Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The wide use of intelligent devices brings great convenience to the work and life of people. Based on location services (Location Based Service, LBS), as mobile positioning systems are applied in more and more scenarios and fields, they become an integral part of people's lives. Based on LBS, the functions of map, navigation planning, position sensing and the like are realized, and great convenience is provided for life of people.
However, as the frequency of users using location-based services increases, applications installed by terminals require users to provide their rights to location information. These applications can obtain specific location information of their daily activities from the user's location data. The query information of the user is exposed to the Internet in a large quantity, so that the risk of revealing the private information is increased.
In the prior art, a user cannot autonomously set the positioning authority of an application request, or the user can autonomously set the positioning authority of the application request, but the fuzzy processing of terminal positioning information can only be realized by performing all fuzzy processing on the positions of the user within a certain range to the same position.
In view of this, the present disclosure provides a positioning method, which provides a user with a right to select at a system level, determines a second location different from the first location based on the first location, i.e., the precise location of the terminal when the first application having positioning authority and being started to use the fuzzy positioning function requests positioning information of the terminal, and responds to a first positioning request of the first application based on the second location.
Fig. 1 is a flowchart illustrating a positioning method according to an exemplary embodiment, which is used in a terminal, as shown in fig. 1, and the terminal provides a fuzzy positioning function. The terminal may be, for example, a smart phone, a tablet computer, a wearable device, a PC, or the like. The embodiment of the present disclosure does not limit the kind of the device to which the positioning method is applied. Referring to fig. 1, the positioning method includes the following steps.
In step S101, it is determined that the terminal opens the ambiguous positioning function for the running first application.
In step S102, a first location request is determined for requesting a first location in response to a first application running on the terminal initiating the first location request.
In step S103, a second position different from the first position is determined based on the first position.
In step S104, the first positioning request is responded to based on the second location.
In the embodiment of the disclosure, the terminal starts the fuzzy positioning function for the running first application, which may be a fuzzy positioning function started in a system setting of the terminal, which may be a fuzzy positioning function started for one application or a plurality of applications. And when the first application runs, the fuzzy positioning function is started aiming at the first application in the popped prompt window for authorizing the authority.
The first application initiates a first positioning request to position the first position of the terminal, and the first application is used for requesting to acquire the current positioning position of the terminal. It will be appreciated that the request of the first application is for obtaining the current location of the user, and in general the location of the terminal and the location of the user may be identical, i.e. the current location of the terminal is representative of the current location of the user. The first application may be an application that implements shopping, life service, navigation, etc., and requires location information of a user to provide related services. In the embodiment of the disclosure, the first position is the current position where the user is precisely positioned.
When the user determines that the first application does not have the positioning right, the terminal refuses the request of the first application, and the first application cannot acquire the positioning information of the user. When the first application has positioning authority and is started to use the fuzzy positioning function, the first application cannot acquire the accurate positioning information of the user. Based on the first position, a second position different from the first position is determined, i.e. the second position is a blurred position relative to the first position.
For a first positioning request initiated by a first application, the terminal responds to the first positioning request based on a second position, namely, a second position which is determined based on the first position and is different from the first position when positioning information used by the first application is allowed.
In an embodiment, the fuzzy positioning client sends the first position of the terminal acquired by the system layer to the fuzzy positioning server, the fuzzy positioning server determines a second position different from the first position, and returns the second position to the fuzzy positioning client, and the fuzzy positioning client responds to the first positioning request based on the second position after corresponding processing. It can be appreciated that, in the terminal operating system, when an application requests to acquire positioning information of the system, positioning permission of the system needs to be acquired. The authority setting is performed on the positioning function or the fuzzy positioning function at the system level, namely, the accurate positioning authority required by the autonomous selection application or the fuzzy positioning authority setting is provided for the application at the system level.
According to the embodiment of the disclosure, for the first application with the positioning authority and started to use the fuzzy positioning function, when the first position of the positioning terminal is requested, the second position different from the first position is determined based on the first position, the second position is the fuzzy positioning relative to the first position, and the second position is provided for the first application to use, namely, when the system level provides a choice for a user whether to use the fuzzy positioning or not, the fuzzy positioning is only provided for the application when the application is allowed to acquire the positioning authority, so that the accurate position information of the user is effectively protected, and the privacy protection of the user is realized.

According to the embodiment of the disclosure, for the first application with the positioning authority and started to use the fuzzy positioning function, when the first position of the positioning terminal is requested, the second position different from the first position is determined based on the first position, the second position is the fuzzy positioning relative to the first position, and the second position is provided for the first application to use, namely, when the application is allowed to acquire the positioning authority, the fuzzy positioning is only provided for the application, so that the accurate position information of a user is effectively protected, and the hidden private protection of the user is realized.
