Elliot is hacking people in his life and stores all the information he finds on CDs. Then he labels them with classic band names.
Many wonder why he does it and how sure that is.
The answer is that Eliot hides the data on these CDs. He actually copies music to these CDs and then adds encrypted information that only he can recover. Anyone who finds the CDs sees and hears only audio files and can not find or retrieve the hidden information. In this way, Elliot’s information about his friends and acquaintances is protected from the prying eyes of law enforcement agencies.
Steganography with digital media
What Elliot does is known as steganography, the practice of hiding information in another digital medium (audio, video or graphic files).
Espionage and terrorist organizations have been using this technique for many years. In the episodes of Mr. Robot Elliot uses the software “DeepSound” to hide information in his audio files.
DeepSound could be used as copyright marking software for Wave, Flac, WMA, Ape and Audio CDs. DeepSound also supports encrypting secret files with AES-256 (Advanced Encryption Standard) to improve privacy.
The application also includes an easy-to-use Audio Converter module that can encode multiple audio formats (FLAC, MP3, WMA, WAV, APE) for others (FLAC, MP3, WAV, APE).
