The dummy-point mechanism addresses the privacy loss caused by batch size leakage and truncation, and does not change the noise calibration logic of DP-SGD itself.

UnverifiedThe injection of dummy points yields subsampling-style privacy amplification for the count release, so that the expected number of required dummy points can be asymptotically smaller than what is needed to directly privatize the batch size with non-negative noise (sensitivity 1).75% similarUnverifiedPrivileged information leakage remains an unsolved problem for SpatialOPSD; the current mitigation is masking and likelihood-free regularization in repeated perception distillation, but this only controls rather than eliminates it.70% similarUnverifiedThe privacy amplification effect of DP-SGD relies on the premise that the batch size is not leaked.70% similarVerifiedDP-SGD is a mechanism for achieving differential privacy in stochastic gradient descent, implemented by clipping per-sample gradients and then adding Gaussian noise.68% similarUnverifiedThe coordinated vulnerability disclosure (CVD) mechanism aims to shorten the patch gap and reduce information asymmetry, but early leaks can still occur in practice.66% similar
