I wouldn't worry too much about spy planes and satellites invading our privacy because the instrument of citizen control is already right in our pockets. Who DOESN'T have a cell phone these days?
In the very near future, your cell phone will be the one single device required to do EVERYTHING. It's already started here in the Bay Area. You can now "load" your cell phone with credits which will allow you to ride BART (Bay Area Rapid Transit). Paying for bridge tolls and all public transit with your phone is next. Then it'll be concert tickets, groceries, gas, airline tickets, bar tabs, clothes and anything else you buy. Almost everything you do...everything you buy...everywhere you go....everyone you talk to will be stored and be accessible to those with a desire to know such things. Companies who want to sell you stuff will have a field day with this data. Your location can be pinpointed anywhere on the planet and your traveling and spending habits will be as easily charted as your web surfing is today. Let's say you get a speeding ticket one day. Maybe part of your punishment will be restricted access to bridges, certain toll roads or municipal parking lots....all easily arranged by simply sending a signal to your phone. Control of your cell phone will mean control of YOU.
