UK transparency & privacy review

The independent review of the impact of UK government transparency on privacy, commissioned by the Cabinet Office and led by Dr Kieron O'Hara, is now out:

Comments are invited, to privacyreview@cabinet-office.gsi.gov.uk. No deadline date seems to have been given. (The public consultation on open data, launched in August,  is still open - deadline 27 Oct 2011.)

Conclusions

  • Privacy is extremely important to transparency. The political legitimacy of a transparency programme will depend crucially on its ability to retain public confidence. Privacy protection should therefore be embedded in any transparency programme, rather than bolted on as an afterthought.
  • Privacy and transparency are compatible, as long as the former is carefully protected and considered at every stage.
  • Under the current transparency regime, in which public data is specifically understood not to include personal data, most data releases will not raise privacy concerns. However, some will, especially as we move toward a more demand-driven scheme.
  • Discussion about deanonymisation has been driven largely by legal considerations, with a consequent neglect of the input of the technical community.
  • There are no complete legal or technical fixes to the deanonymisation problem. We should continue to anonymise sensitive data, being initially cautious about releasing such data under the Open Government Licence while we continue to take steps to manage and research the risks of deanonymisation. Further investigation to determine the level of risk would be very welcome.
  • There should be a focus on procedures to output an auditable debate trail. Transparency about transparency – metatransparency – is essential for preserving trust and confidence.

Recommendations

"…which are intended to implement these conclusions without making too strong a claim on resources":
1. Represent privacy interests on the Transparency Board.
2. Use disclosure, query and access controls selectively.
3. Include the technical paradigm.
4. Move toward a demand-driven regime.
5. Create a data asset register.
6. Create sector transparency panels.
7. A procedure for pre-release screening of data to ensure respect for privacy.
8. Extend the research base and maintain an accurate threat model.
9. Create a guidance product to disseminate best practice and current research in transparency.
10. Keep the efficacy of control in the new paradigm under review.
11. Maintain existing procedures for identifying harms and remedies.
12. Use data.gov.uk to raise awareness of data protection responsibilities.
13. Investigate the Vulnerability of Anonymised Databases.
14. Be transparent about the use of anonymisation techniques.

Lots of good analysis and especially the headline of avoiding making citizens transparant is crucial to a sustainable sosciety able to uphold a liberal market-based democracy.

One critical warning - a large part of the report is based on the thinking of anonymising a database. This is a fundamental mistake that will drive enourmous failures in design.

It drives a bureaucrat and gatekeeper thinking of First un-empowerment and MY control, then anonymisation for pseudo-transparancy.

This does not make sense in the cloud world where no server is secure. This does not make sense in a wireless world where all datapackets and device communcation is communicated into the open.

The consequences of this is accumulating destabilisation as power concentrates and security evaporates.

This not only goes for "privacy" of individuals but also for corporate competitivenes where companies experience their customers databases getting profiled by the ever-more invasive infrastructure and their customers being attacked for a multi-tude of reasons.

What we need to do is simple change to a paradigm where server-side equals online, i.e. identification needs to be isolated peer-to-peer or person-to-person. Each transaction should be purpose isolated as prevention and pushing controls client-side is the only effective security or economic strategy in the all-digital world

The sustainable means for reaching the same objective is moving entirely away from focus on identification towards security VERIFICATION, e.g. discussed here in the context of the need to utilise the flexibility of cloud without accepting security deteriorating into mere Security by Obscurity.
