  Abstract

In modern society, location information can be used in a variety of ways, such as inferring products desired by consumers in daily life, preventing collisions in tunnels and construction sites, and preventing the spread of infectious diseases. Although GPS(global positioning system) is widely used as a method of obtaining location information, there is a problem that it does not operate in shaded areas such as indoors and has a large error. In addition, GPS information is unreliable because a user can intentionally manipulate it. Therefore, in this paper, we propose and implement a monitoring system that measures location in an indoor/outdoor integrated environment with GPS and UWB(ultra-wide band) and prevents manipulation of location records using blockchain. To verify the performance, the distance is measured in indoor and outdoor environments, GPS errors are supplemented with UWB, and location information is monitored on the server computer and converted to blockchain and stored.
