It is an information processing device to be provided, and is realized by a server device, a cloud system, a beacon, or the like.

The information processing device 100 may be an information processing device that provides some kind of web service to the terminal device 10 of the user U online. For example, the information processing apparatus 100 provides, as Web services, Internet connection, search service, SNS (Social Networking Service), electronic commerce, electronic payment, online game, online banking, online trading, accommodation/ticket reservation, video/music distribution, Services such as news, maps, route search, route guidance, route information, operation information, and weather forecast may be provided. In practice, the information processing apparatus 100 may cooperate with various servers that provide web services as described above, mediate the web services, or take charge of the processing of the web services.

The information processing device 100 can acquire user information about the user U. FIG. For example, the information processing apparatus 100 acquires information about attributes of the user U, such as the user's U gender, age, and area of residence. The information processing apparatus 100 stores and manages identification information indicating the user U (user ID, etc.) and information related to the attribute of the user U. FIG.

The information processing apparatus 100 acquires various types of history information (log data) indicating actions of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. For example, the information processing apparatus 100 acquires a location history, which is a history of the user U's location and date and time, from the terminal device 10 . The information processing apparatus 100 also acquires a search history, which is a history of search queries input by the user U, from a search server (search engine). The information processing apparatus 100 also acquires a viewing history, which is a history of content viewed by the user U, from the content server. The information processing device 100 also acquires a purchase history (payment history), which is a history of product purchases and payment processing of the user U, from an electronic commerce server or a payment processing server. Further, the information processing apparatus 100 may acquire the exhibition history and sales history, which are the history of the user U's exhibition in the marketplace, from the electronic commerce server or the settlement server. In addition, the information processing apparatus 100 acquires the posting history, which is the posting history of the user U, from a posting server that provides a word-of-mouth posting service or an SNS server.

In the present embodiment, as shown in FIG. 1, the information processing apparatus 100 uses a positioning method such as GPS (Global Positioning System) or RTK (Real Time Kinematic) to receive information from the user UA from the terminal device 10A of the user UA. The location information of the visited predetermined area is acquired (step S1). The information processing device 100 acquires provided information related to the acquired location information from the terminal device 10A of the user UA by the same positioning method (step S2). Note that the predetermined area is not limited to position information.

Note that the information processing apparatus 100 is not limited to acquiring the position information and the provided information by the positioning method described above. For example, the user UA uses the terminal device 10A to obtain positional information of a predetermined area visited by the user UA and provided information regarding the positional information, and the information processing device 100 receives information provided from the terminal device 10A of the user UA. The location information and the provision information of the specified area may be acquired.

Subsequently, the information processing device 100 associates and stores the position information of the predetermined area and the provided information acquired from the terminal device 10A (step S3). That is, the information processing apparatus 100 stores the position information of the predetermined area as the provision information. Then, the information processing apparatus 100 attenuates the provided information stored in association with the positional information of the predetermined area over time (step S4). In this case, the information processing apparatus 100 at least reduces the amount or quality of the provided information.

Further, the information processing apparatus 100 acquires the position information of the predetermined area visited by the user UB from the terminal device 10B of the user UB different from the user UA by the positioning method described above (step S11). The information processing device 100 acquires provided information related to the acquired location information from the terminal device 10B of the user UB by the same positioning method (step S12). Note that the predetermined area is not limited to position information.

Note that the information processing apparatus 100 is not limited to acquiring the position information and the provided information by the positioning method described above. For example, the user UB uses the terminal device 10B to obtain the position information of the predetermined area visited by the user UB and the provided information about the position information, and the information processing device 100 receives the information provided from the terminal device 10B of the user UB. The location information and the provision information of the specified area may be acquired.

Here, the information processing apparatus 100 estimates the degree of matching between the stored positional information of the predetermined area and the positional information of the predetermined area visited by the new user UB (step S13). In this case, the information processing apparatus 100 determines whether or not the degree of matching is greater than or equal to a preset first determination value. The information processing apparatus 100 determines whether the degree of matching between the stored position information of the predetermined area and the position information of the predetermined area visited by the new user UB is, for example, 80% or more, which is the first determination value. determine whether

The information processing apparatus 100 also estimates the degree of association between the stored positional information of the predetermined area and the positional information of the predetermined area visited by the new user UB (step S14). In this case, the information processing apparatus 100 determines whether or not the degree of association is greater than or equal to a second determination value lower than a preset first determination value. The information processing apparatus 100 determines whether the degree of association between the stored position information of the predetermined area and the position information of the predetermined area visited by the new user UB is, for example, 60% or more, which is the second determination value. determine whether

