We show that while these systems are capable of producing great accuracy, they produce templates of too little entropy. As a result, we present a reconstruction attack that takes a protected template, and reconstructs a facial image. The reconstructed facial images greatly resemble the original ones. In the simplest attack scenario, more than 78% of these reconstructed templates succeed in unlocking an account (when the system is configured to 0.1% FAR). Even in the "hardest" settings (in which we take a reconstructed image from one system and use it in a different system, with different feature extraction process) the reconstructed image offers 50 to 120 times higher success rates than the system's FAR.0 aOpen access — freely available to read.40uhttps://arxiv.org/pdf/2012.13293v1yRead the full paper (PDF) cERES c644d644 001040738CYBaMAINbMAINcSCICOMPd2026-09-01l0pYGE000905r2026-09-01 03:03:30uhttps://arxiv.org/pdf/2012.13293v1w2026-09-01yPAPER
