Conference Poster: 'Population grids protected by the Cell Key Method'
On 16th and 17th of April I visited the AnoSiDat conference ( Anonymisierung für eine sichere Datennutzung ). I had the opportunity to present preliminary results from my work done on 'Population grids protected by the Cell Key Method' in the poster session. The poster as well as corresponding R code to replicate its findings can be downloaded from my GitHub page . Quoting the abstract: "Population data for Census 2022 geographic grids (1ha) in Germany and several other nations will be protected by the Cell Key Method, a post-tabular perturbation technique. Is the fitness for purpose of the perturbed raster preserved? To address the question I run three archetypal spatial analysis tasks on a confidential (unprotected) raster and its perturbed counterparts (two variants) and compare the results." Highlights Illustrating an application of the ptable R package to create noise distributions for additive noise-based disclosure protection. Comparing population counts for...
