Privacy preservation in self-governing openness of data

Abstract

The openness of data is very important for improving the application value of data resource.However,due to the consideration of privacy preservation,data should be open under supervision.That is,data should be in the mode of selfgoverning openness.For challenges that self-governing openness of data may bring,a possible system framework for the privacy preservation of a data box was presented.The system framework carries out the privacy disclosure risk evaluation for the data usage declaration of a data user,and then determines whether the corresponding data usage request can be authorized or not on the basis of evaluation results,and thus supports the implementation of self-governing openness of data.
