  "textContent": "The present technique relates to a power supply device and method as well as a program which allow only a specific person to perform charging. A control unit controls a reader/writer to generate a vehicle ID read signal that is formed of a high frequency signal and used to read a vehicle ID recorded in an ID circuit, and supply the signal to a high-pass filter. The read signal or a write signal formed of the high frequency signal is superimposed on a power supply line and supplied to the high-pass filter. The high-pass filter supplies the vehicle ID read signal formed of the high frequency signal to the ID circuit. On the basis of the read signal, the ID circuit reads the vehicle ID stored in an IC built in the own circuit and transmits it as a response signal to a charger along a reverse path. An authentication part of the control unit turns on a selector switch when the vehicle ID being the response signal is determined to be legitimate, whereby a battery of an electric vehicle is charged with electric power superimposed on a low-pass filter. The present technique can be applied to a power supply system.",
