The point is, they don't really raise the bar to counterfitting, all they do is raise the bar to legitimate use. Besides, there's always Gimp and open source software. Building in such restrictions to that software, given that the code source is available means that any serious counterfitter will recompile with out the protections. There'll therefore always be photo editing suites available which don't possess these limitations, and so there'll always be a way around it. It's the wrong approach to preventing counterfitting, it's kludgey and won't ever work well.
I guess though what it *will* do is prevent teenagers from printing out $5 bills and tossing them in the coin machine at the arcade, or any other electronic eye. This is petty theft though, and it hardly seems fair to restrict legitimate consumers, costing them ultimately hundreds of hours to lost performance or costing them the fair use of money images to save $5 here and there.
It's the same problem as DRM enabled music. It'll always be defeatable, and given that in that case there's the "analog hole" problem, will not ever stop someone serious about committing the crime, thus all it does is inconvenience or prohibit fair use.

As for preventing image copying, it seems a half-witted attempt by
bureaucrats to stop kiddyfitters... It probably wouldn't take too much
to defeat it anyway (like cut the bill into thirds, then scan each third
seperately and stitch it back to together).

Subject: HP printers and currency anti-copying measures
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://tinyurl.com/2xnno
(http://www.sanmateocountytimes.com/Stories/0,1413,87~11271~1882929,00.h tml)
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.
