I was today in a cafe with my colleagues. Some among us was supporting that giving information to local, medium business, private information (such as register with member card, or giving information such us address, phone, email, etc) can be more good than a bad thing, and government already has the information that needs to know. We don't need to give false information to registrations, or not full-filling the form, or afraid anything. In the end, with our given data, we can be notified if we are winners in a random competition that the company is organized.On the other hand, the rest of us, supports that such small information and "small registrations", such registration with member card, registration to a website, all kind of registration forms electronic or not, can all together, be merged and analyzed, in such way that, in the end of the day, ends up with negative consequences against you. What is your opinion on these two sides?
