Comments on “PassBio: Privacy-Preserving User-Centric Biometric Authentication”
Hee-Yong Kwon, Mun‐Kyu Lee · IEEE Transactions on Information Forensics and Security · 2022
In 2018, Zhou et al. proposed PassBio, a privacy-preserving biometric authentication scheme, in IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY (TIFS) (DOI: 10.1109/TIFS.2018.2838540). PassBio delivers its promise and effectively protects users’ privacy from malicious servers. However, we demonstrate that PassBio may be vulnerable in a more inclusive attack model with malicious clients.
