Protecting patient privacy in survival analyses.

ABSTRACT:

Objective

Survival analysis is the cornerstone of many healthcare applications in which the "survival" probability (eg, time free from a certain disease, time to death) of a group of patients is computed to guide clinical decisions. It is widely used in biomedical research and healthcare applications. However, frequent sharing of exact survival curves may reveal information about the individual patients, as an adversary may infer the presence of a person of interest as a participant of a study or of a particular group. Therefore, it is imperative to develop methods to protect patient privacy in survival analysis.

Materials and methods

We develop a framework based on the formal model of differential privacy, which provides provable privacy protection against a knowledgeable a
