Privacy-preserving matching of spatial datasets with protection against background knowledge
GIS '10: Proceedings of the 18th SIGSPATIAL International Conference on Advances in Geographic Information SystemsPages 3–12https://doi.org/10.1145/1869790.1869795Private matching (or join) of spatial datasets is crucial for applications where distinct parties wish to share information about nearby geo-tagged data items. To protect each party's data, only joining pairs of points should be revealed, and no ...
