Journal ArticleDOI
Progressive skyline computation in database systems
TL;DR: In this paper, a branch-and-bound skyline (BBS) algorithm based on nearest-neighbor search is proposed, which is I/O optimal and performs a single access only to those nodes that may contain skyline points.
Proceedings ArticleDOI
An optimal and progressive algorithm for skyline queries
TL;DR: BBS is a progressive algorithm also based on nearest neighbor search, which is IO optimal, i.e., it performs a single access only to those R-tree nodes that may contain skyline points and its space overhead is significantly smaller than that of NN.
Proceedings ArticleDOI
Anatomy: simple and effective privacy preservation
Xiaokui Xiao,Yufei Tao +1 more
TL;DR: A linear-time algorithm is developed for computing anatomized tables that obey the l-diversity privacy requirement, and minimize the error of reconstructing the microdata.
Book ChapterDOI
Query processing in spatial network databases
TL;DR: A Euclidean restriction and a network expansion framework that take advantage of location and connectivity to efficiently prune the search space are developed and applied to the most popular spatial queries.
Proceedings ArticleDOI
Personalized privacy preservation
Xiaokui Xiao,Yufei Tao +1 more
TL;DR: Wang et al. as discussed by the authors presented a new generalization framework based on the concept of personalized anonymity, which performs the minimum generalization for satisfying everybody's requirements, and thus retains the largest amount of information from the microdata.
