Abstract: Non-interactive data releasing has been a hotspot in differential privacy preservation model.A synthesis dataset releasing algorithm based on navie bayes was proposed.This algorithm computes the joint distribution of the original dataset based on the hypothesis of conditional independences in navie bayes firstly,then employs exponential mechanism to generate the synthesis dataset.The experiment results show that the accuracy of classifiers trained by the synthesis dataset improves and tends to be stable with privacy budget increasing.
