Abstract :
Data Mining is a process of discovering useful
information in large data repositories. Data mining
techniques have been used to enhance information retrieval
systems. Privacy-preserving data mining (PPDM) refers to
the area of data mining that is primarily concerned with
protecting against disclosure of individual data records i.e.,
to safeguard sensitive information. To address about
privacy researchers in data mining community have
proposed various solutions. In this paper we present an
extensive review of all privacy preserving data mining
(PPDM) techniques. We use a classification scheme, which
is adopted from earlier studies, to review the techniques.
