Redfield_​Privacy_​extension_​example

The workflow gives an example of how the Privacy extension nodes are used for data anonymization and risk assessment.

A simple example is shown how to anonymize «personal» data taken from computer game FIFA19. Multiple anonymization techniques are used: hashing, generalization, masking etc. In the end of the workflow there goes risk assessment and comparison of original and anonymized data sets. For risk analysis the distinction and separation of quasi-identifiers and different attacker models are estimated.
