Access rights to content items, such as personal photos etc, is determined in response to content metadata and requester metadata. A plurality of content items is stored in a content item store. An access right processor determines content metadata for the plurality of content items. When a request for a content item is determined, the access right processor determines requester metadata for the request. The requester metadata comprises data of a characteristic of a requester of the request. The access right processor then determines access rights in response to the content metadata and the requester metadata. If a positive access right is determined, the requested content item may be sent to the requester.
