Description

Information recommendation method and device based on geographic position and electronic equipment

Technical Field

The present application relates to the field of data processing technologies, and in particular, to a method and an apparatus for recommending information based on a geographic location, and an electronic device.

Background

With the rapid development of the information age, people increasingly rely on convenience brought by internet technology, and services based on geographic location information are widely applied to mobile devices, for example, a user device 100 provides a user with a merchant location information service based on a service device 110 shown in fig. 1. However, in some cases, the location information of the user may be leaked, which may cause a safety hazard to the user.

In the prior art, for example, as shown in fig. 1, a user device 100 generally employs a privacy protection apparatus 120 provided by a third party to protect the real location information of a user. Specifically, the privacy protecting apparatus 120 performs fuzzy preprocessing based on the real location information of the user, such as randomly generating a plurality of pieces of virtual location information within a certain threshold range from the real location information, and the privacy protecting apparatus 120 randomly outputs one piece of service location information to the service provider 200 from the real location information and the plurality of pieces of virtual location information. The facilitator 200 provides services to the user based on the service location information, such as providing the user with hotel location information within 100 meters of the vicinity of the location where the user is located. The generation of the number and the position of the virtual position information is random, and when the service position information adopted by the service provider 200 is virtual position information having a large deviation from the real position information, the quality of service provided by the service provider 200 for the user is poor, for example, a hotel recommended by the service provider 200 for the user according to the virtual position information is a hotel near the virtual position, and the virtual position is far from the real position of the user, so that the difference between the hotel information provided by the server 200 for the user according to the virtual position and the hotel information near the real position of the user is large, and the user experience is influenced.

Therefore, how to protect the safety of the real position information of the user and not influence the quality of the service provided for the user based on the position information of the user is a technical problem which needs to be solved urgently.

Detailed Description

Illustrative embodiments of the present application include, but are not limited to, a method, apparatus, product, and electronic device for geographic location based information recommendation. For a better understanding of the present solution, the names referred to in the present application are explained below. According to the technical scheme, the data acquisition, storage, use, processing and the like meet relevant regulations of national laws and regulations.

Fig. 1 is a diagram of an application scenario of a geographic location based information recommendation method, as shown in fig. 1, a user equipment 100 includes a service device 110 and a privacy protecting device 120. Wherein the service device 110 may be a service platform provided by the service provider 200 for the user, such as a service platform providing the location information of the merchant. The privacy protecting apparatus 120 is used to perform privacy protecting processing on real location information of a user that the service apparatus 110 needs to send to the service provider 200.

As described in the background art, in order to generally avoid the disclosure of the geographical location information of the user, the user device 100 used by the user randomly generates a plurality of pieces of virtual location information within a certain threshold range from the real location information of the user by using the privacy protecting apparatus 120 of the third party, and randomly outputs one piece of location information as the service location information from the real location information and the plurality of pieces of virtual location information. When the service location information is virtual location information and the deviation between the real location information and the virtual location information is large, it is easy to cause inaccuracy of the service information provided by the service provider 200 and influence user experience.

For example, assuming that the privacy protecting apparatus 120 generates a location protection range in a two-dimensional space with a real location of the user as a center and a certain threshold range from the real location of the user as a radius, the location protection range includes a plurality of virtual locations and a real location at the center of the location protection range. Each virtual position corresponds to one piece of virtual position information, and the real position corresponds to one piece of real position information. Specifically, the virtual position information and the real position information may be coordinate information.

Specifically, fig. 2 is a schematic diagram of screening virtual location information according to some embodiments of the present application, and referring to fig. 2, a virtual location corresponding to virtual location information Z sent by the user equipment 100 to the service provider 200 is located outside an actual query area RA, and real location information X of a user is located in the actual query area RA. If the randomly output location information is virtual location information Z, and the difference between the location information of the hotel in the actual query area provided by the facilitator 200 based on the virtual location information Z, which is relative to the user (for example, the location of the hotel a is 50 meters in the west direction of the user) and the location information of the hotel, which is relative to the real location of the user (the location of the hotel a is 100 meters in the east direction of the user), is large, the relative location information between the hotel location provided by the facilitator 200 and the user location may be inaccurate, and the user experience may be poor. For example, the hotel location information obtained by the service provider 200 based on the virtual location information Z shows that there is no hotel around, for example, there is no hotel around 100 meters, but it is a real case that the user is a hotel around the real location. For another example, if the hotel location is located between the real location and the virtual location, the user may move 50 meters in the west direction based on the location information of the hotel relative to the user provided by the service provider 200, which is just opposite to the actual required movement direction (e.g., 100 meters in the east direction), and the user may not reach the hotel.

