The magicnumber ™ image encryption system is expected to be widely used for communication, personal computers to protect privacy. News: the trial version is available for downloading (02-01-2010).
Invisible watermarking trial version to come
The encrypted watermark with lower intensity is added to host image. The watermarked image shows no visible difference to the original one.
Irreversible watermarking trial version to come
This new technology is based on new nonlinear heat equations, which yield no blur to the evolved images. The watermark can not be removed since the system is a nonlinear one.
