performs object recognition processing on one frame in each video of a plurality of different expressways, obtains the number of cars or the distance between cars in that frame, and obtains the road congestion level (level) using the number of cars or the distance. Note that the ranking means 1321 obtains the level by, for example, referring to a correspondence table containing a plurality of pieces of correspondence information having ranges of the number of cars and levels, or a correspondence table containing a plurality of pieces of correspondence information having ranges of distance between cars and levels. Next, the ranking means 1321, for example, assigns a level to each video.

[0071] The ranking means 1321 calculates the distance for each of the plurality of mobile terminals 2, for example, using the location information associated with the video transmitted from the mobile terminal 2 and the location information transmitted from the user terminal 3. Next, the ranking means 1321 assigns a rank to each of the videos transmitted from the mobile terminal 2 in order of the shortest distance, for example.

[0072] The configuration unit 1322 configures one screen based on each of the multiple videos. It is preferable that the configuration unit 1322 configures one screen according to the ranking of each of the multiple videos. Note that the one screen according to the ranking is, for example, a screen including multiple videos sorted in order of rank, or a screen indicating the rank of each video. Note that, as described above, it is preferable that the one screen include all of the multiple videos, but it may also include thumbnail images using still images that configure each video, or it may include only some of the videos.

[0073] The right holder processing unit 133 performs right holder processing. The right holder processing is processing related to a right holder identified by a right holder identifier associated with a video. Note that the video here is, for example, a video acquired by the video acquisition unit 131. The video here is, for example, a video received by the receiving unit 12.

[0074] The rights holder processing unit 133 performs rights holder processing, which is processing in response to the transmission of a screen by the screen transmission unit 141, and is processing related to a rights holder identified by a rights holder identifier associated with each of multiple videos corresponding to the screen. The rights holder processing is, for example, a first security processing, a second security processing, a third security processing, a fourth security processing, and a compensation processing, which will be described later.

[0075] The right holder identifier associated with the video is, for example, the right holder identifier corresponding to the mobile terminal 2 that transmitted the video, or the identifier of the user of the user terminal 3 to which the video was transmitted. The user of the user terminal 3 is the user who transmitted the inquiry.

[0076] The first security means 1331 performs a first security process of storing the video received by the receiving unit 12 in association with an attribute value set corresponding to the video. The attribute value set includes one or more attribute values. The first security means 1331 stores the video in a blockchain, for example.

[0077] The second security means 1332 performs a second security process of storing the video received by the receiving unit 12 in association with the rights holder identifier corresponding to the video. The second security means 1332 stores the video in a blockchain, for example.

[0078] The third security means 1333 stores a right holder identifier that identifies the user of the user terminal 3, in association with the video. The third security means 1333 stores the right holder identifier, for example, in the storage unit 11 or a blockchain. The third security means 1333 may store a right holder identifier that identifies the user of the user terminal 3 for multiple videos received by the receiving unit 12. The third security means 1333 may store temporally consecutive screens (video of the screens) transmitted by the screen transmission unit 141, paired with the right holder identifier.

[0079] The video is stored in, for example, the storage unit 11, but may also be stored in other devices, such as other devices that make up the blockchain.

[0080] The fourth security means 1334 performs a fourth security process to store security information. The security information includes access information for accessing the stored video. The order of storing the video and performing the fourth security process on the security information corresponding to the video does not matter.

[0081] The fourth security means 1334 performs, for example, a fourth security process of accumulating security information including access information for accessing the multiple videos acquired by the video acquisition unit 131. The fourth security means 1334 performs, for example, a fourth security process of accumulating security information including access information for accessing the video on the screen transmitted by the screen transmission unit 141 to the user terminal 3.

[0082] It is preferable that the fourth security means 1334 stores the security information in a blockchain. That is, it is preferable that the fourth security means 1334 stores the security information in a distributed ledger of the blockchain. It is preferable that the fourth security means 1334 registers the security information as an NFT (non-fungible token). It is preferable that the fourth security means 1334 registers the security information in a distributed file system in an IPFS (Inter Planetary File System) network.

[0083] The security information is information for ensuring the originality of a video. The security information can be said to be header information for the video. The security information is, for example, access information and a set of attribute values. It is preferable that the security information has, for example, one or more rights holder identifiers. When the security information has multiple rights holder identifiers, the rights holder of the video may be shared, and the multiple rights holder identifiers may be rights holder history information. The rights holder history information is a set of rights holder identifiers and is information that indicates the history of the rights holder. The fourth security process can ensure the originality of the security information of the registered video (which may be a video on a screen). By ensuring the originality of the security information, the originality of the video corresponding to the security information is also ensured. The access information is information for accessing the video. The access information is information that identifies the storage location of the video. The access information is, for example, a URL or a URI.

[0084] The remuneration means 1335 performs remuneration processing for each right holder identified by a right holder identifier associated with the video acquired by the video acquisition unit 131. Note that such a right holder identifier is, for example, the owner of the mobile terminal 2.

