Secure QR code system for distributed large payload transmissions for everyday use

Abstract

A system for transferring a data file includes a first data device (124) that is configured to: partition the data file (200) into a plurality of sub-units (202); generate a plurality of sequence bits (211) for each sub-unit that indicates a place in the data file (200) that the sub-unit belongs; for each sub-unit, integrate the sequence bits into the sub-unit; and convert each sub-unit into a different sub-unit QR code (221), thereby generating a plurality of sub-unit QR codes (221, 222 . . . 229); and transmit each of the sub-unit QR codes (221, 222 . . . 229). A second data device (130) is configured to: receive each of the sub-unit QR codes (221, 222 . . . 229); convert each of the sub-unit QR codes (221, 222 . . . 229) into corresponding reconstructed sub-units; and assemble the reconstructed sub-units nto a reconstructed data file (110′) in an order indicated by the sequence bits.
