Systems and methods are provided for encrypting electronic files during a transfer to a low-security storage location is provided. In one embodiment, a method comprises receiving a file copy request for a file stored on a source storage system to be copied to a destination storage system; determining a desired file security level of the file based on a desired security level for the file when the file is accessed; determining a destination security level of the destination storage system; comparing the file security level and the destination security level; encrypting the file to create an encrypted file when the destination security level is less than the file security level prior to copying the file; and copying at least one of the file and the encrypted file to the destination storage system as a function of the comparison of the file security level and the destination security level.

File protection using session-based digital rights management

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.

Secure redacted document access

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.
