BlindSide Cryptographic Tool
BlindSide is an example of the art of Steganography - the passing of secret messages in a form such that one would not suspect the message is being passed. This is an area of cryptography that is attracting considerable interest of late. The Blindside utility can hide a file (or files) of any variety, within a Windows Bitmap image (BMP file).

MSU StegoVideo allows to hide any file in a video sequence. When the program was created, different popular codec’s were analyzed and an algorithm was chosen which provides small data loss after video compression. You can use MSU StegoVideo as VirtualDub filter or as standalone .exe program, independent from VirtualDub.
