THE SYSTEM CONFIGURATION, SEARCH PROCEDURE AND FORMAT, AND SECURITY ARE DESCRIBED FOR THE CHICAGO POLICE DEPARTMENT'S COMPUTERIZED IDENTIFICATION OF ARRESTEES SYSTEM.
Abstract
TO BEST MEET THE REQUIREMENTS OF ITS IDENTIFICATION SECTION, THE CHICAGO POLICE DEPARTMENT HAS A COMPUTER SYSTEM DESIGNED IN WHICH SEVEN TERMINAL SITES ARE HARDWIRED TO HAVE SIMUL-REAL-TIME ACCESS TO A FOUR-PHASE SYSTEM IV/90. THE PRIMARY SEARCH TECHNIQUE INVOLVES THE USE OF THE 'SOUNDEX' SYSTEM TO TRY FOR A 'HIT' IN THE FILE USING AN ARRESTED PERSON'S NAME. SEARCHES MAY ALSO BE MADE BY FINGERPRINT CODE (EITHER THE FULL CODE OR THE PRIMARY AND SECONDARY CLASSIFICATION), SEX, RACE, AND BIRTHDATE. WHEN A SEARCH RESULTS IN A 'HIT,' THE TERMINAL OPERATOR CAN REQUEST THE COMPUTER TO PROVIDE A MASTER-RECORD DISPLAY. FOR SECURITY PURPOSES, PHYSICAL ACCESS TO THE TERMINALS IS CONTROLLED, AND A BUILT-IN, FOUR-LEVEL SECURITY SYSTEM RESTRICTS DATA ACCESS TO AUTHORIZED PERSONNEL. A DETAILED AUDIT TRAIL IS PRODUCED WHENEVER THE FACILITY IS USED. HARD-COPY DAILY REPORTS ARE GENERATED TO INFORM SUPERVISORY PERSONNEL OF ANY RECORD MODIFICATIONS MADE THE PREVIOUS DAY. (RCB)
