Location-aware and privacy-preserving approach for child-care and safety in ubiquitous computing environment

In this paper, we establish our system model over the sensor network addressing contradictory issue caused by mutual authentication and privacy protection of an end-user. Based on the system model, we propose the protocol for a location-aware and privacy-preserving approach for child-care and safety over wireless sensor networks. Although we illustrate our protocol over the sensor network, our protocol can be operated over various networks (e.g., WiFi and UWB) which can provide RSSI (Received Signal Strength Indication). Compared to previous work, our protocol can enhance the accuracy of location information, preserve privacy of an enduser, and give the capability of controlling the child-care and safety service to an end-user. key words: Privacy protection, location supporting protocol, ubiquitous, child-care
