Alphabet's artificial intelligence (AI) division DeepMind continues to enhance its healthcare credentials with the arrival of a Bitcoin-like auditing process to protect the personal data of patients. The London-based firm is calling its data verification process the "Verifiable Data Audit". The idea is that it will give patients peace of mind with a "mathematical assurance about what is happening with each individual piece of personal data." It comes amid growing awareness of the value of personal data, and a loss in trust in organisation's abilities to protect their information. The NHS for example is notorious over its shoddy handling of patient data, with numerous incidents reported over the past few years.
