Steganography and Flickr
For those that do not know what Steganography is:
Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message; this is in contrast to cryptography, where the existence of the message itself is not disguised, but the meaning is obscured. [via]
Apparently individuals can utilize special utilities to disguise files within a totally different file. According to the linked weblog, Flickr users are able to encrypt files – such as PDF, DOC’s, ect – within images. Flickr does not scan for altered image files. Do I see Flickr “file sharing / hosting” for the paranoid? Remember that Flickr supports image uploads up to 10 MB.
