Abstract

A document store delivers a document requested therefrom from a folder having rights information associated therewith. In response to a request for a copy of the document, rights data for the copy of the document is defined based on the rights information of the folder, and the copy of the document and the defined rights data thereof are published to result in a package with the rights data and the copy of the document encrypted according to a content key (KD) to result in (KD(copy)). The formed package is then delivered to the requester. The rights data can be discovered upon the requester attempting to render the package and such discovery triggers a request for a corresponding license based on such rights data. The license includes (KD) therein in a form available to the requester to decrypt (KD(copy)) if the requester satisfies the rights data.
