Literature Review on Secure Mining of Association Rules in Horizontally Distributed Databases

Data and knowledge Engineering is one of the area under data mining. Which can extract important knowledge from large database, but sometimes these database are divided among various parties. This paper addresses a fast distributed mining of association rules over horizontally distributed data. This paper presents different methods for secure mining of association rules in horizontally distributed databases. The main aim of this paper is protocol for secure mining of association rules in horizontally distributed databases. The current main protocol is that of Kantarcioglu and Clifton. This protocol, like theirs, is based on the Fast Distributed Mining (FDM) algorithm of Cheung et al., which is an unsecured distributed version of the Apriori algorithm. The main components in this protocol are two novel secure multi-party algorithms — one that computes the union of private subsets that each of the interacting players hold, and another that tests the inclusion of an element held by one player in a subset held by another. This protocol offers improved privacy with respect to the protocol in. In addition, it is simpler and is significantly more efficient in terms of communication rounds, communication cost and computational cost