When the information processing apparatus 100 determines that the degree of matching (degree of association) is not equal to or greater than 60%, which is the second determination value, for example, similar to the processing of the user UA, the position of the predetermined area acquired from the terminal device 10B is determined. The information and the provided information are associated and stored (step S3). That is, since the positional information of the predetermined area acquired from the terminal device 10A of the user UA is different from the positional information of the predetermined region acquired from the terminal device 10B of the user UB, the positional information of the predetermined region acquired from the terminal device 10A is Separately from the providing place information associated with the position information, it is stored as the providing place information associated with the position information of the predetermined area acquired from the terminal device 10B. Then, the information processing apparatus 100 attenuates the provided information stored in association with the position information of the predetermined area over time (step S4).

On the other hand, when the information processing apparatus 100 determines that the degree of matching (degree of association) is, for example, 80% or more, which is the first determination value, the predetermined area stored in the attenuated state for the user UB Attenuation information associated with the location information is provided to the terminal device 10B of the user UB (step S15). In this case, the information processing apparatus 100 provides provision information to the user UB according to the estimated degree of matching. For example, the information processing apparatus 100 provides more information to the user UB as the degree of matching is higher.

At this time, when the information processing apparatus 100 determines that the degree of matching is, for example, 80% or more, based on the provided information associated with the position information of the predetermined area acquired from the terminal device 10B of the user UB, the stored Provided information associated with the location information of the predetermined area is updated (step S16).

At this time, when the user UA who acquired the stored provided information matches the user UA who newly visited the stored predetermined area, the information processing apparatus 100 newly visited the stored provided information. It is updated by replacing with the information provided by the user UA.

Further, when the user UA who acquired the stored provided information does not match the user UB who newly visited the stored predetermined area, the information processing apparatus 100 determines whether the stored provided information is used by the newly visited user UB. Synthesize and update so as to add the information provided by the person UB.

Further, when the stored provided information and the provided information of the user UB who has newly visited the stored predetermined area are in the same field, the information processing apparatus 100 sets the provided information associated with the stored predetermined area. is updated by adding the information of the user UB who newly visited the predetermined area.

Further, when the information processing apparatus 100 determines that the degree of matching (relevance) is, for example, the second determination value of 60% or more instead of the first determination value of 80% or more, the stored predetermined region is associated with the position information of the predetermined area visited by the new user UB, it is determined that the predetermined area visited by the new user UB is a related area. Therefore, the information processing apparatus 100 associates the predetermined area, the related area, and the attenuation information, and provides them to the terminal device 10B of the user UB (step S17).

At this time, if the information processing apparatus 100 determines that the degree of association is, for example, less than 80% and greater than or equal to 60%, the position information of the predetermined area acquired from the terminal device 10B of the user UB is added to the related area. Position information is added, and provided information is associated and stored (step S18).

After that, the information processing apparatus 100 acquires the position information of the predetermined area visited by the user UC from the terminal device 10C of the user UC other than the users UA and UB, using the positioning method described above (step S21). . The information processing apparatus 100 acquires provision information related to the acquired position information from the terminal device 10C of the user UC by the same positioning method (step S22). At this time, in the same manner as described above, the information processing apparatus 100 determines the degree of matching (relevance) between the stored position information of the predetermined area (related area) and the position information of the predetermined area visited by the new user UC. Estimate (step S13/step S14). Here, if the stored location information of the predetermined area and the location information of the predetermined area visited by the user UC match, the attenuation information associated with the location information of the predetermined area is provided. If so, attenuation information associated with the location information of the predetermined area and the location information of the related area is provided (step S23).

As described above, in the present embodiment, the information processing apparatus 100 acquires the positional information and the provided information of the predetermined area, attenuates the provided information associated with the positional information with the lapse of time, and makes it possible for the user to visit the predetermined area. provide attenuated attenuation information to the

Further, in the present embodiment, the information processing apparatus 100 acquires the position information and the provided information of the predetermined area, stores the provided information in association with the predetermined area, and stores the information for the user who visits the predetermined area. When a user visits a related area related to the predetermined area, the information is stored in association with the predetermined area and the related area.

