Abstract
Described are computer-based methods and apparatuses, including computer program products, for adaptive document redaction. A container is generated 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. A request to view the original document is received from a requesting device. The container is transmitted to the requesting device. A request for additional encryption information for a redacted document from the set of redacted documents is received from the requesting device, wherein the redacted document comprises a level of redaction for a viewing location that is equal to a location of the requesting device. The additional encryption information is transmitted to the requesting device.
