Your Printer Can Identify You
from the for-all-your-forgers-out-there... dept
It used to be that every typewriter had its own unique "fingerprint" that could identify which document came from which typewriter. Now, some researchers are suggesting the same thing may be true for printers. They've already worked out a system to identify laser printers, and are planning to do the same with inkjet printers. The issue is that the quality of manufacturing for cheap printers isn't nearly good enough to avoid certain unique characteristics. It doesn't seem to be able to perfectly pick out the correct printer every time, but authorities are hoping such solutions may help them to catch counterfeiters and forgers who have been using cheap printers more and more these days.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.
–The Techdirt Team
