Abstract: A location privacy protection model was proposed based on the central server structure, designed a location privacy protection scheme based on pseudo-random permutation for the model. Proposed scheme builds on k-anonymous and secret information retrieval technology design concept and methods, achieves a blind query and perfect anonymous. This scheme has been proven to have untraceability and unlinkability, and the efficiency is analyzed as well.
