The paper estimates the vulnerability of two commercial FR systems (Verilook and FaceVACS) to presentation attacks based on 3d custom silicone face-masks. The study is based on a new dataset, CSMAD-Mobile, introduced in the paper. Baseline performance values of several standard face-PAD methods ((LBP,LPQ,BSIF,IDA,color-textures)+SVM), computed using the new dataset, are also presented in the paper.
