Mondrian Multidimensional K-Anonymity [PDF]

open access: yes22nd International Conference on Data Engineering (ICDE'06), 2006
K-Anonymity has been proposed as a mechanism for protecting privacy in microdata publishing, and numerous recoding "models" have been considered for achieving 𝑘anonymity. This paper proposes a new multidimensional model, which provides an additional degree of flexibility not seen in previous (single-dimensional) approaches. Often this flexibility leads

(α, k)-anonymity

open access: yesProceedings of the 12th ACM SIGKDD international conference on Knowledge discovery and data mining, 2006
Privacy preservation is an important issue in the release of data for mining purposes. The k-anonymity model has been introduced for protecting individual identification. Recent studies show that a more sophisticated model is necessary to protect the association of individuals to sensitive information.

k-ANONYMITY: A MODEL FOR PROTECTING PRIVACY

open access: yesInternational Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2002
Consider a data holder, such as a hospital or a bank, that has a privately held collection of person-specific, field structured data. Suppose the data holder wants to share a version of the data with researchers. How can a data holder release a version of its private data with scientific guarantees that the individuals who are the subjects of the data

Extended k-anonymity models against sensitive attribute disclosure

open access: yesComputer Communications, 2011
p-Sensitive k-anonymity model has been recently defined as a sophistication of k-anonymity. This new property requires that there be at least p distinct values for each sensitive attribute within the records sharing a set of quasi-identifier attributes ...

Thoughts on k-Anonymization

22nd International Conference on Data Engineering Workshops (ICDEW'06), 2006
k-Anonymity is a method for providing privacy protection by ensuring that data cannot be traced to an individual. In a k-anonymous dataset, any identifying information occurs in at least k tuples. To achieve optimal and practical k-anonymity, recently, many different kinds of algorithms with various assumptions and restrictions have been proposed with ...

k-Anonymization Revisited

2008 IEEE 24th International Conference on Data Engineering, 2008
In this paper we introduce new notions of k-type anonymizations. Those notions achieve similar privacy goals as those aimed by Sweenie and Samarati when proposing the concept of k-anonymization: an adversary who knows the public data of an individual cannot link that individual to less than k records in the anonymized table. Every anonymized table that

MULTIPLE RELEASES OF k-ANONYMOUS DATA SETS AND k-ANONYMOUS RELATIONAL DATABASES

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2012
In data privacy, the evaluation of the disclosure risk has to take into account the fact that several releases of the same or similar information about a population are common. In this paper we discuss this issue within the scope of k-anonymity. We also show how this issue is related to the publication of privacy protected databases that consist of ...