[0085] The reward process is a process of providing a reward. The reward process is, for example, a process of increasing points managed in pairs with one or more rights holder identifiers associated with a video. The reward process is, for example, a process of depositing money to a rights holder identified by one or more rights holder identifiers associated with a video. The reward process is, for example, a process of transmitting a video or other content to a user terminal 3 of a rights holder identified by one or more rights holder identifiers associated with a video. The reward process is not limited to the type of merit provided to the rights holder identified by one or more rights holder identifiers associated with the video. The reward may be, for example, money, points, goods, content, or the like, and the type of merit is not limited.

[0086] It is preferable that the compensation means 1335 acquires one or more attribute values ​​of the video corresponding to the screen transmitted by the screen transmission unit 141, and performs compensation processing, which is a process of determining a compensation to the rights holder of the video using the one or more attribute values ​​and providing the compensation.

[0087] Here, the one or more attribute values ​​are, for example, the amount of video data, the duration of the video, the number of frames of the video, and the resolution of the video.

[0088] The reward means 1335 preferably acquires a reward amount corresponding to a service identifier that identifies a service provided for a target video, and performs a reward process that awards a reward corresponding to the reward amount. The service identifier may be, for example, "view" or "purchase." In this case, the storage unit 11 stores, for example, the reward amount corresponding to the service identifier, or information for determining the reward amount corresponding to the service identifier.

[0089] The reward means 1335 performs reward processing, which is a process of obtaining a reward amount using, for example, one or more pieces of information from one or more attribute values ​​and one or more service identifiers, and providing a reward corresponding to the reward amount. In such a case, for example, an arithmetic expression or a correspondence table corresponding to each of multiple service identifiers is stored in the storage unit 11. The arithmetic expression is a formula for calculating the reward amount using one or more attribute values ​​as parameters. The correspondence table is a table having multiple pieces of correspondence information for managing reward amounts corresponding to one or more attribute values.

[0090] The reward means 1335 typically performs a process of charging a user who has enjoyed a service related to the target video with a reward. The process of charging a user with a reward is, for example, a process of charging the user with the amount of reward obtained. The process of charging a user with a reward is, for example, a process of charging the user with the amount of reward obtained and the amount of profit obtained by the operator of the information processing device 1. The process of charging a user with a reward is, for example, a process of deducting points corresponding to the user who has enjoyed the service, a settlement process using the user's credit card number, etc. The user who has enjoyed the service is typically the user of the user terminal 3.

[0091] The transmitting unit 14 transmits various types of information or instructions, such as a screen.

[0092] The screen transmission unit 141 transmits one of the screens acquired by the screen composition unit 132 to the user terminal 3 that has sent the inquiry. The screen transmission unit 141 usually transmits to the user terminal 3 a screen including videos taken at multiple locations to be compared. <Details of the components of the mobile terminal 2>

[0093] Various types of information are stored in the moving storage unit 21. The various types of information include, for example, video, attribute value sets, rights holder identifiers, camera attribute values, and map information. The camera attribute values ​​are attribute values ​​of the camera. The camera attribute values ​​include, for example, the angle of view, direction information, and resolution.

[0094] For example, one or more attribute values ​​constituting an attribute value set correspond to one or more still images constituting a moving image. The one or more attribute values ​​may correspond to all of the still images, some of the still images, or multiple still images.

[0095] The mobile receiving unit 22 receives various information and instructions, such as transmission instructions and inquiries.

[0096] The movement processing unit 23 performs various processes, such as processes performed by a position acquisition unit 231, a photographing unit 232, an attribute value acquisition unit 233, and a configuration unit 234.

[0097] The movement processing unit 23 determines whether the location information acquired by the location acquisition unit 231 matches the query received by the mobile receiving unit 22. The movement processing unit 23 determines whether any one or more location identifiers or any one or more location information included in the query satisfies a location condition with respect to the location information acquired by the location acquisition unit 231. The location condition means that the two locations are the same or nearby locations. Examples of the location condition include the location indicated by the location information acquired by the location acquisition unit 231 being the same as the location identified by the location identifier or location information included in the query, or the distance between the point indicated by the location information acquired by the location acquisition unit 231 and the point identified by the location identifier or location information included in the query being within a threshold or less than a threshold.

[0098] The location acquisition unit 231 acquires location information. The location acquisition unit 231 typically acquires location information that identifies the current location of the mobile terminal 2. The location acquisition unit 231 acquires the location information using, for example, a GPS receiver. However, the means or algorithm by which the location acquisition unit 231 acquires the location information is not critical.

[0099] The photographing unit 232 photographs a video. For example, the photographing unit 232 photographs a video while the mobile terminal 2 is moving. It is preferable that the photographed video be associated with location information acquired by the location acquisition unit 231. It is also preferable that the photographed video be associated with one or more attribute values ​​acquired by the attribute value acquisition unit 233, which will be described later.

[0100] It is preferable that the imaging unit 232 stores the captured video in the mobile storage unit 21. When the imaging unit 232 stores video in the mobile storage unit 21, which has a limited storage capacity, it is preferable that the imaging unit 232 overwrites new video in the area where old video is stored. In other words, it is preferable that the structure of the mobile storage unit 21 is a ring buffer structure.

