Steganography hot: hiding in plain view?
Text at hotjobs at Yahoo includes:
Not to be confused with stenography, steganographers study computer files that look normal (perhaps a picture of your cat), but actually contain a hidden meaning (the map of security at the local airport). Unlike typical decryption efforts, steganography investigators must first figure out if an image is normal or not.
No matter what your specialty within cybersecurity, you'll need to be flexible as the industry changes and capable of thinking outside the box, says Sean Smith, director of the Cyber Security and Trust Research Center at Dartmouth's Institute for Security Technology Studies. Smith looks for someone who might get a model airplane kit, and makes a rabbit out of the pieces instead.
For a career in cybersecurity, education options range from online certificate offerings to intensive master's or Ph.D. programs.
One can also consider US 7,277,468 which notes The invention relates to steganography, data hiding, and authentication of media signals, such as images and audio signals.
Also, US 7,273,169 states:
In a steganographic embodiment the snowy image is such that it is hidden in the photographic image of the person on the card. More detailed information as to steganography can be found in U.S. Pat. No. 5,613,004 and the references cited in this document. For the sake of the present invention steganography will be understood to relate to any method of obscuring information that is otherwise in plain sight. The information is hidden in another medium. It is used as an alternative to encryption. E.g., spreadsheets or graphics files could contain a text message invisible to an unaware person. People unaware of the hidden information will not recognize the presence of steganographically hidden information even if the information is in plain view.

Hi Lawrence,
Is this patent really valid?
For the sake of the present invention steganography will be understood to relate to any method of obscuring information that is otherwise in plain sight.
Steganography has been around for hundreds of years, can such a general patent for an existing concept really be granted?
