Scientists have been able to reconstruct a person's fingerprint just from the sound of their finger sliding across a mobile phone's touch screen. In this way, researchers from the USA and China have raised the alarm about a vulnerability in the system of protecting mobile devices through biometric authentication with the fingerprint of their owner, reports BTA.

This is reported in an upcoming report of the research group, published on the portal of the computer security conference NDSS Symposium 2024 ("Security of networks and distributed systems"), which will be held from February 26 to March 1 in San Diego, California. 

According to the report, scientists have developed the new PrintListener technology to breach the biometric authentication system, which is a new threat to cyber security. It can recover fingerprints by analyzing the sound generated when a finger is swiped on a touch screen of a mobile device. This leads to an easy breach of the device's security through the fingerprint authentication app.

Using the new system, higher rates of successful fingerprint reproduction were recorded than when using the already existing MasterPrint technology, which works on the basis of data analysis by artificial intelligence.
