Abstract
An apparatus, method and computer program wherein the apparatus comprises:a plurality of quantum dot-graphene field effect transistors; circuitry configured to provide an individual drain-source bias voltage to each of a plurality of quantum dot-graphene field effect transistors, wherein different individual drain-source bias voltages have different parameters, to enable the plurality of quantum dot-graphene field effect transistors to detect light from a user of an apparatus; and circuitry configured to obtain output signals from each of a plurality of quantum dot-graphene field effect transistors where the output signal is dependent upon both the light detected by the quantum dot-graphene field effect transistor and the parameters of the drain-source bias voltage to enable the obtained output signals to be used as a scrambled identification signal of the user of the apparatus.
