Question

hi every one i need help in my project of media protection . just for e.g. i have an encrypted mp3 file which i will decrypt in real time using a service or something . my problem is how do i play the decrypted mp3 file . of course i cant decrypt the whole file . so do u have any idea about some library which i can use to play ,say conents of a buffer where i will store my decrypted mp3 fragment.. any idea will do a lot..

Answer 1

It doesn't work like that, either you decrypt it completly or you don't.
Instead of showing a real demonstration why no show a visualization of the scenario since the creation of the media until the discovery of the message and implications and publishing?

Answer 2

I dont understand your question

Answer 3

Well if i decrypt the whole file then dont u think the very process of encrypting it or protecting it from being copied will be left useless. If i decrypt the whole file then some one can very easily spot the decrypted file and then copy it from on system to another . Then there is no protection.
My idea is that i will decrypt only say 20-30 frames at a time and save it to a buffer . then i call a library function to play this buffer . in just a way i can use multiple buffers and keep the player busy till the whole media is played. My point is i will be decrypting only some part of the mp3 file not the whole file and then play it and after that again decrypt remaining segments. and most importantly these segments must be in memory so that they are protected from being copied ..
Any way thanx fr ur response..
