Universal Adversarial Spoofing Attacks against Face Recognition

no code implementations2 Oct 2021 Takuma Amada, Seng Pei Liew, Kazuya Kakizaki, Toshinori Araki

We assess the vulnerabilities of deep face recognition systems for images that falsify/spoof multiple identities simultaneously.

Adversarial Image Translation: Unrestricted Adversarial Examples in Face Recognition Systems

no code implementations9 May 2019 Kazuya Kakizaki, Kosuke Yoshida

Thanks to recent advances in deep neural networks (DNNs), face recognition systems have become highly accurate in classifying a large number of face images.

Lightweight Lipschitz Margin Training for Certified Defense against Adversarial Examples

no code implementations20 Nov 2018 Hajime Ono, Tsubasa Takahashi, Kazuya Kakizaki

Lipschitz margin training (LMT) is a scalable certified defense, but it can also only achieve small robustness due to over-regularization.

Differentially Private Chi-squared Test by Unit Circle Mechanism

no code implementations ICML 2017 Kazuya Kakizaki, Kazuto Fukuchi, Jun Sakuma

This paper develops differentially private mechanisms for $\chi^2$ test of independence.

Differentially Private Analysis of Outliers

no code implementations24 Jul 2015 Rina Okada, Kazuto Fukuchi, Kazuya Kakizaki, Jun Sakuma

One is the query to count outliers, which reports the number of outliers that appear in a given subspace.
