The best thing about this is to tell us everyone: The big Data age has come, the information is open, the data nuggets are unstoppable.

YouTube achieved 4 billion of billions of dollars in revenue in 2012, rooted in the mining and application of large data.

It does so as long as the user wants to count and analyze, YouTube will give the data of almost all video.

Publicly available data has commercial value. Since the media age, all the behavior of people exposed to the sun, small to eat three meals a day, big to buy a house to buy a car, all the data in the network traces can follow.

There was an American man angry at Target supermarket: "You sent me to my high school daughter to mail the pregnancy product advertisement, want to encourage her to be pregnant?"

Privacy data corresponds to publicly available data. But what is the privacy data, and does not have a strict standard of judgment, for example, for ordinary people, shelter and so on are personal privacy, without permission, can not be exposed, businesses can not use this profit. Bloomberg's behavior was exposed by the media because it violated the privacy of its clients.

But for public figures, there is no privacy.

United States law stipulates that the state of personal property should be disclosed to the public before the President and the General Staff of the Government. This is a law that no one can override, and those who do not disclose property cannot enter the government to master the public good. So, every four years, the new cabinet nomination is the busiest time for the U.S. government's ethics office, and all candidates nominated by the President and required to be approved by the Senate must submit property reporting to the federal government's ethics office.

What China lacks right now is the protection of data privacy for ordinary citizens: you have just bought a house, and the information you buy will be sold to the decoration company. But the government's public information has done nothing.
