There’s an Invisible Tracking Code Embedded in the Documents You Print

Every job contract, term paper, and yard sale flyer you’ve printed at home may have something in common. According to Quartz, several big-name printer companies have been embedding hidden tracking codes in documents for decades.

The practice is no secret: It was first called to the public’s attention by an article that ran on PCWorld in 2004. That report revealed that Xerox embeds sequences of tiny yellow dots on every sheet of paper that passes through one of their copiers or laser printers. Known as printer steganography, the clusters are staggered about an inch apart across the entire page, but with each circle spanning a millimeter in size they’re impossible to detect without the proper equipment. If they were blown up and made darker you’d be able to see an encoded message containing the serial number and manufacturing code of the source printer.

Unless you use your printer for illicit purposes, this likely isn’t something you need to worry about. The codes are there to make it easier for the Secret Service to track counterfeiters. "It's a trail back to you, like a license plate," Peter Crean, a former senior research fellow at Xerox, told PCWorld.

With the advent of the color printer came a new way for felons to forge money and legal documents. Coded dots were first used to combat this problem in Japan, and they became standard in Xerox color printers sold in America in the mid-1980s.

Printer manufacturers aren’t obligated to implement the technology by law, so there’s a chance it's missing from your computer. There’s also no law forcing companies to be upfront about this hidden feature, so if your printer does have it, it may be difficult to tell. One way to check is with a blue LED light and a magnifying glass: If the yellow dots show up you can be sure that page is traceable back to your printer, whether you mail it across the country or staple it to a telephone pole.

6 Fun Backgrounds to Use on Your Next Video Call

If you’re struggling to find a perfectly decorated wall in your house to serve as the backdrop for your video calls with friends, family, and coworkers, we have good news: Video conferencing platform Zoom lets you customize your very own virtual background.

To do it, log into your Zoom account, go to “Settings” on the left side of your screen, and choose the "Meeting" tab. Scroll down to the “In Meeting (Advanced)” section, and then scroll down farther to make sure the “Virtual background” option is enabled. After that, open the Zoom application on your desktop, click on the “Settings” wheel in the upper right corner, and go to “Virtual Background.” There are a few automatic options, but you can choose your own image from your computer files by clicking on the plus-sign icon.

Now, the only thing left to do is decide which image will best set the tone for your next video call. From the New York Public Library’s Rose Reading Room to Schitt’s Creek’s Rosebud Motel, here are six of our favorites.

1. The Rosebud Motel lobby from Schitt’s Creek

You can imagine that David is just out of frame, doing his best to carry on a silent—albeit with lots of expressive gesturing—conversation with Stevie at the front desk. (More Schitt's Creek backgrounds here.)

2. Carl and Ellie’s house from Up

If you’re hoping to create a calming atmosphere, look no further than the cozy little sitting room where Carl and Ellie grew old together in 2009's Up. (More Pixar backgrounds here.)

3. The attic study from Knives Out

If your own study isn’t quite teeming with intriguing souvenirs and leather-bound volumes, feel free to borrow this one from the mansion in 2019’s Knives Out. (More Knives Out backgrounds here.)

4. The USS Enterprise from Star Trek

Blame your spotty internet connection on the fact that you’re traveling through the galaxy at the speed of light with this background from the bridge of Star Trek’s USS Enterprise. (More Star Trek backgrounds here.)

5. The New York Public Library’s Rose Reading Room

Bibliophiles who can’t make it to the library can still pay a virtual visit to the sumptuous Rose Main Reading Room at the New York Public Library’s iconic Fifth Avenue location. (More New York Public Library backgrounds here.)

6. The Werk Room from RuPaul’s Drag Race

Dazzle your coworkers by calling in from the vibrant room where all the magic—and most of the drama—happens on RuPaul’s Drag Race. If you happen to be decked out in an ensemble made entirely of things you found at the Dollar Store, even better. (More RuPaul's Drag Race backgrounds here.)

Turn Your Favorite Photos Into Works of Art With Google’s Art App

If your local art museum is closed, a new app from Google Arts & Culture will make the photos in your camera roll worthy of gallery consideration. As Gizmodo reports, the Art Transfer feature uses artificial intelligence to reimagine any image you upload in the style of a famous artist.

If you've already downloaded Arts & Culture for Android or iOS, hit the camera icon at the bottom of the app and select Art Transfer. From here, you can either snap a photo or choose an existing picture saved on your phone. Google then gives you a variety of art styles to choose from. You can transform your cat into Edvard Munch's The Scream, for example, or turn your brunch pic from last month into a piece of Yayoi Kusama pop art.

The feature doesn't just apply filters; it uses machine learning to edit the colors, textures, and even shapes in the image you upload.

Two years ago, Google Arts & Culture rolled out a similar feature that matched users' selfies to their art lookalikes. The difference with this one is that instead of showing you existing art, it creates an entirely new image by combining your photo with a famous artwork.

You can download Arts & Culture for free today from the App Store or Google Play. After having fun with the new feature, you can use the app to virtually explore landmarks, museums, and other cultural institutions from the comfort of your home.
