PRIVACY PRESERVING DATA PUBLISHING

Abstract

Privacy is an important issue when one wants to make use of data

that involves individuals sensitive information. Research on protecting

the privacy of individuals and the confidentiality of data has received

contributions from many fields, including computer science, statistics,

economics, and social science. In this paper, we survey research work in

privacy-preserving data publishing. This is an area that attempts to

answer the problem of how an organization, such as a hospital,

government agency, or insurance company, can release data to the

public without violating the confidentiality of personal information.

Focus is on privacy criteria that provide formal safety guarantees,

present algorithms that sanitize data to make it safe for release while

preserving useful information, and discuss ways of analyzing the

sanitized data.Many challenges still remain. Data in its original form,

however, typically contains sensitive information about individuals,and

publishing such data will violate individual privacy.Privacy-preserving

data publishing (PPDP) provides methods and tools for publishing useful

information while preserving data privacy.
