The UN is testing technology that processes data confidentially

How to analyse data without revealing their secrets

It’s in here somewhere!

DATA ARE valuable. But not all of them are as valuable as they could be. Reasons of confidentiality mean that many medical, financial, educational and other personal records, from the analysis of which much public good could be derived, are in practice unavailable. A lot of commercial data are similarly sequestered. For example, firms have more granular and timely information on the economy than governments can obtain from surveys. But such intelligence would be useful to rivals. If companies could be certain it would remain secret, they might be more willing to make it available to officialdom.

A range of novel data-processing techniques might make such sharing possible. These so-called privacy-enhancing technologies (PETs) are still in the early stages of development. But they are about to get a boost from a project launched by the United Nations’ statistics division. The UN PETs Lab, which opened for business officially on January 25th, enables national statistics offices, academic researchers and companies to collaborate to carry out projects which will test various PETs, permitting technical and administrative hiccups to be identified and overcome.