Therefore, the application provides an information recommendation method based on the geographic position, which generates virtual position information in a position protection range based on the real position information of a user; in the case where the real position information and the virtual position information are not located in the actual query area at the same time or are not located outside the actual query area at the same time, the virtual position information is deleted, and one of the real position information and the reserved virtual position information is randomly output as service position information to the server dealer 200. The service provider 200 provides the user with the desired service according to the received service location information.

According to the geographical indistinguishable location privacy protection method provided by the application, on the premise that the real location information security of the user is guaranteed, the generated virtual location information is screened by taking the actual query area as a limiting condition, and the virtual location information which is easy to influence the service quality of the service provider 200 in the location protection range is deleted. That is, when the actual location information is located within the actual query region, the virtual location information within the actual query region is retained, and when the actual location information is located outside the actual query region, the virtual location information outside the actual query region is retained. The quantity and the position of the virtual position information are controllable, so that the deviation between the virtual position information and the real position information is reduced, and the accuracy of the service provider 200 for providing the service for the user is improved. The method and the system avoid that when the real position information and the virtual position information are not located in the actual query area or outside the actual query area at the same time, after the user side sends the virtual position information to the service provider 200, the service provider 200 obtains an error judgment based on the relative position information provided by the service provider 200 when the relative position information between the information such as the merchant position and the user position provided by the virtual position information and the real relative position information between the information and the user position are greatly deviated, and thus the user cannot find the merchant position when judging that a walking route is wrong.

Fig. 3 is a schematic diagram of another filtering of virtual location information according to some embodiments of the present application. For convenience of understanding the technical solution of the present application, a filtering rule of the virtual location information according to the technical solution of the present application is briefly described below with reference to fig. 2 and 3.

In the case where the actual query area RA is within the location protection range RX, as shown in fig. 2, the virtual location information (e.g., virtual location information Z) outside the actual query area RA may be removed, and one of the real location information X and the reserved virtual location information may be randomly output as service location information.

In the case where the real position information X is within the actual inquiry area RA, as shown in fig. 3, it is possible to remove the virtual position information (e.g., the virtual position information Z1) within the overlapping portion and randomly output one from the real position information and the reserved virtual position information as the service position information.

When the real position information X is within the real polling area RA, the virtual position information other than the overlapping portion is removed and one of the real position information X and the reserved virtual position information is randomly output as service position information.

It is to be understood that, with the above-described embodiment, the relative positions of the actual location information X and the actual query area RA are similar to the relative positions of the service location information and the actual query area RA, so that the service provided by the service provider 200 for the user based on the service location information is close to the service provided for the user based on the actual location information X.

The following describes a location privacy protection process in detail with reference to fig. 1 and 2.

Illustratively, referring to fig. 1, the user sends the user's real location information X (shown in fig. 2) and a query target request (1, sending a query target request) to the privacy protecting apparatus 120 through the service apparatus 110, for example, the query target request is hotel location information in the actual query area RA (shown in fig. 2).

Referring to fig. 1, the privacy protecting apparatus 120 performs privacy protection processing on the real location information of the user to obtain service location information, and sends the service location information and the query request to the service provider 200(2, sends the service location information and the query request). Wherein the query request contains a query target of the user and a preset query range RC (RC ═ 5 km as shown in fig. 2) larger than an actual query area RA (RA ═ 0.6 km as shown in fig. 2) of the user. For example, the query target request is hotel location information within a preset query range RC. The service location information may be the user's real location information or the virtual location information Z (shown in fig. 2) generated by the privacy securing means 120.

With continued reference to fig. 1, the facilitator 200 obtains query data based on the service location information and transmits the query data to the privacy securing means 120(3, transmits the query data). For example, the service provider 200 obtains hotel location information within a preset query range RC based on the service location information, and sends the hotel location information within the preset query range RC to the privacy protection apparatus 120.

With continued reference to fig. 1, the privacy securing means 120 transmits the inquiry data to the service means 110(4, transmits the inquiry data). The service device 110 screens the query data for RA in the user's actual query region. For example, the service device 110 screens out the hotel location information in the actual query area RA from the hotel location information. As described above, the hotel location information is location information with respect to the service location information, and therefore, if the virtual location information is too much different from the real location information, the hotel location information is inaccurate. There is therefore a need for improvements in location privacy protection methods.

The geographical location based information recommendation method provided by the present application is further described in detail below with reference to the accompanying drawings.

Fig. 4 shows a flowchart of a method for recommending information based on geographic location, and the information pushing method shown in fig. 4 is described below with reference to fig. 1 to 3.