Therefore, information can be safely shared and managed without setting an access control policy.

[1-2. Outline of information processing method]
An example of a service realized by the information processing described above will be described below. Note that such a service may be realized by the information processing apparatus 100 alone, or may be realized by the cooperation of a plurality of server devices and terminal devices. Further, the following services may be provided not only by the information processing described above but also by the functional configuration described later. Also, the following services may be executed in combination as appropriate. In the following example, as an example of the service, an example of providing information on the user UA to the user UB will be described.

[1-3. Overview of information provision]
For example, when the user UA visits a predetermined place such as in front of a ticket gate at a station or on a mountain road, the information processing device 100 acquires information on the user UA from the terminal device 10A. For example, when it is estimated that the terminal device 10A has visited a predetermined location using a technology such as a geofence, the terminal device 10A sends information about the user UA, that is, provided information and information indicating the location, to the information processing device 100. and send. For example, the terminal device 10A sends provided information such as "user UA was here" and position information indicating the ticket gate position of A station (hereinafter referred to as "place A") to the information processing device 100. Send to

In such a case, the information processing apparatus 100 regards the received provided information as a virtual lingering scent (that is, a virtual scent) of the user UA by the above-described information processing, and uses the provided information for other uses. provided to persons. For example, when the user UB visits the place A after the user UA, the information processing apparatus 100 links the provided information of the user UA (hereinafter referred to as "provided information A"). When the position information of the place A is received from the terminal device 10B, the provided information A is transmitted to the user UB as if the user UB perceives the lingering scent of the user UA. For example, when the user UB visits the place A, the information processing device 100 transmits the provided information A linked to the place A to the terminal device 10B of the user UB.

Here, the information processing device 100 transmits the provided information A using the smell as a metaphor. For example, the information processing apparatus 100 compares the location A associated with the provided information A with the current location of the user UB, and when the user UB is within a predetermined range from the location A, the provided information A may be provided. Further, the information processing apparatus 100 may provide information obtained by processing the provided information A in a manner according to the distance from the place A. For example, the information processing apparatus 100 may provide a range corresponding to the distance from the place A in the provided information A. FIG. More specifically, when the user UB approaches within 10 meters from the place A, the information processing apparatus 100 distributes half of the provided information A to the user UB, and the user UB is 1 meter away from the place A. If it approaches within the time limit, the entire provided information A may be distributed.

Further, the information processing apparatus 100 may adjust the accuracy of the content indicated by the provided information A. FIG. For example, when the provided information A is the information "I drank tea at 10 o'clock", the information processing apparatus 100 determines the accuracy of the content of the provided information A when the user UB approaches within 10 meters from the place A. (granularity) information (for example, information such as "I had a drink in the morning") is generated, and this information is distributed to the user UB. Then, when the user UB moves within 1 meter from the place A, the information processing apparatus 100 may provide highly accurate information such as "I drank tea at 10 o'clock." In the example described above, an example of providing information in two stages has been described, but the information processing apparatus 100 may provide information whose accuracy (granularity) is adjusted in any stage.

Note that the information processing apparatus 100 may provide information whose accuracy (granularity) is arbitrarily adjusted. For example, when the provided information A includes a store name, the information processing apparatus 100 may specify the country, prefecture, and city where the store is located, and distribute information replaced with the specified information. For example, as the information processing device 100 gets closer to the place A, the information processing device 100 “visited a store in Japan”, “visited a store in Saitama Prefecture”, “visited a store in Kawaguchi City”, You may distribute the information which improved the precision of a place step by step, such as "I visited." In addition to the place, the information processing device 100 gradually adjusts the accuracy (granularity) of arbitrary information such as time, position, transaction target category, user behavior, etc., so that the user UB approaches the place A. The more accurately (granularity) the information should be provided. Such information processing can be realized by an information processing technique or the like using a dictionary set in advance.

