  • Publication number: 20240370535
    Abstract: In some implementations, a secure setup is performed by a trusted third party to generate, based on an obfuscated watermark extractor, a prover key and a verifier key to prove ownership of a first machine learning model by a model owner without divulging a trigger key or a watermark corresponding to the first machine learning model. Next, the model owner of the first machine learning model generates, based on the prover key, a proof of ownership of a second machine learning model by at least determining that the obfuscated watermark extractor extracts the watermark from the second machine learning model in response to the second machine learning model being provided as a public input to the obfuscated watermark extractor. Then, the proof of ownership is verified, based on the verifier key, to acknowledge that the second machine learning model matches the first machine learning model.

  • Publication number: 20240346379
    Abstract: A computing system determines a median of a first number of mean values received from a first number of clusters, where each cluster of the first number of clients includes a first plurality of clients. Also, a threshold is determined based on the median, where the threshold applies to model updates. The median and the threshold are broadcast to all clients. Next, one or more clients that fail to provide a proof attesting that their model update is within the threshold of the median are dropped. Then, a second plurality of clients, not including the one or more dropped clients, participate in a final round of secure aggregation. Next, a final aggregate result is obtained, where the final aggregate result is based on the final round of secure aggregation. Then, one or more actions are performed based on the final aggregate result.

  • Publication number: 20240242191
    Abstract: A method may include embedding, in a hidden layer and/or an output layer of a first machine learning model, a first digital watermark. The first digital watermark may correspond to input samples altering the low probabilistic regions of an activation map associated with the hidden layer of the first machine learning model. Alternatively, the first digital watermark may correspond to input samples rarely encountered by the first machine learning model. The first digital watermark may be embedded in the first machine learning model by at least training, based on training data including the input samples, the first machine learning model. A second machine learning model may be determined to be a duplicate of the first machine learning model based on a comparison of the first digital watermark embedded in the first machine learning model and a second digital watermark extracted from the second machine learning model.

  • Publication number: 20220083865
    Abstract: A framework is presented that provides a shift in the conceptual and practical realization of privacy-preserving interference on deep neural networks. The framework leverages the concept of the binary neural networks (BNNs) in conjunction with the garbled circuits protocol. In BNNs, the weights and activations are restricted to binary (e.g., ±1) values, substituting the costly multiplications with simple XNOR operations during the inference phase. The XNOR operation is known to be free in the GC protocol; therefore, performing oblivious inference on BNNs using GC results in the removal of costly multiplications. The approach consistent with implementations of the current subject matter provides for oblivious inference on the standard DL benchmarks being performed with minimal, if any, decrease in the prediction accuracy.
