Abstract: A method for securing a genuine machine learning model against adversarial samples includes receiving a sample, as well as receiving a classification of the sample using the genuine machine learning model or classifying the sample using the genuine machine learning model. The sample is classified using a plurality of backdoored models, which are each a backdoored version of the genuine machine learning model. The classification of the sample using the genuine machine learning model is compared to each of the classifications of the sample using the backdoored models to determine a number of the backdoored models outputting a different class than the genuine machine learning model. The number of the backdoored models outputting a different class than the genuine machine learning model is compared against a predetermined threshold so as to determine whether the sample is an adversarial sample.
