Steganography and Flickr
This post was published 4 years 6 months 28 days ago which may make its actuality or expire date not be valid anymore. This site is not responsible for any misunderstanding.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.
