Enhancing privacy by design from a developer's perspective

This work proposes a pragmatic approach towards refining as well as complementing Ann Cavoukians seven principles of Privacy by Design. In an analysis of the principles definitions, practical handicaps as well as essential complementary claims are pointed out. Based on these insights the authors come up with a more consistent and pragmatic definition of Privacy by Design governed by seven requirements. A practical application of this new definition of Privacy by Design is demonstrated by means of an example scenario in the context of video surveillance. It is shown that by applying the principles of the new definition to the redesign process of a conventional surveillance system, a significantly more privacy-aware intelligent surveillance system can be be obtained.
