The authors propose transaction databases where the user requirements changes accordingly. The association is for predict the user needs with the given data. Before, there were some algorithms which are fast and not secure one, another set of algorithm which has a security based protocol but the processing time is high. So, they propose secure mining of item sets in a database that is dispersed horizontally. They propose two protocol for security purpose and the one protocol is current leading protocol is based on the Fast Distributed Mining (FDM) algorithm which provides fast retrieval of item sets from a database that is distributed horizontally.
