Building a Crowdsensing Platform Based on Spatio-Temporal Fencing

In this research, we propose the concept of spatio-temporal fencing, which restricts the time and area of sensing, and construct crowdsensing platform based on this concept. We have focused on convenience and sense of security to address the issue of improving and maintaining collaborator motivation. For requesters who want to implement crowdsensing, defining the contents of a request is a time-consuming task with many items that must be defined. This platform simplifies the definition of the request and makes it easy to use, because the request can be basically defined only by setting the spatio-temporal fencing and the sensor to be used. Spatio-temporal fencing can make it clear to collaborators when and where sensing will take place, and provide sense of security by reducing privacy barriers caused by concerns about data provision and sensing. In this paper, we have designed, implemented, and verified the operation of this platform.
