2016-11-26 · Big data is a term used for very large data sets that have more varied and complex structure. These characteristics usually correlate with additional difficulties in storing, analyzing and applying further procedures or extracting results. Big data analytics is the term used to describe the process of researching massive amounts of complex data in order to reveal hidden patterns or identify Geolocation with respect to personal privacy for the 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.

In recent years, a new definition of privacy called k-anonymity has gained popularity. In a k-anonymized dataset, each record is indistinguishable from at least k-1 other records with respect to certain "identifying" attributes. In this paper we show using two simple attacks that a k-anonymized dataset has some subtle, but severe privacy problems. Privacy in Data Mining - Computer Science & E 2019-4-4 · A.

2010-1-24 · Problem Space • Pre-existing privacy measures k-anonymity and l-diversity have flaws. • k-anonymity-each equivalence class has at least k records to protect against identity disclosure. • k-anonymity is vulnerable to homogeneity attacks and background knowledge attacks. • l-diversity: distribution of a sensitive attribute in each equivalence class has at

The work presented in this paper is highly inspired by [15]. L-Diversity: Privacy Beyond k-Anonymity
