Subj: "Copier" IDs Coming Soon to Consumer Printers?
Greetings. In my recent special report, "IDs in Color Copies"
(http://www.vortex.com/privacy/priv.08.18), I related Xerox's
confirmation of "invisible" IDs embedded repeatedly in the
background "noise" of xerographic color copies and prints, from
both Xerox-produced machines and those of other manufacturers.
Included ostensibly as an anti-counterfeiting measure, these are
produced through "steganographic" (hiding in plain sight) encoding
techniques. This technology appears to be similar in a broad sense
to (but clearly not identical with), Xerox's commercial
"DataGlyphs" encoding system (see Xerox's material regarding
DataGlyphs at: http://www.xerox.com/xsis/dataglph.htm).
Response to my report has been very strong, mostly from people who
were unaware of the existence of these copier IDs. At least one
person continued to doubt that the IDs were real--sometimes it's
difficult to prove an "urban legend" as actually true!
In my report, I speculated about the eventual implementation of
such ID tracking systems within inexpensive consumer copying and
printing equipment. Readers who might have doubted the likelihood
of that eventuality may be interested in:
http://www.bep.treas.gov/countdeterrent.htm
which is a U.S. Bureau of Engraving and Printing "Request for
Proposals" regarding (among other things) implementation of tracing
systems for devices such as inexpensive and ubiquitous inkjet
printers, to encode system identification in any output.
It would seem that the time for a public airing of the complex
issues surrounding these systems is already upon us!
