The boss of UK Biobank, Professor Sir Rory Collins, has indicated that the recent data breach involving the medical information of 500,000 participants was due to 'a few bad apples' responsible for the incident, which he described as deeply troubling.
Last week, it was reported that datasets containing de-identified information about volunteers were posted for sale on a Chinese website, Alibaba. The UK government confirmed these listings were quickly removed before any transactions occurred, but scrutiny over the Biobank's data management practices has intensified following the incident.
Professor Collins expressed anger and disappointment during an interview with the BBC, emphasizing that those institutions involved have been banned from accessing the Biobank's platform. He stated that the organization is currently 'putting science on hold' by suspending access to its online research platform as it evaluates and enhances its data security controls.
The UK Biobank collects extensive health data from volunteers and has been pivotal in advancing research in conditions such as dementia and certain cancers. It allows approved researchers worldwide to access its datasets, consisting of anonymized participant medical details.
In light of the breach, Collins highlighted the swift collaborative efforts between UK and Chinese governments that led to the removal of the compromised listings. However, he acknowledged the challenge in completely preventing misuse of data, as he noted, 'a few bad apples have taken those data off the platform.'
The technology minister, Ian Murray, reassured that the compromised data did not include names or contact details but could potentially expose information such as gender, age, and lifestyle habits. This has raised discussions regarding the risk of re-identification, although Collins stated that there is currently no evidence to indicate any participant has been identified through this breach.
The Biobank has reported the incident to the Information Commissioner's Office (ICO) for further investigation. Furthermore, a board-led inquiry into the incident has commenced to ensure robust data security measures moving forward.
Sir Rory concluded by emphasizing the importance of maintaining a balance between accessibility for scientific advancement and proper data protection protocols, stating, 'UK Biobank has allowed discoveries that otherwise would never have emerged about how to prevent and treat diseases like dementia.'
