Steganography with Flickr

yiangocy writes "Steganography is not something new, there have been techniques and available programs for hiding data in pictures/audio files for a long time now. However, one step further is using popular online photo sharing sites, such as Flickr in hiding your data, successfully."

nothing to do with Flickr

[Petronius]

This is an interesting article, but it has nothing to do with Flickr, except for the fact that instead of saving the images on a local device, this guy uploaded them to Flickr.
Yaaaawn, -1: misleading.

Movie Plot Vulnerability

[Mr_Icon]

Ho-hum. There are much better ways to back up your data for $25 a year.

This is a general "this can be used by terrists!" freak-out. Well, you know, this is an awfully stupid and ineffective way to pass information -- something Bruce Schneier likes to call "movie plot" vulnerabilities. Why bother with steganography when there are much better means to pass encrypted data between two people? Like, I don't know, DCC'ing a file over IRC, or just plain sending an email? If you own both the sending and receiving servers, or use one of the infected army of the drones, there is a miniscule chance of your message even being observed in the ocean of the information that is the internet. Much less stupid than using a complex routine to hide data in an image, and then upload it to a central service like Flickr for all to see (it shows up immediately in the "recently uploaded" pool).

This is a fine idea for a movie plot, but utterly dumb for someone to actually try this. Thus, I assign the article a -1 Troll.
