Sender: owner-cryptography@c2.net From: "Jongsma, Ken (NM75)" <ken.jongsma@das.honeywell.com> Date: 24 Oct 1997 10:32:24 -0600 Subject: Hiding In Plain Sight from the Oct 20 Aviation Week: "Researchers at Los ALimos National Laboratory have patented a new software technique that can hide secret information in the electronic "noise" associated with the transmission of data and electronic images. Called "data embedding," the method allows classified data to be stored and transferred in open transmissions and can serve as an "electronic watermark" to prevent unauthorized manipulation of digital images and other information, according to Ted Handel, project leader. The software can be used on a desktop personal computer and consumes only 512 kilobytes of memory, less than most word processing programs. It is written in "C" computer language which conforms to virtually any digital storage medium. Overall document length can remain the same." Aside from the obvious errors in the story, do you suppose that someone ought to clue the patent office in that steganography has existed for quite a while now? If anyone would like to research the patent and report back, it would be interesting to see what is so unique that the could get a patent on it. -- ken.jongsma@das.honeywell.com 505 828-5876 Voice 505 828-5500 Fax --- end forwarded text ----------------- Robert Hettinga (rah@shipwright.com), Philodox e$, 44 Farquhar Street, Boston, MA 02131 USA "... however it may deserve respect for its usefulness and antiquity, [predicting the end of the world] has not been found agreeable to experience." -- Edward Gibbon, 'Decline and Fall of the Roman Empire' The e$ Home Page: http://www.shipwright.com/ Ask me about FC98 in Anguilla!: <http://www.fc98.ai/>
