Standardised Secure E-Mail Using Fax

A standardised way of sending secure images and digitised documents over IP connections, device-to-device across POTS systems, or in any combination.

You sell your FAXoIP software online from your https secure server. On a computer it can work like FAX software over POTS. It can also work over IP rather like a VoIP service.

You prepare a document (image, text, pdf) and you print it using the FAXoIP driver, just like FAX software. You pull the recipient from your address book. You can send it over POTS, VoIP, or IP. Say you choose IP.

Your software checks directly across the net (fixed IP) or via a secure server (dynamic IP, logging on when you go online) to see if the recipient has a secure key. If not, it tells them to expect one, and sends one securely via a secure server. Keys can be single-use, time-limited, or permanent. Then it sends the encrypted document using an enhanced fax standard, direct PC to PC over IP.

It can do the same with a compliant FAX machine containing a pre-programmed dial-up chipset for getting keys and TRXing faxes over IP.

Because it uses the fax standard, and is backwards compatible with fax, it is not an unusual, non-standard or novel product, and it doesn't interfere with your e-mail client.

Finally, a standardised IP-based secure mail protocol that works immediately, like messaging. If the destination PC is off, you can hold the document and retry later, or subscribe to space on a secure server and store it there-when the recipient logs on, it is sent.

There is already a colour fax standard (ITU-T30E) although an amended protocol can send data in any form to a suitably compliant fax machine (across POTS or IP) or to another computer. This is no technological leap forward, but a solution to the simple problem of there being numerous non-interoperable secure mail clients.
