The curtains are drawn, always. That doesn’t affect the infrared cameras, but if you block those the Proctors come knocking to see why. Once you’re outside you are weighed and measured, sniffed, and biometrically interpreted at unknown but frequent intervals. The ident chip in your iComp bracelet records your movements for possible later reconstruction. Your eating habits, net footprint, health profile, sexual proclivities, political views if any, antisocial tendencies if any, cultural deviancy if any, are all available for official review on demand. You have nothing to fear if you have nothing to hide. You are as safe as houses.
