Fingerprint sensors are supposed to make our smartphones a bit more secure, but some can be tricked by fake fingers made of clay.
Chinese firm Vkansee, which makes fingerprint sensors, demonstrated at Mobile World Congress how lower-res sensors can be fooled. The fake finger, according to the BBC report, doesn’t even have to be a good copy.
Vkansee’s sensors have a 2,000 dpi resolution, which means they are capable of picking up “micro features” of fingerprints, right down to the presence of sweat pores.
It’s unlikely that you’ll be caught out in the exact way demonstrated – people had to keep their finger in a gel for five minutes to produce the copy. But it’s food for thought, particularly if you believed that fingerprint sensors were infallible.
