Problems solved by technology

Compared with the permanent authorization, the authorization during the use period has been improved to a certain extent. However, when the mobile application software is still running in the background, the location service provider can still obtain the location information of the mobile phone user, and the location privacy of the mobile phone user is still not reasonably protected.
In addition, the authorized objects of mobile phone users' location information are rather messy. Almost all software applications can initiate a request to obtain location information. If mobile phone users are a little careless, their location information can easily fall into the hands of illegal organizations.

Abstract

The invention discloses a smart phone cloud positioning method based on block chain privacy protection. The steps include: 1. Construction of block chain network; 2. Account registration / login stage and location information protection; 3. Authorization and deauthorization stage; 4, information transmission stage. The invention can effectively prevent the location information of the mobile phone from being arbitrarily obtained by the location service provider, and at the same time ensure the safe transmission of the location information of the mobile phone, thereby protecting the location privacy of the mobile phone user.

Description

technical field [0001] The invention belongs to the technical field of data encryption and location privacy protection, and specifically relates to a smart phone cloud positioning method based on block chain privacy protection. Background technique [0002] With the rapid development of space positioning technology and mobile network, the use of Internet is also changing from fixed devices such as "PC" to mobile devices such as smart phones, and the satellite navigation and location service industry are developing rapidly. As of today, location-based services (Location Based Services, LBS) have been closely related to people's lives. The so-called location-based service means that users obtain their own geographical location through the positioning technology of mobile devices such as smart phones, and location service providers provide users with various location services according to the user's geographical location. Location-based services greatly facilitate people's liv...
