Rethinking privacy with a mobile device

By Emilio Castellanos

We are entering times where mobile geolocation will change our concept of privacy. Whether we embrace it or become afraid of it and how it is regulated greatly depends on how we choose to use it or abuse it.

Privacy has become more elusive since the internet era. Personal information posted online on social sites along with information collected through webcam services, street cameras, records stored by financial companies, etc., is all susceptible to be intercepted by 3rd parties.

However privacy issues become even more critical when we consider the mobile device: it contains a chip which constantly broadcasts your whereabouts. This locator has been monitored by government agencies since 2005 (FCC's E911) and is now standard on all new mobile phone models. Some devices will emit a signal even while turned off.
