MAINTAINING SECURITY OF A DOCUMENT COMMUNICATED BY FAX

摘要

PURPOSE: A method to maintain security of a document communicated with a facsimile and a computer-readable medium are provided to maintain security of the document by encoding the document transmitted through the facsimile to 2D bar code. CONSTITUTION: An original document to be transmitted through a facsimile is generated to an image file encoded to 2D(Dimensional) bar code(530). The image file is transmitted through the facsimile(540). The 2D bar code includes the first 2D bar code encoding a content of the original document and the second 2D bar code encoding information related to the original document except for the content of the original document. The second 2D bar code has stronger force of restitution than the first 2D bar code.
