What is Profiling?
A Common Use Case:
Profiling is applying algorithms for segmentation, categorization and classification of individuals and groups.
Profiling - a Definition
Profiling is a technique to automatically process personal and non-personal data, aimed at developing predictive knowledge from the data in the form of constructing profiles that can subsequently be applied as a basis for decision-making.
Ferraris et al. 2013.
Profiling is great!?
personalization simplifies our world in times of information overload. Personalized news feed, shopping suggestions, identification of potential terrorists
many profiling systems even work without PII - so no privacy concerns!?

What is Privacy?
Dimensions of Privacy
Locational ~ the right to be let alone
Informational ~ the right to know what, why, when and by whom
Decisional ~ the right to make decisions on your own

My home is my castle - but rooms can also be virtual
The right to informational self-determination guarantees* the power for each individual to decide on her own what personal data she releases and for what purpose. (Supreme Court of German, 1983)
the freedom to live your life, act and behave like you want requires privacy. It enables you to make decisions without unwanted influences.
