I am working on an application that connects to a media site and downloads mp3 files to the user's phone. I would like the user to not be able to copy these files from the phone, but only listen to them through my application.
I am currently trying to encrypt files using DES, encrypt and decrypt and play the file in bits in the application. This, however, does not work. Is there a better way to achieve my ultimate goal or has anyone else implemented a similar solution?
thank
