Modeling projections in microaggregation
Nin Guerrero, Jordi; Torra i Reventós, Vicenç (2008)
Text en actes de congrés
Accés obertMicroaggregation is a method used by statistical agencies to limit the disclosure of sensitive microdata. It has been proven that microaggregation is an NP-hard problem when more than one variable is microaggregated at the ... -
On method-specific record linkage for risk assessment
Nin Guerrero, Jordi; Herranz Sotoca, Javier; Torra i Reventós, Vicenç (2007)
Text en actes de congrés
Accés obertNowadays, the need for privacy motivates the use of methods that permit us to protect a microdata file both minimizing the disclosure risk and preserving the statistical utility. Nevertheless, research is usually focused ... -
On the disclosure risk of multivariate microaggregation
Nin Guerrero, Jordi; Herranz Sotoca, Javier; Torra i Reventós, Vicenç (Elsevier Science Ltd., 2008-07-22)
Article
Accés restringit per política de l'editorialThe aim of data protection methods is to protect a microdata file both minimizing the disclosure risk and preserving the data utility. Microaggregation is one of the most popular such methods among statistical agencies. ... -
On the use of aggregation operators for location privacy
Valls, Aïda; Nin Guerrero, Jordi; Torra i Reventós, Vicenç (2009)
Text en actes de congrés
Accés restringit per política de l'editorialNowadays, the management of sequential and temporal data is an increasing need in many data mining processes. Therefore, the development of new privacy preserving data mining techniques for sequential data is a crucial ... -
Record linkage for database integration using fuzzy integrals
Nin Guerrero, Jordi; Torra i Reventós, Vicenç (Wiley InterScience, 2008-06-01)
Article
Accés restringit per política de l'editorialGiven two-data databases, record linkage algorithms try to establish which records of these files contain information on the same individual. Standard record linkage algorithms assume that both files are described using ... -
Towards the evaluation of time series protection methods
Nin Guerrero, Jordi; Torra i Reventós, Vicenç (2009-02-04)
Article
Accés restringit per política de l'editorialThe goal of statistical disclosure control (SDC) is to modify statistical data so that it can be published without releasing confidential information that may be linked to specific respondents. The challenge for SDC is to ... -
Towards the use of OWA operators for record linkage
Nin Guerrero, Jordi; Torra i Reventós, Vicenç (2005)
Text en actes de congrés
Accés obertRecord linkage is used to establish links between those records that while belonging to two different files correspond to the same individual. Classical approaches assume that the two files contain some common variables, ...
