Abstract

Data anonymization techniques aim to protect the privacy of individuals while allowing data mining techniques to study valuable datasets. Up until recently, these techniques focused on one-time releases of large monolithic databases, but recently attention has been increasingly given to the problem of releasing anonymized versions of dynamic or correlated data.

In this dissertation, we categorize, critically survey and compare different approaches to this problem, which were published in this newly arising and important data anonymization area. We propose a new algorithm that aims to deal with this problem and compare it to the currently most accepted model in terms of quality of data and of processing time as well.
