Abstract
A method is provided for watermarking a machine learning model. A sequence of bits is generated. The sequence of bits may be text characters divided into chunks. A selected plurality of input samples from training data is divided into subsets of input samples. All of the input samples of each subset of the subsets of input samples are labeled with a same first label in a problem domain of the ML model. Each chunk is combined with a subset of the labeled subsets to produce a plurality of labeled trigger samples. Each trigger sample of each set of the plurality of sets is relabeled to have a second label different from the first label and in the problem domain to produce a relabeled set of trigger samples. The ML model is trained with the training data and the relabeled trigger samples to produce a watermarked ML model.
