Furthermore, huge amounts of information are being recorded
and stored daily about people’s behaviour, as they walk through
the streets, drive their cars and use the Web. While much of
this may be erased after a period of time, some is stored more
permanently, about which people may be naively unaware.
In 2020, it is likely that our digital footprints will be gigantic,
distributed everywhere, and in all manner of places and forms.
