Abstract
A method for measuring the sensitivity of a classifier for digital images against adversarial attacks. The classifier includes at least one neural network. The method includes: providing a digital image for which the sensitivity is to be measured; providing a generator that is trained to map elements of a latent space to a realistic image; obtaining, according to a set of parameters, an element of the latent space; mapping, using the generator, this element to a disturbance in the space of realistic images; perturbing the digital image with this disturbance; determining, using the classifier, a classification result for the perturbed image; determining, from the classification result, the impact of the disturbance on the classification result; optimizing the set of parameters to maximize this impact; and determining, based at least in part on the maximum impact, the sensitivity of the classifier.
