Introduction
Electronic government-to-citizen (G2C) refers to the use of information technologies by government agencies to provide citizens with more convenient access to government information and services, to improve the quality of the services [1]. The government needs to search for a better way to utilize Information Communication Technology (ICT) to improve government works and services to the citizens. Internet technology can improve government performance, be cost effective, increase accountability, improve resource management and provide better ways of communication between citizens and the public sector. This concept has been applied to several government agencies including police work-where it is referred to as e-Policing. e-Policing is the use of ICT in police work to improve effectiveness and efficiency, support front line officers, and assist in local problem solving initiatives to reduce crime and reassure the public [2]. The safety of citizens is the most important task of the government. Location Based Services (LBS) involve the ability to find the geographical location of a mobile device and provide services based on this location information [3]. LBS can offer tremendous benefits for the safety area, for example, tracking the location of a person who needs urgent help, or of a criminal who is wanted. In the case of emergency calls (e.g. robbery, hostage, murder, etc.) it is obvious that if the call responders have information concerning the location of the people making the call, then the response time can be reduced. This paper aims to design a model of location based services for crime control that reflects police and citizens demands. In addition, the security and privacy issues are also of concern. The prospects of crime control system The requirements for the modeling of location based services for crime control are derived from questionnaires from a survey of 100 Thai citizens and 100 Thai police between May to July 2003. According to the survey results, more than two-thirds of the respondents regard safety and security issues (emergency calls i.e. robbery, murder, theft, etc) as the primary reasons for wanting the system. They also want the system to provide information on crime for example crime warning messages, news reporting on crimes, report lost property and crime prevention information. In addition, contact information and digital maps showing the route to the nearest police station, other organizations that support victims, routes to get from one place to another and information regarding road works and accidents are also required. With requirements gathered from the survey, the modeling concept as described by the use case diagrams [4] were developed.
