How the miner knows who I am?

Hi there,
I am totally new but now have a question:
I have plotted 1TB on a external HDD with XPlotter.
When I try to use the Burst Wallet for Mining it is not working. I found out, that the reason for this is, that my CPU does not support AVX. (Phenom 2 X4).
So I installed the creepminer (https://github.com/Creepsky/creepMiner) on Linux.
I am now unsure what is the right configuration for me.
Especially, how is the miner able to determine, which Burst adress is mine.

Any help is much appreciated.

I have no experience using creepminer, but I do know that plotfiles contain the information that point to a specific account.