[0101] The photographing unit 232 may start photographing a video in response to, for example, receiving a transmission instruction. The photographing unit 232 may start photographing a video when, for example, it is determined that a location condition is met in response to a received inquiry. The photographing unit 232 starts photographing a video in response to, for example, receiving a photographing instruction input from a user.

[0102] The attribute value acquisition unit 233 acquires one or more camera attribute values ​​including direction information indicating the direction in which the image is captured by the image capture unit 232. It is preferable that the attribute value acquisition unit 233 acquires one or more attribute values ​​including the camera attribute value.

[0103] The attribute value acquisition unit 233 acquires, for example, one or more attribute values. The one or more attribute values ​​may be referred to as an attribute value set. The attribute value acquisition unit 233 acquires time information from a clock (not shown), for example, during shooting. The attribute value acquisition unit 233 acquires time information, for example, constantly, at predetermined intervals, or when acquisition conditions are met. The attribute value acquisition unit 233 acquires time information from a clock (not shown), for example, during shooting, and acquires seasonal information corresponding to the time information. The attribute value acquisition unit 233 acquires weather information corresponding to location information, for example, from a server (not shown). The attribute value acquisition unit 233 acquires weather information, for example, constantly, at predetermined intervals, or when acquisition conditions are met. The attribute value acquisition unit 233 acquires temperature information, for example, during shooting. The movement processing unit 23 acquires temperature information corresponding to location information, for example, from a server (not shown). The movement processing unit 23 acquires temperature information, for example, from a temperature sensor installed in the moving object. The movement processing unit 23 acquires temperature information, for example, constantly, at predetermined intervals, or when an acquisition condition is satisfied, such as when the analysis result of the video satisfies a predetermined condition.

[0104] The attribute value acquisition unit 233, for example, acquires from map information a location identifier corresponding to the location information acquired by the location acquisition unit 231, and associates the location identifier with the video. The attribute value acquisition unit 233, for example, acquires from map information a location identifier that is a location identifier corresponding to the location information acquired by the location acquisition unit 231 and that satisfies a specific condition, and associates the location identifier with the video. The specific condition is, for example, that the location identifier is a specific type of location identifier (for example, a station name or a building name).

[0105] Note that the association with the moving image may be association with frames that make up the moving image, or association with the entire moving image.

[0106] The attribute value acquisition unit 233 acquires, for example, one or more tags for the video captured by the image capture unit 232 and associates the tags with the video. Note that a tag can also be considered an attribute value.

[0107] The attribute value acquisition unit 233, for example, analyzes the video captured by the image capture unit 232 and acquires one or more tags for the video.

[0108] The attribute value acquisition unit 233 acquires one or more tags using, for example, one or more moving object attribute values ​​acquired during image capture by the image capture unit 232. The moving object attribute values ​​are, for example, CAN data.

[0109] The attribute value acquisition unit 233 may, for example, determine one or more still images that match the video tag condition and acquire a tag that pairs with the video tag condition. The attribute value acquisition unit 233 may also associate the tag with the one or more still images. Note that the still images are frames that make up the video.

[0110] For example, if the video tag condition is "the number of cars with a distance between them within a threshold is equal to or greater than a threshold and the car's moving speed is equal to or less than a threshold," and the tag paired with the video tag condition is "traffic jam," the attribute value acquisition unit 233 analyzes frames of the video, recognizes multiple cars, and acquires the distances between each of the multiple cars. The attribute value acquisition unit 233 also acquires the number of cars with a distance between them within a threshold. The attribute value acquisition unit 233 also acquires the moving distance and frame rate of a single car in multiple frames, and acquires the car's speed. The attribute value acquisition unit 233 then determines whether the video tag condition is met using the number of cars with a distance between them within a threshold and the car's speed. If the video tag condition is met, the attribute value acquisition unit 233 acquires the tag "traffic jam" paired with the video tag condition. The attribute value acquisition unit 233 may also associate the tag "traffic jam" with the analyzed frame of the analyzed video.

[0111] The attribute value acquisition unit 233 may, for example, determine one or more moving object attribute values ​​that match the attribute value tag condition, and acquire a tag that pairs with the attribute value tag condition. The attribute value acquisition unit 233 may also associate the tag with a video that pairs with the one or more moving object attribute values.

[0112] For example, if the attribute value tag condition is "driving time at a speed of less than 30 km for 10 minutes or more and the proportion of times during that driving time when the speed is less than 30% is 80% or more," and the tag paired with the attribute value tag condition is "traffic jam," the attribute value acquisition unit 233 uses the speed history contained in the CAN data associated with each field of the video to detect CAN data that matches the attribute value tag condition, acquires the tag "traffic jam" that matches the attribute value tag condition, and associates the tag with the field associated with the CAN data. Note that the CAN data associated with each field of the video is CAN data acquired at the same time that the field was captured.

