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.
There are four
highly customisable algorithms in the tool, as well as an open-source
implementation of RS Analysis (an extremely good steganalysis method).
The tool has the additional advantage of being able to simulate hiding
- so you can get an accurate map of where the information is hidden.
version can be run by simply double clicking the .jar file (in Windows), or by running
at a command line with the following options (you will need to run at
the command line if you are using big pictures, such as those greater
than 500x500 pixels or it will run out of memory):
java -jar -Xmx512m diit-1-5.jar
tells the virtual machine to use 512MB of physical RAM (at most) - please
change to suit your own machine specifications.