Fig. 7a to 7d are application diagrams illustrating a positioning method according to an exemplary embodiment of the present disclosure, and referring to fig. 7a, a positioning authority setting page of a first application is illustrated. In the positioning permission setting page, the first control for allowing the first application to acquire the positioning permission is a selection button below the map preview, and the user can switch the permission condition of the positioning permission based on the operation on the first control according to the need. Such as reject, query, in-use permit, and always permit, etc. When the user's selection is refusal, the user determines that the first application does not have positioning rights.
In the positioning authority setting page of the first application, a second control used for representing the opening of the module positioning function is a floating icon in the map preview image, and a user determines the opening or closing of the first application fuzzy positioning function by operating the second control. When the 'fuzzy positioning' function is closed, the first application can acquire accurate positioning information of the user. When the 'fuzzy positioning' function is closed, the first application can acquire fuzzy positioning information of the user. The position shown in fig. 7a is the exact position of the terminal, i.e. the first position.
Fig. 7b shows that in the positioning authority setting page of the first application, a first control for allowing the first application to acquire the positioning authority is triggered, and a second control for characterizing that the positioning function of the module is opened is triggered, so that it is determined that the first application has the positioning authority and is opened to use the fuzzy positioning function. The position shown in fig. 7b is the first position of the terminal, and it can be seen that the second position is different from the first position, and the application is authorized to use the second position, so that the first position of the accurate position of the user is effectively protected.
Fig. 7c shows that in the positioning authority setting page of the second application, according to the selection of the function option, it is determined that the second application has the positioning authority and is started to use the fuzzy positioning function, and for the same terminal, a second position is provided to the second application to respond to the request of the second application for the first positioning. That is, for the same terminal, the corresponding positioning request is performed at the second location for the different first application and second application which have positioning authority and are opened to use the fuzzy positioning function.
In fig. 7d, "Σ", "Δ" indicates the first and second terminals at the same position, wherein "Σ", "Δ" in dotted lines is the first position of the first and second terminals, i.e. the first position of the first and second terminals. For the first terminal and the second terminal, the first application has positioning authority and is started to use the fuzzy positioning function. A different second location different from the first location is determined for the first terminal and the second terminal, respectively, based on the first location. In the figure, the "o" and "Δ" of the solid line are the second positions of the first terminal and the second terminal, and it is known that, for different terminals at the same position, the response to the positioning request of the application is based on different pieces of fuzzy positioning information.
According to the embodiment of the disclosure, for the first application with the positioning authority and started to use the fuzzy positioning function, when the first position of the positioning terminal is requested, the second position different from the first position is determined based on the first position, the second position is the fuzzy positioning relative to the first position, and the second position is provided for the first application to use, namely, when the application is allowed to acquire the positioning authority, the fuzzy positioning is only provided for the application, so that the accurate position information of a user is effectively protected, and the hidden private protection of the user is realized.
Fig. 8 is a system architecture diagram illustrating an implementation of a positioning method according to an exemplary embodiment of the present disclosure. Referring to fig. 8, a first application running on a terminal applies for location authority, initiates a first location request, and requests to locate a location of the terminal. When the first application has positioning authority and does not start to use the fuzzy positioning function, responding to the first positioning request, and returning the accurate positioning information of the terminal, namely, a first base station to which the terminal belongs at a first position, a first base station identifier and first longitude and latitude information corresponding to the first base station, and the first base station identifier and the first longitude and latitude information.
When the first application has positioning authority and starts to use a fuzzy positioning function, the fuzzy positioning client performs fuzzy processing on the position information of the terminal, and the fuzzy positioning server performs address coding processing on the longitude and latitude in the request through signature verification and replay attack prevention check to generate a corresponding GeoHash, and performs random query in a remote dictionary service cache to determine a second base station identifier based on the GeoHash after the address coding processing. The second base station identifier is a base station identifier randomly selected in the source data based on GeoHash. The source data comprises a base station identifier randomly selected from a plurality of base station identifiers and base station longitude and latitude information. Through data verification, the data is stored in offline storage, namely a distributed file system through a computing engine. Data for a plurality of base stations is provided for remote dictionary service caching. In the query results in the remote dictionary service cache, the base station identifier is different from the base station identifier input in the request, and the query result triples, namely the base station identifier, the base station longitude and the base station latitude, are returned to the fuzzy positioning client. And the fuzzy positioning client returns to the first application applying the position authority after corresponding processing. The fuzzy positioning client can buffer data requested by the terminal, and the same fuzzy positioning information is provided for the same terminal aiming at different applications which have positioning authority and are started to use the fuzzy positioning function.
Based on the same conception, the embodiment of the disclosure also provides a positioning device.
