Minimising Information Asymmetry by Using Proxies

The fast growing number of social-network services utilising location information has also increased the interest in privacy for such systems. Many interesting ideas and proposals have appeared. One of the most interesting is perhaps the notion of minimising asymmetry of information flow. This idea can also be applied in the area of ambient assisted living. The work described here reports on some initiatives on location-aware systems and ambient assisted living. The combined experiences gained from these projects have led to the development of a model for minimising asymmetry by proxies in an ambient assisted living environment.
