With the rapid maturity and development of positioning technology, location-based service (LBS) has become an indispensable part of many industries in social life and national economy, including transportation, social platforms, medical fields, military National defense, etc. With the rapid promotion of wireless network technology and the continuous enrichment of related application fields, LBS has become more complete and convenient, and has a wide range of application prospects. LBS refers to providing location-related services to users through location sharing. In the traditional centralized management mode, problems such as location privacy leakage and location information tampering caused by third parties have brought huge security risks to users. Taking into account the distributed data storage method of the blockchain and the characteristics of openness and autonomy, this paper uses the blockchain to realize the decentralized storage of location information, and on this basis, research and design the location of multi-level privacy protection. The sharing scheme eliminates the security problems caused by third parties and realizes the security of user location information shared.
