1. A device tracking detection method, applied to a first electronic device, wherein the first electronic device comprises a target module, and the target module is configured to cache location information of a location at which the first electronic device is located, and the method comprises:
obtaining, by the first electronic device, location information from the target module and recording the obtained location information as location information of the first electronic device, wherein a set of the location information of the first electronic device is first trajectory information;
obtaining, by the first electronic device, location information from the target module when a first Bluetooth signal is received based on a first signal filter;
recording, by the first electronic device, the location information obtained at a time when the first Bluetooth signal is received, as location information of a first Bluetooth peripheral, wherein a set of the location information of the first Bluetooth peripheral is second trajectory information;
determining, by the first electronic device, whether it is in a target state, wherein the target state is a state in which a moving speed is greater than a preset speed threshold;
obtaining, by the first electronic device when in the target state, location information within a second duration from the first trajectory information, wherein the second duration is terminated at a time when the first electronic device receives the first Bluetooth signal, and the second duration is a period duration during which the first Bluetooth peripheral broadcasts the first Bluetooth signal;
inserting, by the first electronic device, the location information obtained within the second duration into the second trajectory information to update the second trajectory information; and
alerting, by the first electronic device when similarity between the first trajectory information and the updated second trajectory information is greater than a preset similarity threshold, a user of being tracked by the first Bluetooth peripheral.