In addition, the information processing apparatus 100 changes the provision mode of the provided information A according to the time that has passed since the user UA visited the place A, the time that has passed since the place A and the provided information A are linked, and the like. may be changed. For example, an odor in a certain place diffuses over time and becomes less odorous. Therefore, the information processing apparatus 100 may reduce the accuracy (granularity) of the information according to the time elapsed since the user UA visited the place A (hereinafter referred to as "elapsed time"). Further, for example, the information processing apparatus 100 may reduce the accuracy of the provided information A while increasing the range of providing the provided information A as the elapsed time elapses. To give a more specific example, the information processing apparatus 100 may reduce the accuracy and granularity of the provided information A as the elapsed time elapses even within 1 meter from the place A. Further, the information processing apparatus 100 distributes the provided information A to the user UB when the user UB approaches within a radius of 10 meters from the place A within a predetermined period after the user UA visits the place A. However, after a predetermined period of time, when the user UB approaches within a radius of 15 meters from the place A, the provided information A may be delivered to the user UB. In such a case, provision information A with reduced accuracy may be distributed to user UB. On the other hand, the information processing apparatus 100 may narrow the range in which the provided information A is provided as the elapsed time elapses.

Here, when the odor diffuses, the direction of flow changes according to the wind. Therefore, when the information processing apparatus 100 changes (extends) the range in which the provided information A is provided (hereinafter sometimes referred to as the “provided range”) according to the elapsed time, the information processing apparatus 100 may change (extend) it on a concentric circle. However, it may be changed with directivity in a predetermined direction. For example, the information processing apparatus 100 expands the range in which the provided information A is provided in a predetermined direction, such as the west direction or the east direction of the place A, and does not expand in other directions, or does not expand the range in other directions. may also be extended later. Further, the information processing apparatus 100 may provide the provided information A as it is for a predetermined direction, and provide the provided information A with reduced accuracy for other directions.

It should be noted that the direction in which such a provision range is expanded may be determined manually (for example, by the user UA) in advance, or may be determined automatically according to arbitrary rules. For example, the information processing apparatus 100 may expand the provision range in the movement direction of the user A when visiting the place A. Further, the information processing apparatus 100 may extend the provision range in a direction according to the attribute of the user A or the contents of the provision information A. FIG.

Further, for example, the information processing apparatus 100 may change the provision range according to weather information such as the temperature and wind direction at the point A, the number of people at the point A, the direction of the flow of people, and the like. In addition, the information processing apparatus 100 can determine the number of posted information having content corresponding to the provided information A on the SNS, the number of posted information corresponding to the point A, the number of posted information corresponding to the point A, the number of similar search queries, the number of similar search queries, and the like. Depending on the situation, the scope of provision may be changed. That is, the information processing apparatus 100 may change the provision range according to various external factors regarding the point A. FIG.

It should be noted that the accuracy (granularity) in providing the provision information A described above, expansion and contraction of the provision range, and the like may be combined in an arbitrary manner. Further, the accuracy (granularity) in providing such provision information A, expansion or reduction of the provision range, and the like may be changed according to various user settings, or may be changed automatically. Further, for example, the information processing apparatus 100 may appropriately change the accuracy (granularity) to be provided according to the attributes of the user A and the type of the provided information A. For example, the information processing apparatus 100 may prevent the accuracy (granularity) from being lowered as the user A is younger. Further, for example, the information processing apparatus 100 may reduce the accuracy (granularity) depending on whether the provided information A is information related to the user A, other information, information about when For example, the speed or amount at which the accuracy (granularity) is reduced may be changed according to the elapsed time or the distance from the point A. In this manner, the information processing apparatus 100 may increase or decrease information.

The terminal device 10A may transmit information preset by the user UA, or may transmit information automatically obtained. Further, when the information processing apparatus 100 determines that the user UA has visited a predetermined location based on the location information received from the terminal device 10A, the information processing apparatus 100 detects, for example, a search history, a purchase interest history, a Various types of information related to the user UA, such as posted information, may be acquired as the provided information. Further, when the information processing apparatus 100 associates the provided information A with the location A and a predetermined period (a period set in advance, a period set based on the contents thereof, an attribute of the user UA, etc.) has passed, may cancel the distribution of the provided information A.

[1-4. Information of multiple users]
Here, the information processing apparatus 100 may associate information of a plurality of users who have visited the place A with the place A as provided information. For example, when users UA and UB visit location A, the information processing apparatus 100 individually associates provided information A of user UA and provided information B of user UB with location A, respectively. The provided information A and the provided information B may be individually provided to the user UC who visited A. At this time, the information processing apparatus 100 may individually set the provision modes of the provided information A and the provided information B (for example, various types of processing according to accuracy (granularity), provision range, and elapsed period).

