I really have no problem with sharing my information openly in cases my presence has an obvious effect on those around me. Letting other cars within a certain radius know where I am seems a reasonable sharing of my information. I would go as far as sharing my intended destination so that some "cloud" some where can better plot my route to minimize traffic for me and others. That said, storing all that information for later analysis, which is possible given what I've shared, would be an unreasonable use of my data (unless it's done as part of some aggregate information). The problem of course is that once I share that information I lose control of how it is used later. If someone can devise a way for me to share my information while controlling how that information can be used later, it would go a long way to striking the right balance. I guess that's more or less "personal DRM" for our information.

I think the difference is consensual sharing of the information. Many would probably be OK with certain types of information collection, but the way some things are collected without overt notice or consent (Example: Wi-Fi SSID to GPS long/lat pairings on phones) is understandably concerning to some.

It would not be easy to do this in a technical manner, as it could be defeated (as with most DRM). It sounds like a legislative solution would be best.

-> Homomorphic encryption is an active field of research. Legal is most likely the better solution. Probably.
