Embodiment 1

[0057] In a specific embodiment of the invention, figure 1 It is a schematic flowchart of the first realization of the location information concealment method in the embodiment of the present invention. Such as figure 1 As shown, the concealment method of location information may include the following steps:

[0058] Step 101. After receiving the current query request for the target user, obtain the real location information of the target user and the false location information fed back by the last query request for the target user.

[0059] In the specific implementation of the present invention, the location server first receives the current query request for the target user; wherein, the current query request may carry the location identifier of the target user. In a specific embodiment of the present invention, the location server may store the false location information of the target user corresponding to each query. Therefore, after receiving the current query request...

Embodiment 2

[0087] Image 6 It is a schematic flowchart of the second implementation of the location information concealment method in the embodiment of the present invention. Such as Image 6 As shown, the concealment method of location information may include the following steps:

[0088] Step 601. After receiving the current query request for the target user, obtain the real location information of the target user and the false location information fed back by the last query request for the target user.

[0089] In the specific implementation of the present invention, the location server receives the current location request sent by the inquiring user; wherein, the current inquiring request may carry the location identifier of the target user. In a specific embodiment of the present invention, the query user and the target user may be the same user or different users.

[0090] Step 602. Record the current query time when the current query request is received.

[0091] In a specific...

Embodiment 3

[0121] Figure 11 It is a schematic structural diagram of the first component of the location server in the embodiment of the present invention. Such as Figure 11 As shown, the location server includes: an acquisition unit 1101 and a concealment unit 1102; wherein,

[0122] The obtaining unit 1101 is configured to obtain the real location information of the target user after receiving the current query request for the target user, and the false location information fed back by the last query request for the target user;

[0123] The concealment unit 1102 is configured to conceal the real location information through the false location information when the false location information satisfies a preset anonymity condition.

[0124] Figure 12 It is a schematic diagram of the second component structure of the location server in the embodiment of the present invention. Such as Figure 12 As shown, the concealment unit 1102 includes: a determination subunit 11021 and a concea...

Abstract

The embodiment of the invention discloses a position information hiding method and a position server. The method comprises the following steps: after receiving a current query request aiming at a target user, acquiring real position information of the target user, and false position information fed back aiming at last query request of the target user; and when the false position information satisfies a preset anonymity condition, hiding the real position information through the false position information.

Description

technical field [0001] The invention relates to the field of location services, in particular to an anonymity method based on location information and a location server. Background technique [0002] With the popularization of smart mobile terminals and the development of network technology, operators can obtain location information through signaling data, business application systems, their own positioning platforms and user online logs. Mobile Location-Based Services (LBS), as an important part of mobile communication value-added services, has gradually become an indispensable part of people's lives. Users can use portable mobile devices, such as mobile phones, PDAs, Palms, etc. , to query all kinds of required location information, so that important information such as the user's intention, activity pattern, and potential hobbies can be continuously mined from these location information. However, the threat of privacy leakage caused by location information leakage is als...
