We believe that doctors should have seamless access to accurate records, at the right time. But we also believe that patients should have access to their own information as well, so they can learn, collaborate and take care of their own health. The question around access comes down to who can see what information, and making sure those without authorisation to particular records aren't able to view them. There must be a secure way of organising such permissions and blockchain technology offers such an opportunity. The simultaneous features of security and interoperability allow us to build a product around instantaneous and seamless access.
With a decentralised network however, Lacuna can't use passwords in the same way we see used in centralised organisations. If patients lose them, we can't issue a new one. If we could, the security feature of blockchain wouldn't exist. Instead, it is here that we allow ones identity to unlock their data. Your identity is kept on the blockchain as well, so it can't be tampered with and is wholly owned by you. This identity management is a much more secure approach than traditional password systems. Identity partners to be announced soon.
Put simply "a patient can choose to grant access to any healthcare provider of his choice by using his [identity] along with that of the hospital. This way, the patients will have full access to their own data and they can choose the healthcare provider they would like to share it with. It will also save hospitals from the huge costs associated with setting up and maintaining patients’ electronic records."
