In the UK, where the recent Queen’s speech about national identity cards generated lots of — mostly negative — coverage, another potentially invasive technology is being tested with very few criticism. For example, several police departments are now testing a 3D biometric facial recognition software from Aurora, a company based near Northampton.

The use of facial recognition “is rapidly becoming the third forensic science alongside fingerprints and DNA,” according to a police officer who talked to BBC News for “How your face could open doors.” The company claims its software is so sophisticated it can make the distinction between identical twins. And if the civil liberties groups continue to be neutral, this technology could also be deployed in airports or by private companies.

Even banks are thinking to put cameras in their ATM machines to identify you. The good thing is that you will not have to remember your PIN. On the other hand, as with every new technology, is it safe for your privacy and is it possible to hack the system? Read more before making your decision.
