Josep M. Mateo-Sanz, Josep Domingo-Ferrer, Francesc Sebé
2005 Data mining and knowledge discovery  
We propose in this paper to use probabilities to define bounded information loss measures for continuous microdata.  ...  Inference control for protecting the privacy of microdata (individual data) should try to optimize the tradeoff between data utility (low information loss) and protection against disclosure (low disclosure  ...  Acknowledgments Thanks go to Jordi Castellà for his help in preparing the web form http://vneumann.etse.urv.es/SDC/measures.  ...

Microdata Protection [chapter]

V. Ciriani, S. De Capitani di Vimercati, S. Foresti, P. Samarati
2007 Advances in Information Security  
Information loss is the amount of information that exists in the original microdata and because of the protection technique does not occur in protected microdata.  ...  The information loss measure uses the conditional probability (the probability of a value in the original microdata, once the value in the protected microdata is given).  ...

Synthetic Business Microdata

Chien-Hung Chien, Alan Hepburn Welsh, John D Moore
2020 Journal of Privacy and Confidentiality  
Enhancing microdata access is one of the strategic priorities for the Australian Bureau of Statistics (ABS) in its transformation program.  ...  This means the existing microdata protection techniques such as information reduction or perturbation may not be as effective as for household microdata.  ...  However, it is often difficult to quantify the amount of information loss or level of protection achieved using confidentialised input approaches.  ...

Statistical Disclosure Limitation: New Directions and Challenges

Natalie Shlomo
2018 Journal of Privacy and Confidentiality  
There is now more recognition of the need for perturbative methods to protect the confidentiality of data subjects.  ...  In particular, inferential disclosure is the main disclosure risk of concern and encompasses the traditional types of disclosure risks based on identity and attribute disclosures.  ...  One of the first approaches to quantify disclosure risk in survey microdata was by record linkage (distance-based or probabilistic) where the confidentialized data was matched back to the original data  ...

Survey on Privacy-Preserving Techniques for Data Publishing [article]

Tânia Carvalho, Nuno Moniz, Pedro Faria, Luís Antunes
2022 arXiv   pre-print
We present existing privacy-preserving techniques used in microdata de-identification, privacy measures suitable for several disclosure types and, information loss and predictive performance measures.  ...  However, de-identified data usually results in loss of information, with a possible impact on data analysis precision and model predictive performance.  ...  In general, information loss is measured during the generalisation process.  ...

Post-Masking Optimization of the Tradeoff between Information Loss and Disclosure Risk in Masked Microdata Sets [chapter]

Francesc Sebé, Josep Domingo-Ferrer, Josep Maria Mateo-Sanz, Vicenç Torra
2002 Lecture Notes in Computer Science  
Previous work by these authors has been directed to measuring the performance of microdata masking methods in terms of information loss and disclosure risk.  ...  The technique proposed can also be used for synthetic microdata generation and can be extended to preservation of all moments up to m-th order, for any m.  ...  This is a substantial step forward in optimizing the tradeoff between information loss and disclosure risk in microdata protection.  ...

Ordinal, Continuous and Heterogeneous k-Anonymity Through Microaggregation

Josep Domingo-Ferrer, Vicenç Torra
2005 Data mining and knowledge discovery  
k-Anonymity is a useful concept to solve the tension between data utility and respondent privacy in individual data (microdata) protection.  ...  However, the generalization and suppression approach proposed in the literature to achieve k-anonymity is not equally suited for all types of attributes: (i) generalization/suppression is one of the few  ...  Acknowledgments Francesc Sebé's help in obtaining the results reported for continuous data is gratefully acknowledged. Comments by William Winkler were also particularly useful to improve this paper.  ...

Providing Data With High Utility And No Disclosure Risk For The Public and Researchers: An Evaluation By Advanced Statistical Disclosure Risk Methods

Matthias Templ
2014 Austrian Journal of Statistics  
It is shown that the application of few selected anonymisation methods leads to well-protected anonymised data with high data utility and low information loss.  ...  The research on SDC methods becomes more and more important in the last years because of an increase of the awareness on data privacy and because of the fact that more and more data are provided to the  ...  Measuring disclosure risk Measuring risk in an microdata set is of course of great concern when having to decide on whether a microdata set is safe to be released.  ...

Releasing Microdata: Disclosure Risk Estimation, Data Masking and Assessing Utility

Natalie Shlomo
2010 Journal of Privacy and Confidentiality  
Statistical Agencies need to make informed decisions when releasing sample microdata from social surveys with respect to the level of protection required in the data and the mode of access.  ...  These decisions should be based on objective quantitative measures of disclosure risk and data utility.  ...  Shlomo, 2007 and Shlomo and Young, 2006 describe the use of such measures for assessing information loss in perturbed statistical data.  ...

Statistical Disclosure Risk: Separating Potential and Harm

Chris Skinner
2012 International Statistical Review  
Statistical agencies are keen to devise ways to provide research access to data while protecting confidentiality.  ...  We argue in Section 2.2 that, in the context of many official confidentiality statements, it is appropriate that the probability of disclosure refers to true disclosure.  ...  Introduction The challenge of devising ways to provide researchers with access to microdata and other statistical outputs while protecting confidentiality continues to be the subject of intense interest  ...
