Optionally, re-importing into the "original" domain might be allowed. The method further comprises refusing import of the content into the domain if the domain watermark is found in the content unless the identifier matches an identifier for the domain. Other payloads in the domain watermark can be used to e.g. implement location- or time-based restrictions on import. |
