Fax Security Program

The TV show "Computer Chronicles" Saturday featured various comm security products, one of which used a fax encoding system with unusual capabilities to transmit color images, condensed text (say, a 30-page doc encoded on a single fax page) or any other digital data as visual clutter. The hard copy is scanned at the receiving end and the program decodes and decompresses to the original format. A demonstation showed that the clutter-code has error-correction robust enough to overcome any physical damage or defect in the transmittal or output. We missed the name of the product and would appreciate hearing from anyone who did, or who knows of the product.
