    The Binary Tree Mechanism is Optimal for Approximate Differentially Private Continual Counting

    Konstantina Bairaktari, Kasper Green Larsen

    cs.DS · cs.CR · cs.LG

    Private continual counting is a fundamental problem in differential privacy: given a binary stream of length $n$, where each $1$ corresponds to the contribution of one individual, the goal is to release all running counts while protecting the privacy of each individual. The standard algorithm is the binary tree mechanism, whose Gaussian-noise variant achieves expected $\ell_\infty$ error proportional to $\log^{3/2} n$ for approximate...
