If you really need to keep your information processing "private", then you can either isolate yourself inside a double-shielded room of solid copper; power everything with batteries; have no wires leading out of that room; make damned sure the door has the nice secure wiping strips to complete the shield when you close it -- or move your information processor into the middle of a whole bunch of the same or worse RF/RFI/EMI emitters, and just _maybe_ your data will get lost or become inaccessible because of the overload of the detection equipment by much larger interference fields.
Or use paper, pencil, and one-time pads and burn everything that's done "in the clear" and really scrunch the ashes into dust.

An interesting use of one time pads -- to keep one's own secrets. And where to keep the pads themselves? - Igor.
