Secure transmission of electronic health records via blockchain

A system for securely transmitting electronic healthcare records between a plurality of computing devices in communication with each other, comprising:

• one or more processors;
• and
• a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:
• receive, at a first computing device, a request from a second computing device to access at least one electronic health record in a database of electronic health records, wherein the request from the second computing device is based on accessing de-identified data of the at least one electronic health record, wherein the database of electronic health records is stored at a remote memory module, wherein the database of electronic health records comprises de-identified data accessible by the plurality of computing devices;
• send, from the first computing device, at least one authorization requirement to the second computing device;
• detect, at the first computing device, that the at least one authorization requirement has been provided by the second computing device;
• based on detecting that the at least one authorization requirement has been provided, generate, at the first computing device, a token associated with the at least one authorization requirement and the received request, wherein the token provides a decryption key for the encrypted identifiable data,
• wherein the token corresponds to a block in a Blockchain, the block including a cryptographic hash of a previous block, a timestamp, and transaction data related to the received request and the at least one authorization requirement;
• retrieve, by the first computing device, identifiable data from the remote memory module, wherein the identifiable data corresponds to the received request;
• encrypt, by the first computing device, the identifiable data;
• send the token to the second computing device from the first computing device to access the at least one electronic health record;
• and
• send, from the first computing device, the encrypted identifiable data to the second computing device.
