Abstract
Passive tracking of an electronic device (and, more generally, the anonymous use of location-based services) is avoided by identifying the electronic device with different addresses in a block of addresses when transmitting probe requests. In particular, the electronic device may request and then receive the block of addresses from an address-management server. Subsequently, when a probe request is transmitted (e.g., to an access point), the electronic device may use one of the addresses in the block of addresses instead of the media access control (MAC) address. Furthermore, whenever subsequent probe requests are transmitted, the electronic device may include a different address in the block of addresses.
