Unauthorized tracking device detection and prevention

A non-transitory computer-readable storage medium storing executable instructions that, when executed by a hardware processor of a mobile device, cause the mobile device to perform steps comprising:

• detecting, by the mobile device, a plurality of advertisement signals from an unknown wireless device that changes an identity included within the advertisement signals after a passage of a predetermined interval of time, the plurality of advertisement signals received as the mobile device moves a distance greater than a broadcast range of the unknown wireless device during the predetermined interval of time, at least a first advertisement signal including a first identity of the unknown wireless device received before the mobile device moves the distance and at least a second advertisement signal including the first identity of the unknown wireless device received after the mobile device moves the distance;
• and
• in response to determining by the mobile device that the first advertisement signal received before the mobile device moves the distance greater than the broadcast range of the unknown wireless device and that the second advertisement signal received after the mobile device moves the distance greater than the broadcast range of the unknown wireless device both include the first identity, generating, by the mobile device, an interface to indicate a presence of the unknown wireless device to a user of the mobile device and to include a tracking history of the unknown wireless device, the tracking history based on the advertisement signals from the unknown wireless device.
