Practical, Private Assurance of the Value of Collaboration

no code implementations4 Oct 2023 Hassan Jameel Asghar, Zhigang Lu, Zhongrui Zhao, Dali Kaafar

In this work, we construct an interactive protocol for this problem based on the fully homomorphic encryption scheme over the Torus (TFHE) and label differential privacy, where the underlying machine learning model is a neural network.

VeriDIP: Verifying Ownership of Deep Neural Networks through Privacy Leakage Fingerprints

no code implementations7 Sep 2023 Aoting Hu, Zhigang Lu, Renjie Xie, Minhui Xue

(2) We introduce a novel approach using less private samples to enhance the performance of ownership testing.

A Differentially Private Framework for Deep Learning with Convexified Loss Functions

no code implementations3 Apr 2022 Zhigang Lu, Hassan Jameel Asghar, Mohamed Ali Kaafar, Darren Webb, Peter Dickinson

Under a black-box setting, based on this global sensitivity, to control the overall noise injection, we propose a novel output perturbation framework by injecting DP noise into a randomly sampled neuron (via the exponential mechanism) at the output layer of a baseline non-private neural network trained with a convexified loss function.

Data and Model Dependencies of Membership Inference Attack

1 code implementation17 Feb 2020 Shakila Mahjabin Tonni, Dinusha Vatsalan, Farhad Farokhi, Dali Kaafar, Zhigang Lu, Gioacchino Tangari

Our results reveal the relationship between MIA accuracy and properties of the dataset and training model in use.

Fairness Inference Attack +2
