I have been wondering about this re my utility meters. Currently my teleswitch (http://en.wikipedia.org/wiki/Teleswitch) enabled electricity meter is read a few times a year, and these readings are clearly the properly of my provider. However in an IOT world my electricity consumption would be continuously available as part of maximising use of solar or off peak rates etc. But who owns my consumption data? No doubt my provider, who owns the meter, would find somebody to sell it to and equally, various 'security' agencies would insist they had to have full access to it. I am sure that careful examination it of could reveal tons of personal info.
