Privacy-Preserving Database Systems

چکیده
Privacy is today an important concern for both users and enterprises. Therefore, intense research is today being carried out on various aspects of privacy-preserving data management systems. In this paper, we focus on database management systems (DBMS) able to enforce privacy promises encoded in privacy languages such as P3P. In particular, in the paper, we first present an overview of the P3P language and outlines some of its critical aspects. We then outline the main requirements for a privacy-preserving DBMS and we discuss solutions related to the management of privacy-related meta-data, focusing on special category of meta-data information, that is, purpose information. Purpose information represents an important component of privacy statements and thus their effective management is crucial. We then discuss current solutions to to fine-grained access control in the context of relational database systems and identify relevant issues.

The related anonymity level of a graph is formulated and a mathematical model is...
متن کاملPrivacy-Preserving Query Answering in Logic-based Information Systems
We study privacy guarantees for the owner of an information system who wants to share some of the information in the system with clients while keeping some other information secret. The privacy guarantees ensure that publishing the new information will not compromise the secret one. We present a framework for describing privacy guarantees that generalises existing probabilistic frameworks in re...
متن کاملPrivacy Preserving Data Mining
There is a tremendous increase in the research of data mining. Data mining is the process of extraction of data from large database. Knowledge Discovery in database (KDD) is another name of data mining. Privacy protection has become a necessary requirement in many data mining applications due to emerging privacy legislation and regulations. One of the most important topics in research community...
متن کاملPrivacy preserving association rules mining on distributed homogenous databases
Privacy is one of the most important properties that an information system must satisfy. In these systems, there is a need to share information among different, not trusted entities, and the protection of sensible information has a relevant role. A relatively new trend shows that classical access control techniques are not sufficient to guarantee privacy preserving when data mining techniques a...
