Anonymisation of geographical distance matrices via Lipschitz embedding
We propose a new anonymisation method for the release of geographical distances between records of a microdata file—for example patients in a medical database. Expand

Local differential privacy: Elbow effect in optimal density estimation and adaptation over Besov ellipsoids
We address the problem of non-parametric density estimation under local differential privacy under the additional constraint that only privatised data are allowed to be published and available for inference. Expand

Erstversorgung von Neugeborenen
In den 2000 Akutkrankenhausern der Bundesrepublik Deutschland gibt es etwa 1100 gynakologisch-geburtshilfliche Abteilungen. Diesen stehen 300 Kinderkliniken gegenuber, d.h.esist nur bei in einemExpand
Pointwise adaptive kernel density estimation under local approximate differential privacy
We show that taking the average of private kernel density estimators from $n$ different data owners attains the optimal rate of convergence if the bandwidth parameter is correctly specified. Expand
