Keynote: Differentially Private Measurements in Advertising
Pasin Manurangsi (Invited Speaker) Digital advertising is a critical component of the internet and is powered by large-scale data analytics and machine learning models; privacy concerns around these are on the rise. In the past few years, numerous proposals have been put forth to address such concerns. Many of these proposals aim to achieve formal guarantees of differential privacy. In this talk, we will review the setting, discuss high-level ideas of proposed solutions and describe the main research challenges in the space, with focus on measurements. |

Keynote: The Ever-evolving Intersection of Statistics and Privacy
Jeremy Seeman (Invited Speaker) The challenge of mitigating disclosure risks associated with sensitive data and statistical analyses is a long-standing topic in statistics, yet many researchers and partitioners remain unfamiliar with potential ideas and solutions offered by statistical disclosure control (SDC) methodologies. Differential privacy (DP) has become a leading framework, providing mathematically verifiable privacy guarantees in a transparent manner to support the release of summary statistics and synthetic data. In this talk, I will discuss the shared statistical foundations of both SDC and DP, offering a personal and historical perspective. We will journey through how we arrived at the current state and consider the future of statistical data privacy. |

Keynote: Concurrent Composition of Interactive Differential Privacy
Wanrong Zhang (Invited Speaker) We initiate a study of the composition properties of interactive differentially private mechanisms. An interactive differentially private mechanism is a possibly stateful algorithm that allows an analyst to adaptively ask queries about a sensitive dataset. We focus on *concurrent* composition, where an adversary can arbitrarily interleave its queries to several interactive differentially private mechanisms, which may be feasible when differentially private query systems are deployed in practice. We prove that the main composition theorems for non-interactive differentially private mechanisms extend to the concurrent composition of interactive differentially private mechanisms. Our theorems cover the cases when differential privacy is measured using the hypothesis testing framework of f-DP, which captures standard ($\epsilon,\delta$)-DP as a special case, or using Renyi divergence of fixed order (Renyi DP). Our proof for the case of f-DP works by showing that every interactive f-DP mechanism can be simulated, on any pair of adjacent datasets, by an interactive post-processing of a non-interactive f-DP mechanism. |

Differential privacy (DP) is the leading framework for data analysis with rigorous privacy guarantees. In the last 15 years, it has transitioned from the realm of pure theory to large scale, real world deployments. The use of differential privacy by the U.S. Census Bureau and increasing industry adoption has increased its public profile and presents new questions for social scientists and policymakers.
Differential privacy is an inherently interdisciplinary field, drawing researchers from a variety of academic communities including machine learning, statistics, security, theoretical computer science, databases, and law. The combined effort across a broad spectrum of computer science is essential for differential privacy to realize its full potential. To this end, this workshop aims to stimulate discussion among participants about both the state-of-the-art in differential privacy and the future challenges that must be addressed to make differential privacy more practical.
Specific topics of interest for the workshop include (but are not limited to):
The OpenDP Community Meeting 2023 will be taking place the same week as TPDP in Boston, on Friday, September 29. OpenDP will also be hosting a reception at 4pm on Thursday, September 28, after the conclusion of TPDP. We encourage participants to consider attending the community meeting!

The goal of TPDP is to stimulate the discussion on the relevance of differentially private data analyses in practice. For this reason, we seek contributions from different research areas of computer science and statistics.
Authors are invited to submit a short abstract (4 pages maximum, with unlimited references and appendices (only read at reviewer's discretion)) of their work. Submissions are single-blind (non-anonymized), and there is no prescribed style file (though authors should be considerate of reviewers in their selection).
Submissions will undergo a lightweight review process and will be judged on originality, relevance, interest and clarity. Submission should describe novel work or work that has already appeared elsewhere but that can stimulate the discussion between different communities at the workshop. Accepted abstracts will be presented at the workshop either as a talk or a poster.
The workshop will not have formal proceedings and is not intended to preclude later publication at another venue. In-person attendance is encouraged, though there will be some limited means for work by non-attending authors to be featured at TPDP 2023.
Selected papers from the workshop will be invited to submit a full version of their work for publication in a special issue of the Journal of Privacy and Confidentiality.
