  • SYSTEM AND METHOD FOR SECURING LOST TERMINAL USING WIRELESS NETWORK
    Publication number: 20120172039
    Abstract: A system and method for securing a lost terminal using a wireless network are provided. The system includes a lost terminal registration server to store unique terminal information of a lost terminal, and a terminal including a wireless Local Area Network (LAN) module to connect to the lost terminal registration server to determine whether the terminal is registered as a lost terminal in the lost terminal registration server. If the terminal is determined to be a lost terminal, then the lost terminal may be tracked and/or locked to secure the terminal.
