Abstract
An anonymous dataset generation method comprises following steps. A critical attribute set and a quasi-identifier (QID) set are acquired, and one of the critical attribute and the quasi-identifier is set as an anchor attribute. An attribute sequence and an equivalence table are generated according to the quasi-identifier set and the critical attribute set. A data cluster and a cluster table are generated according to the equivalence table. The content of the cluster table is generalized to generate and output an anonymous dataset corresponding to an original dataset. A risk evaluation method for an anonymous dataset calculates data weight to extract distinctive data and to attacking defects of the anonymous dataset according to the distinctive data, thereby enhancing a risk evaluation efficiency of the anonymous dataset.
