% \kat{mention also the different ways data are organized, e.g., as tuples in tables, KVs, graphs, etc and in what formats you consider them in this work.}
|
|
In this chapter, we introduce some relevant terminology and information around the problem of
|
|
quality and privacy in user-generated Big Data with a special focus on continuous data publishing.
|
|
% continuous publishing of privacy-sensitive data sets
|
|
% \kat{the title of the thesis is '..in user generated big data' not in 'continuous publishing'. Consider rephrase here, and if needed position the user generated big data w.r.t. the continuous publishing so that you continue later on discussing for the continuous publishing setting. }
|
|
First, in Section~\ref{sec:data}, we categorize user-generated data sets, that we consider in a tabular form, and review data processing in the context of continuous data publishing.
|
|
Second, in Section~\ref{sec:privacy}, we define information disclosure in data privacy. Thereafter, we list the categories of privacy attacks, %identified in the literature,
|
|
the possible privacy protection levels, the fundamental privacy operations that are applied to achieve data privacy, and finally we provide a brief overview of the
|
|
% \kat{also here reconsider the term seminal, so as it does not read like we are in the related work section}
|
|
% seminal works on privacy-preserving data publishing.
|
|
basic notions for data privacy protection.
|
|
% \kat{The correlations are not intuitively connected to privacy, so put here a linking sentence to data privacy.}
|
|
Third, in Section~\ref{sec:correlation}, we focus on the impact of correlation on data privacy.
|
|
More particularly, we discuss the different types of correlation, we document ways to extract data correlation from continuous data, and we investigate the privacy risks that data correlation entails with special focus on the privacy loss under temporal correlation.
