Facebook is a place where you can share pictures of cute animals and fun activities. Now there’s a browser extension that lets you encode those images with secret, hard-to-detect messages.

That’s the idea behind Secretbook, a browser extension released this week by 21-year-old Oxford University computer science student and former Google intern Owen-Campbell Moore. With the extension, anyone — you, your sister, a terrorist — could share messages hidden in JPEG images uploaded to Facebook without the prying eyes of the company, the government or anyone else noticing or figuring out what the messages say. The only way to unlock them is through a password you create.

“The goal of this research was to demonstrate that JPEG steganography can be performed on social media where it has previously been impossible,” Campbell-Moore tells Danger Room. He says he spent about two months spread out over the last year working on the extension as a research project for the university.
