NNSplitter: An Active Defense Solution for DNN Model via Automated Weight Obfuscation

1 code implementation28 Apr 2023 Tong Zhou, Yukui Luo, Shaolei Ren, Xiaolin Xu

In this work, we propose an active model IP protection scheme, namely NNSplitter, which actively protects the model by splitting it into two parts: the obfuscated model that performs poorly due to weight obfuscation, and the model secrets consisting of the indexes and original values of the obfuscated weights, which can only be accessed by authorized users with the support of the trusted execution environment.
