Fingerprinting RFID Tags with Transfer-of-Ownership Capabilities
Dr. Dale R. Thompson and Dr. Jia Di, Associate Professors of Computer Science and Computer Engineering at the University of Arkansas, have received a $200,000 grant from the National Science Foundation to develop a technology that will re-define the authentication of a passive radio frequency identification (RFID) tag from being something the tag “knows” to being something the tag “is,” like a fingerprint, and to develop new hardware primitives for transferring ownership of the tag by manipulating the fingerprint in a controlled way. The research will lead to secure and private contactless identification and transfer of ownership of objects. See http://rfidsecurity.uark.edu for more details.
Mapping Three-Dimensional Virtual Worlds
Drs. Susan Gauch, John Gauch, and Hiep Luong have received a $200,000 grant from the National Science Foundation for "Mapping Three-Dimensional Virtual Worlds". This new project explores strategies for gathering content from 3D environments and, using that content, will provide a better understanding of how users are utilizing 3D environments and how they might benefit from more accessible, cross-platform search services. Once the virtual world data is gathered, the PIs will explore how frequently content changes in 3D environments and how users utilize linking in virtual worlds as compared to the linkage structures on the Web. In addition, this project will investigate how traffic patterns in 3D environments are related to links, recommendations, and groups.
