Abstract:
A method of detecting pre-recorded biometric information comprising the steps of:receiving biometric information provided to a biometric information input device from a biometric information source;providing first digital data derived from the received biometric information;comparing the first digital data to stored digital data stored in memory means, the stored digital data derived from previously provided biometric information; and,when (i) the first digital data and the stored digital data are similar such that a likelihood that the first digital data and the stored digital data are provided in dependence upon two instances of same biometric information is above a predetermined registration likelihood and (ii) such that a likelihood that the first digital data and the stored digital data are provided in dependence upon two different instances of received biometric information provided from the biometric information source at a different time one from the other is below a predetermined likelihood, providing an indication of pre-recorded biometric information.
