What is Digital Invisible Ink Toolkit
“The Digital Invisible Ink Toolkit is a Java steganography tool that can hide any sort of file inside a digital image (regarding that the message will fit, and the image is 24 bit colour). It will work on Windows, Linux and Mac OS because it is written in Java and thus platform independent.”
