Abstract
A risk evaluation method and a risk evaluation device for evaluating an anonymous dataset generated according to an original dataset are provided. The risk evaluation method comprises the following steps. Acquiring a plurality of appearing times respectively corresponding to a plurality of original values of the original dataset. Generating a partition set and a weight table according to a sample parameter, an anonymous parameter and the appearing times. Dividing the original dataset into a plurality of data partitions according to the partition set, and generating a penetration dataset according to the weight table and the data partitions, wherein the penetration dataset comprises a plurality of sample data. Comparing each sample data with a plurality of anonymous data of the anonymous dataset to obtain a plurality of matching quantities respectively corresponding to the sample data. And calculating and outputting a risk evaluation result according to the matching quantities.
