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:

    The number of errors decreases when you increase redundancy!


    This is an example of distortions in video with info.     [an error occurred while processing this directive]

    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.
