Hiding messages in plain sight

The BBC writes that steganography, a technology that can "hide" information in plain sight on printed images, has begun to see the first commercial applications - including in a cameraphone.

"Japanese firm Fujitsu is pushing a technology that can encode data into a picture that is invisible to the human eye but can be decoded by a mobile phone with a camera.

Fujitsu's technique works by taking advantage of the sensitivities of the human eye, which struggles to see the colour yellow.

The company believes the technology will have spin off implications for the publishing industry.

"The concept is to be able to link the printed page into the digital domain," said Mike Nelson, general manager for sales operations at Fujitsu Europe. "
