Design and Implementation of Anti - Lost U Disk System Based on Bluetooth 4.0 Technology

In order to solve the problem of inconvenience and economic loss caused by the loss of U disk, this paper proposes an anti-lost U disk system based on Bluetooth 4.0 to solve it. The system integrated big data analysis, Bluetooth communication, Global Positioning System, embedded technology, to achieve the U disk from the safe distance, the system alerts the user, U disk loss, the system records the loss of location and lost time. In addition, data analysis can be carried out by recording the user's missing information. This system has the advantages of low power consumption, small volume, low price, etc., and its data analysis results can provide reference for network security, community service and so on.
