Privacy is the edge between your personal, private information, and the need for information in the society.
Of course it would be nice if I could gather all information about my customers – and potential customers. Their shopping pattern, their sexual preference, their banking information. Their family and union registration. Employer, vage and tax-level. The number and types of cars you own – and also the previously owned vehicles. Then throw in housing, travell habits and your grades. And your military and social security information. Of course I use Internett to collect news, websites and images of you too.
I would then use this info to adopt marketing information. To help you get relevant offers. To make it easy for your to buy my products and services. So you do not have to source out the information yourself. After all, all I want to do is service you!
At some point I may start to use the information in a way that makes you unconfortable. I start to sell your special profile to the highest bidder. And you are not able to controll the information about yourself anymore.
This is still a scenario. But it is easy to do today. And powers are strong to get legal accept to do this kind of profiling.
You must take action yourself to protect infomation you'd rather not like used against you in the furture. Its time to wake up from the beauty sleep.