[0113] The composition unit 234 associates the acquired location information with the video and acquires an additional video. The composition unit 234 acquires, for example, an additional video in which one or more camera attribute values ​​acquired by the attribute value acquisition unit 233 are also associated with the video. The composition unit 234 acquires, for example, an additional video in which one or more attribute values ​​acquired by the attribute value acquisition unit 233 are also associated with the video. The additional video usually includes location information.

[0114] The mobile transmission unit 24 transmits various types of information to the information processing device 1. The various types of information are, for example, moving images and additional moving images. The mobile transmission unit 24 may continuously transmit moving images acquired by the shooting unit 232 to the information processing device 1. In such cases, the moving images are usually associated with location information and time information.

[0115] For example, in response to receiving a transmission instruction, the mobile transmission unit 24 transmits the video captured by the shooting unit 232 to the information processing device 1 .

[0116] For example, when it is determined that the location condition is met for the received inquiry, the mobile transmitting unit 24 transmits the video captured by the photographing unit 232 to the information processing device 1 .

[0117] The movement output unit 25 outputs various types of information, such as a moving image, an additional moving image, and a set of attribute values.

[0118] The concept of output includes displaying on a display, projection using a projector, printing on a printer, sound output, transmission to an external device, storage on a recording medium, and delivery of processing results to other processing devices or other programs. <Details of Components of the User Terminal 3>

[0119] Various types of information are stored in the user storage unit 31. The various types of information include, for example, a user identifier, a video, an inquiry, and map information.

[0120] The user receiving unit 32 receives various instructions and information. The various instructions and information are, for example, inquiries. The inquiries received by the user receiving unit 32 include, for example, specific information.

[0121] Reception is a concept that includes the reception of information entered from input devices such as a keyboard, mouse, or touch panel, the reception of information transmitted via a wired or wireless communication line, and the reception of information read from recording media such as an optical disk, magnetic disk, or semiconductor memory.

[0122] The user receiving unit 32 receives, for example, an inquiry from a user. Such an inquiry is an instruction to acquire videos of multiple locations to be compared. The inquiry received from the user may be simply a button press or a menu item selection, or may include input of one or more location identifiers, or may include input of one or more pieces of location information.

[0123] For example, when the location information acquired by the user processing unit 33 is specific location information (for example, a point before a branch point of an expressway such as the Tomei Expressway and the Shin-Tomei Expressway), the user accepting unit 32 acquires an inquiry including the location information. Acquisition of such an inquiry may also be considered as acceptance of an inquiry.

[0124] The user processing unit 33 performs various types of processing. The various types of processing are, for example, processing performed by the location acquisition unit 331 and the inquiry acquisition unit 332. The various types of processing are, for example, processing to create a data structure for transmitting various instructions and information received by the user reception unit 32. The various types of processing are, for example, processing to create a structure for transmitting information received by the user reception unit 35.

[0193] Next, an example of the fourth maintenance process of S413 will be described with reference to the flowchart of FIG.

[0194] (S801) The fourth security unit 1334 acquires access information that identifies the storage destination of the video.

[0195] (S802) The fourth maintenance unit 1334 acquires a set of attribute values ​​corresponding to the stored moving images.

[0196] (S803) The fourth security means 1334 constructs security information including the access information acquired in S801, the attribute value set acquired in S802, and the rights holder identifier of the video. If a new rights holder identifier has been acquired, the fourth security means 1334 constructs security information including, for example, the new rights holder identifier and the original rights holder identifier. (S804) The fourth security means 1334 stores the security information constructed in S803. The process returns to the upper level process.

[0197] In S804, if preservation information for a video corresponding to the preservation information to be stored has been stored, the preservation information configured in S803 is overwritten with the preservation information. This allows, for example, the transition of rights holders of the video to be managed. Furthermore, the fourth preservation unit 1334 stores the preservation information in a blockchain, for example.

[0198] Next, an example of the reward process in S414 will be described with reference to the flowchart in FIG.

[0199] (S901) The reward means 1345 assigns 1 to a counter i.

[0200] (S902) The reward unit 1345 determines whether the i-th video that was the basis for composing the screen exists. If the i-th video exists, the process proceeds to S903, and if not, the process returns to the upper process.

An example of such comparison target location acquisition processing has been described with reference to the flowchart in FIG.

[0214] (S1007) Video receiving means 1313 determines whether or not video or the like has been received from any mobile terminal 2. If video or the like has been received, the process proceeds to S1008, and if not, the process returns to S1007.

[0215] (S1008) The video acquisition unit 131 acquires location information paired with the video received in S1007.

[0216] (S1009) The video acquisition unit 131 determines whether the location information acquired in S1008 satisfies the location condition of any of the location information acquired in S1006 that does not correspond to video. If the location condition is satisfied, the process proceeds to S1010; if not, the process proceeds to S1016.

[0219] In the flowchart of FIG. 10, the process ends when the power is turned off or an interrupt occurs to end the process.

