Track data acquisition system and method based on privacy perception

Abstract

The invention discloses a track data acquisition system based on privacy perception, which comprises a user acquisition module, a track generation module, a privacy perception module and a track fuzzyprotection module. The invention also discloses a track data acquisition method based on privacy perception. Through acquiring system user personal information, position information of the user completing personal information acquisition is acquired, the position information is identified, whether the position information is normal position track information or not is judged, features are extracted according to the normal position information, clustering analysis is conducted on the extracted position features, a user track model is generated, perception analysis on user privacy is carried out, a user movement track diagram is generated according to privacy information sensitivity in combination with a user track model, fuzzy processing on a user movement track is carried out according toprivacy perception analysis, and a dynamic track is converted into static data for storage, thereby providing a data acquisition method with high safety and high operability, and providing a good reference basis.

Description

technical field [0001] The invention relates to the technical field of trajectory data collection, in particular to a privacy-aware-based trajectory data collection system and method. Background technique [0002] Privacy awareness is an important condition in the process of privacy protection. With the continuous leakage of social information, the privacy awareness of many personal information including images and trajectory data has become particularly critical. Applying privacy awareness to data collection is mainly to solve the problem of trajectory data. The problem of leakage, but in the existing technology, the arrival of the big data era has brought the value of data collection to a great extent. At the same time, when people collect data, they are concerned about the privacy and security of the data collection process. The security requirements have also been improved accordingly. With the continuous development of science and technology, users have a stronger aware...

Problems solved by technology

[0003] 1. In the existing technology, the collection of user trajectory data does not take into account the dynamics of the user and the uncertainty of the user's movement trajectory, and at the same time brings hidden dangers of privacy leakage to the user, making the data collection system and the collected information lack certainty. security;

[0004] 2. In the existing technical solutions, after the user data is collected, the generated user trajectory has certain errors. In other words, the motion trajectory generated through data collection does not have high accuracy. application effect;
