In today's world, there is an improved advance in hardware technology which increases the capability to store and record personal data about consumers and individuals. Data mining extracts knowledge to support a variety of areas as marketing, medical diagnosis, weather forecasting, national security etc. successfully. Still there is a challenge to extract certain kinds of data without violating the data owners' privacy. As data mining becomes more enveloping, such privacy concerns are increasing. This gives birth to a new category of data mining method called Privacy Preserving Data Mining algorithm (PPDM).
