What is Chameleon?

Chameleon is an image steganography software developed by Mark David Gan for his Computer Science Thesis at STI College Bacoor, a computer college of the STI Network in the Philippines.

Steganography is the art and science of hiding the existence of information.

Classic examples of which include the use of invisible inks in hiding secret messages within conventional letters.

For more information about steganography, visit the sites listed in the links section.

Chameleon uses an adaptive encoding technique based on the concept presented by Yeuan-Kwen Lee and Ling-Hwei Chen in the paper "High Capacity Image Steganographic Model". Detailed discussion of this novel technique is provided in a technical paper available in the downloads section.

Chameleon is freeware and is available for download both as compiled software and as source code.

Chameleon can be used to hide practically any type of file within a true-color bitmap. Along with integrated file compression and data encryption, this feature provides a highly secure method for establishing covert communications over the Internet and other digital channels.
