Claim 14:
15. A computer program product loadable stored in a non-transitory memory of at least one processing circuit and comprising software code portions that, when the product is run on the at least one processing circuit, execute the following steps:
collecting at least one electrophysiological signal of a human over a limited time duration;
discontinuing the collecting at an expiry of the limited time duration;
computing a set of electrophysiological signal features as a function of the at least one collected electrophysiological signal, the computing comprising at least one of:
i) providing at least one reference electrophysiological signal and applying dynamic time warping processing to the at least one collected electrophysiological signal and to the at least one reference electrophysiological signal;
ii) applying stacked-auto-encoder artificial neural network (SAE ANN) processing to the at least one collected electrophysiological signal; or
iii) filtering the at least one collected electrophysiological signal via joint low-pass and high-pass filtering using a set of filtering parameters including low-pass filter parameters and high-pass filter parameters having a set of low-pass cut-off frequencies and a set of high-pass cut-off frequencies, respectively;

applying pattern recognition processing to the computed set of electrophysiological signal features, the pattern recognition processing producing a virtual key signal indicative of an identity of the human; and
applying the virtual key signal to a user circuit to switch the user circuit between a first state and a second state as a result of the virtual key signal matching an authorized key signal stored in the user circuit.
