Nathan C. Burnett has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11687564
    Abstract: A system performs masking of data stored in a database. The system receives change logs from a source database and masks the change logs to generate masked change logs. The system stores the masked change logs in a pre-buffer. If the system determines that the set of masked change logs stored in the pre-buffer corresponds to a complete transaction, the system determines whether any conflicts exist between masked change logs stored in the pre-buffer and masked change logs stored in a main buffer. If the system identifies conflicts, the system applies the masked change logs stored in the main buffer to a masked replica database. This causes the system to move masked change logs corresponding to a complete transaction from the pre-buffer to the main buffer.

  • Patent number: 11157651
    Abstract: A data processing system maintaining a plurality of masking engines is configured to synchronize masking jobs between different masking engines, in order to ensure consistent outputs between the different engines for the same job. Upon identifying a masking job object maintained by a first masking engine to be exported, dependencies of the job object are traversed to identify all objects depended on by the job object, which are used to form an export payload. At least object of the payload is a reference object that references other objects maintained by the first masking engine. When importing the export payload onto a second masking engine, the export payload is analyzed to identify revision information of the referenced object. The identified revision information is compared with revision information of a corresponding object maintained by the second masking engine, and the referenced objects is imported based upon a result of the comparison.
