FIELD: information management systems.
SUBSTANCE: method for controlling import of content into a domain comprising number of devices consists in checking for the presence of a domain watermark in the content, and if the domain watermark is found in the content, refusing import of the content into the domain, and if the domain watermark is not found in the content, allowing import of the content into the domain and causing the domain watermark to be embedded into the content. 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.
EFFECT: providing a method for discerning the input of legitimate unencrypted content from illegally copied unencrypted content.
