A dynamic context aware role based access control model for wireless network's application case study in mobile GIS

摘要

The security model proposed for the Geographic Information Systems (GIS) is a data, which is capable of visualizing technology and has the capability to apprehend, cache, verify, amalgamate, engineer and exhibit data with the help of digitized maps. It has enormous applications in the field of engineering, business management process, communication both in the private and public regions. A GIS can help increase an organization's productivity and the quality of its decisions. Mobile GIS is a new research area in GIS. Over the last 10 years or above, there has been an information explosion that leads to have a lot of examples in GIS application which has resulted in many spatial data commodities for the distinct organizational functionalities. The applications clearly are favorable to the organizations which are confronting with the threat of implementing applications in Mobile GIS technology. The proposal is based on the working of the dynamic context aware role based access control model[6]. However, the GIS world is encountered with three dominant issues, which are (1). The progress beyond GIS deployment method in the system to make way for the next generation outstanding process, (2). New beliefs for remodeling the deployment of GIS applications to be able to adhere to dynamic requirements [1] and (3). To fathom and accomplish the Mobile GIS prospects owed to the startling evolution in wireless communication (WiMAX or Wi-Fi) technology. In our work, we present an overall analysis on wireless communication systems and the concept of Mobile GIS. The main research problems in Mobile GIS and the architecture is also a core problem. This kind of Mobile GIS architecture can solve the problem of client side mobile devices and improve efficiency of the Mobile GIS. With the above issues at backdrop, there is an inherent need to establish a standardized abstract ground work for perspective of Mobile GIS application and deploying it among organizations. For this purpose to over come the issues involved in forgery, replay and traceability there is a deployment of the dynamic context aware security model as depicted in the proposed model. This paper addresses the fact that this model can be applied for real time applications.
