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

source frame with hidden info
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.
