signature

Protected trigger should have the option of: a fixed signature, enter the website, or any information.
To avoid giving the key on the site B(counterfeit) at a higher price, then purchase at a cheaper price (by trickster) on site A . Then the person sending the trigger to his client.

Thank you for attention

This is similar to downloading an executable file on site B and selling it cheaper on site A, isn't it? What prevents one from doing that?
