Compression project >> Video Area Home

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:

• Small video distortions after hiding info.
• It is possible to extract info after video compression.
• Information is protected with passcode.
• Unique.

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. Source text

This is an example of distortions in video with 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.

Public MSU video filters Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies.
