The challenge of anonymisation in the era of big data

The challenge of anonymisation in the era of big data - 2018.
11
The National Health Data System (SNDS — Système national des données de santé) raises the issue of open health data and has revived discussions on the anonymisation of personal data. The attributes of anonymous data are a serious question, insofar as they constitute either a legal obligation (open data) or a tool for compliance with the protection of personal data.However, in the era of Big Data and progress in data analysis, there is still a risk of re-identification. Faced with a strict interpretation of anonymisation on the part of the G29, which has adopted a “zero risk” approach, anonymisation needs to be rethought. While the CNIL ( Commission nationale de l’informatique et des libertés) has recently been given the task of publishing benchmarks for the certification of anonymisation procedures, the article presents the limits of this approach which is too strict and mainly based on technical criteria. It advocates a more flexible interpretation of anonymisation through the establishment of pre-defined risk thresholds according to the context, allowing anonymity to be assessed and strengthening legal measures.
