Concept of data preservation has become a challenging task. Security of the data is one of the prime concerns in today’s technology. Privacy Preserving Data Mining (PPDM) deals with the protection of private data. Association rule mining and frequent item-set rule mining are highly used for application purposes. These lead to approximations which have high accuracy, low data leak-age and improvement in efficiency. Transparency of the data processing should be limited to the users involved in order to minimize the leakage of sensitive business infor-mation. Accuracy and efficiency is being obtained from the rules. Homomorphic encryption scheme is been developed to ensure data privacy. The data is transformed by the owner in order to provide privacy which is then sent to the server. The server receives the mining queries which are then sent to the cloud to get the desired solution. SIN order to protect the sensitive information in the corporate field, the owner would perform ROBFRUGHAL encryption scheme which is transformed to the server.