Further, the information processing apparatus 100 may combine the provided information A and B of the users UA and UB who have visited the place A and provide the combined information to the user UC. For example, when the user UA visits the place A, the information processing apparatus 100 associates the place A with the provided information A. FIG. Subsequently, when the user UB visits the place A, the information processing apparatus 100 generates combined information AB by combining the provided information A and the provided information B linked to the place A. FIG. At the time of such combination, the information processing apparatus 100 sets a weight (a weight smaller than 1) to the provided information A according to the elapsed time since the user A visited the place A. Information AB may be generated. Further, the information processing apparatus 100 may synthesize the information whose accuracy (granularity) is changed and the provided information B according to the elapsed time since the user A visited the place A. Then, when the user UC visits the place A, the information processing apparatus 100 provides the combined information AB to the user UC.

Note that the information processing apparatus 100 may implement enhancement or deterioration (deterioration of accuracy, etc.) of information according to the contents of the provided information A and the provided information B. FIG. For example, when the content of the provided information A and the content of the provided information B have a common portion, the information processing apparatus 100 may set combined information AB that emphasizes the common portion. In addition, even if a predetermined period of time has passed since the provided information A was linked and the accuracy of a certain part of the information is degraded, the information processing apparatus 100 does not allow the content of the provided information B to match that part. If there is a common part, the precision may be restored to the original precision for that part.

Further, the information processing apparatus 100 simply obtains the provided information A with the provided information B when the user B visits the location A after a predetermined period has passed since the provided information A was associated with the location A. May be overwritten.

Note that the information processing apparatus 100 may individually associate the provided information A and B with the location A, and control the provided range in different modes according to the elapsed time. In such a case, the information processing apparatus 100 determines the weight when synthesizing the provided information A and B according to the timing when the user UC visits the place A and the positional relationship between the user UC and the place A. do. For example, the information processing apparatus 100 determines whether or not the user UC is included in each provision range of the provided information A and B, the distance between the place A and the user UC, and the timing when the user UC visits. The provision mode of the provided information A and B may be determined, the combined information AB may be generated by combining the provided information A and B with a weight corresponding to the determined provision mode, and the combined information AB may be distributed.

[1-5. sensitivity metaphor]
Here, the sensitivity when sensing an odor varies depending on the user. Therefore, the information processing apparatus 100 includes attributes of the user to whom the provided information is provided, content of information included in the provided information, and various types of information related to the provided information (hereinafter collectively referred to as "attributes of provided information"). Depending on the situation, the provision mode of the provided information may be varied.

For example, when the information processing apparatus 100 provides the user UB with the provided information A, the information processing apparatus 100 sets the sensitivity to the provided information A of the user UB. For example, the information processing apparatus 100 may set the sensitivity according to the attributes of the user UB (such as demographic attributes and psychographic attributes). Sensitivity may be set accordingly. To give a more specific example, when the provided information A includes information that the user UB prefers, the information processing apparatus 100 sets the sensitivity of the user UB to the provided information A to "100" and sets the provided information If information that user UB prefers is not included in A, user UB's sensitivity to provided information A is set to "50".

Then, the information processing apparatus 100 provides the provided information A with higher accuracy (granularity) of the provided information A as the sensitivity of the user UB to the provided information A is higher. For example, when the user UB's sensitivity to the provided information A is "50" and the distance from the place A is 5 meters, the information processing apparatus 100 provides the provided information A with reduced accuracy, If the user UB's sensitivity to the provided information A is "100" and the distance from the location A is 5 meters, the provided information A may be provided without lowering its accuracy. Further, for example, when the sensitivity of the user UB to the provided information A is "50", the information processing apparatus 100 reduces the accuracy of the provided information A even if the distance from the place A is 1 meter. and the sensitivity of the user UB to the provided information A is "100", even if the distance from the location A is 10 meters, the provided information A can be provided without lowering its accuracy. good.

Similarly, the information processing apparatus 100 may provide the provided information A without lowering its accuracy if the user UB is highly sensitive to the provided information A, even if the elapsed time exceeds the predetermined threshold. good. Further, for example, when the user UB has a high sensitivity to the provided information A, the information processing apparatus 100 can detect the provided information A (or its accuracy) even when the user UB is 100 meters away from the place A. Information that was lost) may be provided. On the other hand, for example, if the sensitivity of user UB to provided information A is low, information processing apparatus 100 may detect provided information A (or information) may be provided.

