Abstract
Methods and apparatus are disclosed to anonymize a dataset of spatial data. An example method includes generating a spatial indexing structure with spatial data, establishing a height value associated with the spatial indexing structure to generate a plurality of tree nodes, each of the plurality of tree nodes associated with spatial data counts, calculating a localized noise budget value for respective ones of the tree nodes based on the height value and an overall noise budget, and anonymizing the plurality of tree nodes with a anonymization process, the anonymization process using the localized noise budget value for respective ones of the tree nodes.
