MAC Address Randomization Increases Device Anonymity … In addition, during the connection to the AP, customers were not notified upfront that their movements would be tracked, and historic location data could be used for marketing purposes or sold to third parties. Several companies were reportedly logging and tracking the addresses of nearby devices in unassociated states. The MAC address is a Layer 2 (L2) address used to identify the source (sender) and the destination (receiver) of frames by most 802 network technologies, including Ethernet, Bluetooth and Wi-Fi.īack in 2013, the privacy implications of targeted probe requests started to become widely publicized. Unique MAC Addresses Enable User Privacy Infringement in Wireless NetworksĮvery Wi-Fi radio has a unique 48-bit identifier called a MAC address that is assigned by the manufacturer. As a countermeasure to this privacy threat, OS developers are anonymizing MAC addresses, thereby raising technical concerns among network operators. Wi-Fi access points, however, can monitor device locations without user consent by means of MAC addresses. Although a growing number of applications make use of location data, operating systems (OSs) provide the ability to turn off location services provided by the GPS or cellular/Wi-Fi connectivity. Privacy on tracking networks can be controlled using the temporary address so that participation with the tracking network is also temporary.In the era of mobility, location tracking is a major privacy concern for portable device users. Networks that use MAC-based access inherently track devices. Users can see which MACs are generated for each network in the Wi-Fi scan list, even before joining the network Since addresses are generated randomly, it is very unlikely that two devices on the same network will generate the same address.Ī new MAC will be used whenever a new address has been generated and the device re-joins the network Users are always in control - users can control enablement of the feature at any time for each network.Īddresses are generated randomly for every networkĪddresses are not linked to your identityĪddresses are updated for all networks daily by the device, NO server is involved in address generation. The introduction to the feature is mentioned in the "Build trust through better privacy" video ( ).
