Re: Bullshit Alert
"...the keys aren't available"
Someone please correct me. If this data is encryped, but being used by cloud based analysis applications, then those cloud based applications must have the keys necessary to access the data (I accept that using the data from, for example, GP surgerys. there is scope for keys to be on the surgery's systems, and presented for every request, but that does not cope with bulk analysis mentioned here).
And they're in the same cloud, so if someone really wants the data, they half inch the data and the keys (OK, you could go down the rabbit hole of needing a key to decrypt the key store in the cloud, but how often do you go round this loop until you must store a key somewhere readable).
So where is the security?
I'm sure I must have missed something, so I'm asking for someone to point out where I'm being stupid?
