[e-privacy] Identificativi univoci nella stampanti Canon a colori

[marcoc1 at dada.it]

Vi allego un estratto di Edri-gram di questa settimana,
 che trovate qui per intero
http://www.edri.org/edrigram

L'articolo riferisce che i motori Canon per stampanti
 a colori stampano in giallo, su una riga di 0,1 mm,
 un identificativo univoco della stampante.

Canon, come Adobe ed altri, ha precedenti in questo senso.

Qualcuno con accesso ad una Cano a colori (nache rimarcata)
 puo' fare un test e confermare?

Ciao.   Marco

4. Secret code added to most colour prints
============================================================

While printer-manufacturer Canon was awarded a Big Brother Award in
Germany for secretly adding a unique code to every print-out made on
household printing equipment, the practice is very wide-spread. Many
laser
printers seem to print-out a unique number on every print-out, invisible
to the bare eye, measuring only 0,1 millimetre. The Dutch police has
admitted to e-zine Webwereld that they have used these marks to detect
the
sources of print-outs, tracing individual printers through the vendor
chain. "We are familiar with this research method," said Ed Kraszewski
of
the Dutch national police agency KLPD. "We are using it in our research
and it has proven to be successful in the past."

Even though the spokesman would not give any further details on these
successes, anonymous sources confirmed to Webwereld  that the Dutch
Railway Police, part of the KLPD, is investigating a gang that could be
counterfeiting tickets on a large scale.

Although modern printers are sold under many different brand names, the
insides are very similar. Inside every machine is a print engine with a
unique and traceable identity. These engines are produced by a handful
companies, such as Toshiba Corp., Canon Inc. and Ricoh Co. Ltd.

Members of the Dutch Parliament have raised the issue on 27 October with
minister Brinkhorst of economical affairs, demanding he should publish a
list of all the involved printer manufacturers, explain why this
'feature'
is kept secret, and how he is encouraging the manufacturers to start a
public awareness campaign.
