Preserving Anonymity and Privacy in Electronic Healthcare — A Necessity or Paranoia?

Speaker: Daniel Slamanig
Date, Time: Mon, 14 Dec 2009 15:00

In recent years eHealth and ubiquitous healthcare have gained significant attention in the scientific community as well as among practitioners. Basically, the idea behind these concepts is to collect and store health related information (anywhere) such that they can be accessed time and location independently by authorized parties to improve medical treatment processes. One major piece in this puzzle is the so called Personal Health Record (PHR). These systems enable individuals to efficiently manage and share their health related data with other parties. However, having in mind that these data are highly sensitive and data-theft scandals are cumulating, security related issues are central to these systems. Surprisingly, many currently deployed solutions fail to provide adequate security concepts.

In this talk we will firstly highlight security and privacy issues in this context and secondly discuss approaches to realize them. In particular, we will present attack scenarios as well as adversarial models and argue that classical models do not fully cover realistic attacks. Interestingly, some up to now theoretical cryptographic techniques to realize e.g. anonymous authentication, anonymous transactions resp. anonymous service usage are well suited in this context. These techniques will be discussed and we will show how they can be used to realize adequate privacy protection.
