Differentially private grids for geospatial data [PDF]
2013 IEEE 29th International Conference on Data Engineering (ICDE), 2013 In this paper, we tackle the problem of constructing a differentially private synopsis for two-dimensional datasets such as geospatial datasets. The current state-of-the-art methods work by performing recursive binary partitioning of the data domains, and constructing a hierarchy of partitions. We show that the key challenge in partition-based synopsis
