Abstract
The system can be for the management of access authorization using an immutable ledger comprising and can include a server having a computer readable medium in communications with an immutable ledger. A set of computer readable instructions can be included in the server and can be configured for: receiving a set of data, encrypting the set of data with a data-encryption-key and storing the encrypted data on the immutable ledger, creating a key tree having a node associated with a user, creating a key-encryption-key associated with the node and the user, and, distributing the key-encryption-key to the user wherein the key-encryption-key is configured to decrypt the data-encryption-key thereby providing access to the data for the user.