[0220] Next, a first operation example of the mobile terminal 2 will be described using the flowchart in Fig. 11. The first operation example is a case where the information processing device 1 determines the mobile terminal 2 to which to transmit a video. In other words, the flowchart for the mobile terminal 2 in Fig. 11 corresponds to the flowchart for the information processing device 1 in Fig. 4.

[0221] (S1101) The mobile terminal 2 determines whether or not a start instruction has been received. If a start instruction has been received, the process proceeds to S1102, and if a start instruction has not been received, the process proceeds to S1101.

The movement transmission unit 24 transmits the information to the information processing device 1.

[0224] (S1104) The movement processing unit 23 determines whether or not to end the process. If the process is to be ended, the process returns to S1101. If the process is not to be ended, the process proceeds to S1105. The process is ended, for example, when an end instruction is input by the user.

[0225] (S1105) The mobile receiving unit 22 determines whether or not a transmission instruction has been received from the information processing device 1. If a transmission instruction has been received, the process proceeds to S1106, and if a transmission instruction has not been received, the process returns to S1102.

[0226] (S1106) The image capturing unit 232 acquires a video.

[0227] (S1107) The attribute value acquisition unit 233 acquires one or more attribute values. The composition unit 234 acquires a terminal identifier from the moving storage unit 21. The composition unit 234 associates one or more attribute values ​​and a terminal identifier with the moving image to compose information to be transmitted. Note that each frame constituting the moving image is associated with, for example, time information acquired by the attribute value acquisition unit 233, position information acquired by the position acquisition unit 231, etc.

[0228] (S1108) The mobile transmission unit 24 transmits the video etc. constructed in S1107 to the information processing device 1. Return to S1104. Note that the length and amount of data of the video transmitted by the mobile transmission unit 24 at one time are not important.

[0229] 11, the photographing unit 232 starts photographing in response to receiving a transmission instruction. However, the photographing unit 232 may start photographing in response to receiving a start instruction.

[0230] In the flowchart of FIG. 11, the process ends when the power is turned off or an interrupt occurs to end the process.

[0231] Next, a second operation example of the mobile terminal 2 will be described using the flowchart in Fig. 12. The second operation example is a case where the mobile terminal 2 determines whether or not to transmit a video to the information processing device 1. In other words, the flowchart of the mobile terminal 2 in Fig. 12 corresponds to the flowchart of the information processing device 1 in Fig. 10.

[0232] (S1201) The mobile receiving unit 22 determines whether or not an inquiry has been received from the information processing device 1. If an inquiry has been received, the process proceeds to S1202, and if an inquiry has not been received, the process returns to S1201.

[0233] (S1202) The movement processing unit 23 performs a comparison position acquisition process. The comparison position acquisition process is the same as the process described with reference to the flowchart in FIG.

If the i-th location information exists, the process proceeds to S1206, and if not, the process returns to S1201.

[0237] (S1206) The movement processing unit 23 determines whether the location information acquired in S1203 and the i-th location information satisfy the location condition. If the location condition is satisfied, the process proceeds to S1207, and if the location condition is not satisfied, the process proceeds to S1211.

[0238] (S1207) The image capturing unit 232 acquires a video.

[0239] (S1208) Attribute value acquisition unit 233 acquires one or more attribute values. Composition unit 234 acquires a terminal identifier from moving storage unit 21. Composition unit 234 associates the one or more attribute values ​​and the terminal identifier with the video, and composes information to be transmitted.

[0240] Each frame constituting the moving image is associated with, for example, time information acquired by the attribute value acquisition unit 233, position information acquired by the position acquisition unit 231, and the like.

[0241] (S1209) The mobile transmission unit 24 transmits the video and the like constructed in S1208 to the information processing device 1.

[0242] (S1210) The movement processing unit 23 determines whether or not to end the transmission of the video, etc. If the transmission of the video, etc. is to be ended, the process returns to S1201, and if the transmission of the video, etc. is not to be ended, the process returns to S1207. Note that the transmission of the video, etc. is ended, for example, when a transmission unnecessary command is received from the information processing device 1 or when an end instruction is received from the user of the mobile terminal 2.

[0243] (S1211) The movement processing unit 23 increments the counter i by 1. The process returns to S1205.

[0244] 12, before acquiring the video in S1207, the information processing device 1 may be inquired of whether or not to transmit the video. In such a case, the mobile transmission unit 24 transmits an inquiry including, for example, location information and other attribute values ​​to the information processing device 1. Then, in response to the inquiry received from the current location information of multiple mobile terminals 2, the information processing device 1 determines, for each comparison location, one mobile terminal 2 to transmit the video to, based on the location information and other attribute values. This determination method may be the same as the operation at S510 in the flowchart of FIG. 5.

[0245] In the flowchart of FIG. 12, the process ends when the power is turned off or an interrupt occurs to end the process.

[0246] Next, an example of the operation of the user terminal 3 will be described with reference to the flowchart of FIG.

[0247] (S1301) The user reception unit 32 determines whether or not an inquiry has been received. If an inquiry has been received, the process proceeds to S1302, and if an inquiry has not been received, the process returns to S1301.

