It's very easy. Our information is out there, even if we put out bogus information. You can imagine what my children go through. They have their online birthdays. On their real birthdays, their friends say, “happy birthday” and the algorithms pick up on that. The algorithms detect, by the volume of greetings on the real date, that it's the real birthday, along with the other information amassed through this hidden data broker system, where our information is traded, sold and bid on instantly.
The minutiae of our lives are available globally for sale.
