结合锚点优选算法改进的SpaceTwist隐私保护方法
Improved SpaceTwist privacy protection method based on anchor optimization algorithm
摘要
Abstract
With location-based services worldwide used, private location data appealed easily in query process which caused serious security problems. So the introduction of SpaceTwist incremental nearest neighbor query algo-rithm,proposes protection of privacy method combined with improved SpaceTwist location optimization algorithm. The anchor point authentication server added to distributed system structure, user generate a k anonymous area according to their privacy preference and actual environment, using optimization algorithm to generate the anchor point. Forwarding users use the incremental nearest neighbor query throught the anchor point and accurate. Experiments in road network environment with different data sets show that the privacy protection works well in the algorithm, and own high work ef-ficiency.关键词
