Data filtering is becoming more and more frequent and it is in everybody's mouths. Increasingly, the discomfort of the population is becoming increasingly apparent, with the creation of some platforms for the population to control the entire sales process. In leaked data, Cambridge Analytics is the most popular: they took a lot of information from Facebook and favored Donald Trump campaign.
Even if things are changing, things need to be clear: if we surf the internet, we expand your data. For example, if you're using Google Maps, you're telling me where you are from Google. So there are only two options: accepting this situation or removing all applications from mobile.
In this way, if you want to sell your data, it can be done thanks to Blokchain technology. The creator of Word Wide Web (WWW), Tim Berners-Lee, has created the Solid Platform for users to find out who uses their data. According to Gregoy Barber, the only thing to register is, then the buyer will contact the users for the sale process per week. "They will provide you with cryptococci by data: bank movements, medical information, etc." It is up to the user to accept or refuse these coins. Chain blocks allow you to make a safe and private sale.
