PDA Based Telemedicine System in a Web Based Environment

We live in an era of unimaginably rapidly advancing, amazing technologies that enable instantaneous flow of information - anytime, anywhere. The convergence of computers and networks has been the key force behind the development of these awe inspiring technologies. Increasing use of systems built using these information technologies (IT) is having a profound impact on our everyday lives. These technologies are becoming all pervasive and ubiquitous. Mobile communication is one of the prominent examples of the impact of IT on society. There is a flurry of activity in the development of novel applications that run on this infrastructure. Phones have gone from wireless - to small - to smart and currently to a situation where they can be used not only as devices to communicate with people but as entertainment devices (games, radios, mp3 players, cameras and now television); and, for serious personal applications such as location services, messaging and authentication-based services that includes banking. The fast paced development of these applications has been enabled by the flexibility of the underlying computing platform and the communication infrastructure. The key perquisite for the continued development and successful exploitation of IT is the notion of information assurance. Information Assurance has been defined as " information operations that protect and defend information and information systems by ensuring their availability, integrity, authentication, and nonrepudiation; including providing for restoration of information systems by incorporating protection, detection, and reaction capabilities".
