Spies and personal information or Smilely dosn't have a chance
Recent article made a point that with the techniques for gathering and filtering data it is now very hard and getting harder to play spy master. Gave Singapore as an example of max tracking. Ex.: Taxis all taxis have tracking beacons reporting to the central police station where the time spent on the run is compared against the standard and if it falls outside the range of error it is flagged. This is to protect the rider from gouging. Of course the cameras at the airport and hotel record a James Bond got in the vehicle and oh the person registering has now some other name! It was for that reason that consumer DNA kits are discouraged because that can be used to build a personal file. If in the days of key punch back tracking on a legend were possible, think now what is possible with petabyte files.
