Abstract:
1. A method for checking visitors comprising: detecting a subject attempting to enter a facility; acquiring a biometric signal from the subject; extracting a biometric of the subject from the biometric signal; and performing a quality measure on the biometric to determine whether the quality of the biometric is sufficient for matching to another like biometric; and wherein: if the quality measure of the biometric is acceptable, then a biometric, which matches the biometric of the subject, is looked for in a biometric database to determine whether the subject can be admitted to the facility; if a biometric is found in the database, which matches the biometric of the subject, then the subject is denied entry to the facility; and if the biometric, which matches the biometric of the subject, is not found in the database, then the biometric of the subject is enrolled in the database.
