The decentralized and distributed architecture of blockchain makes it challenging to store secret data. A Secure Document Access Control System (SEDACS) can store secret data using distributed components without compromising on the distributed security features of the blockchain. SEDACS can include a Secret Store, a blockchain, and a decentralized file system. The blockchain can store rules and permissions for documents that contain the secret data. The Secret Store can generate secret keys that can be used to access the documents. The decentralized file system can store the documents that are encrypted using the secret keys. A user can retrieve the encrypted document provided that the user has the permission to do so. The user can decrypt the encrypted document by decrypting the secret key and using the decrypted secret key to decrypt the document. Link to Full Patent
