    Abstract: An electronic file includes a page rendered version of a document and at least one unreferenced object embedded therein. The unreferenced object serves as a virtual watermark with respect to the electronic document. The electronic file may be an electronic file in Portable Document Format. The at least one unreferenced object may be an XObject. The electronic file of also may include at least one fixed location referenced object and at least one variable location object. The unreferenced object may be a placeholder object configured to be populated with a specific value in a subsequent production process while the electronic file remains encrypted. The unreferenced object may include information that identifies a location for at least one other object.

    Abstract: A system and method for controlling access to image metadata is disclosed, where metadata elements are defined for an image. The method and system include associating users who will access the image with roles, and associating the roles with individual metadata elements. In response to receiving a request for access to the metadata by a particular user, the user's role is determined from the request and the user's role is compared to the roles associated with the metadata elements to determine which metadata elements to make available to the user.

    Abstract: A method and apparatus of image processing includes first and second memories and first and second copy protector units. The first memory stores a first reference value representing a first characteristic quantity of a predetermined background dot pattern. The first copy protector unit performs a first copy protection operation for detecting a characteristic quantity from an image, comparing the characteristic quantity with the first reference value, and determining whether the characteristic quantity is identical to the first reference value. The second memory stores a second reference value representing a second characteristic quantity of the predetermined background dot pattern. The second copy protector unit performs a second copy protection operation, different from the first copy protection operation, for detecting a characteristic quantity from the image, comparing the characteristic quantity with the second reference value, and determining whether the characteristic quantity is identical to the second reference value.