[0248] (S 1302 ) The user processing unit 33 acquires the user identifier from the user storage unit 31 .

[0249] (S1303) The inquiry acquisition unit 332 uses the inquiry received in S1301 to construct an inquiry to be sent. The inquiry to be sent is usually associated with a user identifier. The inquiry to be sent includes, for example, the location information acquired by the user processing unit 33 or the location identifier acquired by the location acquisition unit 331.

[0250] (S1304) The user transmission unit 34 transmits the inquiry constructed in S1303 to the information processing device 1.

[0251] (S1305) The user receiving unit 35 determines whether or not a screen has been received from the information processing device 1. If a screen has been received, the process proceeds to S1306, and if a screen has not been received, the process proceeds to S1307.

[0252] (S1306) User processing unit 33 creates a screen to be output based on the received screen. User output unit 36 ​​outputs this screen.

[0253] (S1307) The user processing unit 33 determines whether or not to end the screen output. If the screen output is to be ended, the process returns to S1301. If the screen output is not to be ended, the process returns to S1305. Note that the screen output is ended, for example, when an end instruction is received from the user.

[0254] In the flowchart of Fig. 13, the process ends when the power is turned off or an interrupt occurs to end the process.

[0255] A specific example of the operation of the information system A in this embodiment will be described below.

[0256] Assume that the group management table shown in FIG. 14 is stored in the group management unit 111 of the information processing device 1. The group management table is a table for managing group information. The group management table is a table for managing information for determining multiple locations to be compared with specific information included in a received inquiry. The group information is the set of location identifiers shown in FIG. 14 , but it may also be considered to include specific information. The group management table manages records having an "ID," "specific information," and "set of location identifiers." The "ID" is information for identifying a record. Here, the "specific information" is, for example, a store name (supermarket name), location information (latitude, longitude), or a user identifier. The "set of location identifiers" is a set of location identifiers that identify each of multiple locations to be compared. Here, the location identifiers are the store name (supermarket name), location information (latitude, longitude), and location name (name of a location on a highway). Note that the store name is an example of a location name.

[0257] It is assumed that the terminal management unit 112 stores the terminal management table shown in Fig. 15. The terminal management table manages records having "ID" and "terminal information." The "terminal information" here includes "terminal identifier," "terminal communication information," and "location information." The "location information" is the latest location information of the mobile terminal 2.

[0258] It is assumed that, when the mobile terminal 2 is in a state where it is able to provide video, it continuously transmits its current location information, associated with its terminal identifier, to the information processing device 1. The location receiving unit 121 of the information processing device 1 receives the location information associated with the terminal identifier from each mobile terminal 2. The processing unit 13 then stores the location information in the terminal management table ( FIG. 15 ), associated with the terminal identifier.

[0259] Map information is stored in the storage unit 11 of the information processing device 1. The map information has store names paired with location information of the stores, and location names paired with location information of the locations.

[0260] In this situation, the following four specific examples will be described. Specific Example 1 is a case where a user inputs a location identifier (here, the name of a single store) that identifies multiple locations to be compared into a smartphone, and obtains videos of multiple locations, including locations identified by other location identifiers that are paired with the location identifier. Specific Example 2 is a case where a user presses a specific button in a specific app on the smartphone to obtain videos of each of the multiple locations to be compared. Specific Example 3 is a case where a user inputs a user identifier on the screen of a specific app on the smartphone and then presses a button to obtain videos of each of the multiple locations to be compared. Specific Example 4 is a case where, when a user passes a specific point while traveling by car, a video is output to a navigation device to show the conditions of multiple roads that branch off after passing the specific point.

[0261] (Specific Example 1) It is assumed that a user launches an app on the user terminal 3. The app is capable of acquiring and outputting videos of multiple comparison locations. Next, the app is launched on the user terminal 3. The user terminal 3 then outputs a screen for inputting specific information. Note that this screen has a field for inputting specific information and a "send" button. The "send" button is a button for sending an inquiry to the information processing device 1.

[0262] Next, the user inputs the specific information "Supermarket A" on the screen and presses the "Send" button.

[0263] Then, the user receiving unit 32 of the user terminal 3 receives the query "<specific information> Supermarket A". Next, the user processing unit 33 obtains the user identifier "U001" from the user storage unit 31. The query obtaining unit 332 uses the received query to construct a query to be sent, "<user identifier> U001 <specific information> Supermarket A". Next, the user sending unit 34 sends the query to the information processing device 1.

[0264] Next, the inquiry receiving unit 122 of the information processing device 1 receives the inquiry “<user identifier> U001 <specific information> Supermarket A” from the user terminal 3 .

