Abstract

Deep Neural Networks (DNNs) have become a powerful tool for a wide range of problems. Yet recent work has shown an increasing variety of adversarial samples that can fool them. Most existing detection mechanisms impose significant costs, either by using additional classifiers to spot adversarial samples, or by requiring the DNN to be restructured. In this presentation, we introduce a novel defense, Taboo Trap. We explain how one should go about training networks with Taboo Trap and show that it allows the user to perform adversarial sample attribution and cryptography-like operations. Taboo Trap requires no additional computation in the run time, making it the first defence that can be used in the constrained devices.
