Researchers have reportedly discovered a new side-channel attack that can extract a person’s fingerprints from the sounds made when a finger swipes across a touchscreen.

Toms Hardware reports that researchers from institutions in China and the United States have outlined an innovative attack targeting biometric security in a paper entitled “PrintListener: Uncovering the Vulnerability of Fingerprint Authentication via the Finger Friction Sound.” This attack utilizes the audio characteristics of a finger gliding across a touchscreen to infer attributes of the fingerprint pattern.

Thank you, very interesting, enjoyed the reading! Keep adding more of these, please.

I second this! It all started back in 2006, about the time they introduced the same fingerprint scanning "security" technique for notebooks.

The paper is here:

Of course everyone will start swiping with knuckles, scared by the possibility (actually extremely remote) that something like what is described in the paper actually works in the real world.

A much more dangerous attack, with almost 100% success :

Audio-Fingerprint is nothing new.

When I was still teaching we carried out a study in collaboration with other European universities.

The few websites that used this form of fingerprinting, naturally in combination with other techniques, have decreased this form of fingerprinting over time.

I still have the test website which is obviously no longer updated and therefore reports an error, but it works:

But this is AudioPhysicalFingersFingerprint, it is an entirely new field.

Certainly,this is evolution.
But everything new is rooted in the old.
And I bet it will have limited impact as you have already predicted as well.
Everyone who studies and/or deals with fingerprinting sooner or later comes to the same conclusion.
It attracts a lot,but it has limited impact.

Well, what is new is also usually old, or at least new things are not necessarily safer than old ones, unexpectedly face recognition just got a hit (in Thailand and Vietnam) JFYI:

This is just pure funny ... a six year old girl with knowledge of swiping her mother's fingerprint and then ordering stuff on Amazon. This girl has been very observant and a fast learner. Wonder what life will be like for the parents when she's ten years old.

Thanks to 'the Finder' for posting. This happened last year with a five year old girl ordering from Amazon.

Smart kids are smart, but when it comes to these technologies, all kids can do things you wouldn't expect.

The advice the guy that runs a small phone (sales and repairs) shop around the corner gave to my mom last time, after having explained her how to change settings of her (new) smartphone was:

"If you have issues, come here and we will try and solve them, if we are closed, ask the younger kids you can find, they will know how to ..."
