MSU StegoVideo

Unique tool for hiding information in video
(VirtualDub filter/standalone executable)

MSU Graphics & Media Lab (Video Group)

Project, ideas: Dr. Dmitriy Vatolin
Implementation: Oleg Petrov

MSU StegoVideo allows hiding any file in a video sequence.
Different popular codecs were analyzed and an algorithm, providing the smallest data loss after compression, was chosen. Convolutional codes with Viterbi decoding are used to correct occurred errors.

Main features:

You can use MSU StegoVideo as VirtualDub filter or as standalone .exe program, independent from VirtualDub. Click links below for instructions:

    This is an example of extracted info.
    # denotes symbol with mistake. In real file you will see any symbol in this place.

    Data hiding, a form of 
    steganography, embeds
    data into digital media for 
    the purpose of identification,
    annotation, and copyright.

    The number of errors decreases when you increase redundancy!


    This is an example of distortions in video with info.

    compressed frame with hidden info (DivX5 768)
    compressed frame with hidden info - information was completely recovered!

    Quality of information extracted from compressed video depends on codec, data redundancy and frame size. The greater information redundancy, the greater probability of extracting file info without errors.