[0265] Next, the terminal determination means 1311 acquires the specific information "Supermarket A" contained in the received inquiry. The terminal determination means 1311 acquires the location identifier set "Supermarket B, Supermarket C, Supermarket D" that pairs with the specific information "Supermarket A" from the group management table (FIG. 14). Next, the terminal determination means 1311 acquires the location information of "Supermarket A, Supermarket B, Supermarket C, Supermarket D" by referring to the map information in the storage unit 11. The location information of each of these four supermarkets is calculated as follows: (x ２１ , y ２１ ) (x ２２ , y ２２ ) (x ２３ , y ２３ ) (x ２４ , y ２４). Next, the terminal determination means 1311 determines the location information of the mobile terminal 2 that satisfies the location condition for the location information of each of the four supermarkets (that is, that is located in that supermarket) from the terminal management table (FIG. 15). Here, it is assumed that the terminal determination means 1311 has acquired the terminal identifier "T001" of the mobile terminal 2 that is located in supermarket A, the terminal identifier "T002" of the mobile terminal 2 that is located in supermarket B, the terminal identifier "T003" of the mobile terminal 2 that is located in supermarket C, and the terminal identifier "T004" of the mobile terminal 2 that is located in supermarket D from the terminal management table (FIG. 15).

[0266] Next, the instruction sending means 1312 acquires the terminal communication information paired with each of the acquired four terminal identifiers from the terminal management table (FIG. 15). Next, the instruction sending means 1312 transmits a transmission instruction to the mobile terminal 2, which is the communication destination indicated by each of the four pieces of terminal communication information.

[0267] Next, the mobile receiving unit 22 of each of the four mobile terminals 2 receives a transmission instruction from the information processing device 1. Next, the photographing unit 232 acquires the video. Furthermore, the attribute value acquisition unit 233 acquires one or more attribute values. Here, it is assumed that the attribute value acquisition unit 233 acquires an attribute value that is the price of a product in the video. Furthermore, the configuration unit 234 acquires a terminal identifier from the mobile storage unit 21. The configuration unit 234 associates one or more attribute values ​​and a terminal identifier with the video to configure information to be transmitted. Next, the mobile transmitting unit 24 transmits the video, etc. to the information processing device 1.

[0268] Next, the video receiving means 1313 of the information processing device 1 receives the video etc. from each of the four mobile terminals 2 to which the transmission instruction was sent. The video etc. has one or more attribute values ​​including the price of the product in the video, and a terminal identifier. Next, the video acquisition unit 131 pairs the received video and attribute values ​​with the terminal identifier for each of the four mobile terminals 2, and temporarily stores them in a buffer (not shown).

[0269] Next, the ranking means 1321 obtains a rank (a natural number from "1" to "4") for each of the four mobile terminals 2 in order of lowest price using the prices corresponding to the mobile terminals 2. Next, the configuration means 1322 constructs a screen in which each of the four obtained videos is arranged from top to bottom according to its ranking. The configuration means 1322 also constructs a screen including a map showing the locations of the four places (supermarkets) to be compared. The configuration means 1322 also constructs a screen having information listing the attribute values ​​(here, prices) of the four places to be compared in order of rank. The configuration means 1322 also constructs a screen including the current time obtained from a clock (not shown).

[0270] Next, the screen transmission unit 141 transmits the screen constructed by the screen construction unit 132 to the user terminal 3 that has transmitted the inquiry.

[0271] Next, the user receiving unit 35 of the user terminal 3 receives the screen from the information processing device 1. Next, the user processing unit 33 creates a screen to be output based on the received screen. The user output unit 36 ​​outputs the screen. An example of such a screen is shown in FIG. 16. In FIG. 16, 1601 to 1604 are windows in which videos taken inside each supermarket are output. The videos are arranged in order of the ranking of each supermarket. 1605 is the ranking result of the attribute value (here, price). 1606 shows the locations of the four supermarkets on a map.

[0272] Through the above process, the user can obtain multiple super videos that he or she wishes to compare, and can also obtain a screen according to the ranking of each of the multiple videos.

[0273] (Specific Example 2) Assume that a user launches an app on the user terminal 3. The app is capable of acquiring and outputting videos of multiple comparison locations. Next, the app is launched on the user terminal 3, and a screen is output. Note that this screen has a "Send" button. Also, this screen does not have any components such as fields for inputting specific information. The "Send" button is a button for sending an inquiry to the information processing device 1.

[0274] Next, the user presses the "Send" button on the screen. Then, the location acquisition unit 331 of the user terminal 3 receives location information (x ２１ , y ２１ Next, the user receiving unit 32 acquires the position information (x ２１ , y ２１ Next, the user processing unit 33 acquires the user identifier "U001" from the user storage unit 31. The inquiry acquisition unit 332 uses the received inquiry to generate the inquiry to be sent, "<user identifier>U001 <specific information> (x ２１ , y ２１ Next, the user transmission unit 34 transmits the inquiry to the information processing device 1.

[0275] Next, the inquiry receiving unit 122 of the information processing device 1 receives an inquiry from the user terminal 3, “<user identifier> U001 <specific information> (x ２１ , y ２１ ) is received.

