Abstract
An outsourcing environment is described herein by which an outsourcing entity may delegate document-transformation tasks to at least one worker entity, while preventing the worker entity from gaining knowledge of sensitive items that may be contained within a non-obfuscated original document (NOD). In one example, the environment may transform the NOD into an obfuscated original document (OOD) by removing sensitive items from the NOD. The worker entity may perform formatting and/or other document-transformation tasks on the OOD, without gaining knowledge of the sensitive items in the NOD, to produce an obfuscated transformed document (OTD). The environment may then allow for the outsourcing entity to view a content-restored version of the OTD.
