    Controlled tabular adjustment (CIA) is a relatively new protection technique for tabular data protection. CTA formulates a mixed integer linear programming problem, which is challenging for tables of moderate size. Even ...
  • On using an improved Benders method for cell suppression 

    Baena, Daniel; Castro Pérez, Jordi; Frangioni, Antonio (2017)
    Text en actes de congrés
    Accés obert
    The cell suppression problem (CSP) is one of the most widely applied methods for tabular data protection. Given a set of primary cells to be protected, CSP aims at finding a set of secondary cells to be additionally removed ...
  • Stabilized Benders methods for large-scale combinatorial optimization, with appllication to data privacy 

    Baena, Daniel; Castro Pérez, Jordi; Frangioni, Antonio (2017-10-24)
    Report de recerca
    Accés obert
    The Cell Suppression Problem (CSP) is a challenging Mixed-Integer Linear Problem arising in statistical tabular data protection. Medium sized instances of CSP involve thousands of binary variables and million of continuous ...
  • Symmetric vs asymmetric protection levels in SDC methods for tabular data 

    Baena, Daniel; Castro Pérez, Jordi; González Alastrué, José Antonio (Springer, 2018-09)
    Article
    Accés obert
    Protection levels on sensitive cells—which are key parameters of any statistical disclosure control method for tabular data—are related to the difficulty of any attacker to recompute a good estimation of the true cell ...
  • Using a Mathematical Programming Modeling Language for Optimal CTA 

    Castro Pérez, Jordi; Baena, Daniel (Springer Berlin / Heidelberg, 2008-09-30)
    Capítol de llibre
    Accés restringit per política de l'editorial
    Minimum-distance controlled tabular adjustment methods (CTA) have been formulated as an alternative to the cell suppression problem (CSP) for tabular data. CTA formulates an optimization problem with fewer variables and ...
