If I understand this correctly, this could keep government agencies from continuously monitoring devices. It'd be more like a snap-shot rather than an uninterrupted timeline. I'm quite sure this is not what government agencies want. Although President Obama recently said at SxSW that what law enforcement agencies need is the equivalent of private property search warrants I think what the actually want is more akin to a master key that allows them wholesale access whenever they want. So, they probably won't resign themselves to anything less. Besides, this approach still doesn't solve the problem of who will do the safekeeping of those keys. If such keys exist they will be abused.
