Serial numbers hidden in color photocopies
Two years ago, there was a report that Xerox color photocopiers would embed a hidden record of each copier's serial numbers into each copy it produced. Although this was fairly widely documented, some people persist in disbelieving it. So today, in the course of a discussion about the IFPI, SIDs, and trade sanctions against the Ukraine, I decided to ask Xerox. Xerox's response clearly indicates that the claims are true:
The Secret Service has the ability to track a particular document to the source equipment that has produced a suspect image. This information is used for criminal investigation purposes only. The Secret Service does not provide this information to private individuals or companies, nor do they allow other parties to access this information. To detail how these anti-counterfeiting systems work would only encourage the illegal acts they are designed to prevent.
