Abstract

The invention belongs to the field of artificial neural network protection mechanisms, and relates to a neural network model encryption protection system and method involving domain transformation data encryption. The system comprises an encryption module; a frequency domain transformation module in the encryption module is used for transforming original input data into a two-dimensional structure, conducting domain transformation on the original input data obtained after structure transformation and transforming the original input data in the space domain into original frequency domain data in the frequency domain; a frequency domain data processing module in the encryption module is used for processing the original frequency domain data in a specific processing mode to generate encryptedfrequency domain data; and a frequency domain inverse transformation module in the encryption module is used for conducting inverse domain transformation corresponding to above-mentioned domain transformation on the encrypted frequency domain data and transforming the encrypted frequency domain data in the frequency domain into the encrypted input data in the space domain. According to the methodof achieving input data encryption through domain transformation, the concealment and the anti-attacking performance of password information are improved, and the security of a trained artificial neural network model can be improved.

Description

technical field [0001] The invention belongs to the field of artificial neural network protection mechanism, and in particular relates to a neural network model encryption protection system and method related to domain transformation data encryption. Background technique [0002] Deep learning is the main technical solution for current artificial intelligence applications. The artificial neural network model trained with deep learning technology is the result of the labor of the original developers. However, in the process of publishing and applying the artificial neural network model, its network structure and node weights will be completely exposed to the outside world. After the artificial neural network model is released and / or applied by a third party, it is easy to be copied, re-developed or modified, resulting in damage to the rights and interests of the original developer. The protection schemes applicable to artificial neural network models in the prior art mainly...
