Privacy 3.0 := Data Minimization + User Control + Contextual Integrity

It is argued that Privatheit 3.0 should be a combination of (1) Data minimization, (2) User control of personal information disclosure, and (3) Contextual integrity.

Abstract

Abstract Over the last two decades, privacy has been fading away. Some people have even stated: You have zero privacy — get over it! As privacy researchers, we are not willing to accept this statement. Therefore, we analyze the causes for this fading away of privacy, and develop a set of approaches to preserve or even regain privacy. We argue that Privacy 3.0 should be a combination of (1) Data minimization, (2) User control of personal information disclosure, and (3) Contextual integrity. Data minimization is one of the main motivations for the development of privacy-enhancing technologies, which aim to limit collection and processing of personal data by data controllers. User control of personal information disclosure supports users in deciding which personal information is released to whom and in which situation. Contextual integrity provides a new quality of privacy by making the original context in which particular personal data have been generated easily accessible to all entities that are aware of that particular personal data.
