Problems solved by technology

[0006] At present, there are not many methods with comprehensive location privacy performance. Most methods can only prevent certain types of attacks, and the overall performance is not satisfactory. In areas with strong attack capabilities, the user's location privacy may still be leaked
Moreover, the current approach is basically at the expense of positioning accuracy in exchange for the security of location privacy, and does not consider how to avoid attacks in path planning.

Embodiment 1

[0037] Embodiment 1. A safe path planning method for a mobile terminal, such as figure 1 Shown, including:

[0038] S110. Receive a service request based on the location information of the mobile terminal and forward it to a location-based server LBS, and obtain a response location of the service request from the LBS;

[0039] S120. For multiple pre-divided areas, obtain parameters of each area from the LBS; the parameters include the area size of the area, the number of mobile terminals entering and leaving the area within a predetermined time period, and each mobile terminal in the area at the current moment The customized desired privacy level; the vulnerability assessment value of each area is calculated according to the parameters;

[0040] S130. Calculate a safe path according to the vulnerability assessment value of each area and the response location, and return it to the mobile terminal; the safe path is from the current location of the mobile terminal to the response locati...

Embodiment 2

[0054] Embodiment 2. A secure path planning device for a mobile terminal includes:

[0055] The location obtaining module is configured to receive a service request based on the location information of the mobile terminal and forward it to the location-based server LBS, and obtain the response location of the service request from the LBS;

[0056] The evaluation module is used to obtain the parameters of each area from the LBS for a plurality of pre-divided areas; the parameters include the area size of the area, the number of mobile terminals that enter and leave the area within a predetermined time period, and the current time in the area The expected privacy level customized by each mobile terminal; calculate the vulnerability assessment value of each area according to the parameters;

[0057] The path calculation module is configured to calculate a safe path based on the vulnerability assessment value of each area and the response location, and return it to the mobile terminal; t...

Embodiment 3

[0065] Embodiment 3. A safe path planning system for a mobile terminal includes:

[0066] Location-based servers (LBS), trusted third parties (TTP) and mobile terminals. The functions of the three parts are as follows: the user uses the mobile phone as a mobile terminal to provide services based on geographic location information; TTP is a key part of the system, and the main function is to realize the anonymous operation of the service request submitted by the user and the vulnerability assessment of the system Work and dynamic path planning work; LBS provides services based on geographic location information, such as responding to the geographic location coordinates of the nearest restaurant and sending real-time traffic information.

[0067] The workflow of the entire system can be roughly divided into six steps, the specific steps are as follows:

[0068] ① The user makes a service request based on location information through a mobile terminal, such as finding the nearest hotel...

Abstract

The present invention provides a safe path planning method and device for a mobile terminal; the method includes: receiving a service request based on location information of a mobile terminal and forwarding it to an LBS, and obtaining a response location of the service request from the LBS; for pre-divided A plurality of areas, obtain the parameters of each area from the LBS; calculate the vulnerability evaluation value of each area according to the parameters; calculate the safety path according to the vulnerability evaluation value of each area and the response position, and return to The mobile terminal; the safe path is a path from the current location of the mobile terminal to the response location, and a path with the smallest sum of reciprocals of vulnerability evaluation values ​​of passing areas. The present invention comprehensively considers factors such as communication infrastructure setting, path distribution, and mobile terminal distribution in a specific geographical area, and provides safe, reliable and accurate path planning schemes for mobile users.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for safe path planning of a mobile terminal. Background technique [0002] With the continuous development of positioning technology, mobile communication technology and smart phone platform (mobile terminal platform), service technology based on geographic location information has emerged. This technology can provide mobile users with geographic location information services, and users only rely on vehicle-mounted systems. (Smartphone) You can enjoy geographic information services anytime and anywhere, such as querying the nearest movie theater, querying the shortest route to a park, making friends based on geographic location, etc. Although this kind of service and positioning technology provides great convenience for mobile users, it is necessary to obtain the precise location information of the mobile user before using it. The location-based service sy...
