COMPUTERISED CRIME TRACKING INFORMATION SYSTEM

Department of Computer Science
ABSTRACT
This project work intends to automate the existing criminal records of the Nigeria police using Enugu criminal investigating department. The essence was to produce durable criminal records and avoidable lost of criminal records. Structural database management system (DBMS) was used in its development in other to eliminate redundancy in the compilation, its friendliness in responding to the user exhibits and also its reliability and efficiency in tracking down criminals. Another important feature of this system was that it provides user with the facilities for having the hard copies or print out of any relevant
5
document as well as the facilities to communication with the system. Tracking is the observing of persons or objects on the move and supplying a timely ordered sequence of respective location data to a model e.g. capable to serve for depicting the motion on a display capability. The traditional and age-old system of intelligence and criminal record maintenance has failed to live up to the requirements of the existing crime scenario. Manual processes neither provide accurate, reliable and comprehensive data round the clock nor does it help in trend prediction and decision support.

CHAPTER ONE
INTRODUCTION
11 Background of The Study
Man by nature is social, gregarious and cannot live in isolation To maintain peace and harmony in the society, man has to fashion out conduct and some laws to govern the conduct of members of the society When people appreciate these codes of conduct and laws, protection of lives and properties are guaranteed
Generally tracking is the observing of persons or objects on the move and supplying a timely ordered sequence of respective location data to a model eg capable to serve for depicting the motion on a display capability
The traditional and age-old system of intelligence and criminal record maintenance has failed to live up to the requirements of the existing crime scenario Manual processes neither provide accurate, reliable and comprehensive data round the clock nor does it help in trend prediction and decision support It also results in lower productivity and ineffective utilization of manpower The solution to this ever-increasing problem lies in the effective use of Information Technology Crime Tracking Information System uses computer-generated records as an interface for integrating and accessing massive amounts of location-based information
16
Crime tracking system allows police personnel to plan effectively for emergency response, determine mitigation priorities, analyses historical events, and predict future events Crime tracking system helps identify potential suspects to increase investigators suspect base when no leads are evident The ability to access and process information quickly while displaying it in a spatial and visual medium allows agencies to allocate resources quickly and more effectively In the ‗mission-critical‘ nature of law enforcement, information about the location of a crime, incident, suspect, or victim is often crucial to determine the manner and size of the response Crime tracking software helps co-ordinate vast amounts of location-based data from multiple sources It enables the user to layer the data and view the data most critical to the particular issue or mission
It is used world over by police departments, both large and small, to provide solutions for crime analysis, criminal tracking, traffic safety, community policing, Intranet/Internet mapping, and numerous other tasks
Crime tracking system helps crime officers determine potential crime sites by examining complex seemingly unrelated criteria and displaying them all in an interface It also helps them map inmate populations, fixtures, and equipment to provide for the safety of inmates by separating gang members, identifying high-risk or potentially violent inmates, and identifying hazardous locations in an area It reduces the potential for internal violence
17
by providing better command and control Traditionally, these activities have been supported by paper and pen Police officers now have the ability to immediately generate crime report directly relevant to the situation at hand Police agencies collect vast amounts of data from many sources including called-for-services, arrests, first information reports and daily report The same information provides a powerful decision making tool for investigators, supervisors, and administrators
