3DLoc2: Three Dimensional Localization and Locking Toolkits for Tracing Anonymous Wireless Criminals

Network forensics plays a crucial role for public safety and homeland security. A critical challenge, however, is the fact that criminals may leverage the open wireless networks provided by many hotels, restaurants, libraries, etc to hide their physical locations even when their network identities are revealed. Motivated by the pressing need of law enforcement officers on locating criminals in urban environments, the authors present 3DLoc2: an integrated system of hardware and software toolkits for locating and locking an 802.11-compliant mobile device in a Three Dimensional (3D) space.
