Claim 15:
16. A computer-readable media storing non-transitory computer executable instructions that when executed cause a computing system to perform a method for securely managing a key in a DLT environment 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;
generating a smart contract, wherein the smart contract comprises at least one rule that governs access to the decryption key;
storing the smart contract, the decryption key on a permissioned blockchain;
receiving at least one request to access the decryption key;
determining whether to grant access to the decryption key based on the at least one rule governing access to the decryption key;
based on the determination, granting access to the decryption key;
applying the 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.
