Abstract:
A method for anti-tracking of Bluetooth, comprising: a target Bluetooth device generating a first dynamic address every first pre-set time and broadcasting same; after connecting to a mobile device and obtaining a second dynamic address thereof, waiting to receive data sent by the mobile device; if the data is a pairing request, pairing with the mobile device, saving a second identity parsing key contained in the pairing request, returning a pairing response containing a first identity parsing key thereof to the mobile device, and continuing to wait to receive data; and if the data is a link encryption request, successively using identity parsing keys stored thereby of the mobile device to verify the second dynamic address, determining whether a second identity parsing key having been successfully verified exists, and if so, returning a success response to the connected mobile device and communicating with same, and ending the process, otherwise, returning an error code and disconnecting from same, and ending the process. In the present invention, a Bluetooth device periodically changes a dynamic address thereof, thereby effectively preventing data being stolen by a hacker.
