MISCELLANEOUS RESULTS FROM FIELD TESTS OF AUTOMATED PERSONNEL IDENTIFICATION SYSTEMS UNDER CONSIDERATION BY THE U.S. AIR FORCE ARE REPORTED.
Abstract
THE PURPOSE OF THE TESTS WAS TO DETERMINE WHETHER AUTOMATED SPEECH, HANDWRITING, AND FINGERPRINT VERIFICATION EQUIPMENT COULD BE USED TO CONTROL ACCESS TO RESTRICTED AREAS ON MILITARY BASES AND INSTALLATIONS. TEST RESULTS ARE REPORTED IN DETAIL AND SUMMARIZED IN OTHER VOLUMES (SEE NCJ-57683-57685). THIS VOLUME REPORTS MISCELLANEOUS FINDINGS PERTAINING TO THE FOLLOWING: (1) USE OF A DETENTION MODULE (A SMALL ROOM OR BOOTH) IN CONNECTION WITH THE VERIFICATION PROCEDURE; (2) STATISTICAL INDEPENDENCE OF ERROR RATES (FALSE VERIFICATION AND FALSE REJECTION) FOR THE THREE SYSTEMS; (3) EFFECTS OF VARIOUS PROCEDURES FOR BRIEFING SYSTEM USERS; (4) HUMAN FACTORS ENGINEERING (USER AND OPERATOR COMMENTS AND RECOMMENDATIONS); (5) CALIBRATION AND FIELD ADJUSTMENT OF THE INSTRUMENTS; (6) OPERATOR TRAINING; AND (7) EFFECTS OF THE OPERATIONAL ENVIRONMENT (WEATHER AND NOISE) ON ERROR RATES. AMONG THE FINDINGS REPORTED ARE THAT BRIEFINGS, INCLUDING AN AUDIOVISUAL PRESENTATION AND A DEMONSTRATION OF THE EQUIPMENT, SHOULD BE GIVEN TO FIRST-TIME USERS OF VERIFICATION SYSTEMS. IT WAS ALSO FOUND THAT USERS LIKED LEAST THE SPEECH VERIFICATION SYSTEM (THE QUICKEST AND MOST ACCURATE OF THE THREE SYSTEMS TESTED) AND UNIFORMLY DISLIKED THE DETENTION MODULE. (LKM)
