Abstract:

The explosion of data poses increasingly challenges on privacy preservation.This paper introduces basic technologies related to the privacy preservation in data mining,and puts forward a mining algorithm under association rule to deal with the Boolean data set distributed in a centralized manner.The method compresses the data set while preserving privacy,thus enormously reducing the time of data mining.Test results show that the mining time is significantly reduced with acceptable errors by this algorithm.
