Continual Learning With Participation Privacy: An Auditable Buffering-Aggregation Recipe

arXiv:2607.07209v1 Announce Type: cross Abstract: Modern federated and streaming learning systems often release intermediate models, so privacy must hold for the full trajectory under adaptive interaction. Motivated by participation privacy, we study single-edit neighboring user streams, where one insertion/deletion shifts all subsequent updates and defeats standard Hamming-neighbor continual-release analyses. We give an auditable modular recipe. A randomized buffering wrapper emits bins of size $[U,2U]$, reducing single-edit streams to a Hamming-style per-bin update stream with explicit backl

Why this matters
Why now

As federated and streaming learning systems become more prevalent, the need to ensure data privacy throughout the entire model development trajectory, especially against adaptive attacks, is critical.

Why it’s important

This research provides a framework for auditable privacy assurances in continual learning, which is essential for deploying AI systems in sensitive applications and maintaining public trust.

What changes

The development of an auditable buffering-aggregation recipe offers a more robust method for protecting individual participation privacy in dynamic AI environments, moving beyond standard Hamming-neighbor analyses.

Winners
  • · AI developers
  • · Organizations handling sensitive data
  • · Privacy-focused AI platforms
Losers
  • · Adversaries exploiting data leakage
