ROTATION BASED TRANSFORMATION METHOD AND APPARATUS FOR PRESERVING DATA PRIVACY, PARTICULARLY FOR PROTECTING THE PRIVACY OF DATA TO REDUCE THE INFLUENCE OF AN AK-ICA

摘要

PURPOSE: Rotation based transformation method and apparatus for preserving data privacy are provided to relieve the attack of an AK-ICA(Aproiori Knowledge Independent Component Analysis) for an RBT used in a privacy protection data clustering.;CONSTITUTION: A data division unit(12) divides a given data set into plural sub-sets having the same size, and a rotation conversion unit(13) performs the rotation conversion of the plural data sub-sets by using corresponding rotary matrixes. A jointing unit(14) joints the rotated data sub-sets to create the rotated data sets. A data release unit(15) releases the rotated data sets to use the rotated data sets in data mining.;COPYRIGHT KIPO 2010
