REACT: An RFID-Based Privacy-Preserving Children Tracking Scheme for Large Amusement Parks
In this paper, the authors propose an RFID-based privacy-preserving Children Tracking (REACT) scheme for helping locate missing children in large amusement parks and other public venues. The scheme is characterized by the cooperation among RFID readers, storage nodes and control center, which are strategically deployed across the amusement park, as well as employees and visitors in the park. When a passive RFID tag, physically attached on a child, approaches an RFID reader, the reader will process the tag information. The reader then forwards the information to a storage node through a pocket switched network formed by employees and visitors in the park.
