Not just decode, but also decrypt.
You'd probably want to encrypt not just for the secrecy, but so that the noise introduced by the steganography doesn't seem so suspicious.
- ajsnigrutin 4y agoThis would work if the elevator music was a never-repeating stream. With most elevator music, it's a few minutes of a "song" playing on repeat 24/7, so if you recorded a few repetitions of the "song", you'd probably see also repeated packets on the network. If the music was repeating but the stream was different all the time, then steganography could be the reason :)
- rhacker 4y agoI haven't actually heard elevator music as much as people say it exists. In fact I don't think I've every been on an elevator that had music.
- sublinear 4y agoI think it's a trope from the second half of the 20th century (mostly the 3rd quarter).
- bigiain 4y agoPretty sure I've never heard Brian Eno playing in an airport either.
- rerdavies 4y agoTragedy. Google sez: Music for Airports was installed at the Marine Air Terminal of New York's LaGuardia Airport for a brief period during the 1980s. Elevator music may no longer be a thing, but apparently, airport music still is: https://www.youtube.com/watch?v=Km0h6Ix3Zcs https://www.youtube.com/watch?v=Km0h6Ix3Zcs
- eru 4y agoThe modern equivalent is probably mall music?
- eru 4y agoEncryption is in another layer. Basically, you'd use steganography to hide that you send a message. And that message would be encrypted. You can use almost any standard encryption scheme, as long as you remove headers etc. Any ciphertext of a crypto-system worth its salt will be indistinguishable from random noise without the key.
