The Airmed Foundation is an open source initiative working under the AGPL-3.0 License. We provide a secure channel to store and transfer medical records. We do this through the Interplanetary File System (IPFS) and Hyperledger Fabric. The conjunction of these technologies guarantees the immutability and availability of the data. We replicate all records through the IPFS network, using the Bitttorrent protocol. We achieve secure access to files through asymmetric cryptography. We protect and store access keys in the Hyperledger Fabric blockchain.
How does it work?
There are two ways to use Airmed.
The first and easiest is to upload a file and share it publicly through the hash address that the system returns. This allows you to download it from any InterPlanetary Filesystem client that is connected to the public network. Files also become available through the IPFS gateway. Just attach the hash address to the IPFS url, as shown below.
With a file with IPFS hash being
https://gateway.ipfs.io/ipfs/<the hash address goes here>
The second and more private way is using asymmetric encryption. This stores keys in Hyperledger Fabric’s blockchain and allows restricting access to specific entities. For this process, we have created this tutorial.
