Pointer: Encrypted fax patent Publication: The New York Times, July 18,, 1994; Business Section D; Patents column; p. D2. Title: A small Company offers a scanning device to make faxes private by encoding their computer bits. By: Sabra Chartrand Some excerpts: The Kryptofax Corporation . . . was set up to sell a scanning device that uses encryption algorithms to turn fax text into indecipherable dots on a page. *** Then the most critical thing is to provide a password, says Richard Varga, a former computer programmer who is the president. *** The encoded page emerges with the title and addressee name appearing in plain language at the top. The rest is a grid of random dots. *** As the [receiving] Kryptofax machine reads the encrypted grid, it begins simultaneously to print a decrypted version of the page. *** We use an encryption algorithm called seeded pseudo-random number generator, Mr. Varga said. The company chose that algorithm because it is in the public domain, he added. *** The Kryptofax Corporations's patent is 5,321,749.
