Systems, methods, and computer medium to securely transfer large volumes of data between physically isolated networks having different levels of network protection

摘要

Embodiments of computer-implemented methods, systems, and non-transitory computer-readable medium having one or more computer programs stored therein are provided to transfer contents of transactional database records associated with a data historian between two or more networks configured to have different levels of network protection. Generated data barcodes can be decoded to produce contents of transactional database records to be transmitted between two or more networks having different levels of network security protection. Decoded contents of the transactional database records can then be securely communicated back to the sender for comparison by generating validation barcodes to be decoded by the sender. Generated verification barcodes can then be decoded to produce verification data. Verification data can confirm success of the transmission of contents of transactional database records encoded in the data barcodes. Decoded contents of transactional database records can then be stored responsive to an indication of successful transmission.
