Abstract
A pressure key includes a pressure sensor, a microprocessor chip, a storage device, a port, a record button and an enter button. When the pressure key is connected to a computing device and the record button is pressed, the pressure sensor is triggered to record a pressure signal input by a user. The microprocessor chip converts the pressure signal into a password, stores the password into the storage device, and sends the password to the computing device to lock the computing device. When the pressure key is connected to the computing device again and the enter button is pressed, the microprocessor chip retrieves the password from the storage device and sends the password to the computing device. The computing device is unlocked if the received password matches the password stored in the computing device.
