Do you think the safety of surfing the Internet is a serious thing but you would like to better understand how to improve it? THE PROBLEM. While browsing online, I often had the feeling of being observed, that there was someone who knew what interested me, what I was looking for on the web. I remember one day I was looking for a Stan Smith pair that I liked, to compare prices, and finally turned off the computer without buying anything. The same evening I turned on the PC to visit a blog and here ... a banner appears with the advertisement of a pair of shoes. So I asked myself: is it a coincidence? No it was not. Giants of the web such as Google, Facebook and many others track the habits and interests of their users to profile them and sell this information to advertising agencies, drawing up a profile of our person.
