Secure and efficient mobile personal health data sharing in resource constrained environments.

Although personal health record (PHR) systems are widely used in the developed world, little has been done to explore the utility of these PHR systems in the developing world. One of the key reasons behind this is the fact that a lot of areas in the developing world suffer from technological impediments that are a result of poor infrastructure, low literacy, intermittent power connectivity, and unstable bandwidth connectivity. In technological resource constrained environments such as these, deploying standard PHR systems is challenging and so it makes sense to redesign these systems to cope with the environmental limitations in order to offer users a usable and reliable platform.
