Deniable File Systems
Many people need to transport and store sensitive data, and need to be able to deny the very existence of data on their computers. Journalists traveling through conflict zones, political dissidents, and spies all need to secure their computers against an adversary who may gain physical access to them. Some users need even to be able to have their computers examined by a forensic system. Encryption alone is not enough, when deniability is needed. To this end, the SSRC is working on a deniable file system, Matroska, which seeks to steganographically conceal data within a hard disk.
This work is a work in progress.
