ABSTRACT:
A firearm with an identification safety system for preventing use by an unauthorized user. The firearm includes a barrel for discharging the firearm therethrough, a butt section connected to the barrel, a trigger connected between the barrel and butt section for initiating discharge of the firearm and a safety switch operable between a first position preventing discharge of the firearm and a second position allowing discharge of the firearm. A pressure sensor is positioned in the butt section for sensing grasping of the butt section by a palm of a user and a scanning sensor is connected for scanning a palm print of the palm of the user and generating a data signal representative of the scanned palm print upon sensing grasping of the butt section by the pressure sensor. A memory unit stores data signals representative of palm prints of authorized users and a microprocessor is connected to both the scanning sensor and the memory unit for receiving the data signal from the scanning sensor and comparing the received data signal to the data signals stored in the memory unit. The microprocessor controls the safety switch to operate in the first position upon determining the received data signal does not match any of the data signals stored in the memory unit and controls the safety switch to operate in the second position upon determining the received data signal matches one of the data signals stored in the memory unit.
