Secretbook, says Wired, is “the first time anyone’s managed to figure out how to automate digital steganography - the practice of concealing messages inside computer files - through Facebook, the world’s biggest social media platform. No one will be able to parse your message unless they a) know to look for one in the first place and b) know the secret code. An add-on for Google’s Chrome browser, Secretbook lets you process a photo, embedding it with a tweet-length, password-protected message (140 characters or less) that you can then share widely to Facebook.

What if, veiled within those ever-pervasive images, was something more-a clue, a secret, a hidden message masked from prying eyes?Ī new web app, Secretbook, says Wired, enables you to do just that. Chances are, your timeline is flooded with photos: photos of food, photos of your friend’s kids, silly little images captioned with bold text and gorgeous images someone lifted from around the net. This photograph has a secret, but without the right password you’ll never learn it.
