Video Steganography on Youtube?

Video Steganography on Youtube?

Not technically cryptography, but hiding data can certainly aid in the protection of said data, especially if the data is further protected by a modern encryption algorithm. That said, onto the question:

Would it be possible to use steganography to hide meaningful amounts of data in a video and retain that data if it were uploaded to YouTube? Would YouTube compression possibly interfere with the hidden data? If technically possible, would it be a viable method of hiding data you wanted available to anyone who knew where to look and, if applicable, knew how to decrypt the data?

And, if possible or viable, do you think it’s common? Perhaps using those copious low-quality text to speech videos?

Cryptography is the art of creating mathematical assurances for who can do what with data, including but not limited the classical example of encrypting messages so that only the key-holder can read it. Cryptography lives at an intersection of math, programming, and computer science. This subreddit covers the theory and practice of modern and *strong* cryptography, and it is a technical subreddit focused on the algorithms and implementations of cryptography.
