Personal privacy is something that once lost, may be difficult to pull back. If we have innocently signed away our data privacy rights because of trust in the status quo, there are no guarantees that our personal data will not be used against ourselves or our family members. The smart city train has already left the station. In a world where the population is increasing and resources are finite, we need to find smarter ways of living together. Smart technologies hold the key to making this happen but we need to proceed with caution and build a layer of respectful trust and privacy in our smart places.
