Embodiment Construction

[0038] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] Neural network technology has outstanding performance in image classification, object detection, semantic segmentation, etc., and plays a vital role in fields such as machine vision. Training a neural network model with excellent performance often needs to be based on massive high-quality image samples and high-performance GPU computing clusters. Therefore, in order to ensure that the trained neural network model is not copied, redistributed or illegally used, neural Network models add watermarks or encrypt them.

[0040] In related technologies, the technical means of encrypting the neural network model are as follows: by constructing various mapping functions, the weights of the neural network model are encoded by the function and then stored, and when the model is used, the corresponding inverse function is used to transform the stored Nu...

Abstract

The invention discloses a watermark adding method and device, electronic equipment and a storage medium, and the method comprises the steps: determining N first values included in all digits of a first secret key; n is an integer greater than or equal to 1; positioning N first weights in the neural network model; each first weight in the N first weights corresponds to one first numerical value in the N numerical values; embedding a second key as a watermark into the neural network model; wherein the second secret key is obtained by replacing a first numerical value on each digit in the first secret key with a second numerical value of the corresponding first weight on a first set digit.

Description

technical field [0001] The present application relates to the field of encryption technology, and in particular to a watermark adding method, device, electronic equipment and storage medium. Background technique [0002] Neural network technology plays a vital role in the field of machine vision. Training a neural network model with excellent performance often needs to be based on a large number of high-quality image samples and a high-performance graphics processor (GPU, Graphics Processing Unit) computing cluster. , therefore, in order to ensure that the trained neural network model is not copied, redistributed or illegally used, a watermark can be added to the neural network model. In related technologies, adding a watermark to a neural network will have a negative impact on the performance of the neural network. Contents of the invention [0003] In order to solve related technical problems, embodiments of the present application provide a watermark adding method, dev...
