1. A method of forming a biometric repository to prevent imposter activity, comprising:
- forming in a database of a computer system an enrollment structure, said enrollment structure having a hierarchy of quality levels, each quality level having data identifying one or more aspects or features of a person, where the features of a person is more comprehensive and detailed as the level increases in the hierarchy, whereby the assurances that a person is who he/she says they are increases;
forming in the database, a hierarchy of trust levels, each trust level storing one or more sets of biometric data of a person, whereby, as the trust level increases in the hierarchy, the assurances that the person is who he/she says they are increases;
using the quality level in the enrollment structure and the trust level of the biometric data in the database to provide a score relating to said assurances; and
defining the score to be no larger than either the quality level in the enrollment structure or the trust level of the biometric data in the database.

Abstract
A system employing enrollment information and the quality of the enrollment information. The enrollment information includes data unique to the identification of a person. The system also stores biometric sensor quality information. When a person seeks to authenticate his/her identity, the sensor transmits the sensor quality data along with the biometric attribute data to the system. The transmitted data is correlated with the enrollment data, and quality of the enrollment data, to produce a score indicative of the probability of a correct identification.
