People mistrust fingerprint devices, mostly because they associate fingerprinting with criminal activity. The average citizen thinks that the fingerprint registration could be stolen and used to implicate them in a crime. It can’t, of course, but that doesn’t change their perception. The same problem faces facial scanning/recognition software which has been used (unsuccessfully) to identify wanted criminals at sporting events. Retina scanners simply scare people – they don’t want anything being shined into their eye. So what can we do?
The smart folks at Fujitsu have come up with a new system to read a biometric. It’s non-intrusive, isn’t likely to be featured at a crime scene on a TV series but does provide a unique signature with little effort on the user’s part.
