What's the most understandable naming for these consepts?

THIS could accept key from owner, if owner continues to access THIS with initial key, it receives THIS's content. If owner changed the key, THIS rejects it and doesn't allow access to content.

When reject happens there are multiple policies.

1. Do nothing - so if owner accesses THIS with initial key, it receives content. (I called it Reproduce)
2. Ban owner, so it cannot access content with any key, but other owners can access content until they change their own key (I called it Expel)
3. Close THIS if any owner tried to access with their not-initial key. So THIS blocks access from any owner, no matter which key they use. (I called it Seal)

I develop library, which uses these 3 concepts. So I would like to name THIS and these 3 policies in developer-friendly way.

For now THIS is my library's name, which doesn't mean anything (what's probably appropriate).
