On the Representation and Querying of Sets of Possible Worlds in the K-anonymity Privacy Protecting Model
JieYuan Li, Guohua Liu · 2011
We represent a set of possible worlds using a k-anonymity privacy protection model. We introduce kpro-anonymity model, a space-efficient and complete representation system for finite sets of worlds. We study the problem of efficiently evaluating queries on sets of possible worlds represented by kpro-anonymity model.
