Thank you for your help.Please lend me your wisdom.
It is currently under development at Unity, but
On Android/iOS,
①How to play mp3 files with a zip password on AudioClip etc.
②How to play mp3 with byte[] on AudioClip etc. (read www from zip archive and become byte[])
Or
③How to copy guard mp3 files
I'd appreciate it if you could figure out any of them.
I would like to ask for your advice if there is any possibility, whether it is a plug-in call for java, Objective-C.
Thank you for your cooperation.
mHow to copy guard mp3 files
Depending on what level of protection you're looking for, if it's the best technology you can achieve, you'd better use DRM technology like Microsoft's PlayReady.
As far as I know, a perfect copy guard is impossible as long as it is mp3.
The zip password is over once it's decrypted.
(Even if it's an old PC, it can be deciphered in a few hours if the password is up to 8 characters.)
when mp3 data is available for download to the client
You can copy and play.
That's why there are many ways to embed security (DRM) in the codec itself.
If copy guard is required, the desired security can be granted.
We recommend that you re-encode and distribute it.
If you insist on mp3, you can add DRM and create an encrypted mp3 format.
You may not be able to call it mp3, but unless it is decoded, you can only compress and regenerate it with your own special product
