Securing medical and other private data in the cloud

[Ken North]

Microsoft Research has made a breakthrough in securing confidential
information stored in the cloud.

It's built a prototype storage system, based on homomorphic encryption,
that permits accurate analytics without having to decrypt the data.

For the non-mathematically inclined folks like me on the list, Robin
Houston has posted an english description of how the Homomorphic
encryption works:

Thanks Ken,

Interesting read. Has any tried the encryption on other public clouds/PaaS platforms? 

regards

Raj

IBM Research has published a helpful description of homomorphic
encryption that uses the analogy of a photographic dark room:
