Embodiment 1

[0059] Example 1, as figure 1 As shown, a customizable location privacy protection method based on user portraits aims to realize customized dynamic protection of user location data, solve the problem of the leakage of user sensitive location information that cannot be effectively solved in the actual location social network environment, and improve the user's personalized experience. At the same time, the Merkle hash tree is used to ensure that the location data is not tampered with during the transmission process, which improves the reliability and controllability of the system. The specific steps are as follows:

[0060] Step 1: Build a decentralized communication network that physically isolates the user's location from the location server; four types of nodes are involved in the process of user location data transmission: user node, relay node, miner node and server. like image 3 The specific process is as follows: the user first broadcasts the network communication r...

Embodiment 2

[0092] Embodiment 2, a customizable location privacy protection system based on user portrait, including a decentralized communication network module, a stop point detection module, a user basic attribute portrait module, a user curiosity intensity portrait module, a server recommendation privacy protection intensity module and Dynamic adjustment module on the local side.

[0093] The decentralized communication network module is used to physically isolate the user's location from the location server;

[0094] The stop point detection module is used to obtain the stop point position in the user's movement trajectory;

[0095] The user basic attribute portrait module is used to extract the basic attributes of the user;

[0096] The user curiosity intensity profile module is used to extract the user's personalized curiosity intensity;

[0097] The server recommending privacy protection strength module is used for the location server to recommend privacy protection strength for...

Abstract

The invention provides a customizable position privacy protection method and system based on a user portrait, and the method comprises the steps: firstly, constructing a decentralized communication network, obtaining the position of a stay point in a movement track of a user, and querying the semantic information of the position from a position server through the decentralized communication network; secondly, portraying the user from two aspects of basic attributes and psychological characteristics of the user, and quantifying privacy requirements of the user through the characteristics of the user; and finally, according to the privacy demand of the user, the position server carries out privacy intensity recommendation on the user, and the local end carries out personalized dynamic adjustment according to the local real-time scene information of the user. According to the method, the customized dynamic protection of the user position data can be realized, the problem that the leakage of sensitive position information of the user cannot be effectively solved in an actual position social network environment is solved, and the personalized experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a customizable location privacy protection method and system based on user portraits. Background technique [0002] The mobile Internet has entered the fifth-generation mobile communication (5G) era. The Internet of Everything 5G network featuring "high speed, high reliability, low latency, and a large number of terminal networks" has greatly changed the way people socialize. In addition, with the continuous popularization of intelligent mobile terminals and high-resolution spatiotemporal data sensors, massive and accurate location data (eg GPS data) are shared by users to the server, and the central server mines through context perception, machine learning, information fusion and other methods. According to the user's behavioral characteristics, according to the differences in the interests of different users or the preferences of the same user in different environ...
