Abstract: A method of digitally watermarking a neural network, implemented by an electronic device, the neural network being stored within a data structure including blocks of parameters. The method includes, for a current parameter block consisting of at least N parameters representing real numbers, obtaining a message including N bits, at least N iterations of a parameter modification operation within the current block, including obtaining a current parameter, from among the at least N parameters of the current parameter block, and updating the value of a predetermined index bit of the current parameter as a function of a bit in the message.

Abstract: A method for encoding a digital signature of a neural network, implemented by an electronic device, the neural network being stored within a data structure including blocks of parameters. The method includes, for a current block of parameters including at least M parameters representing real numbers: an operation of acquiring a signature binary image from the digital signature including a set of bits extracted from parameters of the current block of parameters, and an operation of combining the signature binary image with a reference binary image delivering a coded binary image.
