Abstract

This application provides a device tracking detection method and an electronic device, and is related to the field of terminal technologies. The device tracking detection method is applied to a first electronic device. The method includes: determining that the first electronic device is tracked by a Bluetooth peripheral when a moving state successively changes for a plurality of times and there are scanning records of a first type within a preset duration. It can be understood that the first electronic device is accompanied by the Bluetooth peripheral in a plurality of successive different moving states, that is, the Bluetooth peripheral changes with change of the moving state of a user.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a first electronic device, a first Bluetooth signal through a first signal filter when it is detected that a moving state has changed, wherein the first signal filter is configured to receive the first Bluetooth signal, and wherein the receiving, by the first electronic device, the first Bluetooth signal through the first signal filter when it is detected that the moving state has changed comprises:
enabling, by the first electronic device, a timer upon detecting that the moving state has changed;
receiving, by the first electronic device, the first Bluetooth signal through the first signal filter; and
stopping receiving, by the first electronic device, the first Bluetooth signal upon expiration of the timer, wherein a timing duration of the timer is greater than a period during which a Bluetooth peripheral broadcasts the first Bluetooth signal;

storing, by the first electronic device, scanning records of a second type when the first electronic device detects the first Bluetooth signal, wherein there is a correspondence between the scanning records of the second type and a physical address carried in the first Bluetooth signal; and
outputting, by the first electronic device, alert information for alerting a user of being tracked by the Bluetooth peripheral when a quantity of the scanning records of the second type corresponding to the physical address is greater than a first threshold.

2. The method according to claim 1 , further comprising:
before the receiving, by the first electronic device, the first Bluetooth signal through the first signal filter, enabling, by the first electronic device, a preset mode, wherein in the preset mode, the first electronic device is capable of receiving the first Bluetooth signal based on the first signal filter.

3. The method according to claim 2 , wherein the enabling, by the first electronic device, the preset mode comprises:
displaying, by the first electronic device, a first screen, wherein the first screen comprises a first control; and
enabling, by the first electronic device, the preset mode in response to a trigger operation by the user on the first control.

4. The method according to claim 3 , wherein the first screen is a system desktop, and the displaying, by the first electronic device, the first screen comprises:
displaying, by the first electronic device, the system desktop in response to the trigger operation by the user, wherein the system desktop comprises a first prompt box, and the first prompt box comprises the first control; and
enabling, by the first electronic device, the preset mode in response to an enabling operation by the user on the first control.

5. The method according to claim 1 , wherein the storing, by the first electronic device, the scanning records of the second type comprises:
inserting, by the first electronic device, the scanning records of the second type into a preset second data table, wherein in the preset second data table, there is the correspondence between the scanning records of the second type and the physical address carried in the first Bluetooth signal.

6. The method according to claim 5 , wherein the outputting, by the first electronic device, the alert information for alerting the user of being tracked by the Bluetooth peripheral when the quantity of the scanning records of the second type corresponding to the physical address is greater than the first threshold comprises:
identifying whether a distance indicated in a set of location information in the preset second data table is greater than a preset distance threshold;
when the distance is greater than the preset distance threshold, identifying whether a duration indicated in a set of times comprised in the preset second data table is greater than a preset duration threshold;
when the duration is greater than the preset duration threshold, identifying whether the quantity of the scanning records of the second type in the preset second data table is greater than the first threshold; and
when the quantity is greater than the first threshold, outputting, by the first electronic device, the alert information for alerting the user of being tracked by the Bluetooth peripheral.

7. The method according to claim 1 , wherein the outputting, by the first electronic device, the alert information for alerting the user of being tracked by the Bluetooth peripheral comprises:
popping up, by the first electronic device, a first notification in a navigation bar of a second screen that is being displayed; and
displaying, by the first electronic device, the alert information in response to a pull-down operation by the user on the navigation bar.

8. The method according to claim 7 , wherein the alert information further comprises a second control, and the method further comprises:
after the displaying the alert information:
establishing, by the first electronic device, a Bluetooth connection with the Bluetooth peripheral based on the physical address carried in the first Bluetooth signal in response to a trigger operation by the user on the second control; and
controlling, by the first electronic device, the Bluetooth peripheral to perform a function of alerting.

9. The method according to claim 1 , wherein the outputting, by the first electronic device, the alert information for alerting the user of being tracked by the Bluetooth peripheral comprises:
controlling, by the first electronic device, a motor of the first electronic device to vibrate; or
controlling, by the first electronic device, a speaker of the first electronic device to output an alert tone; or
controlling, by the first electronic device, a light indicator of the first electronic device to blink; or
when the alert information is a control command, sending, by the first electronic device, the control command to a wearable device with which a communication connection has been established, to control the wearable device to vibrate or output the alert tone.

10. An electronic device, comprising a memory, at least one central processing unit, and a computer program stored in the memory and capable of running on the at least one central processing unit, wherein when the computer program is executed by the at least one central processing unit, the electronic device is caused to perform:
receiving a first Bluetooth signal through a first signal filter when it is detected that a moving state has changed, wherein the first signal filter is configured to receive the first Bluetooth signal;
storing scanning records of a second type when the electronic device detects the first Bluetooth signal, wherein there is a correspondence between the scanning records of the second type and a physical address carried in the first Bluetooth signal, and wherein the storing the scanning records of the second type comprises:
inserting the scanning records of the second type into a preset second data table, wherein in the preset second data table, there is the correspondence between the scanning records of the second type and the physical address carried in the first Bluetooth signal; and

outputting alert information for alerting a user of being tracked by a Bluetooth peripheral when a quantity of the scanning records of the second type corresponding to the physical address is greater than a first threshold, wherein the outputting the alert information for alerting the user of being tracked by the Bluetooth peripheral when the quantity of the scanning records of the second type corresponding to the physical address is greater than the first threshold comprises:
identifying whether a distance indicated in a set of location information in the preset second data table
