Claim 2:
3. The method according to claim 1, wherein updating the weight information of the target neural network model according to the target watermark embedded data provided by the embedded neural network model to obtain the target neural network model embedded with the target watermark information comprises:
inputting first weight information of the target neural network model into the embedded neural network model;
obtaining first target watermark embedded data outputted by the embedded neural network model, the first target watermark embedded data including watermark information extracted from the first weight information of the target neural network model by the embedded neural network model;
terminating the training of the embedded neural network model if the first target watermark embedded data indicates that the target watermark information has been embedded in the first weight information, and determining that a target neural network model corresponding to the first weight information as the target neural network model embedded with the target watermark information.
