Lock content in MP3 player
I want a standard credit card MP3 player turn into a tourist guide.
I want in credit card MP3 player to put content which I locked.
No one can access the content (delete, edit, record ...) except me.
Thus, the locked file can not nobody change or delected. Just me.
I need to have software for this function.
It is desirable to make the software I can have a multilingual audio guide.
If I want to have, for example. 4 different languages with 20 mp3 files, it is necessary to make four directories. In each directory I put 20 files in a different language (one folder 20 mp3 files in English, in another directory 20 mp3 files in French, etc ...)
The combination of buttons on the MP3 player for I choose the language I would use.
Multilingualism is a desirable option if possible.
I want to buy for example. 1000 of Credit Cards MP3 player.
I have a special audio tracks that I want to put in any MP3 player.
User can listen to these audio tracks when using MP3 player.
All know, of course, if he puts MP3 player on PC computers, it becomes an external drive.
Each user can copy and modify content
If he is connected MP3 player via the USB cable to a PC computer, I do not want him to see these audio files.
Because he can use these audio files for his needs.
Therefore, these audio files to be hidden into directory of the MP3 player.
So, I want a system where only Ican import content from a PC computer into MP3 player and "lock up" and hide content.
The user can listen the content via the MP3 player, but when the MP3 player is connected to a PC computer, user can not accessto the content.
Only I can modify the content when I want through the tools that I'm looking for.
