The QaR method to measure the extreme risk of re-identification of a database in the context of assessing its insurability

Scope

The methods described in this document apply to any dataset that can be represented as a table as described in Annex A, each record of which represents one statistical unit. The variables can be of any kind.
For insurance purposes, we may want a set of QaR calculations involving distinct databases to be published by a (sovereign or international) supervisory authority, which could then produce global statistics on the danger of a dataset, based on this QaR sample.
