Google's DeepMind Plans To Use Blockchain For Tracking Medical Records


The tech company’s health subsidiary has plans to use blockchain as a way to track personal medical data in the UK with access provided to hospitals, the NHS, and patients themselves.

The Guardian reported that Google’s AI-powered DeepMind Health is revolutionizing the way medical records are stored and tracked, while also providing medical professionals with access to personal patient data in real time – through blockchain technology. 

DeepMind is using “Verifiable Data Audit” to help clinicians predict, diagnose, and prevent disease by serving as a data processor for hospitals, meaning that their role will be to provide secure data services while leaving hospitals in full control.

Medical data received by DeepMind’s system will be logged on a digital ledger that shares many (but not all) properties with a blockchain. Verifiable Data Audit will add entries to the ledger as patient procedures are administered, along with the reasons why. For example, data from a patient’s blood test can be checked against the NHS’s (National Health Service, UK) national algorithm to detect possible acute kidney injury.

Similar to a blockchain, the ledger will only append; enabling data to be added but not erased, creating an immutable record that third parties can use to verify the validity of entries, ensuring that the patient data has not been tampered with.
