Governments, including the United States, already use the hidden markings to track counterfeiters.&quot; According to the article, the high fidelity of outputs from color machines to their original documents suggests that counterfeiters can potentially succeed in creating high-quality counterfeited currency and government documents using these machines. At the request of the United States Secret Service, manufacturers developed mechanisms that print in an encoded form the serial number and the manufacturer&#039;s name as indiscernible markings on color documents. The Secret Service and manufacturers would be able to decode these values from the markings and in the event a color machine was used to print a suspected counterfeited document, these values would be used with customer information to discover the identity of the machine&#039;s owner. </p><p><br /></p><p><a href="http://w2.eff.org/Privacy/printers/index.php" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://w2.eff.org/Privacy/printers/index.php" rel="nofollow">http://w2.eff.org/Privacy/printers/index.php</a></p><p>Update, Dec 5, 2005</p><p>Updated printer list </p><p><br /></p><p>Update, Oct 13th, 2005</p><p>Learn to decode Xerox DocuColor tracking dots using our guide - or use our decoding program to decode them. </p><p>Imagine that every time you printed a document, it automatically included a secret code that could be used to identify the printer - and potentially, the person who used it. Sounds like something from an episode of &quot;Alias,&quot; right? </p><p><br /></p><p>Unfortunately, the scenario isn&#039;t fictional. In a purported effort to identify counterfeiters, the US government has succeeded in persuading some color laser printer manufacturers to encode each page with identifying information. That means that without your knowledge or consent, an act you assume is private could become public. A communication tool you&#039;re using in everyday life could become a tool for government surveillance. And what&#039;s worse, there are no laws to prevent abuse.[/QUOTE]</p><p><br /></p>
