Espionage just got a little more sophisticated and scientific. Invisible ink? Decoder rings? Lemon juice? Puh-lease --that's mere child's play compared to what double agents scientists at Tufts University just created
During the Cold War, the Soviets used a psychic technique known as remote viewing. Now secret messages can be hidden in genetically engineered bacteria, thanks to a new method called steganography by printed arrays of microbes. Developed by chemistry professor David Walt and his cloak-and-dagger team of researchers, this new method uses an assortment of E. coli strains modified with fluorescent proteins that glow in seven colors.
Multiply that number by the two colors each message character is encoded with, and spies like us have more than 49 possible code combinations. That's enough for the alphabet, plus digits 0 to 9, with room left over for a few extra symbols.
The secret microbial messages are first grown in petri dishes. The cultures then are transferred to a thin film and ready to be sent to the desired undercover recipient. To unlock the message, the recipient must transfer the bacteria to a genetically modified growth medium, which acts as the secret key.
Seems like a pretty smart idea. Who would have the resources to try a brute force attack on a system like that. Most people would have trouble getting the resources for just one modified growth medium. Unlike other encryption techniques, getting the answer wrong will be a waste of not just time but also materials.

Well I didn't read anything about infecting the host in the article. They say they transfer the bacteria onto a film which can then be sent off. That's how I interpreted it anyway.

Yes, but are they saying they infect the host, the host then passes on the bacteria to said target and when that person seeks medical treatment I.e. antibiotics the encryption key is unlocked?
Or am I way off base? Honestly, who sits around and thinks of these bizarre ideas?
