Remembering strong passwords is tough. That’s why a Japanese smartphone maker has launched a phone that uses iris scanning technology to unlock your phone.
It uses the front camera to look into your eyes and map the pattern of blood vessels. If the pattern matches the one you originally set up, you’re cleared to use the phone.
The great thing about using your eyes for security is that they’re even more complicated than fingerprints, making them impossible to fake.
This sort of biometric security, where your body is your password, has been in phones and tablets for years, but they’ve always been relatively easy to get around.
Back in 2011, Motorola launched the Atrix, the first phone with a fingerprint scanner. Unfortunately, like all smartphone fingerprint scanners, it could be fooled by a picture of your fingerprint printed on latex.
Later that year, Android launched face recognition, but it could be tricked by a photo.
While iris scanning is much more secure than fingerprints or facial recognition, it’s unlikely to be seen as perfect as you’ll always need to hold your phone up in front of your face to unlock it. So other types of biometrics will be developed.
Amazon, for example, wants to use your phone’s front camera to recognise your ear, although that sounds more awkward to use than an iris scanner.
A more practical way to secure your phone is with your heartbeat. Your heart creates a unique rhythm that can’t be faked. All you’d need to do is wear a smartwatch to monitor your heart.
With all this new security tech, biometrics is going to create a new world of super secure gadgets.
