Sören Preibusch (2014), standing

In January 2015, I joined Google as a User Experience Researcher in Mountain View, California. Before that, I was a post-doctoral researcher at Microsoft Research, Cambridge. In the tradition of behavioural economics, I design and deploy large-scale lab experiments, field studies and log analyses to quantitatively describe consumers' privacy concerns and behaviours. I observe privacy choices in major Web activities (shopping and search) to measure the value of privacy and of privacy-enhancing features. I study measurement techniques for privacy concerns and use statistical methods to assess their diversity, temporal evolution and variation across countries. Through the methodological and material results of my research, I advance the state of the art and provide business intelligence to engineering teams, legal and marketing.

Key Facts on Privacy Negotiations

Problem statement - Take-it-or-leave-it offers are the current corporate and regulatory practice: privacy policies are far from personalised. Yet, consumers value privacy quite differently and the worries they attach to particular data items vary. As a result, many frustrated and disappointed customers cancel online purchases or avoid online interaction.

Privacy Negotiations - In Privacy Negotiations, consumers and service providers establish, maintain, and refine privacy policies as individualised agreements through the ongoing choice amongst service alternatives.

Incentivised Privacy Negotiations - In incentivised privacy negotiations, the transaction partners may additionally bundle the personal information collection and processing schemes with monetary or non-monetary rewards.

Ethics of Privacy Negotiations - Privacy negotiations do not contravene the human right to informational self-determination. Consumers are not rewarded for renouncing their privacy, but agree on a price for personal information, which is an economic good. As a privacy-enhancing technology, incentivised privacy policy negotiations lift this price above null compensation.
