1. A method for identifying an individual, comprising: receiving, with a processor, a request for identification of an individual, the request for identification including first input biometric identification information for the individual from one or more biometric identification information imagers; converting, with the processor, the first input biometric identification information for the individual to an individual identification text string; establishing a threshold criteria for comparing the individual identification text string to a plurality of previously-stored text strings representing biometric identification information for a population of identifiable individuals; comparing, with the processor, the individual identification text string to the plurality of previously-stored text strings representing the biometric identification information for members of the population of identifiable individuals; and outputting results of the comparing to identify whether the individual is a member of the population of identifiable individuals, the output results (1) including only those results of the comparing that meet the established threshold criteria, and (2) being presented as a rank-ordered list derived from the population of identifiable individuals based on text strings from the plurality of stored text strings being determined to be substantially equivalent to the individual identification text string according to the established threshold criteria.
2. The method of claim 1 , further comprising: receiving, with the processor, a request from the individual to be enrolled as a member of the population of identifiable individuals; receiving, with the processor, basic textual identification information identifying the individual; collecting, with the processor, available biometric identification information for the individual from one or more biometric identification information data sources; converting, with the processor, the collected biometric identification information for the individual to one or more text strings; and storing the one or more text strings in association with the basic textual identification information for the individual as one or more of the plurality of stored text strings representing the biometric identification information for the population of identifiable individuals.
