Secure document transmission

Embodiments of the invention relate to a method and a system for safely transmitting a document from a first network to a second network, while obviating the risk of transferring malware contained within the document to the second network. Embodiments of the invention involve separating binary data elements from text based data elements in a document, preferably a document in digital form. The binary data is then converted into analog media using an analog convertor, and then received by an analog receiver associated with the second network. Text-based data elements may remain in digital form, be cleaned of scripts, and are transferred to the second network in digital form. The document may be reconstructed using a computing device of the second network by combining data received via the analog receiver and the digital data comprising text-based data.
