Imagine you’re sitting on an airplane, using webmail to send your marketing plan to your boss, when you notice that the passenger sitting next to you has wandering eyes.
Or you’re sitting in a crowded cafe, looking up information online about a medical condition.
Your seatmate might be spying on your company’s intellectual property, or a passerby might unintentionally discover something you really don’t want them to know, like your private health information.
This kind of data leakage is why some people use privacy shields to obscure their computer screens with a dark plastic film. But those privacy protectors aren’t perfect (they prevent reading from the side, but not from someone directly behind you).
Now there’s a Chrome browser extension called Decodelia that obscures your web content under wavy lines and patterns, making it unreadable to anyone without red tinted glasses:
A Chrome extension and glasses set that obscures your web content.
Freely browse without fear of judgement or loss of privacy from those around you.
DECODELIA renders your screen indiscernible without red tinted glasses.
Decodelia was created by Melanie Hoff, an artist and photographer interested in digital imagery and “social hacking.”
Hoff frequently works in public cafes in New York City, and recognized that privacy of information doesn’t just concern data sent over the internet, telling Motherboard:
There’s a lot of talk about privacy related tools and techniques that deal with our information that happens behind our screen, as in what we send out to the internet. And there isn’t that much interest or talk around the physicality of our screen – when we’re in public spaces people can see that.
Decodelia reveals the content of your browser only when you’re wearing red tinted glasses, similar to the way 3D glasses render clearly images that look blurry to the naked eye.
Hoff’s browser covers the screen with the same type of wavy patterns that banks use on the inside of envelopes to prevent snoops from reading your checks through the paper.
So far, there aren’t a lot of Decodelia customers – just 20 people are using it, according to the Chrome Web Store.
However, one five-star review from user Dhruv Mehrotra hints at why Decodelia could become much more popular:
Not only has this application increased my productivity, it has reinvigorated my meager sex drive [by] allowing me watch my favorite nudie videos everywhere I go. Thanks MAH845, you are a hero.
