Distributed intelligent nodes as information filters in advanced telecare systems

The next generation of telecare systems will need to monitor and process vast amounts of personal data. These data might include both medical and lifestyle (or behavioural) information which may be highly sensitive. There is general unease with the concept of such data streaming out of the home on a regular basis without the knowledge of the client. The CarerNet model is being developed with a distributed intelligence approach which can be used to manage and control the flow of personal data. By establishing a hierarchical layering of information zones based on intelligent nodes within the home, and by agreeing with the client a set of circumstances which warrant external intervention, it is possible to filter the now of sensitive information between such zones. This reduces the intrusion while minimising the quantity of data and the errors transmitted throughout the system.
