Data Privacy

Privacy Preserving Data Mining (PPDM)

Statistical Disclosure Control (SDC)


Integral Privacy: Integral privacy is privacy model related to the computation of a function. So, it competes with differential privacy. In this case, given a function or query f we expect f(X) to be a value that does not allow to infer information on the elements of X.

Integral privacy (informal definition):

``A model is integrally private if the set of possible generators of this model is large and their intersection is not empty''

Our publications: Integral privacy. We have proposed this privacy model and shown how to build integrally private computations (e.g., decision trees, statistics, regression).

    • This is the paper in which we defined integral privacy. The original definition considered changes on databases and how to avoid that these changes are detected when we disclose the model.
  • Senavirathne, N., Torra, V. (2019) Integrally private model selection for decision trees, Computers and Security 83: 167-181. paper / DOI
    • This paper explains how to build decision trees that are integrally private. We show that when selecting a decision tree, we can select one that is not only accurate but also recurrent. This makes the decision tree stronger from a privacy perspective. This is so because there are a large number of datasets that can generate the selected tree. The paper shows that accuracy and recurrency (and thus privacy) can both taken into account.

    • This paper studies the case of some statistics. We explain how to compute different types of statistics that are compliant with the definition of integral privacy.
  • Senavirathne, N., Torra, V. (2018) Approximating Robust Linear Regression With An Integral Privacy Guarantee, Proc. PST 2018: 1-10. paper (DOI) here
    • We studied linear regression from an integral privacy perspective. We work with robust regression.

    • In statistical and machine learning, and when comparing data protection procedures, it is usual to compare models with respect to accuracy. In this work we consider a different approach. Distance between a pair of models is based on how these models might have been generated. So, if two different models are generated using two databases that only differ in one record, they will be similar and if they are generated by two completely different databases, they will be dissimilar.
