L-Diversity: Privacy Beyond K-Anonymity

2020-6-12 · Both k-anonymity and l-diversity have a number of limitations. These privacy definitions are neither necessary nor sufficient to prevent attribute disclosure, particularly if the distribution of sensitive attributes in an equivalence class do not match the distribution of sensitive attributes in the whole data set. t-closeness addresses this problem by requiring that the distribution of a An overview of methods for data anonymization 2015-3-27 · [LLV07] Li N, Li T, Venkatasubramanian S. t-Closeness: privacy beyond k-anonymity and l-diversity.

Background Collecting data on the localization of users is a key issue for the MASK (Mobile Airways Sentinel networK: the Allergy Diary) App. Data anonymization is a method of sanitization for privacy. The European Commission’s Article 29 Working Party stated that geolocation information is personal data. To assess geolocation using the MASK method and to compare two anonymization methods in

2011-3-22 · Several models such as p-sensitive k -anonymity [15], l-diversity [7], (α, k )-anonymity [19] and t-closeness [6] were proposed in the literature in order to deal with the problem of k anonymity. The work presented in this paper is highly inspired by [15].
