How do apps like Spotify prevent the files of downloaded content from being found, duplicated, and illegally distributed?

In: Technology

Files aren’t in mp3 even if you find them you can’t use them, they are in unique formats and encrypted only Spotify app can read them

They encrypt the local files but it’s easily broken- you could also setup a loop to record any songs to mp3. Its possible to convert YouTube to mp3 just as easily.

This isn’t important though. Spotify and Apple Music and even Netflix prevent piracy because they are reasonably priced and provide a lot of value. If music was still $15.00 a cd people would pirate a lot more; if all the albums ever made are easily accessible for $10 a month, most people would pay for that service.

The content is obfuscated and the code to decrypt it is partly held on their private servers and cached in a trusted privacy module for offline decryption.

This module is essentially a secure chip on your system that doesn’t trust your device, only the specific process that is properly signed by Spotify.

So to decode the file, you have to either be trusted by the TPM, or be really really good at factoring large numbers.
