On the Optimal Number of Grids for Differentially Private Non-Interactive K-Means Clustering

On the Optimal Number of Grids for Differentially Private Non-Interactive K-Means Clustering Authors: Gokularam M, Anshoo Tandon Differentially private K-means clustering enables releasing cluster centers derived from a dataset while protecting the privacy of the individuals. Non-interactive clustering techniques based on privatized histograms are attractive because the released data synopsis can be reused for other downstream tasks without additional privacy loss. …

SKALD: Scalable K-Anonymisation for Large Datasets 

SKALD: Scalable K-Anonymisation for Large Datasets  Authors:K. Reddy, N. Chakraborty, A. Dharmavaram, A. Tandon Data privacy and anonymisation are critical concerns in today’s data-driven society, particularly when handling personal and sensitive user data. Regulatory frameworks worldwide recommend privacy-preserving protocols such as k-anonymisation to de-identify releases of tabular data. Available hardware resources provide an upper bound on the maximum size of …

Improving the Privacy Loss Under User-Level DP Composition for Fixed Estimation Error

Improving the Privacy Loss Under User-Level DP Composition for Fixed Estimation Error Authors:V. A. Rameshwar and A. Tandon This paper considers the private release of statistics of several disjoint subsets of a datasets. In particular, we consider the epsilon-user-level differentially private release of sample means and variances of sample values in disjoint subsets of a dataset, in a potentially sequential manner. …

ℓ, 𝛿)-Diversity: Linkage-Robustness via a Composition Theorem

ℓ, 𝛿)-Diversity: Linkage-Robustness via a Composition Theorem Authors:V. A. Rameshwar and A. Tandon In this paper, we consider the problem of degradation of anonymity upon linkages of anonymized datasets. We work in the setting where an adversary links together tgeq 2 anonymized datasets in which a user of interest participates, based on the user’s known quasi-identifiers, which motivates the use of ell-diversity as …

Bounding User Contributions for User-Level Differentially Private Mean Estimation

Bounding User Contributions for User-Level Differentially Private Mean Estimation Authors: V. Arvind Rameshwar (IIT Madras) and Anshoo Tandon We revisit the problem of releasing the sample mean of bounded samples in a dataset, privately, under user-level ε-differential privacy (DP). We aim to derive the optimal method of preprocessing data samples, within a canonical class of processing strategies, in terms of the …
