Claim 12:
13. The one or more computer readable media according to claim 9, wherein adjusting the model training method of the target neural network model according to the distinguishability data of the reference weight information and the target weight information outputted by the detection neural network model comprises:
obtaining a regular term used for hiding the watermark information according to the distinguishability data;
adding the regular term used for hiding the watermark information on a basis of a corresponding model loss function when a conventional training set is used to train the target neural network model and a regular term used for embedding the watermark information, and obtaining a target loss function corresponding to the target neural network model; and
updating the target weight information of the target neural network model based on the target loss function.
