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.

On the (In)Feasibility of Attribute Inference Attacks on Machine Learning Models

no code implementations12 Mar 2021 Benjamin Zi Hao Zhao, Aviral Agrawal, Catisha Coburn, Hassan Jameel Asghar, Raghav Bhaskar, Mohamed Ali Kaafar, Darren Webb, Peter Dickinson

In this paper, we take a closer look at another inference attack reported in literature, called attribute inference, whereby an attacker tries to infer missing attributes of a partially known record used in the training dataset by accessing the machine learning model as an API.
