Leveraging Disentangled Representations to Improve Vision-Based Keystroke Inference Attacks Under Low Data

1 code implementation5 Apr 2022 John Lim, Jan-Michael Frahm, Fabian Monrose

We evaluate our method on real-life data using a variety of metrics to quantify the amount of information an attacker is able to recover.

Revisiting the Threat Space for Vision-based Keystroke Inference Attacks

1 code implementation12 Sep 2020 John Lim, True Price, Fabian Monrose, Jan-Michael Frahm

This indicates that these models are able to learn rich, meaningful representations from our synthetic data and that training on the synthetic data can help overcome the issue of having small, real-life datasets for vision-based key stroke inference attacks.

Tangent Images for Mitigating Spherical Distortion

1 code implementation CVPR 2020 Marc Eder, Mykhailo Shvets, John Lim, Jan-Michael Frahm

In this work, we propose "tangent images," a spherical image representation that facilitates transferable and scalable $360^\circ$ computer vision.
