Keeping Your Records Secure – Why Blockchain Matters
Blockchain technology is a key feature of Aria to make your records are secure and private, but we don’t want you to just take our word for it, so here are the reasons you can feel confident your medical records are protected:
All companies need to store some information, including personal information about you like your bank balance or your Amazon shopping preferences. The problem is that this means one company controls all this information, can use the data as they want and there is a risk that someone (like an employee or a hacker) could accidentally or maliciously leak or edit your data.
With a blockchain, and in Aria, there is a group of trusted parties who make sure your data is protected. No one party can access the data or edit it without the permission of the others. In fact, every change made to the blockchain, such as a new medical record being added, needs to be approved by everyone, and every addition or change is recorded.
So, while we hope you do trust us, you don’t need to!
- You Hold the (Private) Key
When your records are retrieved from your medical centre, they are stored in the blockchain. However, instead of storing them as they are, we store them in an encrypted format i.e. they are converted into a long string of numbers and letters. So even if someone managed to get your records from our blockchain database, they wouldn’t be able to read them, they would just see a load of nonsense.
To decode these records, there is a unique private key. Only you are provided with the private key which decodes any records relating to you. Ensuring your records are completely private to you and whoever you wish to share them with.
To learn more about encryption, see our article “Keeping Your Records Secure – Encrypting Your Medical Records”.
Now we think that makes your records pretty secure!
If you want to know more about how a Blockchain works, this is one of our favourite simple explanation videos (it’s just 6 minutes)
To make things even more secure, when new information is put onto the blockchain database, it is put in a ‘block’. This means, for example, every ten minutes the system gathers all the information which has been requested to be put in the database, and groups it into one block. Once all the parties agree that this information is safe to be added, then it is timestamped and ‘locked’. As a result, no one can go back and edit this data, once it is approved it is immutably recorded in the blockchain, meaning the data can never be deleted or edited.
This is especially important in medical records, as your doctor, researcher or insurer, needs to know that the data they are being provided with is complete and the original, correct data.
