VSL update

Recently project has been migrated from Netbeans structure to Maven (along with packages refactoring). Also code has been migrated from SVN to GIT repository.

New steganographic module is on the way - fresh VSL version containing it should be released very shortly.

VSL video tutorial

You can find on PentestIt.com - http://pentestit.com/2009/06/16/video-tutorial-simple-steganography-vsl/ - VSL video tutorial. It nicely shows how simple in use is VSL.

Video introduces one of the simplest use-cases for Virtual Steganographic Laboratory - hiding data with LSB steganography in image and extracting it afterwards.

vsl-1.0 Released

VSL is a simple, easy to use software for steganography, steganalysis and watermarking. It gives scientists and students a powerful tool for conducting wide range of experiments involving different types of message embedding, diverse attacks (employing image processing algorithms) and steganalysis with the use of popular methods.

Due to its use of generics (and few other features) it requires at least Java 1.5 (5.0).... read more

Start of the project

The VSL (Virtual Steganographic Laboratory) project has started on SF. Its main purpose is using, testing and adding new techniques both for steganography and steganalysis for digital images.

Many steganographic application are usually command-line tools or very simple GUIs which consists of one choosen method. VSL provides framework for complex yet simple to arrange experiments and methods testing. It can use many methods simultaneously and everyone can add a new one.... read more
