We have a audio study material of about 50 hr duration, we want to load this into micro SD card and market it, but we need to have a software for securing the audio files from copying and piracy.
We want software for :
1. The Audio files should be made NOT copyable from the micro SD card. The Audio files should play only in the Mobile/MP3 player - where they are installed first.
2. The Audio files should be made available for downloading online. But should NOT be copyable.
