SWAMI is about one of the most pressuring topics for wearables as well as information technology: privacy.

"While AmI enthusiasts foresee a future information society where the emphasis is on greater user-friendliness, more efficient services, user empowerment and support for human interactions, we know well that the adoption rate of ambient intelligence environments will depend on how secure it can be made, how privacy and other rights of individuals can be protected and how individuals can come to trust the intelligent world that surrounds them and through which they move."
