Although privacy preservation in data publishing has been studied extensively and several important models such as k-anonymity [35]andl-diversity [27] as well as many efficient algorithms have been proposed, most of the existing studies can deal with relational data only. Those methods cannot be applied to social network data straightforwardly.
A Framework for Privacy-Preserving Cluster Analysis Benjamin C. M. Fung Concordia University Canada fung@ciise.concordia.ca Lingyu Wang Mourad Debbabi Privacy Preservation of Data in Data mining using K The main aim of the privacy preservation is protecting the sensitive information in data while extracting knowledge from large amount of data. There are many techniques are use in privacy preservation like k-anonymity, l-diversity, t-closeness, blocking based method and cryptography techniques. K - anonymity: An Introduction | Privitar Apr 07, 2017 ACHIEVING k-ANONYMITY PRIVACY PROTECTION USING L. Sweeney. Achieving k-anonymity privacy protection using generalization and suppression. International Journal on Uncertainty, Fuzziness and Knowledge-based Systems,10 (5), 2002; 571-588.

However, unencrypted data provides no guarantee for anonymity. In order to preserve privacy, k-anonymity model has been proposed by Sweeney [5] which achieves k- anonymity using generalization and suppression [5], In K- anonymity, it is difficult for an imposter to decide the identity of the individuals in

In this paper, we address privacy issues related to ranked retrieval model in web databases, each of which takes private attributes as part of input in the ranking function. Many web databases keep private attributes invisible to public and believe that the adversary is unable to reveal the private attribute values from query results. However, prior research (Rahman et al. in Proc VLDB Endow 8 Apr 07, 2017 · This introduction looks at k-anonymity, a privacy model commonly applied to protect the data subjects’ privacy in data sharing scenarios, and the guarantees that k-anonymity can provide when used to anonymise data. In many privacy-preserving systems, the end goal is anonymity for the data subjects.

Jan 09, 2008 · The baseline k-anonymity model, which represents current practice, would work well for protecting against the prosecutor re-identification scenario. However, our empirical results show that the baseline k-anonymity model is very conservative in terms of re-identification risk under the journalist re-identification scenario.
