Engadget, a foreign media, reported that Apple had submitted a patent application to the U.S. Patent and Trademark Office to prevent iOS devices from being stolen by using accelerometers and special controllers. This patent uses the accelerometer and controller provided by iPhone or iPad and other devices. Users can set the system sensitivity, alarm sound and volume through the application to detect the acceleration of the device in real time, and analyze whether the acceleration fed back by the accelerometer meets the preset "theft behavior" standard. Once the system determines that theft is detected, the device will automatically give an alarm, So as to achieve the purpose of anti-theft.

It is reported that Google has similar patents in Project Glass.
