Anonymisation does not work for big data

Recently, well-publicised research by data scientists at Imperial College in London and Université Catholique de Louvain in Belgium as well as a ruling by Judge Michal Agmon-Gonen of the Tel Aviv District Court have highlighted the shortcomings of outdated data protection techniques like “Anonymisation” in today’s big data world.

Anonymisation reflects an outdated approach to data protection developed when the processing of data was limited to isolated (siloed) applications prior to the popularity of “big data” processing that involves widespread sharing and combining of data.
