I it was reported a while ago that photoshop has the built-in ability to detect that an image is of American currency. Now a Richard M. Smith at bugtraq posted that many Hp printers can do the same. If trying to print currency they’ll do just an inch of the picture and then abort the print job. The drivers contain the URL http://www.rulesforuse.org. After describing the odd behaviour, he poses some interesting questions:

1. Besides graphic programs and printer drivers, what
other kinds of software is this currency anti-copy
technology being embedded in?
2. Are companies being required to include currency
anti-copying technology in their products? If not,
what incentives are being offered to companies to
include the technology on a voluntary basis?
3. Will future versions of this technology, “phone home”
to the rulesforuse.org Web site with details about
a violation of the currency copying rules? It would
be very easy to include an email address, name of the
image file, software version number, etc. embedded in
a URL to the rulesforuse.org when a violation has been
detected.

[Spoilers] Hp printers and currency anti-copying measures
By “Richard M. Smith”
Hi,
Last week, the Associated press reported that Adobe has incorporated
anti-copying technology in their photoshop CS software which prevents users
from opening image files of U.S. and European currency. Here’s the article:
Adobe admits to currency blocker

(http://www.sanmateocountytimes.com/Stories/0,1413,87~11271~1 882929,00.html)
I did some investigating on my own computer and discovered that Hp has also
been shipping currency anti-copying software in their printer drives since
at least the summer of 2002. I have an Hp 130 photo printer and found the
string “http://www.rulesforuse.org” embedded in the driver.
According to a few newsgroup messages posted in 2002 and 2003, folks are
seeing this URL printed out when they attempt to print images of certain
types of bills. An Hp printer with this anti-copying technology only prints
out an inch of a currency image before aborting the print job.
Here is a list of Hp printers which appear to have this anti-copy technology
embedded in their Windows printer drivers:
Hp 130
Hp 230
Hp 7150
Hp 7345
Hp 7350
Hp 7550
I suspect the list of affected Hp printers is much longer.
I located these printer drivers simply by searching all files in my Windows
and program Files directories for the string “rulesforuse”. If other folks
run this same experiment, please let me know of other programs which appear
to contain currency anti-copy technology.
There are some unanswered questions raised by this quiet effort by U.S. and
European governments to turn home computers into anti-counterfeiting “cops”:
1. Besides graphic programs and printer drivers, what
other kinds of software is this currency anti-copy
technology being embedded in?
2. Are companies being required to include currency
anti-copying technology in their products? If not,
what incentives are being offered to companies to
include the technology on a voluntary basis?
3. Will future versions of this technology, “phone home”
to the rulesforuse.org Web site with details about
a violation of the currency copying rules? It would
be very easy to include an email address, name of the
image file, software version number, etc. embedded in
a URL to the rulesforuse.org when a violation has been
detected.

More disturbing is that simply blocking the printing of currencies is
not the right thing. There are in fact only limits on how close a
currency is allowed to be reproduced. There is no law or regulation
(at least for the Euro) that prohibits reproducing the bank notes in
general.
For example you are explicitly allowed to reproduce Euro notes if:
1. it is only reproduced electronically (ie. Website) when the
resolution is not higher than 72dpi
2. it is only printed one-sided and it is at most 75% or at least
125% the size of the original
3. it is printed double-sided and it is at most 50% or at least
200% the size of the original
4. is is printed on something that clearly is not paper and does
not look and feel like real bank note paper (here it can be a
100% size reproduction)
5. some more possibilities…
Thus a wholesale blocking of the printing or editing of currency
images is neither required nor correct and denies legal and fair
use.
Reproducing at least the Euro currency IS LEGAL provided the rules
are followed.
