Continued advancement in technology and the resulting digitalization in society has generated large electronic databases which are unstructured. The databases contain valuable hidden information which could be extracted through data mining to support organizations in strategic management. But these data sets consist of private and sensitive data about individuals and organizations which could be exposed in the data mining process thereby breaching the right to privacy of the owners. Even so, the valuable information hidden in the data need to be extracted to support organizations make strategic decisions. A range of privacy preservation techniques have been developed which could be used to protect private and sensitive data in a data mining process so that the right to privacy is not breached. This paper sought to discuss the privacy preservation techniques in data mining and their areas of application.
