Challenges of the big data age

This is a big data age. America's Prism Gate has once again made the world feel strongly about this. Last year, a U.S. drama called "Suspect tracking" showed a "prism" project similar to an upgraded version. A genius designed a machine that collects information about almost everyone active on American soil, analyzes the data, and finds people who are at risk for U.S. national security, even people who are threatened by life or who pose a threat to the lives of others. Of course, information collection channels can not be separated from a variety of networks: telephone, credit card, computer ... "prism door" exposure let people realize, sure enough, did not do, only unexpected. Security and privacy in the big data age have long been a hot topic. American social thinker Toffler in the third wave, said, "If IBM's mainframe opened the information revolution of the big screen, then ' Big Data ' is the third wave of the CLS movement." "In fact, we have already started to enjoy the benefits of big data. For example, when you buy a book online, you can always see the list that the system recommends to you, and these books will basically not deviate from your usual interest. This of course than in the vast sea of books to find the book you want to facilitate a lot. It is only when we enjoy the conveniences of the information age that we are unaware of the various spotlights. Facebook users have been a little nervous for a while, as the results of the University of Cambridge Psychological Testing Center and Shine show that, with some special algorithms, it is highly accurate to judge his personal information from what a person "likes" (likes). For example, researchers can accurately determine whether the user is white or African-American, with a precision of up to 95%, and 88% of the cases to analyze whether the user is heterosexual or homosexual. This is just some very simple examples. "Prism Gate" and "suspect tracking" have shown us a more startling possibility. Anyone who lives in the information age, as long as it is intentional, seems to be under surveillance. How will people's lives be affected in such a world? How will national strategies be affected? The Obama administration last year announced the launch of "Big Data Research and development plan", the big data to the national strategy, will be the possession and control of the data as a Lu Quan, sea, air rights, another kind of national core capacity. In this new field of big data, the United States has once again come to the fore. How do you limit the misuse of large data? How to protect people's privacy? The big data age just kicked off, the world ready?
