A method includes receiving, by a first Bluetooth device, an identity resolving key (IRK) from a server, and generating a resolvable private address based on the IRK. The method further includes sending, by the first Bluetooth device, a broadcast message. The broadcast message includes the resolvable private address. The resolvable private address is successfully verified by a second Bluetooth device pre-configured with the IRK.
