THE REQUIREMENTS OF A CRIMINAL JUSTICE SYSTEM ARE REVIEWED, THE ISSUES OF PRIVACY AND SECURITY ARE ADDRESSED, AND BASIC COMPUTER HARDWARE AND SOFTWARE NEEDS ARE DESCRIBED. THE PROPOSED MULTILEVEL SYSTEM WOULD CONSIST OF FILES OF LOCAL OR REGIONAL INTEREST (ASSOCIATED MOSTLY WITH LOCAL AND STATE POLICE), FILES UTILIZED IN THE OPERATIONS OF INDIVIDUAL STATE-LEVEL JUSTICE AGENCIES (COURT, PROBATION, CORRECTIONS, AND PAROLE), AND FILES ON STATEWIDE STOLEN PROPERTY, MOTOR VEHICLES, AND CRIMINAL HISTORIES. CHARTS, TABLES, STATISTICS, COST DATA, AND OTHER SUPPORTING MATERIALS ARE INCLUDED AS PART OF THE DETAILED DESCRIPTION OF THIS PROPOSED SYSTEM. ALTERNATIVE APPROACHES TO THE SYSTEM'S DESIGN ARE REVIEWED AND COST ESTIMATES ARE GIVEN. THE MANAGEMENT PROBLEMS ASSOCIATED WITH IMPLEMENTATION ARE DISCUSSED. A FINAL SECTION SETS UP A PLAN FOR IMPLEMENTATION, DESCRIBES A STEP-BY-STEP METHOD FOR PHASING IN THE SYSTEM, AND RECOMMENDS BID PROCEDURES FOR THE PURCHASE OF THE NECESSARY HARDWARE AND SOFTWARE. THE TEXT OF A PROPOSED CONNECTICUT LAW IN DATA SECURITY AND PRIVACY IS APPENDED.
