The messages can then be decoded through a password that the user creates, which means you will actually be able to publically share images that to the layman is just a picture, nothing more. While this sounds like a cool idea, we can only imagine that it could lead to company employees leaking secrets and sharing information meant to be private, but according to Campbell-Moore, “The goal of this research was to demonstrate that JPEG steganography can be performed on social media where it has previously been impossible.”
As it stands, the Secretbook browser extension is only available for Google Chrome and is limited to 140 characters, about as long as a text message, meaning that lengthy and complex secrets might be harder to be leaked. Campbell-Moore admitted that while it is possible that terrorists could use Secretbook for nefarious purposes, the fact that it is not completely foolproof could deter them. Like we said, it sounds interesting but could potentially be dangerous, but if you want to check it out anyway, the extension is available via the Google Chrome Webstore, or you can head on over to Wired’s Danger Room for the details.
