  • Abstract:

    Nowadays huge amounts of personal data are regularly collected in all spheres of life, creating interesting research opportunities but also a risk to individual privacy. We consider the problem of protecting confidentiality of records used for statistical analysis, while preserving as much of the data utility as possible. Since OLAP cubes are often used to store data, we formulate a combinatorial problem that models a procedure to anonymize 2-dimensional OLAP cubes. In this talk we present a parameterised approach to this problem.
