Why it matters

Britain and France moved in opposite directions on the same problem Thursday: one disclosed a breach involving 500,000 research volunteers, the other dumped a foreign cloud provider for a domestic one. (bloomberg.com) (scaleway.com) In London, technology minister Ian Murray told the House of Commons on April 23 that UK Biobank data had appeared in three listings on Alibaba’s site, after the government was notified on Monday, April 20. UK Biobank said the dataset involved de-identified records from 500,000 participants. (gov.uk) (bloomberg.com) (digitalhealth.net) UK Biobank said the data had been made available to researchers at three academic institutions and then listed for sale in China in breach of contract. It said Alibaba removed the listings before any sales were made, and the institutions and individuals involved had their access suspended. (digitalhealth.net) (gov.uk) The breach hit one of Britain’s biggest medical research resources. UK Biobank was set up in November 2003 and built its database from 500,000 volunteers whose data has been used in studies on cancer, dementia, Parkinson’s disease and Covid-19. (ukbiobank.ac.uk) (gov.uk) UK Biobank’s immediate response was operational, not diplomatic. It temporarily suspended all access to its research platform, imposed stricter file-export limits, and said exported files would be monitored daily for suspicious activity. (digitalhealth.net) In Paris, France’s Health Data Hub said the same day that Scaleway had been chosen to replace Microsoft as future host of the platform. Scaleway said the system will host health databases including a copy of the main database of the National Health Data System. (scaleway.com) (thestar.com.my) France’s argument was about control before any new breach, not after one. Scaleway said it won after a selection process using more than 350 technical criteria, and said its infrastructure is operated in Europe with a roadmap toward France’s SecNumCloud standard for sensitive systems. (scaleway.com) That fight had been running for years. In October 2020, France’s top administrative court refused to suspend Microsoft hosting for the Health Data Hub, even as the national data protection authority, the Commission nationale de l'informatique et des libertés, had warned about risks after the Schrems II ruling on transatlantic data transfers. (hoganlovells.com) (hunton.com) The two cases turn on the same design question: where sensitive data lives, who can move it, and what rules apply when something goes wrong. Britain is now tightening how researchers can take data out; France is tightening who gets to host it in the first place. (digitalhealth.net) (scaleway.com)
