Design With Privacy In Mind: Pixels to Keep People Out of Your Business

jonathan-ravasz-smokescreen-designboom01

Slovakian web designer Jonathan Ravasz has developed a new tool called Smokescreen to maintain privacy online, via designboom.

Smokescreen is an open source application written in Processing for generating text that is unrecognizable for the most common Optical Character Recognition (OCR) software. The application generates random “pixels” overlaid text, confusing the software but not the human readers.

…in other words, randomly generated pixels are not going to prevent your boyfriend/girlfriend/cat/dog/significant other from reading the rant you’ve foolishly left open on your screen, but if someone is scanning your e-mails externally, you can use this to block them.
