METHOD OF LOCKING AN INPUT DEVICE

Abstract

An input device with a lock mechanism is provided. The input device has a storage unit, a pressure sensor, a microcontroller, and a locking unit. The storage unit is for storing information, typically private, sensitive files/documents. The pressure sensor is for generating pressure sensing signals if pressed. The microcontroller is for scanning the pressure sensing signals in real time, and generating and transmitting a lock signal to the locking unit. The locking unit is signaled to perform a lock operation on the storage unit in response to the lock signal, thereby preventing unauthorized access to the information of the storage unit. A related method is also provided.
