Abstract

Systems and methods for detecting a presentation attack. Datasets of original images and attack samples are used to train a model that creates in a feature space of samples of original images a set of elements corresponding to each sample. Elements form a limited set normalized to a disjoint set so that the boundary of the disjoint set divides the space of all possible collections of features into 'legitimate' and “all others.” “All others” include signs of known attacks, anomalies and signs of unknown attacks.
