[MyData & Open Data] Study establishes that de-identification does work

Mon Jun 16 18:30:36 UTC 2014

Not quite. A report dealing with a particular selection of commonly-quoted examples of re-identification points out some facts; concedes that de-identification is complex, evolving and context-specific, has to be done properly by experts to be effective and may impact on the utility of the data so treated.

Dr Covoukian fails to address some of Sweeney’s more recent re-identification work, e.g. http://www.bloomberg.com/news/2013-06-05/states-hospital-data-for-sale-puts-privacy-in-jeopardy.html and ducks the reality that there’s an enormous amount of badly de-identified (or pseudonymised) data already out there- which itself may provide vectors for attack.

Study provides evidence that re-identification is a myth (http://www.privacybydesign.ca/index.php/paper/big-data-innovation-setting-record-straight-de-identification-work)
