This invention discloses a biometric method eliciting a migrating biometric characteristic from individuals, the method including storing at least first and second templates of at least one migrating biometric characteristic for each of a population of individuals, the first template being a reference sample of an individual's biometric characteristic and the second template being initially derived from the first template, and comparing an individual's first and second templates to a fresh sample provided by the individual and, if the fresh sample is found to sufficiently resemble the first and second templates, modifying the second template to take into account differences between the reference sample and the fresh sample. A biometric system eliciting a migrating biometric characteristic from individuals is also disclosed. |

DETAILED DESCRIPTION The present invention seeks to provide an improved biometric system and methods useful in implementing such a system.
There is thus provided in accordance with a preferred embodiment of the present invention a secured biometric system including a portable secured biometric information receptacle storing biometric information regarding an individual and a terminal which does not store the biometric information and which is operative to compare the biometric information on the biometric information receptacle to biometric information obtained directly from the human bearer of the biometric information receptacle.
Also provided, in accordance with another preferred embodiment of the present invention, is a biometric system eliciting a migrating biometric characteristic from individuals, the system including a biometric information repository storing at least first and second templates of at least one migrating biometric characteristic for each of a population of individuals, the first template being a reference sample of an individual's biometric characteristic and the second template being initially derived from the first template, a repository keeper operative to compare an individual's first and second templates to a fresh sample provided by the individual and, if the fresh sample is found to sufficiently resemble the first and second templates, to modify the second template to take into account differences between the reference sample and the fresh sample.
Also provided, in accordance with another preferred embodiment of the present invention, is a secured biometric device eliciting a biometric characteristic from individuals, the system including a biometric information repository storing a biometric information file for each of a population of individuals, each biometric information file of a particular individual including a representation of a sample of at least one biometric characteristic, and enrollment operator identification information identifying the enrollment operator who presided over elicitation of the sample from the individual
