<p dir="ltr">Bluetooth 4.2 LE Privacy 1.2</p>
<p dir="ltr"><a href="https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=286439">https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=286439</a></p>
<p dir="ltr">> 5.4.5 Privacy Feature Bluetooth LE supports a feature that reduces the ability to track a LE device over a period of time by changing the Bluetooth device address on a frequent basis. The privacy feature is not used in the GAP discovery mode and procedures but it is used, when supported, during connection mode and connection procedures. </p>
<p dir="ltr">> In order for a device using the privacy feature to reconnect to known devices, the device address, referred to as the private address, must be resolvable by the other device. The private address is generated using the device’s resolving identity key (IRK) exchanged during the bonding procedure. </p>
<p dir="ltr">> 6.5 DEVICE PRIVACY A private device shall not use its Identity Address in any packet type used on the advertising channels. </p>
<p dir="ltr">> 10.7 PRIVACY FEATURE The privacy feature provides a level of privacy which makes it more difficult for an attacker to track a device over a period of time. The requirements for a device to support the privacy feature are defined in Table 10.3. </p>
<p dir="ltr">And so on... </p>