Further, when the location A is associated with the provided information A and the provided information B, the information processing apparatus 100 determines whether the provided information of the user UC is provided based on the combination of the attribute of the user UC and the attribute of the provided information A. The sensitivity to information A is set, and the sensitivity to provided information B of user UC is set based on the combination of the attribute of user UC and the attribute of provided information B. Then, the information processing apparatus 100 generates combined information AB by combining the provided information A and B based on the sensitivity set individually for each of the provided information A and B, and provides the generated combined information AB to the user UC. You may

Further, the information processing apparatus 100 determines the provided information of the user UB based on the relationship between the attribute of the user UA regarding the provided information A and the attribute of the user UB who is the delivery destination (or candidate thereof) of the provided information A. A sensitivity for A may be set. For example, the information processing apparatus 100 may set the sensitivity regarding the provided information A of the user UB according to the combination of the attributes of the user UA and the attributes of the user UB. For example, when the user UA is a woman in her twenties and the user UB is a woman in her twenties, the information processing apparatus 100 sets the sensitivity with respect to the provided information A of the user UB higher than a predetermined value, If the user UB is a man in his fifties, the sensitivity for the provided information A of the user UB may be set lower than a predetermined value. Further, for example, when the user UA is a woman in her fifties and the user UB is a man in her twenties, the information processing apparatus 100 sets the sensitivity for the provided information A of the user UB lower than the predetermined value. However, if the user UB is a man in his fifties, the sensitivity of the provided information A of the user UB may be set higher than a predetermined value. The information processing apparatus 100 may increase the sensitivity as the attributes of the users UA and UB are more common, but may increase the sensitivity as the attributes of the users UA and UB are less common. . Further, the information processing apparatus 100 may set a predetermined sensitivity for each combination of attributes of the users UA and UB.

Note that the above-mentioned attributes are not limited to the ages and genders exemplified. It is a concept that includes content. Further, the information processing apparatus 100 may set the sensitivity to the provided information A of the user UB according to a combination of the attribute of the user UA, the attribute of the provided information A, and the attribute of the user UB. Further, the information processing apparatus 100 may distribute the provided information A only to the user UB who is connected with the user UA on the SNS, for example.

[1-6. Summary of smell metaphors]
As described above, the information processing apparatus 100 associates information about the user with the location visited by the user as provided information. Then, the information processing apparatus 100, for example, the distance between the user and the place, the attribute of the user, the combination of the attribute of the user regarding the provided information and the attribute of the user to whom the provided information is provided, the attribute of the provided information , the period of time that has elapsed since linking the provided information, the degree of matching between the attributes of the user and the attributes of the provided information, etc., determine the response to provide the provided information.

More specifically, the information processing apparatus 100 performs the various types of processing described above to determine the provision area in which the provision information A is provided, the provision mode of the provision information A according to the distance from the point A, and the user UB for the provision information A. and the like, and depending on the setting result, decides how to provide the provided information A to the user UB (for example, whether to provide it as it is, or to provide it with reduced accuracy, etc.). Then, the information processing apparatus 100 provides the provision information A to the user UB in the determined mode.

When executing the above-described processes, the information processing apparatus 100 may execute all the above-described processes in parallel, or may execute only a part of the processes arbitrarily selected.

Further, the provision mode of the provision information A described above may be set by the user UA or may be set by the user UB. For example, the information processing apparatus 100 may distribute the provided information A only to users with attributes set by the user UA, or distribute the provided information A to users with distance and sensitivity set by the user UA. may Further, the information processing apparatus 100 may gradually extend the provision range in the direction set by the user UA, and may stop distributing the provided information A after the elapsed period set by the user UA has elapsed. good. Further, the information processing apparatus 100 may distribute only the provided information of the attribute set by the user UB to the user UB, and provides the provided information to the user UB based on the sensitivity set by the user UB. You may control the provision mode at the time.

With such various settings, it is possible to realize a service in which, for example, information is provided only to subordinates from a boss, or from a certain user to his followers. Note that, for example, the information processing apparatus 100 notifies a person climbing a mountain (that is, a user with an attribute of “climbing a mountain”) to the information “the summit is dangerous” set in the middle of a mountain road by a person descending a mountain. Alternatively, the range of provision of such provision information may be gradually expanded in the descending direction of the mountain road. When such processing is performed, the information processing apparatus 100 does not convey the information that "the summit is dangerous" to the user who is descending the mountain, but informs the user who is climbing the mountain that "the summit is dangerous". It can provide information that it is dangerous.

