Data Restoration and Privacy Preserving of Data Using C4.5 Algorithm
Data mining extracts knowledge to support a variety of areas as marketing, medical diagnosis, weather forecasting, national security etc. successfully. There is an improved advance in hardware technology which increases the capability to store and record personal data about consumers and individuals. So there is a challenge to extract certain kinds of data without violating the data owners' privacy. As data mining becomes more enveloping, such privacy or security concerns are increasing. This gives birth to a new branch of data mining method called Privacy Preserving Data Mining algorithm (PPDM).
