The practice of hiding data in images -- known as steganography -- is nothing new. People have talked about it for ages, and we've long heard reports of how nefarious organizations used it all the time. But, of course, it can also be used for perfectly good reasons as well -- and now it may have just become a lot easier to use. Glyn Moody points us to the news of a new steganography program that is designed to work easily via Flickr, with the goal of getting news reports to various countries that try to censor the internet. The program, called Collage, supposed makes it quite easy to both encrypt and decrypt information in Flickr photos, knowing that Flickr -- unlike many news sites -- isn't often blocked in countries that censor the internet.
Of course, once word of this program gets out, that could possibly change, but the programmers behind it say they can easily expand it to work with other photo sharing sites as well.
None of this is that surprising, really. In fact, my first reaction on hearing it was to think that this can't be new, as I'm pretty sure other offerings have already allowed such functionality with Flickr. However, it is a nice reminder that every time you try to censor the internet, there will be ways through, and that includes just masking the traffic you want blocked as legitimate traffic, such as Flickr photos.Permalink | Comments | Email This Story
