Abstract
Described are computer-based methods and apparatuses, including computer program products, for secure redacted document access. A viewing application for viewing documents is executed, the viewing application comprising standard code for the viewing application that can not process the container data type, and custom code configured to allow the viewing application to process a container data type. A container of the container data type is received from a remote computing device comprising a set of redacted documents corresponding to an original document, each redacted document having a level of redaction corresponding to a viewing location, and a header comprising encryption information for each redacted document in the set of redacted documents. The container is processed based on a location of the computing device and the custom code.
