| 英文摘要 | Location-based service(LBS) has brought convenience to users' lives, but there is also a risk of disclosure of location track privacy. How to protect these private data has become a research hotspot. This paper introduced the system architecture of existing privacy protection methods, summarized the location privacy protection technology and trajectory privacy protection technology, classify expound the privacy protection methods based on distortion technology, encryption technology, anonymity technology and differential privacy technology and sorted out the latest algorithms under various privacy protection technologies. According to the understanding of the existing technologies, it put forward the shortcomings in the present research and the future research direction. |
