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.
