According to TechCrunch, a group of privacy researchers argues they have gathered the first evidence that a long-theorised vulnerability in systems anonymising data by aggregating noise, is 'no longer just a theory'. These findings add up the growing body of research suggesting that the risk of de-anonymisation on large datasets is persistent. This work was presented at the last USENIX Security Symposium by a team of researchers from Imperial College London and Universit¨¦ Catholique de Louvain.
