At present, LBS privacy protection algorithm cannot be widely used because of its vulnerability in the face of continuous attacks. Therefore, this paper proposes a new location service privacy protection method. The algorithm broadcasts its own location information according to the change of user speed. Then, based on the regional similarity partition algorithm and user balance partition algorithm, the search of k-1 peer nodes is realized by using the imprecise location response mechanism. It enables the location service provider to generate multiple indistinguishable location data, to protect the real location information of location service users. Finally, it is tested on MATLAB platform. The experimental results show that compared with the traditional privacy location protection algorithm, the improved LBS privacy protection algorithm can protect user location information and has better comprehensive performance.
