Claim 6:
7. A method for securely managing access to a key using distributed ledger technology, comprising:
receiving a request to create at least one encrypted token, wherein the at least one encrypted token comprises at least one encrypted data attribute, at least one encrypted token salt, and at least one encrypted object ID encryption key;
generating a decryption key associated with the at least one encrypted token, wherein the decryption key is configured to decrypt the at least one encrypted token salt and the at least one encrypted object ID encryption key;
generating a smart contract that governs access to the decryption key;
storing the decryption key and the smart contract governing access to the decryption key on a permissioned blockchain;
requesting the decryption key associated with the at least one encrypted token;
based on the smart contract, receiving the at least one decryption key;
applying the at least one decryption key to the at least one encrypted token;
receiving at least one decrypted token; and
processing the at least one decrypted token, wherein processing the at least one decrypted token comprises comparing trusted source data to the at least one decrypted token to identify one or more missing data attributes.
