Abstract

An active distributed ledger may comprise an indication of an inactive permission associated with a user device. An entry comprising such indication added to another distributed ledger that is supplemental to the active distributed ledger. An updated active distributed ledger may be generated that does not comprise the indication of the inactive permission. The updated active distributed ledger may comprise an indication of a new permission associated with the user device. The updated active distributed ledger may be stored on the user device or any other device on a network.

Core Innovation

The invention provides blockchain folding for device permission management. A first distributed ledger record on a primary distributed ledger represents an active permission associated with a user device, and the first distributed ledger record includes an identifier that indicates a position of the first distributed ledger record on the primary distributed ledger.

When an updated active permission associated with the user device is received as a second distributed ledger record, the first distributed ledger record is removed from the primary distributed ledger. The removed first distributed ledger record is stored on a secondary distributed ledger located on a storage device as an inactive record, and the identifier indicating the position of the first distributed ledger record on the primary distributed ledger is preserved in the inactive record on the secondary distributed ledger.

The user device, computing device, and storage device are used to determine, receive, remove, and store distributed ledger records. The inactive record may correspond to permissions that are expired, revoked, or associated with a security compromise. The document further discusses using original and secondary block number references and hash recalculation when reconstructing or reconstituting an original ledger by merging active and secondary ledger branches.

Claims Coverage

The independent claims are directed to blockchain folding of distributed ledger records for active permission updates, including removal from a primary distributed ledger and storage of the removed record as an inactive record on a secondary distributed ledger while preserving a position identifier. Across the independent claims, the core inventive concept includes 3 main inventive features.

Across the independent claims, coverage centers on folding prior active permission records: a first active permission distributed ledger record on a primary distributed ledger is removed after an updated active permission record is received, and the removed record is stored as an inactive record on a secondary distributed ledger while preserving the identifier that indicates the position of the removed record on the primary distributed ledger.
