Carleton University - School of Computer Science Undergraduate Honours Project Winter 2011 Using Spatial Cloaking Algorithm to Protect Location Privacy Jing Li 
ABSTRACT When using location-based services (LBS), a Spatial Cloaking Algorithm has been proposed to protect mobile users privacy. Spatial Cloaking is used to blur a users exact location into a spatial region. For example, when a mobile user asks for the nearest gas station, he has to report his exact location. This could lead to location privacy threats. This paper will discuss how to create an anonymous location when using Spatial Cloaking Algorithm. In addition, both centralized and decentralized Spatial Cloaking Algorithms will be discussed for creating an anonymous location. Also, searching for the nearest neighbour before the creation of the anonymous location will be introduced. This paper will then talk about privacy threats through location information. |
