Disaggregation of Digital Information and Data Sovereignty Compliance

Iris Anastasiadou, Dr Julinda Beqiraj, Dr Jean-Pierre Gauci

The huge amount of data stored outside of national boundaries has become a critical issue that is closely related to the question of data sovereignty (i.e., government control over domestic data), where rules introduced by states may result in both protection and limitations for companies that wish to resort to cloud services.

New research led by BIICL/Bingham Centre for the Rule of Law, with a focus on the UK, EU, US and Australia, finds that data sovereignty rules are upheld if digital information is disaggregated and disbursed across multiple geographic jurisdictions, where each storage service provider only has access to and processes a random fraction of binary digits related to the original information, otherwise unintelligible on its own. Moreover, relying on diversification of storage services seems a secure and resilient approach that reduces security risks - any damage, loss, or unwarranted access of data stored with a specific storage provider would only affect a random set of binary digits - while also possibly ensuring continued availability of data in the event of loss of functionality, end of business of the storage platform or data corruption.