S401: the privacy securing means 120 receives the user's real location information X and the user's actual query area RA.

Illustratively, the user sends an actual query area RA to 120 through the service device 110, for example, as shown in fig. 2 and 3, RA is a circular area with a point a as a center.

S402: the privacy securing means 120 generates virtual location information within a preset location protection range RX based on the real location information.

In some embodiments of the present application, the user presets the location protection range RX through the privacy protecting apparatus 120, for example, the preset location protection range RX is 1 km. That is, the user needs to protect the user's real location information X within 1 km from the real location.

In some embodiments of the present application, the location protection range RX may be transmitted by the user to the privacy securing device 120 through the service device 100. Therefore, the user can set the position protection range RX by himself based on own requirements, and privacy protection experience of the user is improved.

For example, the privacy protecting apparatus 120 determines the location protection range RX based on the plane laplacian function distribution shown in fig. 5 with the real location information X of the user as a center of a circle, for example, RX is 1 km; since the distribution of the planar laplace function is continuous distribution, in order to ensure the characteristic of the discrete distribution of the virtual position information, the position protection range RX is subjected to discrete processing to obtain all noise points in the position protection range RX, and the projection of each noise point on a two-dimensional plane (a plane formed by an X axis and a Y axis) is one piece of virtual position information.

The above plane laplace function is shown by the following formula (1):

f(X_O)＝f(X)+[lap(Δf/RX)]^d (1)

wherein, f (X)_O) For virtual location information, f (X) for real location information of the user, RX for location protection rangeThe radius d is the distance between the virtual position information and the real position information, Δ f is a sensitivity value, and the larger Δ f is, the larger noise is, that is, the larger the difference between the virtual position information and the real position information is.

As shown in fig. 5, the real position information of the user corresponds to the projection of the tip of the distribution of the planar laplacian function. The noise points formed by the planar laplacian function distribution closer to the tip are denser, that is, the more virtual position information is formed, so that the virtual position information output by the privacy protection device 120 is closer to the real position information, so that the service provider 200 can provide more accurate service information.

For example, the privacy protecting apparatus 120 associates the identity information of the user with the real location information X, the actual query area RA and the location protecting range RX of the user, so as to provide the location privacy protecting service for a plurality of users.

S403: the privacy protecting apparatus 120 screens the virtual location information within the location protecting range RX based on the actual query area RA, to obtain the virtual location information that satisfies the preset location condition.

In some embodiments of the present application, as shown in fig. 2, in the case where the actual query area RA is within the location protection range RX, the virtual location information outside the actual query area RA is removed.

In some embodiments of the present application, in a case where the actual query area RA partially overlaps with the location protection range RX, if the real location information X is within the actual query area RA, the virtual location information outside the overlapping portion is removed; if the real location information X is within the actual query area RA (as shown in fig. 3), the virtual location information within the overlapping portion is removed.

In some embodiments of the present application, new virtual location information is generated at the intersection of the removed virtual location information and the real location information, and the actual query region. For example, after the virtual position information Z shown in fig. 2 is deleted, new virtual position information M is generated at the intersection of the line connecting the virtual position information and the real position information X and the boundary of the actual query area RA. Similarly, after the virtual position information Z1 shown in fig. 3 is deleted, new virtual position information M1 is generated. Therefore, the problem of insufficient privacy protection degree caused by uneven distribution of the virtual position information is solved.

Illustratively, the virtual position information Z shown in fig. 2 may be deleted by first cleaning the noise points. For example, RA and RX in fig. 5 are schematic diagrams of the actual query area RA and the location protection range RX in the plane laplacian function shown in fig. 2, respectively, and delete the noise point corresponding to the virtual location information Z to generate a noise point corresponding to the new virtual location information M.

Through the embodiment, the relative positions of the real position information X and the actual query area RA are approximate to the relative positions of the service position information and the actual query area RA, and meanwhile, the real position information of the user is protected.

S404: the privacy securing means 120 randomly outputs one of the real location information and the virtual location information satisfying the preset location condition as the service location information by a random function.

Illustratively, the random function is the plane laplacian distribution function, and when the real position is input, the probability that the position information output by the plane laplacian distribution function is the real position information and the virtual position information is the same.

S405: the privacy securing means 120 transmits the service location information to the facilitator 200.

With the above-described embodiment, the relative positions of the real location information X and the actual query area RA are similar to the relative positions of the service location information and the actual query area RA, so that the service provided by the service provider 200 for the user based on the service location information is close to the service provided for the user based on the real location information X.
