Big Data

What does Big Data?

Big Data (German: Massendaten) refers to the handling of a large amount of data. This often refers to the evaluation of large data sets using mathematical processes (so-called algorithms) in order to derive certain results and, if necessary, make forecasts. Data processing is often carried out with the help of artificial intelligence, i.e. with self-learning algorithms. Due to the Processing enormous amounts of data, the application of Big Data very difficult under data protection law. The topic is very complex overall, but here too there must be a legal basis and the central data protection principles must be observed. With the Processing In addition, it is problematic that the linking of actually unstructured data can create a new context and thus a reference to a specific person. In addition, big data analysis can be used to draw conclusions about the future behaviour of those affected, meaning that there is a risk of stigmatization or "prejudgement".

Practical example

Within the scope of Big Data uses a company personal data for targeted advertising measures and obtains the necessary consent in advance.
