Secret code 'traces copies'
19/10/2005 12:37 - (SA)
San Francisco - A secret code embedded in many colour laser jet printers allows the US government and any other organisation capable of reading the cipher to identify when the copies were made and on which particular machine, according to research conducted by the Electronic Frontier Foundation (EFF).
The San Francisco-based privacy organisation said it had detected almost invisible patterns of yellow dots on every document printed on the affected machines that could indicate when and where the print was made.
Among the copiers found to include the secret yellow dots are ones made by Brother, Canon, Dell, Epson, HP, Konica/Minolta, Kyocera, Lexmark, Ricoh, Tektronix/Toshiba and Xerox.
The foundation cautioned that though it had deciphered the code on Xerox machines, it had not done the same for the yellow dots found on other copiers, but that it was likely that they too represented a sophisticated document tracking system.

Small Galaxy Punches Hole In Andromeda

Sometime in the distant past, the dwarf galaxy M32 hurled itself at its much larger neighbor Andromeda, delivering an explosive uppercut punch that left a jagged hole nearly 10,000 light-years across in Andromeda's plane of stars, one that millions of years later has yet to fully heal.
New infrared images from NASA's Spitzer Space Telescope recently revealed the hole, which is hidden to optical telescopes behind Andromeda's veils of cosmic dust and gas.
The Spitzer images also revealed other features of Andromeda that have never been seen before, including bright, new stars and spiral arcs swirling out from the galaxy's center.
'Andromeda is a far more exciting, dynamic place than we ever thought,' said Karl Gordon, an astronomer at the University of Arizona's Steward Observatory and lead author of a new study detailing the findings. posted by Gary Williams at 1:38 PM | link |
