Verification of Keyboard Acoustics Authentication on Laptops and Smartphones Using WebRTC

Abstract

This paper evaluates authentication based on sounds emitted while typing on a laptop’s keyboard only with the help of the integrated microphones and a smartphone placed nearby. The sound samples of 26 individuals were recorded in a novel real-world scenario using only web technologies. The data of laptop and the smartphone was compared based on existing approaches. They can reach Equal-Error-Rates (EERs) of 11.2% on the laptop data and 9.3% on the smartphone data.
