Privacy by design: a matter of choice
Abstract
Privacy by design is often praised by lawyers as an essential step towards better privacy protection: in a world where privacy is more and more jeopardized by new information and communication technologies (ICT), the growing view is that part of the remedy should come from the technologies themselves. On the technological front, privacy enhancing technologies (PETs) have been an active research topic in computer science during the last decades and a variety of techniques have been proposed (including anonymizers, identity management systems, privacy proxies, encryption mechanisms, filters, etc.). One must admit however that the take-up of most of these techniques by consumers is still rather limited. The goal of this chapter is to review this gap between a toolset of available technologies and the still unrealized promises of privacy by design.
