ISRC Protection?

Hi,

Could you help us to understand how to protect our music? What would we and your customers (who have bought our music) had protection from fraudsters who can take our tracks and to publish under his own name illegally.

If we do release our tracks for example at the distributor as www.cygnusmusic.net or www.tunecore.com in this case our music will have a ISRC code and we will have protection from fraud. But tell me in this case will not suffer those who bought our music in your store?

Kind Regards,

The question arises: if we do release our track/music. This will suffer to customers? Will the buyers to claim from distributor?

Help me understand this side please.
