No one but the sender and recipient know it's there, making its discovery much less likely. american terrorism Medias role in terrorism. When used together, the two techniques, encryption and steganography, pose a double whammy for code-breakers. With the Internet, steganography has come of age. Stego-tools-free and easily downloadable software programs-take advantage of the unused space in audio, text, image, or video files and create a secret hiding place for embedding data. american terrorism Terrorism and the media. Take an image of Osama bin Laden, for example. Then take a map. A stego-tool can be used to hide the map file under the "cover image" (stego-speak for the original file). american terrorism Types of terrorism. You have the digital age equivalent of invisible ink. Actually, there isn't much to see. Most stego-media are indistinguishable from unaltered files-which is, in fact, the whole point. An Internet surfer could be looking at a photo of a blonde bombshell and not realize he's also looking at . . . well, hidden data involving another kind of bombshell. To recover a hidden message posted on the web, the sender must first tell the intended recipient where to find the stego-media; then the recipient can extract the information using the same software that created it. Because intercepting stego-files is so difficult, and dissemination so simple, steganography has become a popular means of communication for those who prefer to fly below the radar, which includes everyone from privacy nuts who stego their regular e-mails, to the terrorists who want to stego-smuggle information around the globe. According to USA Today, electronic steganography has become so vital to subversive groups that it is taught at Afghani and Sudanese extremist camps. The idea of religious extremists concealing their plots against "the infidels" on sites trafficking in explicit sexual content is more than a little ironic. But it doesn't surprise Neil Johnson, a steganography researcher. "Any organization that has an intelligence group is going to [teach their operatives steganography]," says Johnson. The hide-then-seek-and-extract approach was used by bin Laden's followers to communicate in at least three different terrorist acts, including the 1998 embassy bombings in Kenya and Tanzania, according to U. S. officials. Not only do terrorists have high-tech know-how, they've also got the leg up on the United States, at least according to the director of the National Security Agency, Michael Hayden. "Osama bin Laden has at his disposal the wealth of a $3 trillion-a-year telecommunications industry he can rely on.
