Ensuring healthcare system integrity with blockchainBlockchain, the underlying protocol behind Bitcoin, has received a tremendous amount of attention over the last two years. Whilst initially focused on financial services, the technology holds much promise for addressing challenges in health-care system. Electronic health records and related information systems have several advantages over historical paper-based management - smooth data transfer between medical care providers, patient empowerment etc. While being convenient and efficient these systems always raise security concerns - how to ensure that such sensitive data is securely stored and how to protect against unauthorised access and manipulation.
And ultimately: who can we trust and on what basis? Blockchain technology has huge potential to solve the security issue - and today this is beyond theory - there are blockchain-based security solutions in production.
Guardtime's KSIGuardtime has developed Keyless Signature Infrastructure (KSI) - a blockchain technology for ensuring integrity of data, systems and processes. It provides data signatures that allow to assert integrity, signing time and signing entity of valuable assets - without trusting any central authority. It scales to billions of signatures per second - making it effectively possible to sign and verify every single medical record, access log entry etc.
Estonian Government has been one of the early adopters of the technology and there are integrations in production for several years already. One of the most recent integration is with Estonian E-health Foundation - for securing medical records against tampering and providing means to independently audit.
We look forward to meeting you on Wednesday, 21 September 2016. 14.30 - 17.15. Room Lima.
