Research on User Privacy Protection Algorithm in Location Service
Jian-Lan Liu, Zhen Xu, Xin Yi Xu, Zheng Zou · 2020
With the continuous improvement of positioning technology and wireless communication technology, and the rapid spread of smartphones, mobile users can use various types of location-based services anytime, anywhere. At the same time, the privacy issues brought by location services are getting more and more attention from researchers. In order to improve the efficiency of the algorithm and improve the ability to resist attacks, this paper studies the user location privacy protection technology under the mobile peer-to-peer architecture. This paper proposes a location information protection algorithm based on bidirectional active concealment space. The user location privacy protection is implemented by using a dummy location privacy algorithm. The experiment shows that this algorithm can protect the privacy of users in the location service well, and can resist both passive and active attacks, and provide accurate location service at the same time.
