Research Abstract |
Throughout the project a partial progress has been estalished on the evaluation of the disclosure risk of perturbed or synthetic microdata. Especially it is important that an objective method has been proposed on the decision of the threshold value of microdata disclosure risk. It is so because the current practice of that decision is so subjective that anonymization techniques are not widely accepted. Another progress of this project has been seen in the evaluation of the marginal distribution of a random partitioning distribution. This result employs combinatorial arguments, which lead to an exact derivation of a measure of microdata disclosure risk.
