k-Anonymity (+ l-Diversity, t-Closeness)
← BackQuasi-Identifiers (QIs)
Select columns that, when combined, could identify individuals (e.g., Age + City).
l-Diversity (intuitive):
Each QI group must include at least l distinct values of a
sensitive attribute. Prevents groups where everyone shares the same
sensitive value (e.g., all “Cancer”).
t-Closeness (intuitive):
Each QI group’s distribution for a sensitive attribute should be close
to the overall dataset’s distribution. This demo uses Total Variation
Distance and requires it ≤ t.
Sensitive Attribute Picker
Pick which attributes are sensitive. Use the filter to quickly find columns. Only picked ones appear below with settings.
