This paper describes the project in which Internet and wireless GIS based e-Crime system is used for crime monitoring, crime investigation, crime reporting, real time crime update and searching for criminals. In this project a model of location based services for crime control was developed. It was developed for real time crime access to help the Thai police to be more effective and efficient in crime control
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, and 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 for the citizens. 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 frontline officers, and assist in local problem-solving initiatives to reduce crime and reassure 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 in 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.
LBS Model for Crime Control
Figure 1 shows the LBS model for crime control. The users, both police and citizens, may be connected to the system by PDA or any PC connected with internet. The system will check for the authentication and authorization [4] to identify the source of a message. Based on the security policy of the system, the authentication process can deny or allow the user to access the system. The authorization process is used to control access to resources once identity has been verified. Then the data will be obtained by GPS and data mining and converted to longitude and latitude and sent to the database. The database consists of crime data and GIS data which will be integrated before sending to the server. The HTTP server/Map Server/WAP server will do the computation. The Web browser/WAP browser is used for viewing the results.