In addition, the information processing apparatus 100 can provide different information for, for example, a person heading to the shopping mall from the station and a person heading to the station from the shopping mall. In addition to these, the information processing apparatus 100 also provides other information such as traffic jams, time sales, accidents, suspicious persons, crowds, forest fires, bear appearances, hunted prey information, rockfall information, etc., whose importance decreases with time. In addition, it is possible to distribute information for which freshness and timeliness are important in an appropriate manner. Note that, for example, the information processing apparatus 100 not only gradually decreases the accuracy of the provided information A and gradually narrows the range of provision, but also gradually increases the accuracy over time and gradually narrows the range. For example, the precision may be gradually decreased or the range provided may be gradually decreased at first, but if the remaining time falls below a predetermined threshold, the precision may be restored to the original precision or the range may be increased to the maximum. can be extended to

[1-7. About information transfer]
In addition, the information processing apparatus 100 may propagate the provided information associated with a certain location to another location in response to movement of the user, and may newly associate the information with that location. That is, the information processing apparatus 100 may implement information propagation using the metaphor of the lingering scent.

For example, the information processing apparatus 100 associates the provided information A with the user UB when the user UB visits the point A to which the provided information A is associated. Here, when the user UB visits within a predetermined range from the point A, the information processing apparatus 100 determines whether the attributes of the user UB and the attributes of the provided information A or the attributes of the user UA (or a combination thereof) are predetermined. , whether or not to link the provided information A to the user UB, depending on the sensitivity of the user UB to the provided information A, the time elapsed since the provided information A was linked to the place A, etc. The aspect of the provided information A (for example, the degree of accuracy to be used) when linking it to the user UB may be appropriately controlled. In the following description, information associated with user UB is provided information AB.

Subsequently, the information processing apparatus 100 associates the provided information AB with the place B when the user UB visits the predetermined place B. FIG. At this time, the information processing apparatus 100 may associate the provided information AB with the place B as it is. The accuracy of the provided information AB may be changed according to the attributes of the UB, the attributes of the provided information AB, and the like, and the changed provided information AB may be linked to the location B. Then, the information processing apparatus 100 provides the user UC approaching the place B with the provided information AB. Note that the information processing apparatus 100 may associate combined information ABB obtained by combining the provided information AB and the provided information B of the user B with the place B, for example. At the time of such synthesis, the information processing apparatus 100 generates a may be used to control the weight at the time of synthesis.

Note that, for example, the information processing apparatus 100 may inquire of the user UB whether or not to propagate the provided information A of the location A, and execute the above-described processing when permission is obtained. Further, the information processing apparatus 100 may link the provided information A to a position set or permitted by the user UB.

Further, the information processing apparatus 100 may appropriately link the provided information AB that links the user UB to the route traveled by the user UB. In such a case, the information processing apparatus 100 provides the user UC who has visited the route information traveled by the user UB with the provided information A (or the provided information AB based on the provided information A) originally associated with the location A. will be transmitted. At this time, the information processing apparatus 100 may set the provision range of the provided information AB to be narrower than the provided range of the provided information A. may be shorter than the period for which the Further, the information processing apparatus 100 may link the provided information AB to the user UC.

Further, for example, when the user UB is associated with the provided information AB, the information processing apparatus 100 may provide the provided information AB to the user UC within a predetermined range from the user UB. In other words, even if the user UC has not visited the place A, the information processing apparatus 100 approaches the user UB who has visited the place A so that the user UB can feel the lingering scent of the place A. The provided information A attached (or provided information AB based thereon) may be provided to the user UC. Further, the information processing apparatus 100 may link the provided information AB to the user UC.

Further, when the information processing apparatus 100 provides the user UC who has approached the user UB with the provided information AB, the information processing apparatus 100 provides the user UB with the provided information A linked to the location A. Depending on the distance between UB and user UC, the time elapsed since linking provided information AB to user UB, attributes of user UB, attributes of user UB, attributes of provided information AB, combinations of these, etc. , the accuracy and the like when providing the provided information AB to the user UC may be controlled.

Note that the information processing apparatus 100 may change the provision mode of the provided information AB depending on whether or not the user UB intentionally consented to the provision of the provided information AB. For example, when the user UB intentionally consents to the provision of the provided information AB, the information processing apparatus 100 may lengthen the period during which the accuracy of the provided information AB is deteriorated.
