The Jigsaw secure distributed file system [TM Equivalents?]

The Jigsaw secure distributed file system by Jiang Biana and Remzi Seker.

Abstract:

The Jigsaw Distributed File System (JigDFS) aims to securely store and retrieve files on large scale networks. The design of JigDFS is driven by the privacy needs of its users. Files in JigDFS are sliced into small segments using an Information Dispersal Algorithm (IDA) and distributed onto different nodes recursively. JigDFS provides fault-tolerance against node failures while assuring confidentiality, integrity, and availability of the stored data. Layered encryption is applied to each file segment with keys produced by a hashed-key chain algorithm. Recursive IDA and layered encryption enhance users’ anonymity and provide a degree of plausible deniability. JigDFS is envisioned to be an ideal long-term storage solution for developing secure data archiving systems.

Very interesting!

Reminds me that data could be split into topics, which only merge if you know the basis for meaningful merger. Otherwise it is a schema-free bag of tuples. 😉

In other words, you know someone in a population of 10,000 medical records is HIV positive but without the proper merging key, it isn’t possible to say who?

I first saw this at Datanami.
