Steganography: Deciphering Hidden Messages
http://thekojonnamdishow.org/shows/2010-07-13/steganography-deciphering-hidden-messages
Last month's arrest of 10 Russian operatives shined a spotlight on a little-known but burgeoning espionage technology known as steganography. But such 'hidden in plain sight'(or is it 'site?') messages -- like those contained in photos posted online -- are just one of many ways covert messages are being sent and received. We explore the latest in cybercrime spy technology and the challenges it presents to law enforcement.

A Food Safety and Inspection Service (unclassified) training program urged employees, including me, to spy on members of environmental groups, such as Greenpeace and PETA, and provided employees (who have no surveillance responsibilities in their job description) with a variety of computer tools to aid them in that. One of the tools was a steganography program. It seemed odd that they included the steganography program because it was designed to encrypt messages (i.e., government official communications) and not to decode messages.
When I wrote an email message to a supervisor questioning the legality of the spying, an official wrote back and said the employees should not install the software on their work computers but could use them on their home computers. Thus, there would be even less oversight of government activities that were questionable on their face.
I think kojo's picture is on the left edge of the photo near mona lisa's right ear (her perspective).
Great and informative show, as usual!
