While 3D body scanners are being implemented in several European airports, the debate about our privacy is flaring up. Most opponents state that the pictures taken are an invasion of the privacy and the physical integrity of our bodies, because the full naked body is made visible. In the case where body scanning is used to prevent terrorists from boarding to the airplanes, one could utter that the safety of the passengers comes first, but in a commercial context this could bring companies in trouble. For our internet start-up, we will use the body scanners to let people virtually fit the clothing they will purchase online, but our prospects could be reluctant to engage with our service because of privacy issues. People could fear that their virtual (naked) twin will be visible to the entire world through internet. The pictures we (actually a self-scanning device) take are only visible for our client with a login and a password. Nobody else, including our company, ever sees the image. And frankly, a virtual twin of yourself isn’t really that sexy. Let alone recognizable.
