Maps can be signed by the creator to ensure they cannot be copied and that credit is always given to the original creator in the maps item lore.
  1. 1.
    Create your map as you normally would.
  2. 2.
    Use /sign or /copyright while holding the map.
  3. 3.
    Your map will be signed with your username and it will then be impossible for anyone except for you to make copies of that map.
  4. 4.
    Cover or remove the map art so that other players cannot go there in the world to create their own maps of your build.
