A barometer for state surveillance

 

To ensure the freedom and security of citizens through crime prevention measures, surveillance on the part of the state appears indispensable. But how far should and may it go? Already in the 1990s, when legislators first introduced a mandatory count of state surveillance measures in telecommunications, the results became the subject of heated debate in the press.

In the meantime, both our communication behavior and the threats have changed. To what extent do the authorities access our personal data today? What can they do, what do they do and what should they achieve?

In his lecture, Poscher outlined a scientific method for creating a so-called surveillance barometer. The objective is to gain a systematic overview of all surveillance measures by security authorities. The findings should make social discussions more objective and simplify legislation – not only in Germany, but throughout the European Union.
