Claim 8:
9. One or more computer readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
obtaining reference weight information of a reference neural network model that is not embedded with watermark information;
obtaining target weight information of a target neural network model that is embedded with partial watermark information, the reference neural network model and the target neural network model having a same structure; and
using the reference weight information and the target weight information as a training set to train a detection neural network model, and adjusting a model training method of the target neural network model according to distinguishability data of the reference weight information and the target weight information outputted by the detection neural network model, and obtaining a target neural network model that satisfies a watermark information hiding condition, wherein using the reference weight information and the target weight information as the training set to train the detection neural network model comprises:
using the reference weight information and the target weight information as the training set, and updating the weight information of the detection neural network model according to a model loss function of the detection neural network model.
