[comp.org.eff.talk] Store databases

Notice that not only can a store track your purchases, if they start logging 
your grocery tally, but they can also track your habits.  

"Ahah, Mr. Jones bought x groceries on Friday, and the Safeway across from 
where he works.  He shops there on Wednesday and Friday, after work, and stops
at the A&P at noon on alternate Mondays.  He buys dog food at the A&P, but 
general groceries at the Safeway..."  They can form a general picture of you 
and your habits by such tracking, enough that they can probably predict where 
you are at a given time, since most of us are creatures of habit.  If they 
know that Mr. Jones goes to shops near his mother's house every weekend, they 
can reasonably surmise he visits Mom.  Given such a profile, people can 
predict where you will be, at what times, and doing what.  The implications of 
the misuse of such information.  

As a matter of fact, if someone tracked your gasoline credit card purchases, 
they would have another means of keeping tabs on your movements.  Big Brother 
can watch you, everywhere.