[0276] Next, the terminal determination means 1311 determines the specific information (x ２１ , y ２１ The terminal determination unit 1311 acquires the specific information (x ２１ , y ２１ ) and the set of location identifiers (x ２２ , y ２２ ) (x ２３ , y ２３ ) (x ２４ , y ２４ ) from the group management table (FIG. 14). Next, the terminal determination means 1311 obtains each of the four pieces of location information (x ２１ , y ２１ ) (x ２２ , y ２２ ) (x ２３ , y ２３ ) (x ２４ , y ２４ ) is determined from the terminal management table (FIG. 15). ２１ , y ２１ ) (x ２２ , y ２２ ) (x ２３ , y ２３) (x ２４ , y ２４ ) are the location information of supermarket A, supermarket B, supermarket C, and supermarket D, respectively. Also, it is assumed that terminal determination means 1311 has acquired terminal identifier "T001" of mobile terminal 2 located in supermarket A, terminal identifier "T002" of mobile terminal 2 located in supermarket B, terminal identifier "T003" of mobile terminal 2 located in supermarket C, and terminal identifier "T004" of mobile terminal 2 located in supermarket D from the terminal management table (FIG. 15). Next, instruction sending means 1312 sends a transmission instruction to each of the four mobile terminals 2.

[0277] Next, each of the four mobile terminals 2 transmits video or the like to the information processing device 1 by the same operation as that described in the first specific example.

[0278] Next, the information processing device 1 receives the video or the like by the same operation as that described in the specific example 1, composes a screen based on the video or the like, and transmits the screen to the user terminal 3.

[0279] Next, the user terminal 3 receives and outputs the screen in the same manner as described in Example 1. An example of such output is shown in FIG.

[0280] (Specific Example 3) It is assumed that a user launches an app on the user terminal 3. The app is capable of acquiring and outputting videos of multiple comparison locations. Next, the app is launched on the user terminal 3. The user terminal 3 then outputs a screen for inputting specific information. Note that this screen has a field for inputting specific information and a "send" button. The "send" button is a button for sending an inquiry to the information processing device 1.

[0281] Next, the user inputs specific information "U101" into the screen and selects the "Send" button. Note that the specific information "U101" is a user identifier.

[0282] Then, the user receiving unit 32 of the user terminal 3 receives the inquiry "<specific information> U101". Next, the user transmitting unit 34 transmits the inquiry "<specific information> U101" to the information processing device 1. Note that the inquiry may include "<user identifier> U101".

[0283] Next, the inquiry receiving unit 122 of the information processing device 1 receives the inquiry “<specific information> U101” from the user terminal 3 .

[0284] Next, the terminal determination means 1311 acquires the specific information "U101" contained in the received inquiry. The terminal determination means 1311 acquires the location identifier set "Supermarket A, Supermarket B, Supermarket C, Supermarket D" that pairs with the specific information "U101" from the group management table (FIG. 14). Next, the terminal determination means 1311 acquires the location information of "Supermarket A, Supermarket B, Supermarket C, Supermarket D" by referring to the map information in the storage unit 11. The location information of each of these four supermarkets is (x ２１ , y ２１ ) (x ２２ , y ２２ ) (x ２３ , y ２３ ) (x ２４ , y ２４ ). Next, the terminal determination means 1311 determines the location information of the mobile terminal 2 (located in the supermarket) that satisfies the location condition for the location information of each of the four supermarkets from the terminal management table (FIG. 15). Here, it is assumed that the terminal determination means 1311 has acquired the terminal identifier "T001" of the mobile terminal 2 located in supermarket A, the terminal identifier "T002" of the mobile terminal 2 located in supermarket B, the terminal identifier "T003" of the mobile terminal 2 located in supermarket C, and the terminal identifier "T004" of the mobile terminal 2 located in supermarket D from the terminal management table (FIG. 15).

[0285] Next, the instruction sending means 1312 acquires the terminal communication information paired with each of the acquired four terminal identifiers from the terminal management table (FIG. 15). Next, the instruction sending means 1312 transmits a transmission instruction to the mobile terminal 2, which is the communication destination indicated by each of the four pieces of terminal communication information.

[0286] Next, each of the four mobile terminals 2 transmits video or the like to the information processing device 1 by the same operation as that described in the first specific example.

[0287] Next, the information processing device 1 receives the video or the like by the same operation as that described in the specific example 1, composes a screen based on the video or the like, and transmits the screen to the user terminal 3.

[0288] Next, the user terminal 3 receives and outputs the screen in the same manner as described in Example 1. An example of such output is shown in FIG.

[0289] (Specific Example 4) In specific example 4, the terminal management table ( FIG. 15 ) manages terminal information including location information transmitted from a mobile terminal 2 mounted on an automobile. The mobile terminal 2 is, for example, a drive recorder or a navigation terminal.

[0290] It is assumed that the user, while driving a car, passes a point just before the junction between the outbound Tomei Expressway and the outbound Shin-Tomei Expressway. Then, the location acquisition unit 331 of the user terminal 3, which is the navigation terminal of the car, acquires the location information (x ３１ , y ３１ ) has been acquired. Next, the query acquisition unit 332 determines that the location information satisfies a predetermined condition with respect to the location information for constructing a query stored in the user storage unit 31 (for example, matches, or the distance is within a threshold).
