Data Control Ledger for Secure Account Modification

The patent introduces a data control device as an intermediary between network devices and provisioning service devices. This mediator receives service requests from network devices, processes them, and communicates with provisioning service devices on behalf of the network devices. The data control device maintains a data control ledger to track all service requests and actions, preventing direct interactions that would compromise security while enabling efficient service processing through the intermediary layer.

The data control ledger serves multiple functions within the system: it tracks service requests, records actions performed on user accounts, maintains immutable audit logs, and provides the basis for error correction. By consolidating these functions into a single ledger structure managed by the data control device, the system achieves comprehensive auditability without proportionally increasing complexity, as the same ledger infrastructure supports all auditing and tracking needs.

The patent implements segmentation by creating separate data control ledgers for different groups within an enterprise. Each group has its own ledger that tracks user account information specific to that group, allowing data compartmentalization and targeted security control. The integrated data control ledger architecture connects these segmented ledgers, enabling end-to-end tracking while maintaining security boundaries. This segmentation approach allows different groups to manage their data independently while the integration layer provides overall coordination.
