Protecting from Lunchtime Attack Using an Uncalibrated Eye Tracker Signal

Published: 02 June 2020 Publication History

Abstract

Eye movement-based biometric has been developed for over 15 years, but for now - to the authors’ knowledge - no commercial applications utilize this modality. There are many reasons for this, starting from still low accuracy and ending with the problematic setup. One of the essential elements of this setup is the calibration, as nearly every eye tracker needs to be calibrated before its first usage. This procedure makes any authentication based on eye movement a cumbersome and lengthy process.
The main idea of the research presented in this paper is to perform authentication based on a signal from a cheap remote eye tracker but - contrary to the previous studies - without any calibration of the device. The uncalibrated signal obtained from the eye tracker is used directly, which significantly simplifies the enrollment process.
The experiment presented in the paper aims at protection from a so-called ”lunchtime attack” when an unauthorized person starts using a computer, taking advantage of the absence of the legitimate user. We show that such an impostor may be detected with an analysis of the signal obtained from the eye tracker when the user clicks with a mouse objects on a screen. The method utilizes the assumptions that: (1) users usually look at the point they click, and (2) an uncalibrated eye tracker signal is different for different users.
It has been shown that after the analysis of nine subsequent clicks, the method is able to achieve the Equal Error Rate lower than 15% and may be treated as a valuable and difficult to counterfeit supplement to classic face recognition and password-based computer protection methods.
