A STUDY ON PRIVACY PRESERVING BIG DATA MINING: TECHNIQUES AND CHALLENGES

Abstract

The basic goal of data mining algorithms is to extract previously undiscovered patterns from the data. When mining the data, sensitive and confidential information should be secured simultaneously to protect privacy. Due to the widespread use of information technology, enormous amounts of data are being produced at an exponential rate by several organisations, including hospitals, insurance providers, banks,e-commerce, and stock exchanges, making privacy a crucial concern in data mining. Anonymization, Perturbation, Generalization, and Cryptography are some of the privacy-preserving data mining techniques that have been proposed in the literature. In this study, we have reviewed all of these state of art techniques and presented a tabular comparison of work done by different authors as well as discussed the challenges of privacy preserving data mining.
