METHOD FOR PROTECTING PRIVACY WHEN USING A BLUETOOTH DEVICE

The user's Bluetooth device substitutes a pseudonym address for the Bluetooth Device Address (BD_ADDR). The pseudonym address is a randomized version of the BD_ADDR. The pseudonym address is used in all the functions of the Bluetooth device that normally use the BD_ADDR, including the frequency...

description The user's Bluetooth device substitutes a pseudonym address for the Bluetooth Device Address (BD_ADDR). The pseudonym address is a randomized version of the BD_ADDR. The pseudonym address is used in all the functions of the Bluetooth device that normally use the BD_ADDR, including the frequency hopping sequence, the device access code, the initialization key in link encryption, the authentication code, and the various packet addresses. In this manner, the user's privacy is protected by preventing the user's identity, routes, and activities from being correlated with his/her device's address. In addition to the Bluetooth standard, the technique also applies to other wireless standards.
