Abstract

In this study, we summarize the main principles of privacy-aware system and present a new architecture. We preserve the person’s location privacy by using the methods of spatiotemporally-based anonym and location information disturbing. In the spatiotemporally-based anonym method, the space and time are divided into pieces. While, an entity hands over from one domain to another, its ID will be refreshed. In the location information disturbing method, there are two methods to disturb coordinate data. One is transferring coordinate to a random data, the other is transferring coordinate to a fixed data.
