A unifying framework for differentially private sums under continual observation

M Henzinger, J Upadhyay, S Upadhyay - … of the 2024 Annual ACM-SIAM …, 2024 - SIAM
We study the problem of maintaining a differentially private decaying sum under continual
observation. We give a unifying framework and an efficient algorithm for this problem for any …

Efficient and near-optimal noise generation for streaming differential privacy

K Dvijotham, HB McMahan, K Pillutla, T Steinke… - arXiv preprint arXiv …, 2024 - arxiv.org
In the task of differentially private (DP) continual counting, we receive a stream of increments
and our goal is to output an approximate running total of these increments, without revealing …

Improved counting under continual observation with pure differential privacy

JD Andersson, R Pagh, S Torkamani - arXiv preprint arXiv:2408.07021, 2024 - arxiv.org
Counting under continual observation is a well-studied problem in the area of differential
privacy. Given a stream of updates $ x_1, x_2,\dots, x_T\in\{0, 1\} $ the problem is to …

Optimal Rates for DP-SCO with a Single Epoch and Large Batches

CA Choquette-Choo, A Ganesh, A Thakurta - arXiv preprint arXiv …, 2024 - arxiv.org
The most common algorithms for differentially private (DP) machine learning (ML) are all
based on stochastic gradient descent, for example, DP-SGD. These algorithms achieve DP …

Time-Aware Projections: Truly Node-Private Graph Statistics under Continual Observation

C Wagaman, P Jain, A Smith - 2024 IEEE Symposium on Security and …, 2024 - computer.org
Releasing differentially private statistics about social network data is challenging: one
individual's data consists of a node and all of its connections, and typical analyses are …

DPSW-Sketch: A Differentially Private Sketch Framework for Frequency Estimation over Sliding Windows

Y Wang, Y Wang, C Chen - Proceedings of the 30th ACM SIGKDD …, 2024 - dl.acm.org
The sliding window model of computation captures scenarios in which data are continually
arriving in the form of a stream, and only the most recent w items are used for analysis. In …

Adaptive Data Analysis for Growing Data

NG Marchant, BIP Rubinstein - arXiv preprint arXiv:2405.13375, 2024 - arxiv.org
Reuse of data in adaptive workflows poses challenges regarding overfitting and the
statistical validity of results. Previous work has demonstrated that interacting with data via …

Continual Counting with Gradual Privacy Expiration

JD Andersson, M Henzinger, R Pagh… - arXiv preprint arXiv …, 2024 - arxiv.org
Differential privacy with gradual expiration models the setting where data items arrive in a
stream and at a given time $ t $ the privacy loss guaranteed for a data item seen at time $(td) …

Concurrent Composition for Continual Mechanisms

M Henzinger, R Safavi, S Vadhan - arXiv preprint arXiv:2411.03299, 2024 - arxiv.org
A series of recent works by Lyu, Wang, Vadhan, and Zhang (TCC21, NeurIPS22, STOC23)
showed that composition theorems for non-interactive differentially private mechanisms …
