Researchers have developed a new method called Spiking Domain Model Inversion (SDMI) to analyze privacy leakage in memristive spiking neural networks (SNNs). This technique combines Expectation over Transformation (EOT) with surrogate gradients to optimize inputs through stochastic analog behavior and non-differentiable spiking dynamics. Experiments across four datasets revealed that hardware variability does not inherently preserve privacy, as reconstruction fidelity can increase with neuron-threshold perturbations, while weight noise may reduce leakage. The findings indicate that model inversion leakage in memristive SNNs is dependent on the hardware state and cannot be solely inferred from model accuracy. AI
